This study was designed to identify those science concepts and mathematical skills that may be the source of student difficulty in learning chemistry as developed by the Chemical Education Materials Study (CHEMS). The instruments utilized were four Achievement Tests prepared by CHEMS. Each test item was analyzed to determine the concepts and/or…

This unit of instruction introduces the measuring of work, power, and energy; forms of energy; conversion and conservation of energy; and types of machines. It is a course suggested for the terminal science student. No requisites for prior course work are suggested. The booklet lists the state-adopted texts in the list of references. It states the…

This unit of instruction is a survey course exploring the areas of nuclear physics, physics of modern discoveries, and their effects on the world of today. No requisites for prior course work, experience, or courses to be taken concurrently are required for enrollment. The booklet lists the relevant state-adopted texts and states the performance…

This monograph is a test of graphing and graph interpretation skills which assesses performance on all the skills of graphing which are contained in the AAAS program, Science - A Process Approach. The testing includes construction of bar graphs, interpreting information on graphs, the use of the Cartesian coordinate system, making predictions from…

Reported is an investigation to determine the nature and extent of student misconceptions in chemical equilibrium and to ascertain the degree to which certain misconceptions are related to chemistry achievement and to performance on specific tasks involving cognitive transformations characteristic of the concrete and formal operational stages of…

Presented is a discussion of the role of explanation and prediction in determining science curriculum content. It is the author's contention that many of the concepts currently presented in high school and college science courses are based on assumptions long rejected as false by scientists because curriculum designers have failed to examine…

The purpose of this study was to analyze the effectiveness of audio tapes when used by poor readers to aid in reading their textbook. Forty-three students, primarily low achievers, were randomly assigned to each of three groups. The course followed a Biological Sciences Curriculum Study (BSCS) book, Patterns and Processes. All sections were taught…

Reported is a study of the verbal behaviors used by biology students in inquiry and noninquiry settings. The population for this study included 10 BSCS teachers who had enrolled for two semesters in an instructional program designed to make teachers aware of alternative skills and strategies of inquiry; to recognize those used in their own…

Science educators and individual teachers have attempted to adapt global learning strategies to the local cultural environment. This research provides empirical evidence for one culture, the Kpa-Mende. Anthropological field methods were used to collect data to develop a base from which to ask meaningful questions about natural phenomena. The…

This biogeography module is designed for students wishing to study evolutionary interrelationships with the physical environment. Topics studied include various aspects of historical biogeography and evolution. Categories included are: (1) barriers to the dispersal or organisms, (2) the zoogeographic regions, (3) genetic change, (4) selection, and…

This manual is a teacher's guide to a self-instructional program in basic physical science, designed for high school students who have not had a course in chemistry or physics. There are six units in the manual relating to these areas: problem solving and experimental procedures; universal standards, metric system and conversion; mechanics; the…

This paper proposes a technique for using the digital computer in science instruction (grades 1-12) which may well obviate the constraints of unreasonable cost and demand for complex and extensive software. Computer Simulated Experiments require a short amount of time at the terminal during which the student collects realistic simulated data.…

The theory of breeder reactors in relationship to a discussion of fission is presented. Different kinds of reactors are characterized by the cooling fluids used, such as liquid metal, gas, and molten salt. The historical development of breeder reactors over the past twenty-five years includes specific examples of reactors. The location and a brief…

Provided is a dichotomous key to the common genera of marine algae and angiosperms which are taken aboard the Orange County Floating Marine Laboratory. It is designed primarily for use by junior and senior high school students. Drawings of representative members of the various genera are included. This work was prepared under an ESEA Title III…

Reported was an investigation of the effectiveness of individualized versus group instruction in ninth grade science. Six classes were matched on the basis of Lorge-Thorndike Nonverbal Intelligence Test scores and placed into three groups: control, experimental, and reference (taking a different science course). The conclusion was: individualized…
