Treating Chemical Equilibrium Mathematically in Secondary Schools: A Preliminary Investigation.
Case, James B.
This report presents the procedures, results, and conclusions of a study to determine the characteristics of secondary school chemistry students who were successful in grasping a mathematical approach to learning chemical equilibrium. Subjects were eighty-nine students enrolled in chemistry at a rural-suburban high school; each student had completed at least one-year of algebra and plane geometry. An experimental mathematically based unit on chemical equilibrium developed by the investigator was taught to the students. Six daily lesson tests and a final test were administered to the students during the study. Results indicated that about one student in five was successful in understanding the quantitative presentation of chemical equilibrium while the remaining students attained varying degrees of understanding of the experimental unit. The successful students were described as highly intelligent, with more than five semesters of mathematics and science respectively. Som e implications for teaching chemical equilibrium from a mathematically based approach are considered. (LC)
