Technologies in Education
Audio—addresses the needs of the auditory learner and adds dimension to instruction for all learners
Visual—content is articulated, clarified, and enhanced visually
Digital—continue to replace traditional audio/visual media
![Page 6: Lesson 7 Chapters 9 and 10 Audio, Visual, and Digital Technologies in Teaching.](https://reader035.fdocuments.net/reader035/viewer/2022062511/551c055e550346b24f8b4e45/html5/thumbnails/6.jpg)
Why use audio, visual, and digital technologies in teaching?
Engage more of the learners sensesBuild multiple cognitive connection to the
contentAddress the auditory or visual strengths
of many students
Give some examples of technologies you have seen used in college or school classrooms.

Listening vs Focused Listening
Listening—being able to hear and comprehend auditory stimuli
Hearing—the physical process of correctly receiving clear, audible sounds
Focused Listening—Giving one’s full attention to an auditory stimulus
What are some things teachers can do to ensure students are focused listening?

Traditional Audio Media
How would YOU use these technologies in your classroom?
Cassette tapesReinforce instruction/practice
Broadcast audioNational Public RadioNational Oceanic and Atmospheric Administration
(weather service broadcasts)
![Page 9: Lesson 7 Chapters 9 and 10 Audio, Visual, and Digital Technologies in Teaching.](https://reader035.fdocuments.net/reader035/viewer/2022062511/551c055e550346b24f8b4e45/html5/thumbnails/9.jpg)
Digital Audio Media
Optical Media CDs and DVDs
Internet Audio Download/store what you need rather than buying CD
Internet Radio Live and recorded programs from around world Can enhance language, social studies, science, etc. Can be broadcast for entire class, group, or individual
How would YOU use these technologies in your classroom?

Visual Technologies
Educators must select the most effective and appropriate visual technology for the content under study. Lever-Duffy, p. 294.
Types of Visuals Non-projected
Real objects, models, exhibits, printed materials, photos Projected
Overhead projector/transparency, digital projector, document camera

Elements of Effective Visual Design
Relevance Coherence Consistency
Proportion Contrast Unity and Direction
The same guidelines for creating effective transparencies are applicable to posters, flyers, slideshows, and/or other visuals.
Minimal text (7 lines by 7 words) Eliminate unnecessary detail Include simple graphics that add interest
![Page 12: Lesson 7 Chapters 9 and 10 Audio, Visual, and Digital Technologies in Teaching.](https://reader035.fdocuments.net/reader035/viewer/2022062511/551c055e550346b24f8b4e45/html5/thumbnails/12.jpg)
Multimedia in Teaching and Learning
Multimedia includes text, graphics, audio, and/or video
Video clip with sound
Simple clipart
Photograph

Traditional Video Technologies
Broadcast video Television (including instructional television)
Cablecast video Cable channels that offer instructional programming
Recorded video technologies VCRs and camcorders
Capture video images of field trips, your teaching, etc. Record special events, reports, debates, documentaries Create a video historical or cultural archive of the school or
community
![Page 14: Lesson 7 Chapters 9 and 10 Audio, Visual, and Digital Technologies in Teaching.](https://reader035.fdocuments.net/reader035/viewer/2022062511/551c055e550346b24f8b4e45/html5/thumbnails/14.jpg)
Digital Video Technologies
Captures and displays high quality sounds and images DVDs Digital video camera Compressed video systems
Bring live, fully interactive instruction from one location to the next
Distant guest speakers visit classrooms without travel Image and sound are as clear as broadcast vides Both locations must have appropriate equipment Particularly useful for distance learning
![Page 15: Lesson 7 Chapters 9 and 10 Audio, Visual, and Digital Technologies in Teaching.](https://reader035.fdocuments.net/reader035/viewer/2022062511/551c055e550346b24f8b4e45/html5/thumbnails/15.jpg)
Internet Video
Internet Broadcasts Live events and performances
Musicals, interviews, scientific or historic events Live Cams
A camera connected to a computer that is connected to the Internet
Internet Meetings Face to face meetings with people around the world Classes can meet in a single virtual classroom to share
ideas, experience instruction, and communicate
![Page 16: Lesson 7 Chapters 9 and 10 Audio, Visual, and Digital Technologies in Teaching.](https://reader035.fdocuments.net/reader035/viewer/2022062511/551c055e550346b24f8b4e45/html5/thumbnails/16.jpg)
Implementing Video in Instruction
Preplan Preview and evaluate video before presentation
Prepare the environment AND the students Make the video relevant to the students
Pre-post test Study guides Questions/discussion after video Note-taking requirements Inform students that test will include questions from
video Follow all copyright laws and fair use guidelines

REMEMBER . . .
The power of the Internet can put the world body of knowledge quite literally at one’s fingertips. A computer in a classroom can be an endlessly patient and positive tutor. An audio recording of a children’s story can encourage the development of good listening skills and meet the needs of auditory learners, and a nature video can bring the most remote corner of the world into the classroom.
