The purpose of this volume is to present a body of basic information about the Great Lakes that is current and based on sound research. Such information is frequently difficult to locate, especially in one reference, and equally difficult to decipher and evaluate. The 16 essays contained in this book deal with a variety of topics including the…

This study guide was designed to help teachers and students understand the problems surrounding solid wastes. It includes an overview of solid waste and recycling, a glossary, suggested activities and a list of resource publications, audiovisual materials and organizations. There are 19 activity suggestions included in this guide designed for use…

The teacher is one of the most important variables for maintaining or developing excellence in education. According to many surveys many teachers of high school physics earned their degrees in other fields. This paper deals with preservice and inservice high school physics teacher education. Topics include: (1) what physics teachers are expected…

This book is for people that want to know more about the oceans, its inhabitants, and the ocean processes. The main text of the book describes individual marine ecosystems including offshore open water, benthic, nearshore tropical, nearshore temperate, and nearshore arctic ecosystems. Discussed are some of the basic ecological principles found…

The Government-University-Industry Research Roundtable was created to provide a forum where scientists, engineers, administrators, and policy makers from government, universities, and industry can come together on an ongoing basis to explore ways to improve the productivity of the nation's research enterprise. Roundtable Working Group One, which…

Students of reasoning have long tried to understand how people revise systems of beliefs. This paper maintains that people often change their beliefs in ways driven by considerations of explanatory coherence. In this report, a computational model is described of how experimental subjects revise their naive beliefs about physical motion. First,…

Sci-Math is an interdisciplinary curriculum intended to help students develop the math skills needed for science, especially dimensional analysis, ratio, and the concept of proportion. Sci-Math is divided into two modules with each module having a student and teacher's guide. Module one is a pre-algebra module dealing with the arithmetic and logic…

Presented are the findings of a survey of students who are, or have been, participants in the King Foundation Forgivable Loan Program in Texas for preservice secondary mathematics or science teachers. Data on the number of respondents in the program and not in the program, and their reasons for staying or leaving (that is, teaching mathematics or…

Questionnaires with over 400 items were administered to key teachers of the 1982 Search for Excellence in Science Education programs. It was hoped to compare the characteristics of teachers of exemplary programs with those possessed by teachers in general. Results are presented under the following headings: (1) qualifications of science teachers;…

The Junior High School Management Improvement Study (JMIS) was a field experiment conducted to verify and extend findings of previous research in English and mathematics classes. Using student behaviors (on task, off task, and disruptive behavior) as criteria of management effectiveness, this study investigated classroom management practices in 26…

One area explored in the second (in-depth) phase of the Learning in Science Project was "children's science," defined as views of the world and the meanings for words that children have and bring with them to science lessons. The investigation reported focuses on the concept of "electric current" held by 43 elementary school…

Two student populations of 13-year-olds in Ontario (Canada) were assessed as part of the 1988 International Assessment of Educational Progress (IAEP): French- and English-language students. Results confirm findings of differences in mathematics achievement seen earlier in the Second International Mathematics Study. Ontario French-language students…

The purpose of this project was to construct a valid and reliable noncurriculum specific measure of integrated science process skills intended for use with middle school students. The major efforts in test development were focused on the refinements and modifications of the set of objectives and test items assessed by the existing Middle Grades…

This study investigated the seating patterns of target students in science classrooms to see if there was an action zone or t-zone present. Fifty-six physical science and chemistry classes were observed using the Brophy-Good Teacher-Child Dyadic Observation System. Target students were identified and their interactions were compared to non-target…
