This study was conducted to (1) identify certain concepts of relativity, and (2) determine the relationship between understanding of these relationships achieved by pupils in grades 4-8 (as indicated by objective test scores) and such variables as grade level and mental ability. Several related sub-problems were also identified. A conceptual…

This study was designed to evaluate the success of an experimental secondary school course for fostering scientific literacy and the development of scientific attitudes. Students were matched using I.Q., sex, grade level, involvement with formal science courses, and cumulative grade point average. Twenty-one "self selected" eleventh and…

Determined were differences in understanding the nature of science and scientists and in subject matter achievement between seventh grade students who studied source papers as part of their instruction in science and those who did not. Experimental students analyzed ten source papers related in subject matter content to the local course of study.…

Proposed is an organizational plan for a K-12 science curriculum. The paper is organized into three parts. Part I proposes certain general objectives of instruction as a framework on which a K-12 science curriculum is to be built. The concepts of general education and scientific literacy are discussed in detail. Part II considers the "forces"…

Compared were programed materials and conventional methods for teaching two units of eighth grade science. Programed materials used were linear programed books requiring constructed responses. The conventional methods included textbook study, written exercises, lectures, discussions, demonstrations, experiments, chalkboard drawings, films,…

Investigated was academic achievement of Earth Science Curriculum Project (ESCP) students in permissive and authoritarian classes. Authoritarian and permissive teachers were identified in the formal ESCP program using McGee's F-Scale; Form 30. Random samples of students and teachers were chosen from the 15 test centers throughout the United…

Compared was the status of science education in high schools in the state of Iowa during the 1957-58 and 1966-67 school years. Data for 1967 were obtained from the State Department of Public Instruction and from visits to 60 schools. Some of the findings related to students and teachers are (1) schools offered more science courses in 1967 than…

The bulletin was prepared as a general guide to encourage the use of safe practices in science laboratories in Florida schools. The guide begins with an outline of recommended emergency procedures. Chapter I discusses the importance of safety in the science program. Chapter II discusses handling and storage of equipment, and designing laboratory…

This annotated bibliography, intended for elementary and secondary school teachers, their pupils, and general adult readers contains grade level coded lists of books, reference works, periodicals, and teaching aids dealing with astronomy and space flight subjects. The reading material is listed alphabetically by author. The teaching aids in Part…

This publication provides twelve model spacecraft construction plans for use by secondary school teachers in industrial arts classes. These models were adopted and developed from plans supplied by the National Aeronautics and Space Administration and are representative selections from the many spacecraft used in space exploration programs. Some…

The effects of two different types of bilingual science instructors upon student science achievement in a bilingual science program were investigated. The influence of student bilingual dominance upon science criterion scores were used to determine program success and teacher effectiveness. Sixteen selected junior high schools in New York City…

Investigated was a team approach for teaching high school biology. Students in six high schools in New York state were involved in the study. Achievement gains on tests were compared between students in team approach classes with students in conventional classes. Few differences were observed between groups and many of these were contradictory. It…

This study involved examining an instructional unit with regard to its concept content and appropriateness for its target audience. The study attempted to determine (1) what concepts are treated explicitly or implicitly, (2) whether there is a hierarchical conceptual structure within the unit, (3) what level of sophistication is required to…

Compared, for selected outcomes, were integrated chemistry-physics courses with chemistry and physics courses taught separately. Three classes studying integrated Physical Science Study Committee (PSSC)-Chemical Bond Approach (CBA), and three classes studying integrated Physical Science Study Committee-Chemical Education Materials Study (CHEMS)…

Included in this study were (1) construction of a teaching unit on charge cloud atomic structure for junior high schools, and (2) testing of student achievement based upon use of this unit as compared to students using a conventional approach. A unit was constructed utilizing material judged to be appropriate at this level by a group of chemists.…
