The use of mathematical models in the experimental analysis of behavior has increased over the years, and they offer several advantages. Mathematical models require theorists to be precise and unambiguous, often allowing comparisons of competing theories that sound similar when stated in words. Sometimes different mathematical models may make…

This report describes an experiment to introduce freshmen science students to inquiry-based learning. The overarching theme was the communication of scientific information to the public by the mass media. Students, working in groups, deconstructed news items (many dealing with basic biomedical issues) and assessed the veracity of statements with…

We present an alternative to a traditional first-year chemistry laboratory experiment. This experiment has four key features: students utilize stoichiometry, learn and apply principles of green chemistry, engage in authentic scientific inquiry, and discover why each part of a scientific lab report is necessary. The importance and essential…

This bibliography cites sources to assist middle, junior, and senior high school students and teachers in planning, preparing, and executing science fair projects in the environmental sciences. In addition, a few books with experiments suitable for elementary grade students are included. The listing includes: (1) 5 introductory texts; (2) 31…

Network Science projects are endeavors in which a number of classrooms conduct the same scientific experiment and pool their data using World Wide Web technology. This paper reviews selected findings from research on these projects and describes the recent Web applications that were developed in response to these findings. Findings indicated that…

The primary goal of this guide is for children to become familiar with the concept of cycles and to learn that some human activities can cause changes in their environment. Although the guide addresses Earth's components, it does so from the perspective of space to show the planet as a large system with interacting parts. To demonstrate on a much…

Some methodological issues in the study of levels of knowledge are reviewed, and needs for further research are explored, drawing on an analysis of 12 studies reported since the late 1970s. In the 12 studies, 16 quantitative experiments were conducted. These were assessed for internal and external validity. Analysis revealed some shortcomings in…

This book is designed to provide knowledge about educational research and to help graduate students in education organize and conduct their own research. No prior familiarity with the principles, procedures, or terminology of educational research is required. Chapters are: (1) "Educational Research: Its Nature and Rules of Operation"; (2) "Types…

This guide is support material for geometry teachers in middle schools or high schools in South Carolina. The guide describes the content of each program in the television series and suggests further learning activities for the students. The geometry that underlies the world around us is presented through applications. Contents of the series…

The Zimbabwe Secondary School Science Project (ZIM-SCI) developed student study guides, corresponding teaching guides, and science kits for a low-cost science course which could be taught during the first 2 years of secondary school without the aid of qualified teachers and conventional laboratories. This ZIM-SCI study guide presents activities…

Project Chemlab was designed to prepare an "Annotated List of Laboratory Experiments in Chemistry from the Journal of Chemical Education (1957-1979)" and to develop a computer file and program to search for specific types of experiments. Provided in this document are listings (photoreduced copies of printouts) of over 1500 entries…
