Audio-Visual Media in Education

• Enhancing learning with various forms of media includes audio-visuals and manipulatives.

Projected Media and Display Technologies

• Display surfaces facilitate viewing visuals in the classroom.
• Still images can be enlarged and shown on a screen via computer or other projected device.

Types of Display Surfaces

• Chalk board.
• Cork board.
• Flannel board or felt board.
• White board.
• Magnetic board.
• Flip chart.

Contemporary Projected Devices or Equipment

• Digital video disc player.
• Portable DVD player.
• Television.
• Digital camera.
• Document camera.
• Digital projector.

Learning With Audio-Visual Media

• Encompasses electronic media formats using "motion pictures" to present a message, including the element of sound as audio.
• Audio/Video.
• Educational television.
• Cablecast network programs.
• Film.

Audio/Video

• Generic term for audio and video components and capabilities in home entertainment, product descriptions, and reviews.
• It involves recorded pictures and sound, or the equipment that produces them.

Educational Television

• Involves television programs for distance education as individual broadcasts or dedicated channels.

Cablecast Network Programs

• Defined as "cable channel" (or "cablenetwork") via cable television, transmits directly to receivers via coaxial cable.

Film

• Also known as a movie, motion picture, theatrical film, or photo play, presents a series of still images that, when shown on a screen, create the illusion of motion.

Benefits of Using Educational Video in the Classroom

• Generates greater interest and enjoyment than traditional printed materials.
• Makes understanding diverse cultures easier.
• Challenges students to predict video presentation outcomes.
• Extends learning beyond the textbook.

Limitations of Using Educational Video in the Classroom

• Can cause students to lose focus.
• Movies may take up too much time.
• The educational portion of the movie may be small.

Multimedia

• Content that uses a combination of different forms such as text, audio, images, animations, video and interactive content.

Advantages of Using Multimedia

• Ability to incorporate images, sounds, and videos without leaving the classroom.
• Use of images with text reduces cognitive load and increases retention.
• Creates a professional presentation.

Disadvantages of Using Multimedia

• Students less proficient with technology might spend more time on computer skills than course content.
• Requires appropriate software and projecting tools, like projectors, laptops, screen, and audio equipment.

Using Manipulatives in the Classroom

• Manipulatives are physical teaching aids that engage students visually and physically with objects like coins, blocks, puzzles, and markers.
• These are teaching aids used to engage students in hands-on learning.

Principles for Maximizing the Effectiveness of Manipulatives

• Use a manipulative consistently over an extended period.
• Start with highly transparent concrete representatives and shift to more abstract representations over time.
• Avoid manipulatives that resemble objects or have distracting features.
• Explain the relation between the manipulatives and the concept explicitly.
