Describes the pattern of curricular shift in science education and the development of science, technology, and society (STS) curricula including two university cases. Outlines further development of secondary schools and the implications involved in implementing them. (Author/YP)

Described are the basic materials and procedures used to study defensive burying behavior and suggested laboratory projects. Discusses live targets, non-living targets, social variables, and previous experiences of the subjects. (CW)

Describes three criteria for evaluating educational software; classification of software types, the presence or absence of process skills, and educational practices. This article provides background for a software evaluation form to appear in a subsequent issue. (CW)

Describes the state-of-the-art in computer interfacing in the biology laboratory. Discusses hardware and software. Enumerates the educational benefits from instrumentation such as cost effectiveness and increased student opportunity and motivation. Includes 14 references. (CW)

Examines reading comprehension as it applies to the chemistry lab and describes techniques that promote better comprehension of lab materials. Lists four levels of reading to understand: literal, inferential, evaluative, and creative. Notes three methods to teach reading: the reference approach, mapping, and request. (MVL)

Presents an easily performed experiment to determine sucrose concentrations using a laser and a hollow glass prism. The experiment is suggested for high school, freshman college, and instrumental analysis classes. Notes an Erlenmeyer flask can be used instead of a prism. (MVL)

Presents a procedure for an integrated first year chemistry laboratory class which provides an effective and colorful procedure to develop manipulative skills in synthesis and purification. Uses thin layer chromatography and NMR spectroscopy in the determination. Provides Rf values and representative NMR spectra. (MVL)

Develops an experiment that could be done in two- to three-hour blocks and does not rely on cold room procedures for most of the purification. Describes the materials, methods, and results of the purification of bovine heart lactate dehydrogenase using ammonium sulfate fractionation, dialysis, and separation using affinity chromatography and…

Discussed are the potential hazards associated with nitric acid, inorganic and organic nitrate salts, alkyl nitrates, acyl nitrates, aliphatic nitro compounds, aromatic nitro compounds, and nitration reactions. (CW)

Discussed is the thermodynamic instability of organic peroxides. The process of autoxidation which results in peroxide formation is described. Precautions necessary to prevent autoxidation hazards associated with these reagents are suggested. (CW)

Reviewed is a computer software package for IBM personal computers. The theoretical background and functions including several examples are discussed. The algorithm used in computation by the program is given. (CW)

Examines the correlation between doctoral degree productivity and extramural research funding. Discusses how to use the results. Presents examples of how administrators use the correlations for analysis and planning of their programs. (YP)

Discusses the emerging relationship between the National Science Teachers Association and the National Council for the Accreditation of Teacher Education. Describes the accreditation process and the nature of the standards. Presents some problems and reactions to them. (YP)

Presented is a policy regarding vivisection, dissection, and other use of animals in biology classrooms. Alternative teaching techniques are stressed. The organizational responsibility regarding this issue is discussed. (CW)

The Individualized Eclectic Examination is described. The format, design, and philosophy of the examination that emphasizes problem solving are discussed. Sample questions, student projects, and an illustration of the implementation of the exam are included. (CW)
