A category system was developed to describe content development in chemistry classes. The instrument had three broad dimensions: the Semantic dimension for coding the intent of the teacher in developing content; the Syntactic dimension for coding the actual meaning of the communication; and the Initiate-Supply dimension for coding the participants…

Reported is a study designed (1) to investigate the relationship between teacher-assigned chemistry grades and the scores obtained on a multiple-choice chemistry test built on taxonomic principles, and (2) to compare the contributions of various predictor variables to the explainable variance of the grades and the total test scores. The sample…

This teacher's guide on nuclear science is divided into two parts. The first part is a discussion of some of the concepts in nuclear chemistry including radioactivity, types of disintegration, radioactive decay and growth, and tracer techniques. The relevant experiments involving the use of radioisotopes are presented in the second part. The…

Student responses to the Learning Environment Inventory were obtained from six physics classes, ten chemistry classes and ten biology classes in eight English-speaking schools in the Montreal Metropolitan area. A three-level, one-way multivariate analysis of covariance with the 15 Learning Environment Inventory Scales as dependent variables and…

Since 1966 the Chemical Society Research Unit in Information Dissemination and Retrieval at the University of Nottingham has been evaluating the use of "Chemical Titles" (CT) and "Chemical-Biological Activities" (CBAC) as current awareness services. Early results of this evaluation led to the Students' Chemical Information…

Part II of the Students' Chemical Information Project (SCIP), designed to spread the use of computer-based information services among research scientists and technologists, contains details of the project operations, statistics, results of questionnaires and research reports from liaison scientists (See LI 002 562 for Part I). Chapter I: Operation…

This volume contains chapters 8 to 13 of the ACS "Modern Chemical Technology" (ChemTeC) curriculum material which is intended to prepare chemical technologists. The content is centered around the background needed to understand the structure of the atom, covalence, electrovalence, elements and compounds, liquids and solutions, and chemical…

Discussed are the goals of the Advisory Council on College Chemistry and the effect on College Chemistry of termination of National Science Foundation funding. Reported are conferences on (1) the relevance of thermodynamics to chemists and engineers and its place in a chemistry curriculum, (2) new approaches to teaching thermodynamics in an…

This booklet was written for students as a source of ideas for research type science projects. Part One shows how three high school students developed individual projects a s a result of asking questions about the same natural phenomena. Part Two contains project suggestions and sample questions designed to stimulate student thinking along…

The investigator attempted to show that the use of behaviorally stated objectives in classes of chemistry would result in higher gains in achievement for students in these classes as compared to those in classes where nonbehaviorally stated objectives are used. The multiple linear regression approach to analysis of variance and interaction…

This unit of instruction provides a laboratory oriented study of the chemical reaction involved in the life processes. Students enrolling in this course should have successfully completed the units on Scientific Mathematics, Introduction to Chemistry, Reactions of Atoms and Molecules, and Chemistry of Carbon and Its Compounds. The booklet lists…

This packet an autoinstructional program for secondary school chemistry students is presented. No prerequisites are suggested. It can be used with high, medium or low level achievers. The behavioral objective is presented directed towards the students' achievement in listing observations made. Equipment and materials needed are listed. A…

This book is intended as a guide for people who are planning chemistry and physics research laboratories. It deals with the importance of effective communication between client and architect, the value of preliminary planning, and the role of the project officer. It also discusses the size and layout of individual laboratories, the design of…

Mathematics and science classes integrated computer science activities into the regular secondary curriculum. This document reports the nature of the computer activities used in conjunction with an algebra II class, a physics class and a chemistry class. A computer programing class was also established as a year-long elective course. Success and…

This paper presents a detailed analysis of the content and format of seven machine-readable bibliographic data bases: Chemical Abstracts Service Condensates, Chemical and Biological Activities, and Polymer Science and Technology, Biosciences Information Service's BA Previews including Biological Abstracts and BioResearch Index, Institute for…
