There is general agreement that the current teaching of secondary science is not as good as it should be. Different critics identify different weaknesses, but there is agreement that students are not learning how scientists make knowledge claims and use this knowledge. This paper assumes that one powerful influence on the development of teachers…

This study addressed whether the educational impact of a zoo visit can be enhanced through the provision of appropriate instructional supports such as preparatory trainings or orientations. One important function of the educational process, in contrast to providing direct information or skill development, is to make the learner more sensitive to…

This study examined teachers' content knowledge about the nature of science and how this knowledge was expressed in their classrooms. Understandings about science influence not only explicit lessons about the nature of science, but also shape an implicit curriculum concerning scientific knowledge. Consideration was also given to ways in which…

The Biological Science Curriculum Study with support from others conducted a three-year project (ENLIST Micros II) to develop and test a model for implementing educational computing in science courses. Descriptive data on background characteristics, prior experience with microcomputers, and educational level of the leaders and new participants was…

This handbook is a product of a research project conducted in North Carolina to identify science competencies taught in vocational agriculture programs. Specifically, two vocational agriculture courses were included in the study: Introduction to Agriculture/National Resources and Ornamental Horticulture I. Of the 60 competencies in the…

Proper installations, inspections, operations, maintenance and repairs of wastewater collection, conveyance and treatment facilities have a significant impact on the operation and maintenance costs, and the effectiveness of these facilities. This manual is the first volume of a two-part program designed to provide wastewater collection system…

The ocean affects all of our lives. Therefore, awareness of and information about the interconnections between humans and oceans are prerequisites to making sound decisions for the future. Project ORCA (Ocean Related Curriculum Activities) has developed interdisciplinary curriculum materials designed to meet the needs of students and teachers…

Twenty-two speakers attending the University of Oregon College of Education's Third Annual Summer Conference, entitled "The Computer: Extension of the Human Mind," in July, 1982, submitted their papers for publication in this volume of conference proceedings. Papers of a wide-ranging speculative or theoretical nature were presented in…

Wait time, or the pauses between questions and responses, has been demonstrated to be an important factor influencing classroom learning. This paper reviews the key variables that have emerged in wait time research over the past 20 years. Progress in defining and measuring wait time has resulted in improved methodology for wait time research.…

The effectiveness of teaching academic courses such as mathematics and science in a foreign language has been investigated by several international studies in the literature. Even though the studies conducted have brought up contradictory results, most of them reveal that learning academic courses through a foreign language medium may pose…

This study compares the effects of delivery medium (online vs. face-to-face) and facilitator content expertise on academic outcomes in a problem-based learning (PBL) course in anatomy for pre-health/medical majors. The content of online PBL sessions was examined to gain insight into the problem-solving process taking place in these situations.…

This is a summary of a final report which was based on a survey of the literature on needs and practices in pre-college social science education for the period 1955 through 1975. The summary contains a brief introduction, a description of procedures followed in the study, and a summary of findings. The findings are presented as summary statements…

This is a status report based upon the review, analysis, and summarization of literature related to pre-college science instruction, science teacher education, and needs assessment efforts. The report identifies trends and patterns in the preparation of science teachers, teaching practices, curriculum materials, and needs assessments in science…

Prepared for the National Science Foundation (NSF), this report summarizes the development and work of the Outdoor Biology Instructional Strategies (OBIS) project from 1972 to 1979. One hundred activities for ten- to fifteen-year-olds in community groups (scouts, clubs, camps, churches, etc.) were developed, field tested, revised, and made…
