The Field Operations and Enforcement Manual for Air Pollution Control, Volume II, explains in detail the following: technology of source control, modification of operations, particulate control equipment, sulfur dioxide removal systems for power plants, and control equipment for gases and vapors; inspection procedures for general sources, fuel…

The author sought to establish reasons for secondary school students' selecting chemistry as part of their course of studies. Another aspect of the study related to predictor variables and the study of chemistry, and a third aspect related to the type of curriculum used--Chemical Education Materials Study (CHEMS) or traditional. Eleventh-grade…

This study was concerned with the effect of subsuming concepts on student achievement and the interaction effect of subsumers with high and low organizing ability. One hundred forty-three subjects (Ss), enrolled in six sections of a class in undergraduate chemistry, were administered an organizing ability test and rank ordered according to the…

This research investigated the need to apply appropriate results of research in pedagogical techniques of questioning to accomplish maximum achievement through the use of high-level questions and to encourage thought and participation in the learning process. A unit on radioactivity and radiation was prepared, validated and taught by 14 carefully…

Reported is a study designed to (1) describe the variations which occur in the attainment of cognitive objectives in high school chemistry, (2) identify patterns of achievement in terms of these cognitive objectives, and (3) investigate the relationship of achievement of these objectives and their patterns to certain personal, attitudinal, and…

The history of the planning, funding, preparation of preliminary materials, teacher preparation, trial teaching, evaluation, revision and final publication of the CHEM Study materials is presented. The anecdotal account points out the difficulties encountered, the solutions found and the pitfalls avoided so that the experience gained may be useful…

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…
