Describes a project that can be used to encourage intellectual independence in students and teach them some of the inquiry procedures used in scientific research. Discusses procedures, safety precautions, and sample results. (CW)

Outlines the genetic elements found in the bacterial cell which play a role in recombining DNA sequences. Provides a core structure to which the mechanisms occurring in and between bacterial cells can be related. Discusses the practicalities of recombinant DNA techniques. (Author/CW)

Describes a series of microcomputer-based laboratory exercises that are designed to assist undergraduate students in acquiring basic psychological concepts in memory retention. Mnemonics used in the exercises are explained, and computer-generated tabular and graphic displays designed for use in classroom demonstrations are described. (Author/LRW)

Describes simple, efficient techniques for treating hazardous chemicals so that nontoxic and nonhazardous residues are formed. Discusses general rules for management of waste chemicals from school laboratories and general techniques for the disposal of waste or surplus chemicals. Lists specific disposal reactions. (CW)

Deals with a fungus that plays an important role in the forests of Asia as a decomposer of recently dead trees and in agriculture as an important edible mushroom. Describes how to culture these mushrooms including materials, conditions, and troubleshooting. Gives ideas for classroom activities. (CW)

Details three demonstrations for use in chemistry classrooms. Includes: "A Demonstration of Corrosion by Differential Aeration"; "A Simple Demonstration of the Activation Energy Concept"; and "A Boiling Demonstration at Room Temperature." Each description includes equipment, materials, and methods. (CW)

Describes the "Grow Lab" program which is sponsored by the National Gardening Association. Discusses how eight square feet of classroom space are converted into a mini-ecosystem. Mentions the development of a curriculum guide to accompany the indoor garden. (TW)

Describes a data acquisition system developed for an undergraduate engineering students' instructional laboratory at Georgia Tech. Special emphasis is placed on the design of an A/D Converter Board used to measure the viscosity and temperature of motor oil. The Simons' BASIC Program Listing for the Commodore 64 microcomputer is appended. (LRW)

Reviews a book that presents a method for teaching writing supported by theory, and that is illustrated with examples of students' and teachers' writings. The authors' methods are based on four propositions drawn from their command of modern discourse theory, philosophy, and linguistics. (NKA)

Provides guidelines and practical advice for planning and running a computer lab for writing. (NKA)

Describes a technique which gives an automatic and accurate assessment of photosynthetic oxygen liberation with graphical results available immediately. This program takes readings from an oxygen electrode and a photocell simultaneously. The types of results and unique features of the technique are discussed. (ML)

Describes a three-week seminar for education students that simulated the environment of the classrooms in which they will eventually teach and focused on the writing process, the reading process, and the reading-writing relationship. (SRT)

Recounts the difficulties and rewards of designing and establishing a computer-based writing lab--including problems with planning, funding, staffing, and expansion of physical space. (NKA)

Defies the assumption that laboratory teaching skills are gained by preservice secondary science education majors through their undergraduate science programs, and presents expertise areas which every teacher should possess. Outlines activities for each skill which can become part of a methods course under the direction of science educators. (DH)

Describes the style of design of computer simulations developed by Computer Assisted Teaching Unit at Queen Mary College with reference to user interface, input and initialization, input data vetting, effective display screen use, graphical results presentation, and need for hard copy. Procedures and problems relating to academic involvement are…
