Describes the development, use, and evaluation of the "Osmosis Program" as a teaching tool to elicit and challenge college students' understanding about diffusion and osmosis. Results showed students using the program performed better on a diffusion and osmosis assessment test than students not using the program. (Author/MKR)

Describes the development of Casebook of Project Practices (CaPPs) to help teachers learn a constructivist approach to science teaching--project-based science. Presents a study using CaPPs in a teacher development institute. Implications concern backgrounds teachers bring to the use of multimedia and how these backgrounds influence how they use…

The Baldufa project at the Polytechnic University of Catalonia (Spain) is designed to assist physics teachers and students with teaching and learning activities. It has established Web and electronic-mail servers, is creating physics-related documents to be shared, is elaborating teaching strategies for using stored information, and offers…

Describes how to use the computer algebra system (CAS) Mathematica to analyze projectile motion with and without air resistance. These experiments result in several conjectures leading to theorems. (Contains 17 references.) (Author/ASK)

Describes the Mars Millennium Project that challenges elementary and secondary school students across the nation to design communities on Mars. Lists the sponsoring organizations, explains how to participate in the project, and suggests appropriate books and Web sites. (LRW)

Reviews 30 weather-related Web sites, including readability level, under the subjects of air pressure, bad meteorology, clouds, droughts, floods, hurricanes, lightning, seasons, temperature, thunderstorms, tornadoes, water cycle, weather instruments, weather on other planets, and wind. (LRW)

Presents guidelines for equipping physics labs with components from each of four technology-use categories: (1) computer interfacing; (2) modeling; (3) simulations; and (4) research-reference-presentation. Includes references to useful websites discussing educational technology. (WRM)

The use of molecular dynamics and Monte Carlo methods has provided efficient means to stimulate the behavior of molecular liquids and solutions. A Monte Carlo simulation program is used to compute the structure of liquid water and of water as a solvent to Na(super +), Cl(super -), and Ar on a personal computer to show that it is easily feasible to…

A pendulum "engine" with dynamic parameters can be created and pendulum functions manipulated and analyzed using interactive elements in Flash. The effects of changing the damping (convergence) properties, initial release angle and initial velocity conditions can be explored. The motions then can be digitized using the Flash Digitizer 1.1,…

This study has been carried out in order to determine the effect of computer animations in teaching acid and base topics in science and technology courses on the academic success of the primary school students and the opinions of students related to teaching with the animations. This research was conducted by the participation of 55 students from…

The WebQuest is a four-step process integrated at appropriate points in the Animal Studies unit. Through the WebQuest, students create a series of habitat maps that build on the knowledge gained from conducting the various activities of the unit. The quest concludes with an evaluation using the WebQuest rubric and an oral presentation of a final…

A series of interviews was conducted with NSW primary teachers, working within a rural context, to obtain their views about the benefits of using ICT in the delivery of the primary curriculum and specifically primary science. The interviews were also used to determine how these teachers were using ICT and if they had any specific training needs.…

Francis Bacon began defining scientific methodology in the early 17th century, and secondary school science classes began to implement science labs in the mid-19th century. By the early 20th century, leading educators were suggesting that science labs be used to develop scientific thinking habits in young students, and at the beginning of the 21st…

Explains a study that proposed and tested how graphical representations influence what is learned and recalled from text. Results highlighted the importance of graph-focusing strategies for text learning and support the creative use of interactive computer presentation. (ML)

Discusses general statistical methods which could be employed to develop homework problems and laboratory exercises. Methods emphasize experimental design and the effects of uncertainties on inferences drawn from experimental data. (CW)
