The case for chemistry instruction based on worked examples is presented, using a contemporary model of human learning. We begin by detailing human cognitive architecture and outlining the Interactive Compensatory Model of Learning (ICML). Through the ICML, the role of motivation, deliberate practice and feedback are detailed as key variables in…

Describes an alternative method to algebraic procedures for solving problems involving the proportional composition of a mixture. (TS)

To help make the physics curriculum more relevant, twenty-nine "noncalculus physics problems are presented under nine problem types. With the support of the Commission on College Physics, the author solicited similar physics problems which will, after selection and editing, be made available to all physics teachers. (RR)

Presents responses to an earlier report concerning a procedure for the derivation of the Ideal Gas Law from Charles', Boyle's, and other gas laws. Logic errors and solutions that work are discussed. (CS)

Incorporates some ideas from a book by Galileo into a problem-solving format that challenges students. (LS)

Details are provided of computer-simulated experiments developed by the co-directors of the Learning Research and Development Center (LRDC), University of Pittsburgh. The initial materials were designed to help students learn physics. New materials are being developed along similar lines for elementary mathematics. The views of the creators are…

Describes a sequential problem solving method for teaching stoichiometry to high school students. Provides several sample problems. (CS)

Presents two examples of problem solving activities in which students are provided with helpful and extraneous information. Each of six group members must make verbal input for the collective solution of a problem. (CP)

A problem solving card program was constructed on the basis of Gagne's hierarchical sequence model to teach Unit II of the Physical Science Study Committee (PSSC) course in physics. The program was used to diagnose areas of difficulty in problem solving. Remediation on 52 identified mathematical abilities involved in the problem solving tasks was…

The purpose of this textbook is to provide junior high school students with the knowledge they will need to effect the changes that must be made for survival, to provide an environment that can sustain and flourish life, and understand and appreciate the aesthetic, social, and scientific implications of environmental problems. Organized around…

Considered are parallel and perpendicular relative velocities and their effect on the minimum time it takes a boat to cross a river. (Author/MA)

A survey of 167 chemistry professors was conducted to answer this question. Results pointed toward more concentration on mastery of basic concepts such as stoichiometry and problem solving while striving for greater relevancy to current societal problems. (CP)
