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

The purpose of the study was to establish a list of acceptable terminal behavioral objectives for the nonmajor general biology laboratory as perceived by each instructor in every institution for higher education in the state of Missouri who is responsible for planning, organizing, operating, and evaluating that course. It was further the purpose…

Describes an experiment using an analog computer which allows students to work with familiar problems, and to program the computers themselves. (SL)

A laboratory study is detailed utilizing the skills of hypothesizing, designing experiments, and controlling variables. (EB)

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)
