Audio and Motion Media

Audio Media

Audio - may be described as sound or music

Sound - meaningless noise or vibrations transmitted with frequencies ranging from 20 to 20,000 hertz

Music - the art of arranging successive sounds to form a unified and meaningful composition

Audio Media - an educational term which refers the use of elements such as voice, sound or music as instructional tools - they stand as instructional materials themselves or as auditory adjuncts

Studies on the Use of Audio Media

Kerr, 1999when accompanied by other forms of media, audio media may enhance the understanding of content material

Encyclopedia of Educational Technology, 2011in multimedia presentations, audio media elements provide emotion, drama and perspective and most importantly connect the learner to the presentation’s message

Serafini, 2004audiobooks have been found to improve children’s reading proficiency

Audio Media in the Classroom1. Audio Lessons

a. Multimedia - using more than one form of media such as text, graphics, animation and sound

b. Audiobooks - are narrated recordings of a book- used in schools by teachers of foreign language, physically challenged learners, and struggling readers or non-readers 

2. Songs and Rhymes - songs, rhymes, learning songs, music plays or teaching songs are used to help students remember important educational concepts

Audio Equipment/Tools

a. Audio Cassette Tape - a magnetic plastic tape that can be used as storage for analog audio recordings - have a lifespan of 10 to 15 years - cassette tape players and recorders are used to record audio and are used to play audio recordings in an audio tape

1. Audio Storage – refers to gadgets and materials that have the capacity of storing audio items over time.

b. CD/DVD/BDCompact Disc (CD) - are used to store digital audio recordings

- seen as an enhancement of phonographic records

- can store up to 700 megabytes (MB) of data

DVD - an optical disc storage technology for video, audio, and computer data

- can hold high-quality audio, pictures, and any other sort of digital information - can store up to 4.7 gigabytes (GB) of data

Blu-ray Disc or BD - allows recording, rewriting and playback of high-definition (HD) video, as well as storing large amounts of data

- five times the storage capacity of DVDs and can hold up to 25 GB on a single-layer disc and 50GB on a dual-layer disc

c. Flash and Computer Hard disk drivesFlash drive / USB drive - a small portable storage device that is connected to a computer via USB portHard Disk Drive - on any computer or as external hard disk drives

d. Mobile phones- are good audio storage, recording devices and players

e. Audio Players- plays audio files in formats such as .wav and mp3

2. Microphones and SpeakersMicrophones - transducers which detect sound signals and produce an electrical image of the sound that is delivered

Speakers - an electroacoustic transducer that uses a magnetic circuit to achieve acoustic radiation

3. Audio Editing Software - lets you record and edit music, voice and other audio recordings

1. Find the best recording distances and positions for the speaker in relation to the microphone (usually 6 to 18 inches directly in front of the mic).

2. Speak in a clear, distinct conversational manner.

3. Eliminate all undesired background noises.4. Do not move the microphone during recording

because of its sensitivity.5. Do your recording in a room without excessive

echo quality.6. Make a provision against interruption.

Tips for Audio Recording

1. Direct learning from the speaker2. Improve the listening skills of

the students3. Catches and enhances the

attention of the students4. Handy5. Can be played over and over

again6. Retrievable information7. Can serve as a verbal record for

interviews

Advantages of Audio media

1. Limited attention concentration2. One-way communication3. Requires good listening skills4. Basic method of teaching is repetition5. New materials necessitated extensive

use of equipment with all associated problems of black-out and worn out cassette tape

6. Equipment could break down7. Analog format is not sophisticated

equipment of today8. Hardware involved extra time, worry, and

problems

 

Limitations of Audio Media

Motion Media

- instructional media that employ moving images such as television, motion pictures, films and video recordings

- a widely used telecommunication medium for transmitting and receiving moving images

- may specifically refer to television set, television programs or television transmission

- used for viewing recorded material from video cassettes, laser discs, DVS discs and Blu-ray discs

- if it does not provide for tuning and broadcast signals, and its purpose is just a display device, then it is a monitor

Television

- a celluloid material on which a series of still images are chemically imprinted

- are made up of a series of individual images called frames

Film

- refers to several storage formats for moving eye pictures: digital video formats and analog videotapes- can be recorded and transmitted in various physical media: in magnetic tape when recorded as PAL or NTSC electric signals by video cameras, or in MPEG-4 or DV digital media when recorded by digital cameras

Video

1. 8mm Video format2. Beta Format3. DV Video4. DVD Video5. LaserDisc Video Format6. VHS Format7. Material eXchange Format (MXF)8. Moving Pictures Expert Group (MPEG)9. Flash Video Format10. Windows Media Video11. DivX12. H.26413. XVid

Video Formats

1. Manipulation of space (events in microcosm and macrocosm)

2. Alteration of time (slowing down, reversing, or stopping time)

3. Compression of time4. Expansion of time5. Animation6. Safe observation7. Skill observation and learning8. Dramatization9. Encourages affective learning10. Helps develop problem solving11. Helps develop cultural understanding

Advantages of Motion Media

1. Fixed pace2. May cause

misinterpretation3. Cost4. Logistics

Limitations of Motion Media

1. Conduct preview2. Prepare environment3. Prepare audience4. Present the material5. Require learner

participation6. Evaluate
