Sixty-six elementary education upperclassmen were tested to determine their Piagetian stage of intellectual development. Results indicated 26 percent were very formal, 52 percent formal, 15 percent transitional, and 8 percent concrete. (SL)

Investigated were operative comprehension differences between 239 sixth and eighth grade pupils in activity oriented science programs and 249 students in a textbook oriented science program. Results indicated no differences among sixth graders, but activity oriented eighth graders scored higher than textbook oriented students. (SL)

Discusses teaching science at the secondary and college levels and proposes a one-year unified science course organized around the human system. It would emphasize the basic principles of biology, chemistry, and physics. (SL)

Ninety-two seventh grade students were assigned to three testing contingencies; no retesting, optional retesting, and mastery retesting. They were compared for achievement, anxiety and attitude. Optional retesting and mastery retesting were found better for achievement, optional retesting better for attitude, and no treatment difference related to…

Two pilot studies with 22 mildly retarded children indicate that the Science Curriculum Improvement Study (SCIS) Beginning unit aided development of I.Q. and reading readiness. (SL)

Discusses problems encountered in formal procedures for examining concepts to determine how they might be taught and presents alternate formats for presenting concepts. Nine examples are included. (SL)

Describes a performance based teacher education study, with 27 student teachers. Investigated were cognitive statements, reinforcement patterns, effects of treatment on individuals, identification of individuals responding well or poorly, and performance criteria specified in measurable terms. Results indicated methods employed were effective. (SL)

Panels of 30 "outstanding" educators in Colorado and Georgia rated 23 basic competencies for teaching secondary school science. Means, standard deviations, and rakings of the 23 basic competencies and 20 added competencies are given. Identified were seven fundamental areas of skills representing basic science teaching competencies. (SL)

Describes use of focused and open-ended instruments in evaluating an introduction to teaching preservice education course which provide early field-based experience to help students decide if they want to be teachers. Six instruments, data obtained, and conclusions are described. (SL)

Presented is a theoretical, hierarchical model of abstraction designed to provide a systematic theoretical framework for future research into abstract learning. A test of the model with 149 subjects supported the assumption that the hierarchical model of abstraction is valid. (SL)

Describes a methodology utilized to teach 61 concrete operational ninth grade students the formal operational ideas of density and relative density. Analysis of the success of the teaching method indicated 25 students finished with a full understanding of density, 26 gained some understanding, and 10 gained little or no understanding. (SL)

Presented are five arguments for implementing the affective objective of "develop a good attitude toward learning and teaching science" for preservice science teachers. (SL)

Presents a comparison of attitudes toward physics and chemistry by 300 eleventh and twelfth grade students. Attitudes toward chemistry were more positive than towards physics; chemistry was considered less masculine, and physics was considered more important. (SL)

Presents four bibliographies: (1) Research Reviews in Science Education; (2) Historical Documents in Science Education; (3) Historical Documents of Significance to Science Educators; and (4) Research and Development in Science Education, A Bibliographic History. (MLH)

A group of secondary science students showed significant gains, as measured by two separate instruments, in the understanding of the procedures, processes, and methods of science after participating in a six-week Secondary Science Training Program (SSTP). (MLH)
