Lesson 3 of Media in Math
"Digital audio is technology that can be used to record, store, generate, manipulate, and reproduce sound using audio signals encoded in digital form" 
Audio is probably the hardest to incorporate into a mathematics lesson of all three. Yet throughout this lesson, hopefully you will gain some greater insight as to how this can be done.
Audio can be used in mathematics by:
- Students can record their own problems to share with other students
- Play just the sound to a math related video
- www.voicethread.com can be used for teachers and students to record their voice over an image. Since video includes a moving picture, this example is perfect to incorporate audio
- Having students listen to a recording of a word problem
→ A lot of times students jump ahead and start working with the numbers within the problem without actually reading the problem or knowing what exactly the question is asking. Having them listen to the problem first allows for the extra time to process the question, understand what is being asked, then proceeding from there. From here, the problem may be showed to the class in words, in case they would like to go back and read.
More About Using Audio:
- Today's apps and internet allow direct access to audio files rather than downloading mp3 files onto portable players .
- Freeverse (Macs), Sound Recorder (Windows), Black Diamond Sound Systems, Goldwave Inc., Cakewalk and Kazi Software are all software that allows audio to be recorded. From special effects, to digitizing vinyl records, you can find it here .
- The great thing about audio is that you can make it available for students all at once during class, or individually through each student's playback device. Depending on the lesson, you may want to choose one over the other .
- Podcasts can be used in which the student can subscribe to it and be notified of new recordings .
- Keep in mind that when uploading audio, it should be easily accessible for each student. Students should have no trouble finding and downloading the recording .
- Allows students to realize the importance of paying attention to the whole problem since some information in word problems are irrelevant.
- Good for audio learners. Many times, audio learners do not get to experience the way they like to learn other than listening to the teacher lecture. This offers a great change of pace to reach to these students.
- Often times students are overwhelmed by word problems and are either discourages, or go too fast just to get it done and over with. By paying attention to key ideas, students start to develop a plan in their head of the steps they need to take to solve the problem. In order to help students with this issue, listening to the problem may help.
-Students learn to take their time and may even realize that word problems really aren't that bad!

- What did I learn about audio?
- How can these ideas apply to a math classroom?
- Is there anything else I need to know to incorporate audio in math? Where can I find this?
Under the discussion tab, please do the following:
- Find a way that audio can be incorporated to a math concept
- Provide a brief explanation as to why you chose this particular audio piece and how it enhances the lesson (about 100 words)
- In about 100-200 words, discuss audio in math. You may include, but are not limited to:
- What you learned about using audio in a math class
- How audio can enhance learning
- How you plan on using audio in your own lessons
- Your thoughts on teaching math through the use of audio
