Individualized Learning System Chemistry (ILS Chem) is a multi-media approach to learning basic chemical principles and their application to man's daily existence in which the student proceeds at his own rate through a series of instructional loops. This is a computer-managed, competency-based instructional system in which the individual student…

The purpose of this study was to compare the effects of various teaching practices and classroom organizational patterns upon achievement and understanding of science of students studying materials of the Nebraska Physical Science Project (NPSP), an integrated chemistry-physics course, and to investigate these practices and patterns and the role…

This book is intended to serve as a source of ideas for devising simple scientific activities, investigations, and experiments and for the construction of necessary equipment using available materials. This revision of an earlier edition reflects modern approaches to science teaching at the elementary and secondary school levels. This edition has…

The "Television Polytechnic" program of 1966 - 1970 was a joint effort of the Polish Ministry of Higher Education and Polish Television to provide televised education for working students. The subjects taught were those normally included in the first two years of the higher technical schools--math, physics, geometry, chemistry, mechanics…

The Cambridge Crystallographic Data Centre is concerned with the retrieval, evaluation, synthesis, and dissemination of structural data based on diffraction methods. The source of input is almost entirely primary journals. Bibliographic information and numeric data on crystal and molecular structures are on magnetic tapes. The bibliographic file…

A study was performed to determine the effectiveness of short-term, tutorial-type computer-assisted instruction (CAI) in selected topics in high school chemistry. To determine CAI effectiveness, post-tests specifically designed for this study were administered at the completion of instruction and sixty days later. Control group students generally…

Beginning in Fall, 1975, applicants to Liberal Arts, Technology, and Forestry at the University of Minnesota could submit scores on either the Preliminary Scholastic Aptitude Test (PSAT) or the American College Testing Program's aptitude battery (ACT) to satisfy entrance testing requirements. This study determined that new course placement…

This student booklet is one of a set of eight designed to be used in a self-paced introductory chemistry course in conjunction with specified textbooks and computer-assisted instruction (CAI) modules. Each topic is introduced with a textbook reading assignment and additional readings are provided in the booklet. Also included are self-tests (and…

This booklet, one of a series developed by the Frederick County Board of Education, Frederick, Maryland, provides an instruction module for an individualized or flexible approach to 7th, 8th, and 9th grade science teaching. Subjects and activities in this series of booklets are designed to supplement a basic curriculum or to form a total…

Data from experiments with high school chemistry students revealed (1) that remediation positively influences cognitive achievement and retention, and (2) recycling, which introduces alternate materials and activities under teacher direction, provides more optimum learning conditions than repeating the learning activities and reviewing the reading…

Investigates the effectiveness of an individualized approach to an introductory college chemistry course, including a computer-managed instructional system, and its effect on student attitude. Description of the Individual Learning System Chemistry course; procedures and results of the study are also presented. (HM)

Trace organic analysis (TOA) is seen as a more useful way to quantify environmental pollutants. Current practices and future trends are discussed in detail. Seven steps in TOA are identified: collection, storage, extraction, concentration, isolation, identification, and quantification. (MA)

Attainment of laboratory course objectives was compared for tenth and twelfth grade Israeli students using two chemistry curricula: An Experimental Chemistry Program for Secondary Schools (ECPSS) and the CHEM Study program. ECPSS students more often than non-ECPSS students, and ECPSS girls more often than boys felt they had achieved the…

Presents an analytical or inorganic chemistry laboratory experiment in preparing nickel macrocyclic complex. (SL)
