Provides a two hour experiment using direct gravimetric methods to determine solubility constants. Provides methodology and sample results. Discusses the effect of the common ion on the solubility constant. (MVL)

Compares the administrative structures and educational ideologies of the writing center model and the curriculum-based model of peer tutoring. Argues that while the curriculum-based model may be administratively more efficient, the writing center model offers a collaborative learning environment in which students critically understand themselves…

A 1986-1987 survey of the physiology curricula in U.S. medical schools revealed that physiology departments must give a high priority to reorganizing and revitalizing teaching. There is a need to reevaluate course content, decide the fate of the student laboratory, and develop new, innovative teaching techniques. (Author/MLW)

Discussion of the use of microcomputers in secondary schools in the United Kingdom focuses on classroom use versus separate computer laboratories. Group dynamics among students working at computers are discussed; teachers' attitudes are considered; single microcomputers versus computer networks are examined; and case studies from geography classes…

Reported are highlights of a workshop related to the geosciences sponsored by the National Science Foundation (NSF). Discussions include recommendations for the NSF's undergraduate education programs including support for individual students, laboratory activities, faculty enhancement, curriculum, courses, and underrepresented groups. Precollege…

Compares the relative effects of hands-on and teacher demonstration laboratory methods on declarative knowledge and procedural knowledge achievement. Reports that students in the hands-on class were better on the procedural knowledge test than students in the demonstration class. (Author/YP)

Describes an interface that uses semiconductor metal oxides to detect low gas concentrations. Notes the detector has long life, high stability, good reproducibility, low cost, and is able to convert the gas concentration to an electrical signal with a simple circuit. Theory, schematic, and applications are provided. (MVL)

Presents a demonstration that gives students an opportunity to observe how the composition of food can be analyzed. Outlines materials, directions, and background enrichment information. Cites additional references for use. (RT)
