Instructional Media and Technology for Learning Chapter Seven Audio Presented by Hongjin Wang
The Difference and Similarity Between Hearing and Listening • Hearing is a physiological process • Listening is a psychological process • Hearing is the foundation of listening • Hearing and Listening are also teaching and learning process
Developing Listening Skills • Guide listening • Give directions • Ask students to listen for main ideas, or inferences • Use context in listening • Analyze the structure of a presentation • Distinguish between relevant and irrelevant information
Audio Formats • cassette tapes • compact discs • Mp 3
The strengths and limitations of cassette tape The main advantages of audiotape • easy to record • easy to erase • easy to store • not easy to damage The limitation of audiotape • easy to record background noise • easy to become stuck and tangled • not easy to edite
The strength and limitation of compact disc Advantage of compact disc • very durable • High fidelity • No background noise • Random search Limitation of compact disc • Impractical to prepare locally • Initial expense of equipment
The advantages of audio • Inexpensive • Portable • Readily available and simple to use • Ease of lesson preparation • Reproducible • Ideal for teaching foreign language • Stimulating • Repeatable • Selections easy to locate • Resistance to damage • Provide verbal message for nonreaders
The limitations of audio • Fixed sequence • Doesn’t monitor attention • Difficulty in pacing • Potential for accidental erasure
Integrating Audio into classroom Teachers can use Audio Media in all phase of instruction – from introduction of a topic to evaluation of student learning. Students can use audiotape to prepare their class presentations and to learn foreign language
Producing Class Materials on Cassette Tapes • Need a blank audiotape, a tape recorder, a microphone • Prepare class materials to need to recorder Attention: • Maintain a constant distance from the microphone • Speak over the top of the microphone, not directly into it • If you make an error while recorder, stop the tape recorder, reverse it, and then continue recorder.
Checklist for Students/teachers-Prepared Audiocassettes • Minimize extraneous background noise • Maintain constant volume level • Ensure good voice quality and clarity • Express ideas clearly • Maintain conversational tone • Keep listeners involved • Coordinate with worksheet or study guide, if use • Express content clearly • Keep it short
Duplicating and Editing Audiotapes Three methods of duplication Audiotapes The acoustic method—dose not require any special equipment. just two recorder. The electronic method—can avoid unwanted noise from the environment The high-speed duplicator method– require a special machine
Selecting Audio Materials Before selecting audio materials, three more things to need to do are: • Analyzing audience • Stating objective • Ready to select, modify, design audio materials
Utilizing Audio Materials The five Ps for group use of audio materials • Preview the Materials • Prepare the Environment • Prepare the Learners • Provide the Learning Experience
Require Learner Participation Before you begin the lesson, determine how to get and keep students actively involved, One technique is to give students a set of questions to answer during the listening.
Evaluate and Revise Determine how effective the audio materials are: --Gather data by (1) making observations (2) evaluating test results (3) discussing experience with students --Then decide (1) to revise how you use the audio materials (2) to modify the audio materials themselves
