A comparison of the effects of an investigative-based and a traditional laboratory program on students’ understanding of the process of science

PURPOSE OF THE STUDY The purpose of this study was to compare the effectiveness of two approaches to laboratory work in changing student understanding of the processes of science. An author-designed investigative-based laboratory approach was compared to a t r a d i t i o n a l laboratory method as outlined in conventional laboratory manual texts. This investigation was undertaken to provide empirical data concerning the effectiveness of an approach used in teaching laboratory work during the past fiv e years. The study was carried out in a senior high school in the B.C. Lower Mainland.
