Suggests uses for and possible adaptations of a set of semiflexible molecular models. Includes price and supplier information. Also suggests rubbing oil from human face/hands along the pouring lip of a beaker, allowing one to pour uniformly from the beaker spout and making the process as dripless as possible. (Author/JN)

Reviews two textbooks: "Principles of Biochemistry" by Albert L. Lehninger and "Inorganic Chemistry, A Modern Introduction" by Therald Moeller. Also reviews text, study guide, and laboratory manual for Morris Hein's "Foundations of College Chemistry, Fifth Edition" and text/study guide for David A. Ucko's "Basics for Chemistry." (JN)

A nontraditional laboratory course for first-year medical students is described, consisting of two laboratory exercises adapted to the guided design strategy and a short research project. Student learning and attitudes were shown to improve, but curriculum preparation time was a major disadvantage. (MSE)

Outlines procedures demonstrating that the aperture of a microscope objective limits resolving power and then, by using ancillary measurements made with a calibrated graticule in the microscope eyepiece, that the experimentally determined value for the maximum resolving power of a given objective is close to the value predicted by theory. (JN)

Analysis of the literature of second language learning as applied to language laboratory use suggests that the emphasis be placed on listening comprehension prior to and independent of productive oral use of the target language, both to establish comprehension and to sustain student motivation. (MSE)

An early field experience program is described which attempts to convey the connections between theoretical knowledge and practice to preservice elementary school teachers. The program is guided by John Dewey's concepts of apprenticeship and partnership. Preservice teachers are encouraged to look on their own teaching reflectively. (PP)

Dental instructors are encouraged to use questioning techniques more frequently in clinical and preclinical courses, to stimulate independent thinking. The characteristics of questioning, types of questions, reluctance to use the techniques, strategies with various student types, and strategies for awkward situations are discussed. (MSE)

Describes use of Tinker Toys in several moment of inertia laboratory experiments at the advanced high school or introductory college levels. Includes procedures to be followed, arrangements of the Tinker Toy parts during experiments, and typical student data obtained. (JM)

The Physical Education Teaching Laboratory, at the Universities of Calgary and British Columbia, addresses beginning teachers' problems in applying basic motor skill acquisition and instructional design concepts to teaching and learning. Various components of the laboratory are described. (CJ)

In a study of the reliability of evaluation of laboratory techniques by recent dental graduates versus faculty, wide variance was found in student evaluations. However, faculty evaluations were consistent with each other only 40 percent of the time. Questions are raised about the general system of preclinical evaluation. (MSE)

Describes an experiment simulating a real-life structure elucidation problem through isolation, characterization, and chemical transformation of an "unknown," naturally occurring monoterpene, with extensive use being made of spectroscopy and aided by biogenetic considerations. Information given to students, procedures, results, and discussion of…

Discusses experiments involving classical conditioning of planarians. Suitable for advanced high school students or college-level independent study, flatworms are trained to curl up under a bright light. Then the planarians to are subjected to controlled reproduction experiments to determine whether the learned behavior is inherited by their…

Describes principle imaging techniques, their applications, and their limitations in terms of diagnostic capability and possible adverse biological effects. Techniques include film radiography, computed tomography, nuclear medicine, positron emission tomography (PET), ultrasonography, nuclear magnetic resonance, and digital radiography. PET has…

Reports 1978/1979 survey results which determined degree of importance Malaysian schools (n=90) and science teachers placed on laboratory safety. Results of 40-item questionnaire (included in an appendix) focusing on laboratory rules, safety precautions, equipment storage, and teacher attitudes, indicate high concern for safety, continuing…

Describes the processes involved in clinical urinalysis and relates them to possible high school biology classroom uses. (CS)
