The aim of this study is to develop an experimental presentation method to change high school students' naive concepts regarding the laws of physics into scientific ones. The apparatus used was designed and constructed to teach students the principles of inertia both visually and auditorily. The subjects were seventy high school students. They were randomly assigned to one of two treatment groups. The subjects in the experimental group (20boys and 23girls) were taught physics using the apparatus, while the subjects in the control group (15boys and 12girls) were taught by the traditional teaching method of lectureing. An achievement test on inertia and a questionnaire on scientific views were administered to them as pretest and posttest. It was found that the experimental group showed more improvement in both the achievement test and the questionnaire than the control group. How the subjects in the experimental group changed their naive concepts into some scientific concepts is also discussed.
