An audiotutorial approach to problem-solving in college chemistry relying upon audio tapes is available. The program is designed to increase the teacher's effectiveness by providing individualized attention to student difficulties related to problem-solving. Problem solutions are recorded on audio tapes (designed for use with Sony TC-160 cassettes or Sony TC-630 reels) and accompanying notes presenting visual and written material are prepared. The following topics are covered: units and conversion factors, weights, equations and stoichiometry, reactions, solutions, gases, equilibrium, solubility product calculations, acids and bases, ionic solutions, energetics, thermodynamics, galvanic cells and electrodes, dynamics, kinetics, nuclear chemistry, and radioactivity. The individual units are arbitrarily arranged but within units there is an ascending order of problem complexity and the units are structured to teach chemistry rather than problem-solving per se. These units are not designed as a priori introductions to problem solutions; students are first expected to do required reading and attempt to solve problems on their own, using the tapes for review and for tutorial assistance on troublesome matters.
