1.1 Use of Audio-Visual Aids in Teaching and Learning

Using audio-visual aids in teaching and learning has revolutionized education, offering an innovative and dynamic approach to classroom instruction. Audio-visual aids incorporate visual and auditory elements into the teaching process, such as videos, images, animations, and sound clips. These aids have proven invaluable tools for educators, as they enhance comprehension, engage students, and create an interactive learning environment.

One of the primary benefits of audio-visual aids is their ability to make complex concepts and abstract ideas more accessible and understandable. Visual aids, such as charts, graphs, and diagrams, provide students with a visual representation of information, enabling them to grasp difficult concepts with greater ease. By presenting information in a visual format, educators can simplify complex ideas and make them more tangible and relatable to students.

Moreover, audio aids, including recorded lectures, podcasts, and audio clips, provide an auditory reinforcement that complements visual materials. Hearing explanations, discussions, and examples can reinforce learning and deepen students’ understanding of the subject matter. Audio-visual aids create a multi-sensory learning experience that caters to different learning styles, accommodating visual and auditory learners.

In addition to enhancing comprehension, audio-visual aids promote active participation and engagement among students. When exposed to visual and auditory stimuli, students are more likely to be actively involved in the learning process. Multimedia presentations, interactive whiteboards, and educational videos captivate students’ attention and stimulate their curiosity. This engagement fosters a deeper level of understanding and encourages critical thinking skills as students analyze and interpret the visual and auditory content presented to them.

Furthermore, the use of audio-visual aids encourages collaborative learning. Students can engage in discussions, group activities, and multimedia presentations, fostering teamwork, communication, and cooperation. By incorporating audio-visual aids, educators create an interactive classroom environment that encourages students to share ideas, ask questions, and learn from one another. This collaborative approach enhances students’ social skills and promotes a deeper understanding of the subject matter through peer interaction and exchange of perspectives.

Audio-visual aids also offer the opportunity to bring real-world examples, case studies, and practical demonstrations into the classroom. Educators can bridge the gap between theoretical concepts and real-world applications by incorporating videos, virtual reality simulations, and interactive multimedia. This hands-on approach enables students to see the practical relevance of their learning, making the educational experience more meaningful and applicable to their lives.

While audio-visual aids have countless benefits in teaching and learning, educators need to use them purposefully and effectively. Proper planning and integration of audio-visual aids into the curriculum are crucial to ensure alignment with learning objectives and the needs of students.

Students often find it easier to comprehend and remember information when it is presented in a visual format. Complex processes and relationships can be simplified through visual aids, allowing students to grasp intricate details that might be challenging to convey through text alone.
  • Auditory Learning: Not all students learn the same way, and audio-visual aids cater to auditory learners by incorporating elements such as audio clips, podcasts, and relevant sound effects. These auditory components reinforce the material and provide an alternative avenue for understanding. Whether it’s a historical event’s narration or a scientific phenomenon’s explanation, audio elements can create a more immersive and memorable learning experience.
  • Interactive Learning: The interactive nature of audio-visual aids adds a new dimension to the learning process. Simulations, virtual labs, and educational games allow students to engage with the material actively, turning passive listeners into participants. Virtual experiences provide a hands-on approach, enabling students to experiment with concepts in a controlled environment. This form of active learning enhances understanding and fosters critical thinking and problem-solving skills.
  • Variety in Teaching Methods: A diverse range of media formats accommodates different learning styles. By presenting information through a mix of text, images, audio, and video, educators can appeal to a broader audience. Documentaries and case studies bring real-world examples into the classroom, making lessons more relevant and captivating. This variety of teaching methods caters to students’ preferences, making the learning experience more personalized.
  • Increased Retention: Visualization of abstract concepts through audio-visual aids significantly increases retention. When students can see and hear information simultaneously, it becomes more memorable. The combination of visual and auditory elements facilitates a deeper understanding of the material, and the reinforcement through multimedia aids in long-term retention.
  • Personalized Learning: Audio-visual aids lend themselves well to personalized learning approaches. Self-paced learning modules, customizable content, and digital platforms allow students to learn at their speed. Teachers can tailor materials to match their students’ diverse learning preferences and needs, fostering an environment where each student can thrive.

1.4 In what ways do audio-visual aids contribute to better understanding and retention of information among students?

Integrating audio-visual aids into educational practices has become a cornerstone in fostering a profound understanding and improved retention of information among students. This dynamic combination of visual and auditory elements creates a rich, multisensory learning environment that accommodates diverse learning styles and engages students on multiple levels.

Visual aids, such as charts, graphs, and diagrams, are pivotal in simplifying complex concepts. These graphical representations serve as visual cues, making abstract ideas more tangible and accessible. For instance, in science, intricate biological processes are brought to life through animated diagrams and 3D models, enabling students to visualize and understand the inner workings of living organisms. Visual aids provide a crucial scaffold for comprehension, breaking information into digestible components and facilitating a deeper understanding of the subject matter. Simultaneously, auditory elements contribute significantly to the learning experience. Lectures, discussions, and educational podcasts offer an auditory dimension that complements visual stimuli. This is particularly beneficial for auditory learners who grasp information more effectively through listening. Combining spoken explanations and visual aids provides a comprehensive learning experience, reinforcing key concepts through multiple channels. Moreover, the strategic use of sound effects and music can create an emotionally engaging atmosphere, enhancing the overall impact of the learning material.

The interactive nature of audio-visual aids is instrumental in promoting active participation and hands-on learning. Educational games, simulations, and virtual labs transform the learning experience from a passive reception of information to an engaging, interactive process. Students become active participants in their education, experimenting with concepts and applying theoretical knowledge in practical scenarios. This enhances comprehension and fosters critical thinking skills, contributing to a more holistic understanding of the subject matter. Repetition is a fundamental aspect of learning; audio-visual aids facilitate this through various means. Visual materials can be revisited, reinforcing the information through repetition and creating a more lasting impression. Additionally, the auditory repetition of key concepts through recorded lectures or discussions contributes to memory consolidation. The combination of visual and auditory repetition strengthens neural connections, making it more likely for students to retain information over the long term.

The adaptability and accessibility of audio-visual aids in the digital age contribute to a more flexible and personalized learning experience. Online platforms, interactive whiteboards, and digital resources enable students to access educational materials at their own pace and convenience. This self-directed learning empowers students to revisit content, reinforcing their understanding and allowing for personalized exploration of topics of interest.

In conclusion, incorporating audio-visual aids into education represents a powerful strategy for enhancing understanding and retention of information among students. By appealing to diverse learning styles, providing interactive experiences, facilitating repetition, and leveraging digital technologies, these aids create an environment where learning becomes informative but also engaging and memorable. As education continues to evolve, the strategic use of audio-visual aids stands as a testament to multimedia’s transformative potential in shaping today’s learners’ educational experiences.

Use of audio visuals aids in teaching and learning

The use of audio-visual materials in education is crucial today since it improves student learning. This is one of the reasons why the usage of audio-visual aids in teaching and learning has grown over time. Students can now share knowledge with others much more quickly and with instant access. Additionally, learners can now comprehend ideas and concepts more quickly and better. There are numerous different audio-visual aids accessible in the modern world such as videos, music clips, flip charts, slideshow presentations, and overhead transparencies there resources have proven essential in schools across all learning environments, from early childhood education to adult education. With the use of these resources, children have been able to concentrate more readily and acquire and remember more knowledge. As audiovisual technology has become more widely used, communication has changed and teachers can use these advances in the classroom to enhance teacher-student collaboration.

Teaching aids, according to Sunder (2010 ), improve teaching ability, draw in and hold learners’ interest, and make the teaching-learning process more participatory and knowledge-centered. In order to make the teaching-learning process result-oriented, simple, efficient, and interesting for both teachers and students, there is a clear need for and importance of teaching aids.  When it comes to teaching a new or abstract idea that could be challenging to understand or comprehend, audio-visual aids are essential. Teachers can show concepts to students using audiovisual aids in cases when they might otherwise be difficult to explain. I am a science teacher and I remember when I was teaching in a school in India most of the students faced difficulty to learn difficult topics such as photosynthesis, the naming of a chemical compound, and mole concepts. At that time, I usually used audio-visual aids so that students can understand the concepts easily.

Moreover, different people have various ways of processing, absorbing, and remembering information. Some people are aural learners, meaning they process information best by hearing it rather than reading it. Others, who prefer to learn by looking, are visual learners and respond better to information presented in this manner. teachers can appeal to at least two different learning styles by using audiovisual aids while presenting the material. Additionally, Udomon, Xiong, Berns, Best, and Vike’s (2013) study on the effects of visual, and auditory on memory retention and recall showed that using two or more senses to learn information greatly improves retention and recall. The likelihood that information will be remembered is higher when it is delivered in both audio and visual formats. These tools generally help students better engage with the information and motivate them to study and they make it possible to communicate information in greater depth and detail.

Furthermore, The children’s television program Sesame Street was the first of its kind to use a precise and thorough educational curriculum, with specified educational aims, in its material. Sesame Street had its public broadcasting television debut in 1969. The show’s outreach objectives were met during its first season by a comprehensive and ground-breaking promotional campaign that was directed at children and their families living in low-income, inner-city homes because these populations tended to not watch educational television programs and because conventional methods of promotion and advertising were ineffective with them. A number of instructional resources for preschool settings were created by the producers for later seasons. According to a study published in the journal Early Childhood Education by Television: Lessons from Sesame Street , Sesame Street viewers, in particular those from lower-income areas, were found to be better prepared for school than their counterparts who did not watch Sesame Street. In comparison to their peers, children who watched Sesame Street scored higher on tests in science and English, had higher overall GPAs, read more books, valued achievement more, and were seen to be more creative.

In conclusion, audio-visual aids are essential to learning in a variety of ways, including the fact that they can be used with different learner types. Additionally, by connecting the audio-visual tools to the outside world, educators can use them to motivate students by demonstrating how the ideas they have learned can be used. The use of audio-visual aids in teaching and learning is advantageous because they engage the learner’s eyes, ears, touch, and possibly feelings in addition to their senses of sight and sound.

I appreciate your thoughts and experiences working with children using audio-visual materials. I agree Digital learning taps into this easy access to information and helps students to use it effectively. A good digital learning strategy also teaches students how to be objective when searching the internet for information.

I enjoyed reading about how you use AV for science. Science is definitely not my favorite to teach, so I find myself using a lot of videos, documentaries, and pictures to explain concepts. Especially when teaching French Immersion, some concepts can be extra difficult to explain when it’s not our first language. I even watch videos first to understand so I can teach my students properly.

Chapter 8, Using Audiovisual Aids

This chapter will help you

► recognize the purposes for visual aids in training

► identify the types of visual aids

► understand the four rules for use of visual aids

► design appropriate visual aids for your material

Introduction

The often-quoted comment in public speaking is that a picture is worth a thousand words. If the picture is clear, can be seen by all, and relates to the message, the expression holds true. If not, you are better off using a thousand words. We have not forgotten a former student of ours who heard us talking about the value of the media, particularly the use of slides with an audiotape. For his demonstration, he decided to use four slide shows with four separate audio messages, all playing at the same time. Needless to say, his points got lost in the media presentation, and we certainly had a good example of noise pollution for the class to discuss. Unfortunately, that was not the purpose of his message. In this chapter we would like to talk about the ways in which you can enhance your training material by using audiovisual materials. We will cover all of the technology that is available to you as a trainer, including the use of a computer.

As you recall from previous chapters, you have conducted the needs assessment and decided what programs you are going to present in your training sessions. Once you have designed the program, developed your objectives, and planned your lecture material, you can begin to think about and plan what audiovisual aids you will use to enhance the material that you plan to incorporate in training.

We hope that you will think of other ideas beyond the traditional audiovisual aids such as flip charts, chalkboards, films, slides, and overheads. We want you to think about magazine ads, Tinker-toy building blocks, and Play-Doh modeling clay, to name a few, as other perhaps more innovative ways to enhance your training. We have even seen trainers use trainees as live visual aids to make a point.

Now that we have aroused your interest in Play-Doh, we do not plan to write a definitive treatise on its use in training sessions. Rather, we would like to explore some of the traditional ways to enhance your training and then discuss, at least on an introductory level, some of the nontraditional ideas that we have found successful. If you choose to develop your skills in training beyond this introductory presentation, we would recommend two specific behaviors to you. First, you can read materials that are listed in our bibliography on audiovisual techniques and strategies. Second, you can take a course in instructional technology and development that might be available at a nearby college or university. Either way, you should go on and explore audiovisual materials in more depth than we can provide in this introductory chapter.

As an overview, we would like to talk first about the purposes of audiovisual aids, when you should use them and when you should not use them. We will then discuss each of the various types of audiovisual aids, when that specific aid is appropriate, and for what size group you should use it. We will conclude the chapter with a discussion of what we consider to be some of the nontraditional a/v (audiovisual) materials.

Purpose of A/V Materials

The purpose of visual aids is to enhance the message you are trying to get across to your trainees. If you are using audiovisual material as a gimmick, it will certainly come across that way to your training audience. If you use too many of them, or inappropriate ones, that too will be perfectly clear. We have probably all heard stories of teachers who dress up in period costumes in order to teach history, as in dressing up as Shakespeare to talk about fifteenth-century England. This could be a very effective use of visual aids if we remember what was discussed rather than that the teacher dressed up as William Shakespeare. It is more important to make Shakespeare’s literature come alive than Shakespeare himself.

There are a number of things that should guide you in answering the question, “Should I use a visual aid?” First and foremost, if the visual aid—a slide, a video, computer graphic, a handout—will enhance the basics of your training program, then you should certainly use it. If a picture can convey more than simply words, then you should consider the use of a/v materials. A series of slides showing the various components of a computer word-processing system could be far more effective than just talking about it. Finally, if you view the audio-visual aids as a way of helping the trainee remember the content of your training program rather than the way in which you used the visual aid, then you should consider incorporating audio-visuals into the training package. As we suggested earlier on developing training materials, and as we suggested at the beginning of this chapter, consider audiovisual aids only after you have developed the full course content. Go back over your training materials and decide what would be an appropriate place for the use of audiovisuals.

On the same score, there are a number of things you should keep in mind in regard to when it would be inappropriate to use visual aids. If you find that you have incorporated too many a/v materials like our student described in the beginning of this chapter, then it is time to back off and cut out some, if not all, of your a/v supplements. Too many aids can spoil the effectiveness of a sound training program.

You should also keep in mind how much time you have in order to prepare audiovisual materials. If your overheads are sloppy, if your videotape is poor quality, or your audiotape can’t be heard, you are better off not using these poorly prepared materials. Remember, your image is at stake, in addition to the presentation of the training program. We don’t know for certain that good visual aids will add that much to a training program, but we do know that poorly prepared a/v materials can detract from the overall effectiveness of our training.

Finally, you should not use visual aids if they are either scheduled at an inappropriate time or are inappropriate for the nature of the content. Showing a series of slides because it is time for diversion is not making effective use of a/v materials. We recall a colleague who used slides for a session on relaxation and stress. The trainees commented that the slides looked more like the trainer’s vacation pictures than pictures designed to promote relaxation. Our colleague confessed they were right and he had learned the valuable lesson that these slides were inappropriate for this group. We are also reminded of a colleague who taught all of his classes by stringing together films and videotapes with little other material. Students confessed lots of sleep time and little learning.

We have but four simple basic rules that we subscribe to in the use of audio-visual aid in training programs. If these four general rules are kept in mind, use of a/v materials can be very effective.

Rule No. 1: Audiovisual aids should be confined to a single concept . For example, if you were to use an overhead you might want to focus on only one issue per overhead. You would certainly not want to cover the history of the theories of management all on one overhead or slide. The same principle applies to video – you would not want to play thirty minutes of tape on management principles when all you really wanted to discuss was leadership style. You would be far better off to play only an excerpt from the tape that confines discussion to the single concept. You might even want to create your own video or use live role-playing as the visual aid.

Looking at Exhibit 8.1, we can see an overhead that has lots of information but is cluttered with materials that, on the surface, do not relate well to each other. Are these factors of training evaluation or productivity? Does each item in the list have equal value? Only our trainer knows the relationship of the items on the overhead. In the second example, Exhibit 8.2, the trainer wants to remind the trainees of the two major types of training evaluation. If in fact, a participant in the training program could probably figure out what was meant with this visual aid without any other notes from the training session. This overhead is straightforward and uncluttered.

Rule No. 2: Make sure that every member of your training audience can see and/or hear the audiovisual aid . If you are playing an audiotape, you should determine in advance, that everyone, regardless of where they sit in the training room, can hear the material on the tape clearly. If you are using a micro tape recorder for an audience of 150, you had better make sure that you have a microphone or some other form of amplification so that all can hear the material. Showing 8 x 10 photographs to an audience of more than five or six would be another violation of this general rule. You would not pass around this book to show everybody the above exhibit. If all trainees cannot see it, or if they cannot hear it, you have made inappropriate use of your audiovisual aid.

Rule No. 3: Maintain control of your audiovisual . What does this mean? The beginning student in a public-speaking class perhaps is most guilty of violating this rule. When told to use visual aids, invariably a student will come with a series of pictures of his or her summer vacation. As the student progresses through the talk, the pictures begin circulating among fellow students with those at the beginning anxious to see each and every picture and those in the back of the room recognizing that they may never get to see them. If everybody cannot see the visual aid at the same time, you have lost control and you are better off not using the visual aid. The same student could have put the pictures on slides and thus maintained control of the visual, as well as guided the audience, or in our case the trainees, through the program simultaneously.

Keeping control also means that you have planned ahead for the use of your particular visual aid. If you are going to use a chart, make sure you have a place to set the chart that will allow it to remain in its full and upright position throughout your discussion. The last thing you want to be doing while discussing any audiovisual aid, such as a chart, is trying to hold it up so that it doesn’t fall off the chalkboard or away from your training podium. You may even have to pay to have a trainee hold the chart if there is no other way to insure control.

Rule No. 4: Watch out for Murphy’s Law . The most famous law, “If something can go wrong, it will” appears to apply most appropriately to audiovisual aids. How do you avoid this curse? Probably, you can’t prepare for all of the eventualities. Traditionally, you will carry extension cords, extra light bulbs, additional magic markers and chalk. Even that doesn’t protect you from the evils that lurk in the training session. We recall once carrying an overhead projector, complete with the additional bulb, the long extension cord, and markers some two thousand miles to present a training program. We went down and looked in the room to make sure there were electrical outlets within distance of our extension cord and that the screen was there and that everyone could see it, in spite of several columns strategically placed throughout the room. Thus, we felt fairly confident that we had followed the general rule and would avoid the pitfalls of Murphy’s Law. Needless to say, we were in for a big surprise when we set everything up, plugged in the overhead, and began the training program. At the point when we were to introduce the first overhead projection, we flipped the switch. Nothing happened. A quick check soon revealed that Murphy had struck again, Not only did the electrical outlet that we had used not work, but none of the electrical outlets in the entire room had power. Fortunately, we were not willing to let Murphy’s Law overcome the situation, as we had prepared all of our overhead projectors as handouts and were able to proceed without the use of the projector.

Perhaps the converse of this rule is most appropriate, and that is “Plan ahead and be prepared.” Check out every conceivable pitfall that may befall you as you are using visual aids. If you have rehearsed your presentation with visual aids, try to do so in the room in which you will be providing training. Thus, you will be able to avoid Murphy striking you.

Specific Visual Aids

In our discussion of specific types of visual aids, we will look at each one of them from the point of view of how to use it, the optimum size of the audience for that visual aid, and the advantages and disadvantages of that visual aid. We will look at the aids by categories, beginning with written visual aids such as overhead projections, chalkboards, flip charts, and handouts. The second category will include audiovisual aids. The third category will include all other visual forms of aids such as films, slides, video, and computer-generated materials. We will conclude by talking about some of the nontraditional aids described in the beginning of the chapter.

Written Aids

When we think of traditional visual aids, we immediately think of using the chalkboard, flip charts, and handouts. For the most part, these types of visual aids simply highlight in writing, those concepts that we are discussing orally. We use these aids to underscore our message, and to aid the trainee in remembering what we have talked about. They also serve the purpose of helping us maintain an outline and a flow for the material as we present it. In fact, some trainers have all of their notes in outline form on overhead projections and thus appear very organized because they can speak without having notes in hand or on the lectern.

The first and often used, written a/v type is the chalkboard, or the modern variation, the wallboard, on which we can use erasable markers. Modern training facilities have gone with the latter approach as it is less messy and does not create the squeaking sound that chalk tends to as we write on the board. A chalkboard is most useful for highlighting particular words and a quick drawing of rather elementary graphs and tables. Its obvious advantage is that it is easy to use and can be done quite spontaneously. Unless you have a series of boards that can be hidden from view, however, you really cannot prepare materials on the chalkboard in advance of the training program. Chalkboards offer a limited amount of space on which to write, and can be messy. The optimum audience size could range from one to probably not more than twenty-five or thirty.

Like the chalkboard, the flip chart can be used for highlighting specific words, or contents, as well as presenting graphs and simple tables. It, too, is easy to use, is relatively inexpensive, and the materials can be displayed in advance and revealed to the audience as needed. Pages also can be removed from the pad and attached to various walls around the training room for further use in the training session. On the other hand, the flip chart requires some kind of stand to hold it up and because of its size, limits the size of the audience for its effectiveness. It probably is optimal between five and twenty to twenty-five trainees.

The overhead projector moves you into more advanced media requiring both some kind of projection and a screen, or at least a wall, for the image. Like the chalkboard and the flip chart, the overhead projector is useful for displaying key concepts, graphs, and tables. In addition, one can make overheads of anything that can be put through a copy machine. This means that even color photographs can be first copied on an overhead transparency and then projected to an audience. Thus, you have greater flexibility with the use of overhead materials.

On the positive side, materials for overhead projectors are relatively inexpensive and are fairly easy to prepare. One can also use the overhead in a spontaneous way simply by writing on clear transparencies in the same way that you would on a flip chart or on the chalkboard. On the other hand, effective use of the overhead projector requires advance preparation, as well as the purchase or rental of such equipment. The optimum size audience for an overhead, ranges from five to approximately one hundred. If the audience approaches one hundred, you will find that a large screen, 25 x 25 feet, may be necessary and that you will be farther away from your overhead projector so that you will not have the flexibility of being able to write on the projector transparency and still be in front of the trainees. Thus, using an overhead for an audience of more than twenty-five or thirty can prove quite cumbersome and unwieldy. You will need an assistant just to change the overheads because you will be far from the projector if you plan to stand in front of the trainees.

We should also talk about the latest variation on the traditional overhead. We now have the capability to generate overheads on a computer and display them on either an overhead projector or a television screen, depending upon the type of conversion device used. The equipment used to convert a computer-generated image for display on a television screen can be quite expensive. Regardless of the method used, remember the earlier rules regarding the ability of the audience to see and hear the material.

A piece of equipment out of the dark ages that has pretty well lost favor and should not be in your training repertoire is the opaque projector. This equipment is designed to project printed material from the page onto a screen. Given copy machines and the development of overhead transparencies, we seldom, if ever, see an opaque projector. The disadvantages far outweigh the advantages in that it requires a room with total darkness and a piece of equipment that is very large and cumbersome. The appropriate audience size would be much like the other three previously discussed.

The last form of written visual aid we discuss is handouts. There are several varieties of handouts that you can use with trainees, ranging from simple outlines to incomplete notes in which the trainee provides the additional information you discuss in the training program. Another type of handout is a collection of essays and/or articles. You would use these various types of handouts at different times during the training program. For example, it is best to present an outline before the training program so that the trainee knows where you are headed. If the handout is a series of incomplete notes, this might be appropriate for use during the training program so that the trainees can fill in the missing blanks. If you are handing out supplemental material or a series of essays, then it would be best to provide this after the training program. Remember, any handout material you provide the trainees can serve as a diversion from the training material you are discussing.

While the authors like handouts, we are well aware of the pitfalls of their use. We try to provide our hand-outs as needed, rather than providing the entire packet at the beginning of the training program. You can see the advantages and disadvantages of this approach. If you provide all of the materials at the beginning, you should be prepared for the trainees to wander through the training packet during the initial portion of your training program. If you provide each handout as needed rather than as a total packet, you need to find an orderly way to distribute the material. It can be very disruptive if frequently during the training program you have to pause to hand out the necessary material. This interrupts the flow of your training, can be disruptive, and can cause the effectiveness to diminish. On the other hand, we prefer handing out materials as needed so that we can use the material in any order that fits our needs at that point. It also allows for the flexibility to skip training handouts because the trainees already understand the concept. For example, if you have three different handouts on the use of interviewing techniques; you may need only one to get your point across. If you feel the others are valuable, you can always provide those at the end of the training program as supplemental material. On the other hand, if it is in a training packet that you have handed out in the beginning, you will feel obligated to go through all of the materials in the prescribed order: otherwise the trainees will be confused by going from page 1 to page 27, back to page 2, and so on.

We further feel that handouts are useful as an audiovisual technique because they help the trainee after the training session is over. We believe they serve as an aid to memory; as a trainee in one of our workshops put it, they became the bible for his training in presentation skills. In fact, after the pages became ragged, he called us for a new training program for his new employees because he felt the manual was a good tool that he could use almost on a daily basis.

There is really no limit to the number in your audience for the use of handouts. The only word of advice we would give is the larger the audience, the more it may be necessary to put your handouts into a packet to be given to trainees at the beginning of the session. One can really not take the time to wander among two hundred participants each and every time a new handout is needed. Therefore. you would provide the training packet at the beginning and would be expected to go through all of the material.

As you will learn in the next chapter, it is now possible to develop a series of overheads/slides using the computer. These slides can be printed one or more to a page as a series of handouts to reinforce the message.

Audio Materials

Cassettes, records, and discs can also serve the trainer in the presentation of materials. As with all a/v aids, their use depends on the type of material covered and the points you are trying to make. We have found audiotapes to be quite useful as illustrations for a particular point, or to make examples to which trainees can respond. For example, if you were discussing the various types of empathic listening, you might put samples of dialogues on tape and ask the trainee to pick out which type of listening the person on the audiotape was doing. Audio tapes are relatively easy to produce, can be inexpensive, and are easy to use. With modern technology, audiotape recorders are fairly portable and with a microphone or an external speaker, can usually be heard by all members of the audience. On the other hand, overuse of audiotapes, because they lack the visual quality, can be somewhat boring to training participants.

There is really no limit on the size of your training audience for audiotapes and cassettes as long as everyone in the audience can hear them.

Visual Aids

In the category of audiovisual aids, we would include slides, film, videotapes, and computer graphics. These a/v types are the most stimulating for a training audience, but are the most difficult, time consuming, and expensive to use. Do not let that deter you from their use when it is appropriate for your training program.

The advantages of such visuals as slides, films, and videos are different for each, but the disadvantages are pretty much the same. The audience has to be of limited size, probably not more than twenty for videos, unless you have a number of monitors, and not more than one hundred for slides, or you will not be able to get a screen large enough to project an image that can be seen by everyone. The equipment is relatively expensive, but is rapidly becoming less expensive as new technology produces smaller and more compact units, particularly in the area of videotape.

Using professionally prepared slides, films, and videos can be quite expensive, because the supplier needs to build the cost of preparation and presentation into the actual expense of the film or videotape. For example, it can cost as much as $800 or $900 for a 20-minute film or video presentation. Prepared slide programs are also expensive, but are in the $100 to $300 range.

The advantage of using slides is that they are relatively inexpensive if you prepare your own, and are easy to use and quite portable. All of the advantages of the overhead projector can be duplicated by using slides, and you can develop sequence of items far more easily using slides than using an overhead projector. An additional benefit of using slides is that it is easy for you to develop vignettes or case studies for use by the training participants. In fact, you can develop a series of vignettes and ask the participants to follow through, expressing the outcomes of each of the scenarios you develop.

Films are advantageous because they allow you to present concepts in a process from where motion and a visual display are important. For example, you can have a film to demonstrate inappropriate leadership styles in management in an organization. The same can be said for the use of videotapes as can be said for films.

Many college and university facilities provide film and videotape libraries that are for rent at a nominal cost. If you have access to such materials. they can enhance your training program. If you make your own videotapes. you will need to find some kind of a facility that will allow you lighting and limited editing equipment so that you can produce a video of quality equal to the rest of your training program. If your videos look homemade, you will create that impression with the trainees.

You might also consider videotaping portions of existing television programs to make your particular point. For example, when we are discussing the various forms of influence on individuals, we can use commercials prepared for the mass audience and discuss the various types of influence that are used by the advertiser. Vignettes from soap operas, evening television performances, and news pro­grams can also be incorporated into videos to highlight points in your training program. Needless to say, all of this takes extra effort on your part in order to collect, edit, and use television as part of your video package. Note: Be cautious in using copies of television material because you do not want to violate copyright laws by copying and distributing these homemade collections.

Computer Graphics

While we will discuss the computer in more detail in the next chapter, we should point out that the computer offers a unique opportunity to generate graphics in the form of tables, graphs, and other charts that can be useful in combination with the more traditional forms of visual aids. Most software programs provide for the generation of computer graphics that can be used in training materials. The computer also offers the opportunity to generate free-form graphics through the use of an art boar, which is available for most computers in the moderate to expensive price range. You should check with your local computer outlet to determine what is available for the kind of machine you have access to.

Computer Combinations

We have labeled this section a combination since the computer allows you to combine video, audio, pictures, and graphics into an output which then can be projected to a training audience via a conversion device. For example, you could develop a computer presentation that talks about different types of speech introductions by presenting first a word label followed by a brief audio/video within the computer presentation. The trainer could stop; ask questions; replay the video; and move on to the next segment. This same program could be developed into a self-taught computer package that a trainee could complete. Every day we get more and more sophisticated possibilities from computer applications. Check your favorite computer software store for the latest possibilities.

Nontraditional Aids

All of the audiovisual aids discussed so far are traditional in the world of training and development. There are a number of other items that you should also include in your repertoire of enhancements for training. You may be familiar with some of these, but we would certainly recommend that you look at them as viable options for your training presentation. These nontraditional aids include Play-doh modeling clay, Tinkertoy building blocks, pipe cleaners, puzzles, and magazine pictures. We would also include in this category all three-dimensional objects, which we might label as props. In addition to serving the usual role as a/v aids, these nontraditional forms can heighten the interest of your training audience. When conducting workshops on stress, we sometimes introduce Play-Doh modeling clay as a form of stress reduction. When we look at workshops on team building and small-group exercises, we use Tinkertoy building blocks as a bases for group activity. The same could be said for other props, as well as pipe cleaners and puzzles.

You should not overlook the use of pictures, ads, and other materials from the printed media, as they too can serve as a form of audiovisual aid. As we mentioned earlier, when we are talking about the role of influence in communication, we use television ads; the same could apply to magazine ads. When doing a workshop on creativity, the advertisement by the SAAB Motor Company as an illustration of right/left brain and the thinking process can be used. This is a good ad that caters to both the right and left brain (if you use and accept this approach) by providing a visual image for the right brain and a very analytical description of data about the car for the left brain.

The use of nontraditional forms of audiovisual aid is unlimited. Anything that can be used to demonstrate a point, add interest, or generate enthusiasm can be considered as a visual aid. Our only requirement is that the aid fit the particular point we are trying to make, rather than simply introducing it because it happens to be novel. We recall a speaker once who had a paper bag sitting on the podium through most of the presentation. At the appropriate moment, the person reached into the paper bag and pulled out several stuffed animals. He described the conformity of board members of the foundation like a row of ducks, saying yes when asked. Needless to say, the visual aid was well received and proved to be quite memorable.

In conclusion, then, there is a wide variety of audiovisual aids that can be used to enhance your training program. Let us underscore that whatever aid you select will work if it is appropriate for the material, as well as for the trainees to whom you will be presenting it. You cannot overprepare i.e., making sure that all of the problems that can go wrong won’t. Keep your aids simple, direct, to the point, and related to your discussion. Plan for failure. A wise person once advised that you should keep candles in your training packet, because when everything in terms of your visual aids goes well, there is always the chance that the lights will go out from a power failure. If this happens, relax, maintain your composure, and hope that the power will go back on quickly.

Audio Visual Aids

Audio Visual Aids facilitates the task of a teacher while teaching in the class room. These aids are very useful at the el ementary and junior stages. The use of audio-visual-aids has mechanised the education and teaching learning process.

These teaching aids are used to facilitate both audio and vi sual senses and encourage listening and observing functions. Thus these aids involve more than one sense simultaneously and learner more active. These aids develop the perception of the learner which is the basis for the understanding of any concept.

Audio visual technology is related with instructional technology.Broadly speaking, audio visual aids include all the vari ous means and techniques which a teacher may collect from his resources and display them to make the teaching appear real as well as affective.

Teaching aids can be classified into three main categories :

1. Audio Aids

2. Visual Aids

3. Audio Visual Aids

Audio-Visual Aids

Audio-Visual Aids

1. Audio Aids : Aids which appeal only the ears are called audio aids. For Instance: Headphone, Radio, Tape-recorder, Gramophone.

2. Visual Aids: Visual aids appeal only to eyes. Following are the main visual aids: Picture, Film strips and slides, flash-card, flannel-board, black board, text books, charts, maps, models etc.

3. Audio Visual Aids: The aids which appeal to both eyes and ears are called audio-visual aids. For example: Television, Cinema, films.

We can divide audio-visual aids into two broader categories:

(1) Cheap aids, (2) Costly / Expensive aids.

(1) Cheap aids – Charts, maps, text-books, black-board, flan nel- board etc.

(2) Costly aids – Film, television , slides and film strips etc. Some other audio-visual aids are as follows:

1. Teacher- Teacher is the most suitable and effective au dio-visual aid. He can explain things more vividly with the help of gestures and modulation.

2. Simple and flexible objects – The teacher can use some aids like flannel board, bulletin board, black-bord, chair, duster, table, pencil etc. He can use them wherever and whenever he feels the need.

3. Reading material – Books, Magzines, Journals, Story Books etc. also serve the purpose of material aids.

4. Graphic Aids – Pictures, Charts, Sceneries, Maps, Cartoons, posters, etc. are also used as graphic aids.

5. Sophisticated Aids – Electronic items like computers, record, players, record-players, projectors, transparencies, tape re corder, radio, television etc.

6. Activity material- These are fieldtrips, flash card, puzzles, crosswords, word building cards, matching words etc.

7. Cultural Media- Dance, drama, puppet show, song etc.

8. Miscellaneous – Pamphlets, exhibition etc.

Different types of Audio-Visual Aids in Education

Back to: Educational Technology in Education B.ed Notes, M.A Notes, IGNOU Notes

The audio-visual types of equipment and materials can be classified in several ways according to different approaches. Most of the visual aids can be grouped into the following categories:

  • Projected Aids and
  • Non-Projected Aids

image 17

Projected Aids with examples:

Projected aids are those that require audio-visual equipment to be presented properly. Some of the aids included in this category are slides, filmstrips, overhead projectors and motion pictures.

  • Projectors: Projectors are those types of equipment which are used for being visualized by the learners to gain useful learning experiences.
  • Filmstrips: A filmstrip is a series of related still photographs on a single roll of processed film. They may be produced in black and white or coloured and are sometimes accompanied by sound recordings which carry narration, music and sound effects.
  • Motion Pictures or Film: Recently motion pictures have received extensive use in training and information programmes. A film is a multiple method of communication, it realistically presents facts, arouses emotions and transmits attitudes. It is mostly used as a storyteller. The main aim of educational films is to evaluate and educate them according to patterns and principles set by society.
  • Overhead Projectors: It contains an area of vertical projection beside the straight horizontal path of the light available with the usual projectors. It also contains a large aperture of size. It provides for the focusing of the image on the screen by vertical movements of the projection head.
  • Slides: are very popular in teaching, they are inexpensive and can be quite easily constructed and stored, and may be used countless times.

image 18

Non-Projected Aids with examples:

Non-Projected aids are those aids that don’t require the use of audiovisual equipment such as a projector, filmstrips, and screen.

  • Graphics: Graphic aid material represents a particular type of visual aid material that involves the use of graphic presentation in the form of graphs, maps, charts, diagrams, posters and cartoons etc. It is a sort of visual art that carries a symbolic abstract and generalized representation of reality, there are some important graphic aids given below.
  • 3-D Aids: Three-dimensional aids are powerful interest arousing devices that possesses the capacity of bringing into play all the five senses. Few such three-dimensional aids are named under:
  • Display Boards: as the name says all the types of boards that can be used for displaying graphics and material like pictures, charts, diagrams, and cartoons, besides all types of written, typed and printed material that can be used for the visual communication of ideas and experiences.
  • Blackboard or Chalk board
  • Bulletin board
  • Flannel board
  • Audio Aids: The aids which use the sense of hearing are called audio aids. Radio, audio tape or tape recorder players are generally included in this category.

Making the Most of Visual Aids

Three strategies for using visual aids to encourage students to engage more deeply with course content.

Teacher standing next to a blackboard that has a diagram drawn on it. She is pointing off-camera.

Most teachers understand the power of visual aids in helping students grasp content. Teachers value the support that visuals lend to classroom instruction because they encourage students to make associations between pieces of information, soak up chunks of course content quickly, and function as a memory aid.

But sometimes we teachers don’t approach the use of visual aids as carefully as we should. We may be too lax in monitoring how students interpret visuals (allowing the oversimplification of content) or how students create visuals (which shows whether they understand what should be included). As a result, students struggle to make the needed connection with course content.

As an educator who relies on graphic organizers and charts in the classroom, I have three strategies for using visual aids without sacrificing course content.

Sharing Intent

We often naively believe that a visual can stand on its own with minimal explanation. Instead, we should directly communicate to students what we hope for them to see (or interpret) based on the lesson at hand. For example, it’s useful to help students explore why the visual was selected and what the key characteristics of it are, and to identify the non-essential elements of it. And we should specify what we intend for the students to know after examining it. For instance, Professor Howard Cox’s purpose in integrating props like an officer’s cap and a replica revolver into his lectures on fiction set during the Civil War is to help build his students’ foundational knowledge about an author’s purpose and inspiration.

If time allows, I like to share a “runner-up” image and invite students to consider why the image didn’t make the cut. This discussion can deepen their understanding. And teachers can use prompts to help students reach that deeper understanding. Examples include “This image is a stronger representation of the concept because _____” and “This image makes me think about _____ from our lesson, which is important because _____.”

Activating Discussion

Most teachers encourage some level of class discourse when presenting a visual aid, but we need to go a step further. We can promote a conversation about how the visual helps in processing the course content. For example, ask students to share how the visual reinforces—or challenges—what they previously learned about relevant vocabulary terms. In my College Readiness class, we review a line graph that compares letter grades and attendance, discussing how the upward direction of the lines supports our expectations of a connection between consistent attendance and higher grades. We also question the story presented by the graph: Beyond lower grades, what consequences do absentee students face?

To increase students’ processing opportunities, use a think-aloud to get students talking about what makes a visual useful vs. the qualities that seem less important to understanding the theme or central message of the graphic or its connection to other content.

Push students to think deeper. For instance, in order to promote retrieval practice , put the visual away and ask students to break down the concepts represented in the visual relying solely on their memory. It’s important to discuss any discrepancies between what the students recall and what’s actually present in the image.

This is an excellent opportunity to explore misconceptions about the concept at hand. It’s also an ideal time to highlight any blind spots or typical areas of confusion related to the concept. For example, when sharing a bar graph, caution students that the measurement scale can lead them to misread it, especially if the y-axis starts with a random number instead of zero or if information is measured in the short term instead of the long term.

Creating Visual Aids as a Class

I believe involving students in the design of visual aids is essential to foster buy-in and learning ownership, but initially, students may hesitate to create their own visuals and take on the designer role.

Establishing design parameters for students should help. For example, limit their format options by specifying the type of graphic organizer or chart they can use, and provide time to discuss what kinds of visuals would potentially work best based on the content at hand. You can also assign a specified number of key concepts—based on the content reviewed—that students are required represented with their visual.

For students who continue to seem uncertain about creating a visual on their own, educator Matt Miller explains the value of maintaining a library of icons  (related to the topic, of course). Such a library allows students to focus on making meaning from the course material instead of becoming frustrated with the design work.

In addition to parameters, offer models. Make a point of asking students if it’s OK to share their visual with peers, and let them know why you wish to share their work. And teacher models are priceless. Dr. Deidra Gammill, a high school teacher in Mississippi, makes a habit of including images in her notes in order to provide concrete examples for her students to follow.

It’s not enough for a visual to capture attention—it should help students become more engaged. Over time, I’ve learned that aligning visual aids with course content is a deliberate process, one that is harder than I realized when I was starting out. With appropriate attention, we can ensure that our visual aids are windows to our lessons’ purpose and construction.

Types of Audio Visual Aids: Enhancing Communication and Learning

Types of Audio Visual Aids: Enhancing Communication and Learning – In today’s fast-paced world, effective communication and engaging learning experiences are crucial. One powerful tool that has revolutionized the way we share information and learn is audio-visual aids. These aids combine both auditory and visual elements to deliver information, making it easier to understand complex concepts and retain knowledge. In this article, we will explore various types of audio-visual aids that are widely used in education, presentations, and everyday communication.

Table of Contents

Audiovisual Aids

Audiovisual aids are instructional materials that use both audio and visual elements to convey information. They can be used in a variety of settings, including classrooms , businesses, and healthcare facilities.

Types of Audio Visual Aids

There are two main types of audio visual aids: audio aids and visual aids .

Audio aids are materials that are primarily auditory in nature. They include things like radio , tape recorders , CD players , and MP3 players . Audio aids can be used to play music, stories, and other audio recordings. They can also be used to provide instructions or to create a more immersive learning experience.

Visual aids

Visual aids are materials that are primarily visual in nature. They include things like charts , graphs , maps , pictures , models , and posters . Visual aids can be used to illustrate concepts, to provide information, or to create a more engaging learning experience.

Example of different types of audio visual aids

types of audio visual aids

Various types of audio visual aids

Audiovisual aids can be a very effective way to present information, as they can appeal to both the auditory and visual senses.In this article, we will explore various types of audio-visual aids that are widely used in education, presentations, and everyday communication.

1. The Power of Visuals

Incorporating visuals into communication can significantly enhance understanding and retention. Visual aids like images, diagrams, and charts make complex ideas more accessible and appealing to the audience. Studies have shown that information presented with relevant visuals is better remembered than plain text.

2. Exploring Images and Photographs

Images and photographs are potent tools to convey emotions and concepts that words alone may struggle to capture. In presentations and educational settings, using relevant images can evoke emotions, stimulate critical thinking , and create a lasting impact on the audience.

3. The Role of Videos

Videos have gained tremendous popularity as an audio-visual aid due to their ability to combine visuals, sound, and motion. They are particularly useful in educational settings, as they offer dynamic explanations and demonstrations of various subjects.

4. Infographics: Conveying Information Creatively

Infographics are graphic representations of data and information. They present complex statistics, processes, or comparisons in a visually appealing and easy-to-understand format. Infographics are widely shared on social media platforms due to their engaging nature.

5. Powerful Presentations with Slides

Slides, commonly used in presentations, are an effective way to organize content and maintain a flow during a speech. They allow presenters to break down complex topics into smaller, more manageable segments, keeping the audience focused and attentive.

6. Audio Aids: Making Listening Interactive

Audio aids encompass sound effects, music, and narration. They add depth to presentations and create a more immersive learning experience. Well-placed sound effects and background music can add emotion and context to the information being shared.

7. Interactive Whiteboards: Engaging Learners

Interactive whiteboards combine the features of traditional whiteboards with digital technology, allowing educators to create interactive lessons. Learners can actively participate, solving problems, and collaborating on the whiteboard.

8. Virtual Reality (VR) and Augmented Reality (AR)

VR and AR are cutting-edge audio-visual aids that provide a simulated experience to users. In education, they offer immersive learning opportunities, allowing students to explore historical sites, travel to outer space, or study complex scientific phenomena.

9. Using Props and Models

In various settings, physical props and models are employed to provide a tangible representation of abstract concepts. By using props, presenters can create a multisensory experience, enhancing comprehension and memorability.

10. Live Demonstrations and Performances

Live demonstrations and performances bring audio-visual aids to life. They are commonly used in training sessions, workshops, and artistic presentations, engaging the audience and leaving a lasting impression.

11. The Role of Interactive Multimedia

Interactive multimedia combines various media elements like text, audio, video, and animation. This dynamic approach to presenting information fosters active engagement and interactivity, making the learning experience more enjoyable.

12. Podcasts: Learning on the Go

Podcasts have gained immense popularity as portable audio-visual aids. They provide a flexible way to learn on the go, as users can listen to informative discussions and interviews on a wide range of topics.

13. Using Virtual Presenters

Virtual presenters, also known as virtual avatars, are computer-generated characters designed to deliver information in a human-like manner. They can enhance the accessibility of information and make learning experiences more enjoyable.

14. Gamification in Learning

Gamification incorporates game elements into non-game contexts, including education. By using audio-visual aids like game-based simulations, educators can create an engaging and motivating learning environment.

Audio-visual aids have become indispensable tools in modern communication and education. From enhancing presentations to revolutionizing learning experiences, these aids have the power to captivate, inform, and inspire audiences.
