Students need to reflect on the practice of science to fully understand the nature of science (NOS), which is an important component of scientific literacy. In this paper, the authors describe how to implement an explicit and reflective pedagogy in college science laboratories and share examples from their implementation in a multiple-section…

This second report from the Analytical Chemistry Subcommittee presents ideas for using real-life samples for student analysis and for introducing the topic of developing procedures for analysis. (DT)

Describes an advanced analytical chemistry laboratory experiment developed for the determination of the performance parameters of a spectrophotometer. Among the parameters are the baseline linearity with wavelength, wavelength accuracy and respectability, stray light, noise level and pen response time. (HM)

A physics program within which students design their own experiments and construct the needed equipment is described. Different projects and equipment designed and built by the students are detailed as examples of the success of this program. (JP)

Presents a high school chemistry lab experiment using tin (II) chloride to explore the concepts of hydrolysis, Le Chatelier's principle, and electrolysis. Presents methodology and the chemistry involved. Offers questions for the students. (MVL)

Demonstrates a variety of electrical phenomena to help explain atomic structure. Topics include: establishing electrical properties, electrochemistry, and electrostatic charges. Recommends demonstration equipment needed and an explanation of each. (MVL)

Uses paper chromatography with food dyes to provide a simple and inexpensive basis for teaching chromatography. Provides experimental methodology and tabled results. Includes a solvent system comparison (Rf) for seven dyes and twenty-two solvents. (MVL)

Examined is the use of the microcomputer as a tutor, for simulations of experiments, and to provide graphic interpretations of abstract concepts in the college biology setting. Discussed are computer enhanced courses being used, the software library, and the computer laboratory facility. Lists reasons for adoption of computer enhanced format. (MVL)

Inadequacies of the traditional curriculum involving laboratory exercises are reviewed; general features of an integrated laboratory program are described. (DT)

A new approach to a research-oriented general chemistry laboratory is described. Objectives for the laboratory program are specified, details are provided concerning the program design, and the results of an experiment to evaluate the program are reported. (DT)

Describes the difficulties that arise from teaching science to mixed ability groups where individualized instruction is emphasized. (BR)

Presents a biochemistry experiment for college students that illustrates the purification of an enzyme. (HM)

This document presents a series of physics experiments which allow students to determine the value of unknown electrical capacitors. The exercises include both parallel and series connected capacitors. (SL)
