Resistance probes for the laboratory can be divided into two main categories: (1) those involving direct use of resistance; and (2) those involving an indirect use of resistance. Described are several applications of both types related to chemistry and physics. (RH)

Illustrates the conditions (facilities, support staff, and faculty training) necessary for developing the technology-based teaching of languages and the sophisticated use of computers and video and audio equipment, including the type of environment which provides access to materials and information and opportunities for testing, publication, and…

Described are three chemistry demonstrations designed to be used with overhead projectors. One activity suggests an activity for determining unknown liquids. The second activity describes a plastic spot plate for overhead demonstrations. Also described is a demonstration to show pH of selected chemicals. (RH)

Answers questions and presents user survey results regarding the applicability and effectiveness of the Tandberg IS-10 learning laboratory system for foreign language instruction. (CB)

Study looks at pigtailed macaque in the context of visual recognition problems adapted from a standardized test developed for use with human infants. Results demonstrate that the low-risk group easily differentiated novel from previously seen targets; the high-risk group gave no evidence of recognition. (Author/RWB)

Describes two complementary laboratory exercises that use the glass fiber assay to assess receptor specificity and hormone binding affinity in rat liver cytoplasmic extracts. Details the methods, materials and protocol of the experiments. Discusses the basic concepts illustrated and the feasibility of using the experiments at the undergraduate…

Describes an experiment to discover the topology of plasma membrane aminophospholipids (phosphatidylethanolamine and phosphatidylserine) using whole platelets and trinitrobenzene sulfonate (TNBS) as a probe. Reports changes in phospholipid distribution during platelet activation with simultaneous action of thrombia and collagen. Details the…

Describes generic problem-solving model constructed by D. Koberg and J. Bagnall that can be used by writing center tutors and that progresses as follows: (1) accept situation, (2) analyze, (3) define, (4) ideate, (5) select, (6) implement, (7) evaluate. Provides tutors with coherent framework and with way of breaking larger framework down into…

Twenty teachers were selected to teach 20 elementary classes a science lesson featuring laboratory experience in small groups. Ten teachers were alerted to the possibilities of sexism in the physical sciences. Results indicated girls in mixed-sex work groups participate less when the teacher is less aware of sexism problems. (Author/CH)

Describes a demonstration in which gaseous ammonia and hydrochloric acid are used to illustrate rates of diffusion (Graham's Law). Simple equipment needed for the demonstration include a long tube, rubber stoppes, and cotton. Two related demonstrations are also explained. (DH)
