We are developing a new activity-based unit on global warming and the environment as part of the "Explorations in Physics Curriculum." We describe the current status of this unit, which focuses on helping students understand the greenhouse effect and its relationship to global warming. We outline several problems encountered in testing the unit…

This study summarizes the results of a quantitative synthesis of the retrievable primary research dealing with the effects of new science curricula on student performance. This study synthesizes the results of 105 experimental studies involving more than 45,000 students and utilizes the quantitative synthesis perspective to research integration…

At most land-grant universities in the USA, Introduction to Soil Science is traditionally taught using a combination of lecture and laboratory formats. To promote engagement, improve comprehension, and enhance retention of content by students, we developed a problem-based learning (PBL) introductory soil science course. Students work in groups to…

The Third International Mathematics and Science Study (TIMSS) is the largest, most comprehensive, and most rigorous international comparison of education ever undertaken. During the 1995 school year, the study tested the mathematics and science knowledge of a half-million students from 41 nations at five different grade levels. In addition to…

This document contains the final program and abstracts for the 1997 annual meeting of the National Association for Research in Science Teaching (NARST). Strands of the meeting included "Learning: Students' Conceptions and Conceptual Change"; "Learning: Classroom Contexts and Learner Characteristics"; "Teaching";…

This manual presents a variety of ideas for environmental education projects that range in duration from two weeks to several years. All of the projects are designed to make learning interesting and relevant to the lives of students by enabling them to develop a sense of connection to their world and a framework that empowers them to make positive…

A series of recommendations developed by the Council of Colleges of the Colleges of General and Professional Education (CEGEP) in Quebec (Canada) are presented in this report to the Ministry of Higher Education and Science for redesigning the CEGEP's natural sciences curriculum. The proposed reforms are designed to meet legislative requirements…

Originally developed in an elementary science program called the Science Curriculum Improvement Study, the learning cycle (LC) teaching approach involves students in an active learning process modeled on four elements of Jean Piaget's theory of cognitive development: physical experience, referring to the biological growth of the central nervous…

This report describes the findings of the 1990 National Science Foundation (NSF) Workshop on the Dissemination and Transfer of Innovation in Science, Mathematics, and Engineering Education, and the resulting recommendations for action to the NSF, to university administration and faculty, to professional societies and journals, and to industry. The…

A quantitative synthesis of multivariate studies in science education during the past ten years yields evidence to support a model of achievement in science very much like that currently proposed in the literature of expert problem-solving. Despite previous claims, spatial visualization and verbal ability predict additional variance in achievement…

The National Research Council is coordinating the development of national standards for science education in grades K through 12. By the fall of 1994, National Science Education Standards will be completed and published. The standards will contain narrative descriptions of what all students should be able to do to engage and understand the natural…

The program and abstracts of the presentations of the 1991 meeting of the Society for College Science Teachers are the topics of this report. Society officers are listed, a history of the society is provided, and membership information is given. The presentations reflect different topics in the teaching of college science. The abstracts of…

This paper reports on the evaluation of an 11-week curriculum created to foster seventh grade students' understanding of scientific modeling. In the curriculum, students engaged in model-oriented activities such as creating non-Newtonian computer microworlds to embody their conceptual models, evaluating their models with criteria, and reflecting…

This report summarizes and compares the views of six experts-three university professors and three elementary teacher-concerning elementary-level science teaching. The experts were asked to treat the topic comprehensively by addressing the following: (1) issues of curriculum (goals and objectives, selection and organization of content); (2)…

This document contains issues 83-93 of the curriculum newsletter of Lehigh University's Science, Technology, and Society (STS) program. Each issue contains articles addressing issues relative to STS, course syllabi, reader responses, and announcements. Issue No. 83 discusses establishing an interdisciplinary minor in technology studies at…
