This study investigated the effect voluntary or mandatory adoption of the Earth Science curriculum had on instructional procedures, teacher educational opinion, student achievement in earth science, and student ability to employ the processes of science. Selection of teachers resulted in three groups: (A) those forced to adopt the new syllabus,…

This bulletin of the Scottish Schools Science Equipment Research Centre provides information to teachers on a variety of topics relating to the use of equipment in science instruction. An editorial opinion argues that science curricula developed in England should not be adopted unchanged in overseas countries (such as Iran), but should be…

This bulletin of the Scottish Schools Science Equipment Research Centre provides information to teachers on a variety of topics relating to the use of equipment in science instruction. The introductory remarks deal with an assessment of electronic calculators suitable for use in schools. The section entitled "Physics Notes" lists surplus…

This bulletin of the Scottish Schools Science Equipment Research Centre provides information to teachers on a variety of topics relating to the use of equipment in science instruction. The introductory remarks deal with some of the consequences of introducing package-deal science courses in underveloped countries and, in particular, discuss the…

This third unit in chemistry is considered for any chemistry student and particularly the college-bound student. An understanding of the material included should enable the student to understand better the concepts in the Dynamic Nature of Atoms and Molecules which are essential for Organic Chemistry, the Chemistry of Carbon and Its Compounds and…

The purpose of this study was to identify: (1) the types of accidents and the areas in which they occur in the high school biology, chemistry, and physics laboratory; (2) the contributing factors that cause accidents; and (3) the preventive measures practiced, and the success of the preventive measures. Four hundred and thirty science teachers…

A new method of constructing tests is presented in this article for the purpose of developing a test from student perception of the course. The Test on Understanding Science (TOUS) and the Science Process Inventory (SPI) were used as sources of items. A random sub-sample of 921 students, taking both the pretest and posttest of TOUS and SPI during…

Reported is a study on the use of quantitative data in evaluating a science course for the purpose of introducing an alternative form of information presentation capable of supplying qualitative feedback valuable to students, teachers, and curriculum developers. Fifty-five teachers, randomly selected during the 1967-68 Project Physics (PP)…

This paper describes the biology program at Munster Senior High School, Munster, Indiana. It is an individualized curriculum utilizing a multi-sensory systems approach, and is presently taught by a team of three teachers and one para-professional to 458 general biology students and 36 advanced biology students. Each student must complete 24 units;…

This unit of instruction was designed as a basic course involving the study of light, sound, and heat at the junior high school level. The booklet lists the relevant state-adopted texts and states the performance objectives for the unit. It provides an outline of the course content and suggests experiments, demonstrations, field trips, and topics…

Political and social implications of biological research, with particular reference to consequences for education, are discussed in this collection of papers presented at the 1969 convention of the National Association of Biology Teachers. Commentary papers by a panel of three, including at least one high school biology teacher and one expert in…

Biological principles related to the theme "photosynthesis and Energy Relationships" were specified, ordered according to Gagne's hierarchical learning theory, and their attainment by students in grades 5, 7, and 9 measured by a 100-item test developed for the purpose. Each succeeding grade level achieved significantly higher scores;…

This student workbook contains units five and six of a six-unit physical science course. The program is intended for high school students who have not had a chemistry or physics course, and is designed to be self instructional. Unit five involves experiments and problems in these subject areas: temperature versus heat; units of heat; specific…

The historical development of rocketry and nuclear technology includes a specific description of Systems for Nuclear Auxiliary Power (SNAP) programs. Solar cells and fuel cells are considered as alternative power supplies for space use. Construction and operation of space power plants must include considerations of the transfer of heat energy to…

The operation of nuclear rockets with respect both to rocket theory and to various fuels is described. The development of nuclear reactors for use in nuclear rocket systems is provided, with the Kiwi and NERVA programs highlighted. The theory of fuel element and reactor construction and operation is explained with particular reference to rocket…
