Talking with E.T.

An Authentic Problem-Based Learning Experience Based on Waves and Videoconferencing

Learning Strategies

Good teachers make it a point to vary their strategies so that all students are able to learn effectively in their classes.

Below is a list of some of the strategies used in this project to help students learn.

  1. Discovery - Students will use the TI-83 graphing calculators and the CBL (Calculator Based Lab) system with a microphone to record sounds, varying both the pitch and the loudness of the sound. Then they will synthesize a general rule that relates frequency to pitch and amplitude to loudness.
  2. Research - Students will use videos, books, and the Internet to discover basic SETI principles of communications.
  3. Standards Development - Students will collect sound and record their images to use as a known standard against which they can compare samples.
  4. Data Analysis - Students will analyze samples of instructor-prepared unknowns and use patterns to compare and classify data.
  5. Position Defense - Students will present data via net videoconferencing to an authentic audience, defending their position on potential extraterrestrial communications.
