This booklet is one of the booklets in the "Understanding the Atom Series" published by the U. S. Atomic Energy Commission for high school science teachers and their students. Discussion concentrates on the radiological and thermal aspects of the environmental effects of nuclear power plants; on the procedures followed by the Atomic Energy…

This booklet is one in the "World of the Atom Series" for junior high school students and their teachers. It describes the sources, methods for detection, and useful applications of the invisible radiation that occurs naturally on earth. Numerous photographs are included throughout the text. (PR)

This booklet is part of the "Understanding the Atom Series," though it is a later edition and not included in the original set of 51 booklets. A basic survey of the principles of nuclear energy and most important applications are provided. These major topics are examined: matter has molecules and atoms, the atom has electrons, the nucleus,…

The development of the Regional Marine Science Project in Carteret County, North Carolina, is portrayed in this booklet. Established with Elementary and Secondary Education Act (ESEA) Title III funds in 1966, the project has evolved from one high school course in marine ecology to numerous courses and activities at all levels, primary through…

This second draft of a manuscript for a high school engineering and technology course uses case studies as its format. The principles associated with various engineering problems are presented along with their effects on daily life. Topics include the computer, the automotive power system, satellite communications, the petroleum industry, water…

Two pre-service science teacher education programs, one (project) utilizing classroom experience in urban and suburban schools prior to student teaching and the other (non-project) based on methods courses and other university courses with little early classroom experience before student teaching were compared by administering questionnaires and…

Students (comparable in intelligence and ability) in slow-learning classes using either "Biological Sciences Curriculum Study (BSCS) Special Materials" or some other slow-learner biology materials, were compared on the basis of scores on the "Nelson Biology Test", the "Biological Sciences; Patterns and Processes Final…

Eighth grade students using the Biological Sciences Curriculum Study (BSCS) Blue Version materials in a typical classroom setting with large group instruction were compared with students in an "individualized" class who were allowed to work through similar materials at their own rates. Both classes were initially comparable with respect…

Grade 10 students using the Chemical Bond Approach (CBA) materials in a typical classroom setting with large group instruction were compared with students in an "individualized" class using a laboratory-centered, self-paced approach. Both groups were initially comparable with respect to grade nine scores on the "Iowa Test of…

This is the first part of a national study on science instruction in secondary schools of the United States. Questionnaires (copies appended) sent to the principal and to a randomly selected science teacher in 2,019 public secondary schools, selected by multi-stage random samples of Great Lakes and Far West region schools, provided information…

This exploratory study compared alternate theories made during inquiry lessons by students in the classroom and those held by student teachers. The rationale of the study is based on the author's belief that student teachers present data in such a manner that students are caused to form alternate theories. Such alternate theories are mostly…

Included is the prescribed syllabus in biology for the Scottish Certificate of Education. In two separate sections, the syllabus topics and specimen questions for final examinations are explained. This syllabus is intended to present biology as knowledge about living organisms without making the conventional division between plants and animals.…

The State Department of Education for South Carolina has prepared this publication to help administrators and curriculum planners in selecting and evaluating science instructional materials for use in their schools. The report is divided into three major parts for elementary science (K-5), middle school science (6-8), and high school science…

This study was designed and conducted to determine the effect of one semester of study of one of the Blue, Green or Yellow Versions of Biological Sciences Curriculum Study (BSCS) biology on the scientific attitude of tenth-grade public shchool biology students. Twelve biology teachers participated in the study by administering the Scientific…

The publication presents outlines of some of the difficult experiments suggested in the chemistry syllabus for the Certificate of Sixth Year Studies in Scotland. The experiments included in the publication form a small part of the total experiments suggested in the syllabus. Simple experiments, the details of which are available in textbooks, are…
