Microcomputer-based Interactive Lecture Demonstrations

Abstract

Interactive Lecture Demonstrations (ILDs) involve a microcomputer-based teaching technique that utilizes real-time measurements of simple experiments. Thus, the use of ILDs explores the use of real-time data to establish an active learning environment in the lecture portion of an introductory physics course. This workshop exposes the participants to the well-defined steps in conducting ILDs using state-of-the-art gadgets like sensors, probes, computer interfaces and microcomputers. Moreover, the workshop aims to present ILDs in a manner that the participants understand the activities and "trust" the apparatus and measurement devices used. The real-time display of data will give the participants feedback in a way that builds confidence in the measuring devices and the resulting data.
To show the applicability of ILDs to microcomputer-based experiments, various set-ups will be used to demonstrate concepts on static and kinetic friction, speed of sound, and magnetic field due to a current-carrying coil.
