Recently, there has been a large amount of research in the area of self-access language learning (SALL) showing that students around the world react favorably to SALL (Gardner and Miller, 1997; McDonough and Shaw, 1993; Richtcrich and Chanceril, 1980; Sheerin 1989; 1991). There have even been a few reports showing positive results with students in…

Paper presented at the International Microteaching Symposium, Tubingen, West Germany, April 10-16, 1972. (DD)

Rationale, objectives, and instructional strategies for a directed study course on spectrophotometry are provided. Descriptions of three experiments and four student research projects are also provided. Objectives, laboratory procedures, advantages, and disadvantages for the experiments and projects are included. (JN)

A course combining aspects of traditional and self-instruction is described. Students' positive reactions exceeded expectation, and students favored the relaxed pace, practice exercises, and immediate instructor feedback. A disadvantage was faculty time required to provide feedback. (MSE)

Describes a software/hardware system for running computer-controlled physics experiments. Each set of experiments consists of a disk (for Apple 48K), instruction manual, and student manual. The pendulum and acceleration experiments are described. Although not described, experiments using a temperature probe are also available. (JN)

Presents procedures, demonstrations, activities, and teaching suggestions on topics appropriate for middle school science including a simple electrolysis cell, conversion factors, energy, solubilities of salts, condensers, and a worksheet for studying coppice woodlands. (DC)

Describes the Triad Model for cooperation among Upper Cumberland (a rural area in Appalachian foothills of middle Tennessee), College of Education (Tennessee Technological University), and State Department personnel. Discusses activities such as conferences, consultant-liason program, supervisory/administrative study council, field-based courses,…

Discusses determination of elliptical path of a satellite caught into orbit by the sun or earth; using microcomputer as signal generator (includes program listing); collision process; simple hysteresis loop using double beam CRO; method of demonstrating parallelogram of forces; measuring radius of electron beam curvature; and half-life of thorium…

Contends that the nature of physics has been misrepresented by blurring or ignoring important distinctions between "errors" and "discrepancies" and that dealing with these and related problems can improve students' enjoyment of labs and understanding of physics. Nature of physics, role of experiments, experimental errors, and error analysis are…

A Pittsburgh program to encourage physicians to choose clinical investigation careers consists of nine months of formal lectures and laboratory training and 15 months of a supervised laboratory research project. The curriculum ranges from basic laboratory techniques and biomedical content to advanced instrumentation, statistical analysis, computer…

Describes laboratory procedures, demonstrations, and classroom materials, including "diet poker" (nutrition game); an experiment on enzyme characteristics; demonstrations of yeast anaerobic respiration and color preference in Calliphora larvae; method to extract eugenol from clove oil to show antibiotic properties; and Benedict's test.…

Discusses dice model of exponential radionuclide decay; glancing and collinear perfectly elastic collisions; digital capacitance meter; use of top pan balance in physics; microcomputer calculation of gradient of straight line (includes complete Commodore PET computer program); Fresnel lenses; low-voltage radiant heater; Wheatssone's bridge used as…

Presents a discussion of the need to present a realistic view of the process of science to students in the laboratory. Several activities and readings are suggested. (SA)

A laboratory exercise using a gerbil is described for use in the high school biology class and in accordance with the National Science Teachers Association guidelines. The authors cite references that deal with current awareness of the moral status concerning animals. The exercise includes measurement and calculations. (SA)

Outlines procedures for constructing an instrument which uses an electrode and calibration methods to measure the salinity of waters in environments close to and affected by a saline estuary. (Author/DC)
