The document discusses different types of audio visual technologies used in schools. It describes broadcast, narrowcast, and cablecast video technologies as well as recorded video tapes. It defines visual literacy as the ability to accurately interpret visuals needed to function in society, and explains that it is learned through teaching and learning experiences. The document outlines different types of non-projected media like real objects, models, and print materials that can be brought into the classroom. It also discusses projected visuals such as overhead projectors, digital projectors, and document cameras. In closing, it notes how recorded video, non-projected media, and projected media could be implemented in the classroom.

1. Audio Visual TechnologiesBy Julie Alvarez

2. Types of video found in school:Broadcast Video – Commonly known as television.Narrowcast Video – Video’s targeted at smaller groups like schools.Cablecast Video– Video that is transmitted by a cable company with a coaxial cable to remote locations.Recorded Video Technologies - Tapes like VCRs

3. Visual LiteracyIs a type of literacy that enables the viewer to accurately interpret the visuals necessary for functioning effectively in our society.How is it learned? Through the many teaching and learning processes you have experienced.Why is it important? It allows someone to accurately interpret the visuals necessary for functioning effectively in our society.

4. Types of Media

5. Non projected media:Real Objects – An object that can be brought into the classroom safely. This is useful for classrooms because learners can examine and explore the object.

6. Non projected media:Models – Three dimensional representations of concepts or real objects that can not be reasonably brought into the classroom. This is useful because models can bring kinesthetic versions of concepts into the learning environment and can be manipulated and handled.

7. Non projected media:Print Materials – Visual displays that remain a centerpiece in most learning spaces. These are helpful because they orient visuals for the learner.

8. Non projected media:Graphics and photographs – drawings or cartoons are useful in the classroom because they can represent and clarify concepts and relationships.

9. Projected visuals:Overhead projectors –Visuals that are created on thin sheets of clear acetate that can be written on with dry erase markers.

10. Projected visuals:Digital projectors – Attached to a computer and displays software or internet activities.

11. Projected visuals:Document camera – a mounted camera that captures and projects an image of the table and shows real time images.

12. Implemented in the classroom:Recorded video technologies will be used in the classroom. We could show television shows like Bill Nye the Science Guy.Non projected media could be hung on the wall or placed around the classroom.Projected media will be used to show the process of doing a math problem or show the process of a concept.
