Non-computer-based Interactive Lecture Demonstrations

Abstract

Interactive Lecture Demonstrations (ILDs) originally involve a microcomputer-based teaching technique that makes use of real-time measurements of simple experiments. However, computers and laboratory probes are more often not readily available in developing countries. This workshop exposes the participants to the possibility of extending the application of the well-defined procedure of ILD to simple, non-microcomputer-based activities. The advantages of applying ILD to simple activities are three-fold: (1) the materials used for the simple demonstrations are readily available and inexpensive; (2) the set-ups can be easily designed and fabricated in a general physics laboratory; (3) home-grown demonstrations can be made interactive and hence, can still be used to optimize student learning of physical concepts.
