AUDIO- VISUAL AIDS
Objectives List three common faults with audiovisual aids List five audio-visual aids and one advantage and disadvantage of each Prepare at least two overhead transparencies using the materials provided during a workshop
Objectives Demonstrate the correct use of at least three audio-visual aids. The use will be demonstrated during the trainee s formal fifty minute presentation during the final week of the course
Audio-Visual Aids - Definition Any device or piece of equipment that is used to help present information on a subject by stimulating a response May be a sight or sound device May be a combination of these
Audio-Visual Aids -Purpose Used to reinforce verbal communication
Audio-Visual Aid Uses Stimulate interest and emphasize Promote efficiency Clarify subject matter
Common Faults With Audio -Visual Aids Do not replace the instructor Illustrations are too crowded Colors are misused Letters and symbols are illegible
Sense Perception Sight is the most highly developed among the five senses The most effective verbal communication is enhanced through oral and visual messages 75% of our learning is through sight 13% of our learning is through hearing Students retain 50% of what they see and hear
Selection of Audio-Visual Aids Considerations Instructor experience Subject matter of presentation Size of room Composition of students Length of presentation Resources available
Determining Use of Visual Aids Write out your message Look for visuals Sketch the graphics Try the audio and visual combination
Types of Visual Aids
Chalkboard, Dry Write tm Board Simple Direct Inexpensive Versatile Uses symbols key phrases illustrations development of ideas
Chalkboard, Dry Write tm Board Advantages Easy to make changes Excellent two-way communication Inexpensive Good for step-by-step instruction
Chalkboard, Dry Write tm Board Disadvantages Not portable Not permanent Poor for showing details Time consuming Loss of eye contact with the class
Flip Chart Prepared on heavy duty paper or other flexible material Prepared prior to the presentation Vary in size 11 x 17 inches to 30 x 40 inches
Flip Chart Advantages Inexpensive Easy to prepare and make changes Easy to transport Simple to set up No special lighting Reusable Step by step instruction
Flip Chart Disadvantages Charts get dirty and ragged with use Attached art work may not roll up easily Tape-ons can fall off as they lose adhesive Class size limited to those who can see the chart clearly
Poster Prepared on heavy weight illustrative boards Allow for more sophistication Photographs and 3D objects can be attached
Poster Advantages Wide range of illustrative techniques can be used Permanent record Reusable Easy to set up
Poster Disadvantages Bulky Repeated use can cause poster to break or bend Less portable May warp Difficult to make changes
Photographic Slides Color slides A combination of photographic and illustrative techniques
Photographic Slides Advantages Subject matter is unlimited Can be easily rearranged Permanent and easy to handle and carry Projection equipment easily available Can be easily duplicated Presentation can be stopped for discussion
Photographic Slides Disadvantages Room needs to be dark Requires time and special equipment More expensive than flipcharts Requires set up time and testing Equipment may fail
Overhead Projector Produces an image indirectly by means of a mirror and a condensing lens Images are printed on transparencies Transparencies can be 10 x 10 in size
Overhead Projector Advantages Instructor can face the class and present information Easy to prepare and modify Can use step-by-step presentations Preparation is easy and inexpensive Handouts can be made directly from the transparency Permanent and reusable
Overhead Projector Disadvantages May require a darkened room Projection equipment may not be available Projection may change if not set up properly Difficult to manipulate
Audio Recordings Reel, cassette tape, compact discs Actual events can be played back to the class Excellent for training that requires repetition
Audio Recordings Advantages Easy to use and provide a permanent, reusable record Can record real episodes Recorders are portable
Audio Recordings Disadvantages Only provide the oral portion of an episode not the visual
Videotape Excellent to show reactions to behavior of a group or individual Instructor must be familiar with the operation of the equipment and the effective use of the videotape
Videotape Advantages Instant replay of subject material Permanent and reusable Versatile media Allows both the audio and visual to be recorded
Videotape Disadvantages Requires practice May be bulky to handle all the equipment May distract students while they are being vidoetaped
Models An actual replication of the object under discussion Usually made to scale Have movable and removable parts Excellent instructional aids
Models Advantages Having the real thing in the classroom Permanent and reusable Adds realism to training instruction
Models Disadvantages Expensive Can require skill to use in front of the classroom
Handouts Any written material to be covered in class or information that supports the material covered during class Can cover a lot of in depth material

Handouts Disadvantages Student will spend class time going over a handout if it is not covered in class Difficult to make changes if the handout is large Current forms need to be constantly updated Spelling must be checked
Demonstrations Show the trainee how the task is to be preformed Shows realism Excellent for learning skills Requires practice
Demonstrations Advantages Good for skills training Student will walk out with in depth knowledge of a task Allows interaction between instructor and trainee
Demonstrations Disadvantages Time consuming Low student to instructor ratio Instructor must perform well so trainee will perform well Needs extra equipment
Computer Presentations The use of a computer and a projector to show information Versions like PowerPoint tm and Corel Presentations tm Directly produces and image on the screen Good for showing graphics
Computer Presentations Advantages Instructor faces the class while presenting information Handouts can be made directly from the slides Permanent and reusable Animation and movement are possible Easy and inexpensive
Computer Presentations Disadvantages May require a darkened room Equipment may not be readily available Knowledge and skills are required to produce and perform
How to Use Computer Presentations Turn on computer and load PowerPoint tm Building a basic presentation Click on new slide Choose a slide layout Fill in text Save
How to Use Computer Presentations Adding a background Go to format and Apply design Pick a design already set up or create your own background by choosing a colot Animation Click on slide sorter view and pick the effect or transition wanted Save
How to Use Computer Presentations Inserting images Go to insert from toolbar Choose what file or clipart, this will automatically go into the slide Save Outline Choose outline from the toolbar Provides an outline format of the text for easier use
How to Use Computer Presentations Notes Go to View Notes Page on the toolbar This allows the user to make notes under the slide Printing Go to file and print Select handouts Print in color or black and white Slides can be used as handouts
Audio - Visual Tips Select the correct aid Prepare prior to instruction Be familiar with the equipment Know how to use the aid Make sure all students can see and hear the aid Check for effect on the class
Audio - Visual Tips Practice using different types of aids Do not get in to a rut Be flexible Experiment Select an audio visual aid that is appropriate for reaching the training objective
