This study replicates part of a 1964 study designed to examine variations in the attainment of cognitive objectives in high school chemistry. In 1964 a traditional curriculum was used, but by 1972 when the data for this study were collected, a modern course based on CHEM study was being used. Scores on a 60-item end-of-course test given to…

This is one of several short-term courses developed to assist in the training of waste water treatment plant operational personnel in the tests, measurements, and report preparation required for compliance with their NPDES Permits. This Student Reference Manual provides a review of basic mathematics as it applies to the chemical laboratory. The…

This module examines the basic properties of soil which have an influence on the success of land treatment of wastes. These relevant properties include soil texture, soil structure, permeability, infiltration, available water capacity, and cation exchange capacity. Biological, chemical and physical mechanisms work to remove and renovate wastes…

The problem of this study was to compare teaching methodology and teaching strategies used in general chemistry courses to the attitudes and values of the students taking those courses. Objectives of the study included: (1) an investigation of the teaching methodology in use in chemistry courses, (2) a study of the attitudes of students toward…

This research was undertaken to determine whether the mathematics course offered to students taking courses in chemical technology was adequate. Students in a regular class and an experimental class were given mathematics and chemistry pretests and posttests. The experimental class was taught using a syllabus designed to maximize the coherence…

Project C-BE and CONDUIT had overlapping research objectives concerning the transferability of computer-related curriculum materials. In this regard, the projects co-sponsored an advertisement placed in the Journal of Chemical Education offering a "Free Demonstration of Computer Based Education in Chemistry." Forty packets were mailed.…

Ninety students in an introductory chemistry class were divided into three groups to test the power of algorithms to increase logical thinking abilities. The experimental group received approximately 10 hours of laboratory instruction based on the use of procedural algorithms. Experiment and control groups were tested for logical thinking…

This book provides information on the many aspects of chemical education at the secondary and tertiary level in the United Kingdom and serves as a guide to the literature and an introduction to the language in the field of chemical education. The first half of the book describes the various bodies and institutions concerned with chemical…

These three questionnaires were developed to assess the attitudes of British secondary students toward scientific subjects as taught in their schools. Each questionnaire contains 33 Likert scale items with five choices ranging from "strongly agree" to "strongly disagree." The subjects of the inventories are: (1) physics, (2)…

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…
