Improved Access with Classroom Instructional Media Tools

Traditional classroom environments have included standard equipment such as chalk boards, overhead projectors, and TV/VCR combinations to aid instruction and learning. More and more teachers rely on a variety of newer media technology in the classroom, including laptops with DVD's and multi-media projection systems. In fact a recent survey by Philips Electronics indicates that more than 65% of teachers have access to projection systems that allow the entire class to view a video or computer program on a full wall screen. These media technologies provide greater flexibility for alternative teaching methods.

Several technologies are available to further enhance the use of existing media systems and increase access for all students by addressing their sensory, cognitive and physical abilities.

Displaying Information

Chalkboards have traditionally been used to display information. Overhead projectors can display transparencies with enlarged and colorful materials, making them easier to see for group activities. In recent years, other technologies have emerged:

GeoSafari Theater
For teachers using GeoSafari® Boards and overlays, you can project them onto a wall or screen for the entire classroom to see and interact with! Use the Theater unit on any standard overhead projector with special lesson card transparencies. This feature provides access to students by increasing the size of the question and answer fields.

Computers & Projection Systems hers

Whiteboards
Whiteboards have replaced chalkboards or been added as classroom equipment with colorful pens used to highlight and organize learning. Versions are available that, when connected to a computer, capture what is displayed to save, print or send by email. Webster Touch Sensitive Series (PolyVision)

SmartBoards (Smart Technologies)
The SMART Board is an affordable interactive whiteboard that works with a computer and a multi-media projection system to create a powerful tool for teaching, discussing and learning. With a computer image projected onto the Board, the surface becomes a touch screen to control any application. You can interrupt the application to highlight key information with a color electronic pen. Or use the Board as a chalkboard to list instructions, draw diagrams, offer notes, illustrate ideas and highlight important information. You can capture the information at any time, print it out, save it or email it to your students and colleagues.

Sound Amplification Systems

Better acoustics in classrooms benefit both teachers and children. "Background noise from loud ventilation systems, activity outside the classroom, and poor acoustics can lead to voice problems for teachers and create unhealthy learning environments. Technology and improved acoustics can help". (K. Anderson) In addition, many children have undiagnosed hearing problems especially children with other disabilities.

Sound Field Systems

Classrooms can be wired with Sound Field amplification systems for improved classroom acoustics. As the teacher speaks into a microphone, her voice is amplified to the entire class through speakers at several locations in the classroom. This system allows the teacher to be heard at equal volume in all areas of the room regardless of position. In addition, the speakers override the background noise for all of the students in the classroom. Students with and without disabilities are able to better perceive what is being said and stay focused longer with fewer distractions.

Portable Wireless Systems

Several wireless systems are also available for portable use by individual students.

TV/VCR

TV/VCR units are standard equipment in many classrooms. Have you noticed children straining to comprehend what is on the screen or paying little attention to the screen? Making sure all students have equal access to the information displayed on the screen can be enhanced through the following resources.

Captions
Videos and television programs display text written on the screen as words are spoken and sounds are made by decoding captions that are hidden in the video signal. They are similar to subtitles except with sound effects noted. Televisions made after 1993 include a decoder to allow captioning to appear on the screen. Videotapes must have captions placed on them prior to distribution. Look for CC or NCI markings on the tapes. Captions help many students to better understand what they are watching.
