A learning library based on individualized instruction that technical teachers can put together is described. It requires not only teaching skills but a knowledge of systems engineering, graphic arts, TV programing, and other skills allied to TV and broadcasting. (Author/BP)

Describes how to construct a moving reference frame for the quantitative measurement of the Coriolis effect. (MLH)

Suggests and describes laboratory activities in which the Mexican axolotl (Ambystoma mexicanum Shaw) is used, including experiments in embryology and early development, growth and regeneration, neoteny and metamorphosis, genetics and coloration, anatomy and physiology, and behavior. Discusses care and maintenance of animals. (CS)

A brief historical account of the initiation and development of the Group Dynamics Laboratory Class at Indiana State University is presented, with the intent of helping other teachers evaluate their own laboratory offerings, or aiding the reader in initiating a similar course in his or her own institution. (MB)

Diagrams a quick, improvised cardboard circuitry for battery holder, bulb socket, and switches. Materials include corrugated cardboard, paper clips, and rubber bands. Assembly useful in determining the electrical conductivity of substances. (CS)

Describes an apparatus that can be used to prepare air-sensitive or water-sensitive samples for melting point determinations. (MLH)

Details life cycles and descriptions of the major aquatic insects. Instructions for collection and maintenance of live organisms are included. (CS)

Describes the construction and operation of a temperature programmer; it can be built for less than $100 and can be used with any gas chromatograph that uses a variable resistor to control oven temperature. (MLH)

Describes a study designed to explore systematically the practical advantages and problems of using videotapes in the undergraduate chemistry laboratory. (MLH)

Selected time components of the cardiac cycle were determined during breathing in air, breathing through a snorkel during face immersion, apnea in air, and apnea during face immersion. (PBS)

Presents guidelines for dealing with staff and the community, for setting up a "kick-off" learning center program, and for selecting a reading program. (Author/IRT)

Reviews research related to laboratory work and makes recommendations for the classroom on how to make labs more meaningful. Argues that pre- and post-laboratory discussions containing theory behind the lab and purposes of the lab are essential for new understanding. (DDR)

Describes a procedure used to measure force and pressure in elastic arteries. Discusses the physics of the procedure and recommends the use of bovine arteries. Explains the preparation of the arteries for the procedure. (DDR)

Describes an experimental project that uses plant tissue culture techniques to examine cell differentiation in the carrot. Allows students to gain experience in some important techniques and to explore fundamental questions about cell differentiation. (DDR)

Gives a step-by-step description of a problem-solving microscale chemistry laboratory to show how this implementation of problem-solving teaching can be put into practice. Pedagogical and practical issues are discussed. (DKM)
