Abstract

Understanding the relationship between sound, light, and electricity can be a very challenging topic for pre-service students in a physical science class at the undergraduate level. Traditional lecture materials usually present this material as discrete topics. For this reason concept maps were used to develop an instructional unit on wave energy. Hands-on lab activities, and interactive computer simulations additionally supplemented instruction for each section of the unit. The effects of the use of concept maps were determined by a pre-post-test design. In addition to fill-in-the blank concept maps, students were asked to create group and individual concept maps, which were used to track their understanding of these concepts. The way this knowledge was applied largely depended on the students’ understanding of electromagnetism. In particular it was observed that the participating pre-service students demonstrated capacity for distinguishing between the different conceptions of application of wave energy. Only students with a developed capacity for distinguishing between models were able to reason in a logical manner. They recognized the limits of models and were not only able to specifically designate changes from models and levels of models, but also to apply these in an accurate manner.
