The main purpose of this study was to describe the development and use of a flowchart for preservice chemistry teachers' problem solving on the First Law of Thermodynamics. Twenty-seven undergraduate preservice chemistry teachers attending a Physical Chemistry course participated in this study. The responses of the participants to the set of test…

The fields of mathematics, science, and engineering are replete with diagrams of many varieties. They range in nature from the Venn diagrams of symbolic logic to the Periodic Chart of the Elements; and from the fault trees of risk assessment to the flow charts used to describe laboratory procedures, industrial processes, and computer programs. All…

The University of Kansas experience in applying Total Quality Management methods illustrates how use of flow charts can reduce substantially the time spent on a complex data-collection and reporting process. Although flow chart construction can be time-consuming, it is a systematic way to uncover sensible solutions with significant payoffs. (MSE)
