The kinetic parameters for the conversion of alpha-D-glucose to beta-D-glucose were measured using a blood glucometer. The reaction order, rate constant, and Arrhenius activation energy are reported for the noncatalyzed reaction and turnover number and Michaelis constant are reported for the reaction catalyzed by porcine kidney mutarotase. The…

Students need to reflect on the practice of science to fully understand the nature of science (NOS), which is an important component of scientific literacy. In this paper, the authors describe how to implement an explicit and reflective pedagogy in college science laboratories and share examples from their implementation in a multiple-section…

Attempts to delineate certain basic principles and applications of bioinorganic chemistry to oxidation-reduction reactions. Examines why zinc(II) is so uniquely suited to enzymated reactions of the acid-base type. Suggests the answer may be in the natural abundance and the basic physicochemical properties of zinc(II). (MVL)

Discusses five strategies to use in creating an environment that will foster the development of critical thinking. To make thinking the subject of instruction; focusing on the key aspects of higher-order thinking; providing opportunities for continual, explicit practice; questioning and developing an investigative nature; and reinforcing the…

Discusses the use of self-directed learning in a large group class. Describes a workshop for developing group communication skills. (YP)

This publication is the final report of the activities performed in the development of an introductory astronomy course operated in a competency based mode. The objective was for the course to be completely opposite from one which emphasizes memorization of factual knowledge. Instead, the student was to be involved in activities where he or she…

The report covers the activities of the Indian Science Improvement Project during the calendar year 1970. The major emphasis is on curriculum development activities. Topics covered include elementary and secondary school science programs, traveling science workshop, college science improvement program, special college/university program, technical…

The PLATO IV system of computer-based education developed at the University of Illinois is discussed. A brief description of the PLATO system operation is given, and lesson examples are provided for the areas of biology, geometry, chemistry, and physics. Basic problems in the field of computer-based education are discussed, along with possible…

Suggests methods for achieving creativity, including divergent and convergent thinking, in engineering education. Discusses creativity exercises, creating an atmosphere hospitable to creativity, and identifying the creatively gifted. (YP)

Described is a course development project in progress at Iowa State University, Ames, Iowa, that attempts to meet the individual needs and improve the attitudes of students in a large freshman biology course. Proposed is the implementation of the Phase Achievement System which involves the development of multi-concept level video-cassette lectures…

Identifies the properties and characteristics of supercritical fluids. Discusses the methodology for supercritical fluid chromatography including flow rate, plate height, column efficiency, viscosity, and other factors. Reviews instruments, column types, and elution conditions. Lists supercritical fluid data for 22 compounds, mostly organic. (MVL)

This review for 1976 has been issued to analyze and synthesize research related to the teaching and learning of science completed during the year. The review is intended to provide research information for development personnel, ideas for future research, and an indication of trends in research in science education. Research has been listed in…

Lists questions that can be used to help students learn how to write letters of inquiry. States that as a result, students begin to feel less like students and more like professionals. (RT)

Discusses the concept of kinetic versus thermodynamic control of reactions. Explains on the undergraduate level (1) the role of kinetic and thermodynamic control in kinetic equations, (2) the influence of concentration and temperature upon the reaction, and (3) the application of factors one and two to synthetic chemistry. (MVL)

Describes a laboratory exercise testing the Vine-Matthews-Morley hypothesis of plate tectonics. Includes 14 questions with explanations using graphs and charts. Provides a historical account of the current plate tectonic and magnetic anomaly theory. (MVL)
