The aim of this study was to determine the effects of problem-based active learning in science education on students' academic achievement and concept learning. In the study, both quantitative and qualitative research methods were utilized. Quantitative data were obtained via the pre/post-test, treatment-control groups test model. Qualitative data…

The accelerating rate of data generation and resulting publications are taxing the ability of scientific investigators to stay current with the emerging literature. This problem, acute in science, is not uncommon in other areas. New approaches to managing this explosion of information are needed. While it is only possible to read one paper or…

This article is the first of a two-part review of research on children's and adults understanding of gravity and on how best to teach gravity concepts to students and teachers. This first article concerns free fall--how and why objects fall when they are dropped. The review begins with a brief historical sketch of how these ideas were developed in…

Researchers in the field of bioinformatics have developed a number of analytical programs and databases that are increasingly important for advancing biological research. Because bioinformatics programs are used to analyze, visualize, and/or compare biological data, it is likely that the use of these programs will have a positive impact on biology…

This paper reports on the results of an action research to explore the effectiveness of using cooperative learning strategies on students' academic achievement, their understanding of physics concepts and their motivation to learn in the physics classroom. The study involved a secondary four express physics class of 41 students in a neighbourhood…

This book is a comprehensive guide to 100 popular research topics for high school students. Each guide, which can be photocopied, will help the student to locate print and nonprint information about the topic, narrow the scope of the paper, and find related topics. In addition to serving as a map to library resources, each guide acts as an outline…

This study explored the multiple effects of "professionalization" discourse on the creation of a new early childhood teacher certification program at the University of Wisconsin-Madison. The study explored two questions: How is the influence of professional ideology on the construction of the program linked to university prestige and…

This resource for teachers of elementary age students provides a foundation for building a life-long interest in the U.S. space program. It begins with a basic understanding of man's attempt to conquer the air, then moves on to how we expanded into near-Earth space for our benefit. Students learn, through hands-on experiences, from projects…

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 students' thinking regarding their views on particles and particle…

Introduction: This study sought to answer three questions: 1) Would the level of domain knowledge significantly affect the user's search behaviour? 2) Would the level of domain knowledge significantly affect search effectiveness, and 3) What would be the relationship between search behaviour and search effectiveness? Method: Participants were…

This document reports the state of science achievement of Japanese students based on the Second International Science study conducted in 1983-84. Results are compared to the first study conducted in 1970. The target populations, samples, and structure of the second study are described. Test results including score distribution and high and low…

Major concepts can help create thinking frameworks that are powerful enough to make additional input more meaningful. As a result, the content is richer, more diverse, and more widely applicable. This set of concept papers was produced because concepts are not uniformly understood by practitioners. Each is designed to introduce a concept and to…

These item specifications were developed as a part of the Arkansas "Minimum Performance Testing Program" (MPT). There is one item specification for each instructional objective included in the MPT. The purpose of an item specification is to provide an overview of the general content and format of test items used to measure an…

The purpose of this document is to provide a framework for school districts to use in the development of K-12 science curricula. The framework focuses on those ideas, skills, and attitudes that have the greatest educational significance for enabling the achievement of scientific literacy by all students. The scope of the Arizona Science Essential…

This study examined the role played by particular intellectual and physical environments on concept formation, focusing on conceptions concerning heat in a group of non-western subjects living in the interior of southern Africa (N. Sotho and Tswana peoples). In addition, these conceptions were examined in three contexts of the subjects' cultural…
