The author's primary goal was to investigate the relative viability of different kinds of open teaching. Project Learn, an open elementary classroom, met all the criteria set forth to be called such and was selected for the study. The independent variables were: teacher-guided instruction, small-group instruction, and individual-oriented…

Reported is an assessment of a competency-based physics course designed to develop concepts through an activity-centered approach incorporating the processes of science. It was assumed that such a strategy would enhance a future teacher's understanding of science concepts and processes in addition to developing more positive attitudes toward…

The concept, organization, and operation of an interactive network for curriculum change is described, and data concerning the impact of this collaborative activity on instructional practice in public schools and colleges is presented. Specifically, the paper focuses on (1) the characteristics of a prototype model for harnessing the innovative…

British science curriculum improvement projects on the elementary and secondary school levels are reviewed in this volume to indicate their implications for the development of second-generation programs in the United States. Included in the British second-generation program category are: the Scottish integrated courses, Nuffield combined science,…

Three studies are reported for children participating in the Elementary Science Study (ESS) program. They are the cognitive and affective performances and the classroom learning environment. Three groups of ESS children were evaluated: nine-year-olds, ten-year-olds, and eleven-year-olds. Each age group contained 30 randomly selected subjects. The…

The study was conducted to determine the influence of process-oriented television science on teacher and student process and concept achievement, classroom teacher process questioning, and the relationship between achievement and questioning behavior. Grades one through four were used for the study. Fifty-four volunteer teachers were randomly…

This evaluation report investigates the effectiveness of the Unified Science and Mathematics for Elementary Schools (USMES) program during the academic year, 1973-74. USMES is a curricular program designed to develop the problem solving abilities of students attending grades one through eight. The goal of the program is the development of 32…

This is one of five volumes prepared to describe various aspects of the Del Mod System. This volume deals with the evaluation of the Del Mod System. Included are the following: (1) Del Mod Responsive Evaluation; (2) Evaluation Outcomes; (3) Validation of the Del Mod Responsive Evaluation Process; and (4) Conclusions. Appendices include: (A)…

Two-column objectives are listed for an integrated science curriculum (Grades K-12), often subheaded according to science area (physical sciences, physics, biology, chemistry, general science) and grade level. Objectives that relate characteristics and forms of energy to energy conservation are stressed in the primary grades (K-6). In grade 7, the…

Two-column objectives are listed for an integrated science curriculum (grades K-12), often subheaded according to science area (biology, general science, physical science) and grade level. The focus of grades K-6 is an acquaintance of the student to: (1) the study of matter, its states, characteristics and properties, (2) structure of the atom,…

Two-column objectives are listed for an integrated science curriculum (grades K-12), often subheaded according to science area (biology, health, general science, physical science) and grade level. Concepts regarding characteristics of living things are stressed in objectives for the primary grades (K-5), and reproductive biology is covered…

This study was designed to determine if special elementary students could learn basic science concepts. Students included the physically handicapped, emotionally disturbed, educable mentally retarded, and trainables. Modules with pretest and posttest were used. Results indicated that regardless of handicap, students were able to work successfully…

Selected units from a series of 26 activities on the concepts of force, pressure, density and upthrust are provided. The units are intended to be used in a modular approach in such a way as to allow students at different developmental levels to gain an understanding of these ideas appropriate to their abilities.

Reports on a study which investigated the order of acquisition of intuitive notions of qualitative speed. Results indicated that an array of prerequisites, equivalent, and independent relationships existed among the tasks administered. Confirmed the evolution of reasoning for notions of qualitative speed found by Piaget. (Author/TW)

Describes the priorities and programs supported by the new assistant director for science and engineering education at the National Science Foundation (NSF). Collaboration among academic institutions and the private sector, teacher training efforts, and scientist/engineer professional involvement are stressed. (DH)
