Listening includes both hearing and comprehending audio

• Effective listening for learning includes

• Accurate hearing

• Focused listening

• Reinforcement to stimulate neural connections

Audio and Instruction






Audio Cassette• Economic, durable, and easy-to-use• Uses magnetic tape to record voice,

music, and other sounds• Can be used in centers, small groups, or

large group instruction May be used for many projects– Talking books, multimedia kits, oral

histories and journals are examples

Traditional Audio Media






Broadcast Audio• Received via radio or cable

audio channels

• Enhances content with current events, music, and foreign language

Traditional Audio Media






Optical Media (CD-ROMs)• Offer better clarity and

greater storage capacity than traditional audio media

• Easier to directly access target audio for replay

Digital Audio Media






Optical Media (CD-ROMs)• With CD-Rs and CD-RWs you can

also record audio• Advantages:

• Durable• Easy to handle• Portable• Variety of topics available

Digital Audio Media






Internet Audio• Instead of CD, you can download

legally available audio in WAV and MP3 compressed formats

• Need software media players (typically free) for play back

• MP3 is gaining popularity because its files are smaller

Digital Audio Media






MP3 Files• Visualizations sometime displayed

during audio playback

• MP3 players usually include recording and playback controls

• Typically music but may also include other audio elements

Digital Audio Media






Internet Radio• Using streaming media, radio stations

offer simultaneously broadcast via the Web as well as the airwaves

• National and international stations outside the local area are now available via the Web

• Includes music, news and talk stations from around the world

Digital Audio Media






Visual literacy • The ability to correctly interpret

visual signals• Visual experiences in education

designed to encourage visual literacy• Awareness of effective visual design

helps to impart visual literacy skills to students

Visual Communication






Visual Design Basics• Visual design includes visual, text, and

affective elements• Visual - graphics, symbols, real objects,

and organizational elements• Text - aspects of text including fonts,

spacing, color, and sizes• Affective elements - visual components

that can elicit responses from viewers








Can you See the difference?






Non-Projected Visuals• Real objects - objects brought into the

classroom as a visual enhancement

• Models - 3-D representations of real objects or concepts

• Exhibits - displays or dioramas created to illustrate instructional concepts







• Print Materials - commercial and teacher-made paper materials

• Graphics and Photos - pictorial images used to illustrate and clarify

• Support technologies include: Bulletin Boards, Flip Charts, Magnetic Boards, Chalk Boards, White Boards and Electronic White Boards







Technologies for Projected Visuals • Overhead Projectors shine light

through transparencies for large group projection of the images

• Transparencies can be, drawn, printed with ink jet or laser printers, or copied

Traditional Visual Media






• Commercial transparencies are frequently available with texts

• Transparencies can also be created with common software such as word processors or desktop publisher

• Be sure to select the right transparency film for your printer (laser or ink jet) to avoid damaging your printer







• Advantages

• Allows teacher to maintain eye contact

• Longevity of images

• Enable teacher to build concepts with overlays

• Easy to use and create







Digital Projectors • Used to project digital images from

computers, digital cameras, and photo CDs

• Allows for large group display of anything digital

• May also be able to display analog output from VCR

Non- Traditional Visual Media






Document Cameras• Video camera mounted on a stand

that captures and displays video images

• May use a monitor or digital projector for display

• Can zoom in on a real time demonstration or small objects

Non- Traditional Visual Media






Multimedia:• Combination of multiple visuals and

audio media into a single integrated whole

• Typically stored on a CD-ROM with hyperlinks between the elements

• Should be carefully evaluated for good design and appropriate and meaningful audio and visual elements
