This 1971 revision deals with radioisotopes and their use in power generators. Early developments and applications for the Systems for Nuclear Auxiliary Power (SNAP) and Radioisotope Thermoelectric Generators (RTGs) are reviewed. Present uses in space and on earth are included. Uses in space are as power sources in various satellites and space…

Included are instructional materials designed for use with disadvantaged students who have a limited reading ability and poor command of English. The guide is the first volume of a two volume, one year program in life science and contains these three units and activities: Measurement, 7 activities; Ecology, 12 activities; and Energy Processes, 24…

The major portion of this booklet contains detailed specifications for the content of science courses for grades 10-12 in the Arts and Science, Business and Commerce, and Science, Technology, and Trades Branches of Ontario secondary schools. Chemical, physical, and biological topics are emphasized. Brief notes on other science courses are…

This publication has been prepared as a leadership guide for science teachers, secondary school administrators, and teacher educators who desire to produce competent science teachers. Science taught as inquiry is the central theme, and the "processes of science" are recommended as the proper content for all courses. The guide is organized into…

This study compared two groups of high school biology students with respect to laboratory achievement, learning climate, and laboratory behavior on the part of both students and teachers. A cell physiology and nutrition unit containing ten exercises was utilized by five randomly assigned teachers (86 students) in an open-inductive method and by…

The Physics 12 curriculum guide represents one in a series of science guides especially designed to provide for the pupil whose primary interests are in non-science fields. The program provides study in physics in which fundamental concepts and understandings are developed, mathematical concepts are limited, and students are encouraged to relate…

This booklet is one in the "World of the Atome Series" for junior high school students and their teachers. It describes the fascinating story of the search for the key to the structure of matter. These topics are reviewed: the chemical atom of the 19th century, the planetary atom, the wave atom, inside the elementary particles, and the mystery of…

Force diagrams involving angular velocity, linear velocity, centripetal force, work, and kinetic energy are given with related equations of motion expressed in polar coordinates. The computer is used to solve differential equations, thus reducing the mathematical requirements of the students. An experiment is conducted using an air table to check…

The intent of including history in physics courses is to give young students an increased sense of their own identities and a better understanding of their potential roles in our culture, as well as to show that physics is a valuable activity because it enlarges the variety of human experience. A review of the status of history in secondary school…

Five papers presenting the case for reform of biology teaching, five outlining new approaches to biology curricula (including the role of mathematics), and summaries of the discussions that followed each group of papers when presented at the Organization for Economic Cooperation and Development, introduce the report of the conference proceedings.…

This is a 1971 reprint of the chemistry syllabus printed in 1966 for the state of New York. This course of study presents a modern view of chemistry suitable for pupils with a wide range of skills and abilities. The outline of topics provides the unifying principles of chemistry together with related facts. The principles included in the outline…

This research consists of an examination of the relationship of teacher characteristics to student achievement during the field testing of experimental Intermediate Science Curriculum Study (ISCS) materials. Two approaches were used in determining the characteristics of effective ISCS teachers. In the first approach the variables commonly…

This bulletin sets forth the 65 recommendations of the Commission on Professional Standards and Practices of the National Science Teachers Association "on the kinds and quality of facilities needed for good science learning and teaching, on the conditions of instruction necessary to promote good teaching, and on the provisions that a school should…

This physics laboratory manual is the result of curriculum development begun at Aviation High School (New York City) in 1967. It represents a semester of advanced laboratory work for those students who have completed the usual course in physics. The 91 laboratory experiments included in the manual have been developed and modified through use for…
