Discusses how the concept of organoleptic chemistry permeates every modern chemical experiment. Six approaches for developing organoleptic attitudes which are crucial to the experimental aspects are also presented. (HM)

Discusses the results of the 1975 Examination for General Chemistry, and summarizes descriptive statistics as well as ten different subsets of instructional topics. The major results and conclusions are reported in three separate profiles. (HM)

Describes an undergraduate research program in biomedical engineering at the State University of New York at Buffalo. Includes goals and faculty comments on the program. Indicates that 58 percent of projects conducted between 1976 and 1980 have been presented at meetings or published. (SK)

Discusses the nature of light-producing reactions and provides a procedure for demonstrating chemical luminescence using siloxene indicator. Indicates source of this chemical and safety precautions. (SK)

Describes a "gradebook program" capable of recording, editing, recoding, weighting, and scaling multiple choice test scores. (SK)

Presents a list of the producer, catalog number, format, and price of audiovisual aids for: acids, bases, and salts; atomic structure and atoms; biochemistry; bonds; water chemistry (solutions); changes of state; and electrochemistry. Includes a separate list of names and addresses of randomly selected producers of audiovisual materials. (SK)

Provides instructions and rules for a game to teach covalent bonding in which a set of plastic atoms are combined to produce stable covalent bonds. (DS)

Briefly describes the application of thermodynamics (system at equilibrium) to the study of the extraction of metals from their oxides (dynamic situation). It is more relevant to study the temperature variation of the equilibrium constants of the reaction than to study the free energy approach. (Author/SK)

Suggests ways in which chemistry professionals, particularly academic faculty members, might improve the image of chemistry and engineering. Stresses damage done to this image because of recent media coverage regarding misuse and improper disposal of chemicals. (CS)

Discusses how modern mathematical language can be used to develop chemical ideas in class. Examples for the application of Venn Diagrams and Flow Diagrams in teaching chemistry in the Nuffield courses are presented. (HM)

Describes a study of currently available introductory chemistry textbooks for nonchemistry majors. Investigators (one philosopher and one chemist) read books and noted instances of value judgments and content. Findings include uniformity in factual content, and an abundance of value judgments on social, political, and economic issues. (DS)

A questionnaire was administered to first-year biology, physics and chemistry students in an Israeli university to assess their views on the nature of the contribution made by their high school courses to college achievement. Results indicate that high school curriculum influences attitudes, knowledge retention, expectations, and achievement in…

Freshmen college students (N=290) were asked, "What is an atomic orbital?" as a measure of their knowledge after completing high school chemistry. Results suggest that high school chemistry be divided into two levels: (1) procedures and interpretations of classical chemistry and (2) introduction of elementary quantum chemical concepts.…

Illustrates common mistakes teachers usually make when discussing physical phenomena. Presents correct and incorrect explanations for five common science demonstrations. (SK)

Examines whether retesting: (1) affects achievement of students (N=95) grouped according to previous achievement in science; and (2) influences students to delay studying and perform at a low level on initial tests. Also examines whether procrastination of retested students is affected by their achievement level. (DS)
