Two different methods of collecting information about student activity in the laboratory were compared using a series of videotape recordings. One method was based entirely on the systematic observation of student behavior (interaction analysis); the second method involved students describing their laboratory activities while watching excerpts…

This document is a collection of 43 overhead transparency masters to be used as teaching aids in a course of study involving soils such as geology, agronomy, hydrology, earth science, or land use study. Some transparencies are in color. Selected titles of transparencies may give the reader a better understanding of the graphic content. Titles are:…

This study, an extension of previous studies, compared the views of freshmen college biology, chemistry, and physics students (N=229) with those of high school seniors (N=437), focusing on: (1) interest in different high school topics; (2) nature of high school laboratory experiences; (3) use of innovative instructional strategies in high school;…

Focusing on the continuing education (CE) of scientists/engineers in North Carolina working in small (1-500 employees), geographically dispersed companies, this study: 1) identified and described CE resources currently being used by scientists/engineers to maintain and extend their professional competence and capabilities; 2) determined the extent…

This material was developed to provide an application of matrix mathematics in chemistry, and to show the concepts of linear independence and dependence in vector spaces of dimensions greater than three in a concrete setting. The techniques presented are not intended to be considered as replacements for such chemical methods as oxidation-reduction…

Volume 8, No. 2 of Investigations in Science Education contains critiques of articles dealing with science education research about various aspects of instruction. Also included are five responses from authors of articles to critiques of their work as it has been reported in professional journals. In total, this volume contains 10 critiques and…

The results of a National Science Foundation survey of 181 engineering colleges are summarized in this report which focuses on the extent of and reasons for faculty vacancies and effects of staffing problems. Major findings indicate that: (1) most deans of engineering colleges believe that difficulties in filling faculty slots have impaired the…

Presented are the teacher's guide and student materials for one of a series of self-instructional, computer-based learning modules for an introductory, undergraduate chemistry course. The student manual for this unit on chemical equilibrium calculations includes objectives, prerequisites, a discussion of the equilibrium constant (K), and ten…

Presented are the teacher's guide and student materials for one of a series of self-instructional, computer-based learning modules for an introductory, undergraduate chemistry course. The student manual for this acid-base equilibria unit includes objectives, prerequisites, pretest, a discussion of equilibrium constants, and 20 problem sets.…

This study guide is part of a program of studies entitled Science and Engineering Technician (SET) Curriculum. The SET Curriculum integrates elements from the disciplines of chemistry, physics, mathematics, mechanical technology, and electronic technology with the objective of training technicians in the use of electronic instruments and their…

Provides information on cellular morphology and physiology, including general cell characteristics, the nucleus, ribosomes, endoplasmic reticulum, Golgi apparatus, lysosomes, mitochondria, microtubules, microfilaments, and membranes. Focuses on membranes which are postulated to play an important role in many aspects of health and disease.…

As a result of the increasing human impacts upon global marine and aquatic resources, there is an increasing need to produce fishery science experts who can contribute to management, planning, and research. The Food and Agricultural Organization of the United Nations and Unesco cosponsored a workshop to examine the present status and problems in…

During the six-year period (1975-80) the College of Technology of Temple University conducted an experimental project at the pre-college level aimed at the early identification of disadvantaged minority students seeking careers in engineering and/or engineering technology. The program was designed to encourage inner-city Philadelphia black and…

Project SOAR (Stress on Analytic Reasoning) is a pre-college summer program for natural, health, and mathematics science majors jointly developed and conducted by the Departments of Biology, Chemistry, Mathematics/Computer Science and Physics/Pre-Engineering at Xavier University of Louisiana. The program objective was to increase performance in…

Minorities have for some time been underrepresented in the technical fields, such as engineering and computer science. This development is known to be caused by a variety of factors, but the primary purpose of this report is to help identify those factors that adversely affect the cognitive development of the technical bilingual student in terms…
