Describes meta-analysis, a quantitative approach to conducting literature reviews. Illustrates the power of this technique by reporting the quantitative effects of cooperative learning on chemistry achievement in high school and college classes. (Contains 32 references.) (WRM)

Describes implementation of the "process workshop" model for university chemistry classroom instruction. Defines process workshop as a classroom environment where students are actively engaged in learning a discipline and developing essential skills by working in self-managed teams on activities that involve guided discovery, critical thinking,…

Describes various aspects of the composition, production, historical, and current use of glass in human society. Gives print and Internet references for further information. (WRM)

Illustrates that, contrary to some assertions made in the popular press, scientific literature, and introductory textbooks, glass does not flow in historic time. Contends that glass is a rigid solid with a lower degree of molecular order than a crystal but with greater molecular order than a liquid. (Contains 27 references.) (WRM)

Describes a chemistry-football analogy that likens an acid to a quarterback, and a base to a wide receiver. (WRM)

Describes a physical system for demonstrating operators, eigenvalues, and superposition of states for a set of unusual wave functions. Uses candy to provide students with a visual and concrete picture of a superposition of states rather than an abstract plot of several overlaid mathematical states. (WRM)

Describes a set of simple, inexpensive, classical demonstrations of nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI) principles that illustrate the resonance condition associated with magnetic dipoles and the dependence of the resonance frequency on environment. (WRM)

Explains why it is important for chemistry educators to know about metacognition, provides some examples to illustrate main points, and discusses some instructional tools that have been employed to promote metacognition in introductory science courses. (Contains over 50 references.) (WRM)

Information concerning structural chemistry and phase equilibria contained in the full phase diagrams of common substances is a great deal richer than the general chemistry students are given to believe. Discusses ways of enriching the traditional presentation of phase diagrams in general chemistry courses. (Contains over 20 references.) (WRM)

Presents a homemade, safe, effective, and inexpensive reactor vessel for ultrasonic horns with applications in microscale experiments in teaching and research laboratories. The reactor vessel is designed for an ultrasonic probe that allows reactions to be run at the microscale level at a wide range of temperatures and under inert atmosphere.…

Examines possible general chemistry topics that would be most relevant and practical for engineering majors. Consults the Accreditation Board for Engineering and Technology (ABET), engineering textbooks, texts from other required subjects, and practicing engineers for recommendations. (Contains 24 references.) (WRM)

Presents an activity that allows students to remove tarnish from silver using the reaction of tarnish with aluminum rather than the abrasion method of commercial tarnish removers. Makes suggestions for adapting the activity to an at-home investigation. (WRM)

Describes a study that used the ordered-tree technique to investigate knowledge change across the first semester of a college course in organic chemistry. Finds that over the course of the semester, students' knowledge trees became more similar to those of their professors. Discusses possible assessment uses for the ordered-tree technique.…

Presents a series of experiments that can be used to demonstrate how aspirin can be synthesized and characterized, how the hydrolysis of aspirin can be used as an introduction to kinetics, and how coordination chemistry (chelation) can be introduced by preparing and characterizing the copper complexes of aspirin and salicylic acid. (Contains over…

Presents an annotated bibliography of information useful for teaching, learning, and researching in chemistry. Entries are organized under the headings: (1) Continuing Sources of Assistance in Using and Teaching Chemical Information; (2) Guides, Sourcebooks, Proceedings; (3) Guides--Specific Subject Areas; (4) Guides--Specific Information Sources;…
