Discusses the concept of kinetic versus thermodynamic control of reactions. Explains on the undergraduate level (1) the role of kinetic and thermodynamic control in kinetic equations, (2) the influence of concentration and temperature upon the reaction, and (3) the application of factors one and two to synthetic chemistry. (MVL)

Presents an experimental approach to teaching molecular orbital models. Suggests utilizing photoelectron spectroscopy and molecular orbital theory as complementary approaches to teaching the qualitative concepts basic to molecular orbital theory. (SLH)

Force diagrams involving angular velocity, linear velocity, centripetal force, work, and kinetic energy are given with related equations of motion expressed in polar coordinates. The computer is used to solve differential equations, thus reducing the mathematical requirements of the students. An experiment is conducted using an air table to check…

Introduces a pictorial, intuitive approach that allows the teaching of thermodynamics equilibrium in an introductory college physics course. (GA)

A secondary school teacher presents his teaching methodology concerning the kinetic theory of gases and gas laws. (CP)

Investigates spontaneous reasoning of 709 French, Belgian, and British students in elementary dynamics using the relations between force, energy and motion as the study topic. Students were selected from the last year at secondary school to the third year at university. (HM)
