Lesson Plan : Digital Audio
Teacher Name: | Jim Tavegia |
Grade: | Grade 7-8 |
Subject: | Math |
Topic: | show the importance of math skills as they not relate to the world of music reproduction |
Content: | Understanding the relationship between high level mathematics and audio reproduction. Key words: bit rate; sample rate, waveform; Reimann Sum; clocking; low and high frequencies, resolution, the physical medium of cds and DVDs, pits and lands of a CD/DVD, recording devices, recording software. |
Goals: | Students will understand that high level mathematics and sciences is being used to allow them to enjoy the MP3 players and cd players they use to enjoy their favorite music every day. It is also allowing the to watch high definition television and to use their cell phones for a wide variety of activities. |
Objectives: | Allow the students to gain more respect for why we learn high level mathematics and how advances in applied mathematics and science allow us to enjoy our leisure time to a greater degree. These same advances allow us to bring new, exciting techonologies into the classroom to make learning more enjoyable (smartboards). |
Materials: | Laptop with MicroSoft Power Point. High quality stereo system to allow for music playback. turntable for player LP records. A cassette deck for playing cassette tapes. Magnet with some iron shavings for explaining magnetism. |
Introduction: | To show how binary code, 1s and 0s, is allowing us to enjoy the highest fidelity music reproduction ever. This study will also show that the binary code can create hugh sound files of incredible high quality, or of a smaller file size (mp3) for portable use. Allow the students to hear the difference between high bit rate samples and low mp3 quality. |
Development: | The students will visuall see what wave forms look like on an oscilloscope, what wave forms look like in a digital audio recording program, will understand the frequency ranges that individual instruments can produce, and using microphones, what it takes to capture live music. |
Practice: | Students will be allowed to bring in their own music on a cd and then I will convert it into various file format sizes for them to try and recognize. |
Accommodations: | None |
Checking For Understanding: | Repeat the Independent Practice and see if the student's accuracy of choosing sound samples improves. |
Closure: | Ti instill a sense that there is a reason for them learning high level math and that the new, yet undiscovered, sound recording and listening devices will be invented by members of their generation who take mathematics applications to new levels. |
Evaluation: | progress will be measured by the reactions of the students who understand and appreciate how math is now used in music that they enjoy everyday, how it is created, how that music is transferred from the pits and lands of a rotating CD into binary code for them to enjoy without a thought. |
