Many forms of media can be used in math lesson plans placing the medium in the role of both instructor and as a tool used by the “live” instructor. This article touches on only a few but may give you some ideas for similar ways to do this in your classroom. One educator who developed and employed multimedia into math lessons found that:o mathematical vocabulary of the students increased (and they made a more conscious effort to USE the correct terminology)o students asked more questionso response quality improvedMath Lesson Plans – Medium as InstructorMedium: ComputerWhen teaching concepts or skills, the computer serves best in the role of tutor. There are many programs commercially available where the computer presents information and asks questions. Then, when the learner responds, the computer evaluates the response and determines what to present next. This is called Computer Aided Instruction (CAI) or Computer Based Training (CBT).In addition to tutorials, the computer can serve as instructor for drill and practice, simulations, and instructional games.Medium: VideoLong before computers entered the school environment, videos have been used for instruction. Traditionally, the video served the role of instructor while the “live” instructor simply reinforced the lesson presented in the video. Today, videos are being created that may be used as BOTH the instructor and a tool the instructor uses to teach related lessons (see below).Math Lesson Plans – Medium as ToolMedium: ComputerWhen carrying out definite functions, such as graphing, calculating, and storing/retrieving information, computers behave as a tool. Students can be engaged in activities that require collecting data, organizing it, and making graphs to show their findings. Because, in the business world, a graph is typically used to explain statistics, students should be encouraged to experiment with different graphic representations and pick the one that most “forcefully” displays the data.Medium: VideoHere are some ways that video can be used as both instructor and as a tool the “live” instructor uses to teach other concepts.o Modeling: Video on modeling behavior can be used to teach social skills but also as tool to explore the usefulness and applications of creating models in mathematics.o Scale: A murder mystery video can be used to teach problem solving skills and as a tool to demonstrate how scale is needed to construct a bar graph to prove the accusations against the culprit.o Monetary system: A social studies video on life in another country can be used as a tool to teach how monetary systems are based on a standard unit of value.These are just a few ideas. Creative instructors will continue to find interesting ways to use various mediums to teach math AND “relate” the concepts across disciplines.

JVC car stereo has always been for the car enthusiast like me. I have once been like you searching for the best car audio system before I bought my own JVC. With my personal research, I’ve learned that JVC offers a wide range of car entertainment products like Mpeg 4 in-car multimedia, MP3, DAB, WMA, in-car DVD, DivX, CD, Dolby DTS, pro-logic, and even steering wheel mounted control interface.When I bought my JVC car stereo, I never worried about installation issues. A professional audio installer for cars makes sure that your unit gets installed properly. What’s also nice about JVC’s design is that in-dash units are designed to fit most new cars.Reviews from other sites also indicate that JVC offers one of the latest in digital technologies when it comes to car audio systems. For example, JVC has the latest DSP advanced technology, which incorporates the most updated technologies in mobile audio systems. This gives you the most optimum listening experience while on the road.JVC car audios usually has the CC converter, which has three sections that has algorithms which can restore signals lost from the recorded digital signal from frequencies which are audible. These sections are for bit expansion, range expansion, and frequency conversion.As JVC goes digital in its car stereo technologies, you will find a wide array of features in every JVC car stereo that you purchase. For example, JVC’s USB/CD car audio with front AUX features a USB port in the front which can allow you to play songs from an iPod or iPhone or any USB device source.
