Reported is a study to examine relationships between academic and professional factors and the attainment of selected elementary school science teaching competencies. Competencies were measured but no attempt was made to equate the presence of the competencies with effective teaching. The assumption was made that these competencies are part of the…

Many elementary classroom teachers must overcome the following problems in order to teach science effectively: (1) a lack of background in scientific concepts and general information; (2) a scarcity of science equipment and supplies on hand or insufficient funds to purchase them; (3) little basic knowledge of the skills, processes and attitudes…

Reported is a comparison of the effectiveness of two instructional methods of preservice elementary teachers in teaching science as well as a comparison of the relationships of initial attitudes toward teaching science and science process skill competencies to initial teaching behaviors. Forty lower elementary preservice teachers were randomly…

This booklet presents 18 experiments in the chemistry of food, suitable for elementary and secondary school science classes. Experiments deal with an analysis of milk, determinations of the amounts of sulfur dioxide, iron, and fat in foods, and the concentration of vitamin C in fruit juice and iodine in salt. Tests are provided for fats,…

A theoretical model for the production of teacher centered inservice videotapes was developed and applied to produce a structured inservice course in aerospace activities for elementary teachers. Space-science education specialists interested in elementary education viewed segments of the course and were successful when they attempted the…

This document describes a project designed to explore the possibilities of children's learning in mechanics. The principle of the lever, one example of a simple machine, was used in the form of a balance toy. The apparatus was set up as a game in a specially devised learning center. The children made non-verbal predictions as to which way the bar…

Reported is a study to determine if cloze tests are sensitive to gain measurement using two different approaches to science instruction. A secondary purpose was to determine what relationships existed among the scores of 300 fifth-grade students (150 boys, 150 girls), randomly selected from a population of 520 fifth-grade students in Warminster,…

Reported is a study to determine if amplifying elementary reading material through the use of exemplars (based on Ausubel's theory of meaningful verbal learning) would reduce conceptual difficulty and thereby increase reading comprehension. Reading passages were developed for three different elementary science concepts with three levels of…

This study placed emphasis on relevance of the science programs and measured the effect of so doing on twelve intact classes of elementary children's attitude toward science. The purpose of the study was to determine the relative effectiveness of two methods of enriching a science curriculum. A portion of the Conceptually Oriented Program in…

Reported is a study of relationships between teacher's perception of pupils and classroom verbal behaviors among 34 inner-city and 38 outer-city fifth grade science teachers in a large Midwestern city. The Perception of Pupils Adjective Checklist was used. Ten inner-city and ten outer-city teachers were selected from the population for…

The two major objectives of this study were: (1) to develop techniques for quantifying and evaluating properties of a "learning context" (i.e., a sequence of observations generated by subjects in solving a problem), and (2) to determine whether or not there is a relationship between properties of observational sequences generated in solving a…

Included are brief accounts of the position of science education in 16 countries of the Asian region, providing data on present status, current problems, characteristics of teachers, and curriculum characteristics. Both secondary and primary grades are discussed, and, in some cases, teacher training programs described. An interpretive introduction…

This curriculum guide is intended for use in an ungraded science program encompassing grades one, two and three in public elementary schools in southwestern North Dakota. Five major units in the biological, physical and earth sciences and in health education are included. In each unit major concepts to be studied are stated. For each concept,…

Reports and recommendations prepared by working groups on "The Structure of Chemistry,""Graduate Education in Chemistry and Beyond,""Preparing Chemists to Meet Society's Future Needs,""Chemistry for Citizens,""International Aspects of Chemical Education" and the text of two plenary addresses, "Education for Change" and "New Problems Need New…

A 2 x 2 factorial design was used to investigate the effect on teaching competencies (measured by applying the Instrument for the Analysis of Science Teaching, the Classroom Observation Rating Form, and the Teacher Performance Competencies Scale to videotapes of subjects teaching in one-to-one or one-to-two situations), and attitudes (measured by…
