Examination of Prospective Chemistry Teachers' Thoughts About Flow Diagram Usage in General Chemistry Laboratory

Abstract

The aim of the study is to examine the prospective chemistry teachers' views about performing the experiments with flow diagram in the context of general chemistry laboratory course. There were 19 prospective chemistry teachers. Two questionnaires were developed by the authors to obtain prospective chemistry teachers' views about the flow diagram usage in the general chemistry laboratory. The flow diagram instruction was fulfilled within six weeks. The first questionnaire was administered before laboratory instruction. The prospective chemistry teachers constructed four flow diagrams for four experiments and used them during laboratory instruction. At the end of the application, the second questionnaire was administered to investigate the effectiveness of the flow diagrams. It was found that most of the prospective chemistry teachers comprehended what the flow diagram was and how they were used in the laboratories. Besides, most of the prospective chemistry teachers stated that the flow diagrams were useful for time management and the preparation for the experiments.
