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…

Reaction workup can be a complex problem for those facing novel synthesis of difficult compounds for the first time. Workup problem solving by systematic thinking should be inculcated as mid-graduate-level is reached. A structured approach is proposed, building decision tree flowcharts to analyze challenges, and an exemplar flowchart is presented…

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…

A flow chart is used to illustrate analytical chemistry as a component of a problem-solving process. Beginning with a problem, the flow chart proceeds to the question, experimental design, experiments, data treatment, answer, and solution. Another flow chart is used to expand on experimental design.

Discusses the use of a small computer to solve self-consistent field problems of one-dimensional systems of two or more interacting particles in an elementary quantum mechanics course. Indicates that the calculation can serve as a useful introduction to the iterative technique. (CC)

Guidelines to use when solving complex design problems and two illustrative examples were presented in Volume 16 (No. 1), page 12 of this journal. Two additional examples are presented, focusing on ASCEND-II, a flowsheeting system to help "design" a computer model for a process. (SK)
