AUDIO IN TEACHING AND LEARNING

With a microphone or an MP3 recorder teachers can create a range of teaching audio resources that include lectures, topic summaries, assignments, and interviews with industry experts and other teachers. In the hands of students these tools provide an opportunity to practice and improve writing and verbal communication skills as they develop scripts for and record interviews, discussions, project summaries, product reviews, etc. These teacher and student resources when embedded in blogs and wikis provide “anytime - anywhere” access and enable collaboration and sharing of comments.

Audio can be used in versatile and imaginative ways in the design and development of teaching resources. As audio presents the spoken word, it enables information to be presented directly to an audience, even if it is only one way communication. Audio can also be used to supplement other media such as text, photographs, and graphics.

Advantages of Using Audio for Teaching Resources
Audio has the following advantages:
• provides a human touch.
• is relatively quick to produce.
• a large quantity of additional information can be included in audio segments, such as a more detailed explanation and a direct emphasis to important points.
• can provide the instructions or a description that guides product/service users.
• assists understanding of written material;
• adds variety to concepts.
• for users who have difficulty with reading audio provides an alternative to relying on reading ability alone.
