This project originated with the desire to offer general biology students a laboratory experience which emphasizes scientific thinking rather than a review of lecture content. To create investigative laboratories without many of the practical problems of their implementation, this project uses a combination of "methods modules" for…

This volume contains the papers presented at the fifth International Conference on the Learning Sciences (formerly the International Conference on Artificial Intelligence and Education). As the change in name signifies, a strong effort has been made to open the conference to a broader audience, including educational and cognitive psychologists…

This publication contains a selection of science education research papers, beginning with an overview of trends in science education cognitive developmental research and theory in the United Kingdom. Papers that follow focus on developments in studies of thinking and reasoning, including work on concept mapping and conceptual change. Closely…

Density is the first intensive physical quantity students encounter that can be understood in terms of an underlying model, the particulate theory of matter. Learning about density provides students with explanations for a range of phenomena such as sinking and floating, and changes of state. Teachers report, however, that density is a difficult…

Describes the effects of one computer program used in a nonmajors biology course to provide a model for implementing and validating the use of software programs that incorporate tutorials with laboratory simulations. (Contains 27 references.) (MDH)

As part of a series of documents describing assessment of student learning in various curriculum areas in South Carolina, this document reviews the assessment of student learning in the science classroom. The report begins with a discussion of effective science learning, and outlines the knowledge, skills, and dispositions that encompass science…

This paper presents the results of three years of development and evaluation of a CD-ROM/Web hybrid simulation known as Brownfield Action for an introductory environmental science course at an independent college for women in the northeastern United States. Brownfield Action is a simulation that provides a learning environment for developing the…

This study investigated the types of tactics and strategies students used in working with computer simulations and examined if the skills acquired when using the computer simulation could be applied in other settings. Sixth grade students (N=50) from three different schools participated in the study and were observed over a period of six weeks.…

Reviews seven computer software programs that can be used in science education programs. Describes courseware which deals with muscles and bones, terminology, classifying animals without backbones, molecular structures, drugs, genetics, and shaping the earth's surface. (TW)

Examines 11 microcomputer simulations dealing with politics, the presidency, and campaign issues. Topics covered include simulating the campaign; facts, history, and math of the presidency; a database approach; and voting. Lists positive attributes about each program. (MVL)

Decades of research have provided evidence that food irradiation is a safe technology that can decrease the incidence of foodborne diseases; however, adoption of this technology has been slow. The purpose of our study was to qualitatively explore the effectiveness of various components of a professional development training on family and consumer…

This booklet summarizes the science chapter from the "Handbook of Research on Improving Student Achievement," a report sponsored by the Alliance for Curriculum Reform and also published by the Educational Research Service. The handbook is based on the idea that efforts to improve instruction must focus on the existing knowledge base on…

This reivew of research examines the effectiveness of computer-assisted-instruction (CAI) in raising the achievement levels of students at various levels and areas of instruction. The review studies four main categories of material written about CAI: (1) opinion papers; (2) descriptions of available hardware; (3) reports evaluating the…

The Water and Molecular Networks (WAMNet) Project uses graduate student written Reduced Instruction Set Computing (RISC) computer simulations of the molecular structure of water to assist high school students learn about the nature of water. This study examined: (1) preconceptions concerning the molecular structure of water common among high…

The conference proceedings include the following papers: (1) The Arts Metaverse in Open Croquet: Exploring an Open Source 3-D Online Digital World (Ulrich Rauch and Tim Wang); (2) Beyond World of Warcraft: the Universe of MMOGs (Ruben R. Puentedura); (3) ClevelandPlus in Second Life (Wendy Shapiro, Lev Gonick, and Sue Shick); (4) Folksemantic:…
