The technological revolution and transformation in schools transforms the practices of literacy and poses tremendous challenges to literacy educators and researchers to rethink their basic tenets, to integrate technology and literacy in creative and productive ways. The aims of this study are to examine the characteristics of literacy practices in…

It is widely accepted that inquiry-based curriculum programs have positive effects on cognitive achievement, process skills, and attitudes toward science (NRC 2000). Science teachers seek engaging, effective, and inquiry-based activities that are standards-aligned and convenient to implement in their classrooms. For many years, the web has…

This study investigated students' understanding of a virtual infectious disease in relation to their understanding of natural infectious diseases. Two sixth-grade classrooms of students between the ages of 10 and 12 (46 students) took part in a participatory simulation of a virtual infectious disease, which was integrated into their science…

An exercise to compute LLE data is presented to illustrate the problems that can arise when the isoactivity equilibrium condition is used in the LLE calculations. A much more efficient condition is obtained when isoactivity is combined with the common tangent line criterion, avoiding false solutions that correspond with very low values of the…

In this paper, we describe a pedagogical approach to elastic body movement based on measurements of the contact times between a metallic rod and small bodies colliding with it and on modelling of the experimental results by using a microcomputer-based laboratory and simulation tools. The experiments and modelling activities have been built in the…

Although one role of computers in science education is to help students learn specific science concepts, computers are especially intriguing as a vehicle for fostering the development of epistemological knowledge about the nature of scientific knowledge--what it means to "know" in a scientific sense (diSessa, 1985). In this vein, the…

Since 1983, the Maryland University Project in Physics and Educational Technology (M.U.P.P.E.T.) has been investigating the implication of including student programming in an introductory physics course for physics majors. Many significant changes can result. One can rearrange some content to be more physically appropriate, include more realistic…

Examines what fourth-grade students learned by using computer-based tools intended to help them understand sound and music. Findings provide critical information for future instruction with the goal of supporting learning about sound and music from such tools. They also indicate the need for more studies examining learning from computer-based…

Describes some elementary science and technology programs and what can be learned about them from the Internet. Discusses what is available from each. (Author/NB)

Discusses using computer technology to teach science. Demonstrates how computer technology can enhance science learning at different levels. Concludes that the use of technology helps students develop skills for the future. (NB)

Describes a method for teaching electronic structure and its relevance to chemical phenomena that relies on computer-generated three-dimensional models of electron density distributions. Discusses the quantum mechanical background needed and presents ways of using models of electronic ground states to teach electronic structure, bonding concepts,…

Describes an experiment to demonstrate a simple method for measuring fungus growth by monitoring the effect of temperature on the growth of Trichoderma viride. Among the advantages that this experimental model provides is introducing students to the importance of using the computer as a scientific tool for analyzing and presenting data. (AIM)

Describes a teaching method using computer probeware to enhance students' laboratory experiences. Discusses the role of computer probeware in the science classroom, how probeware affects learning, and how it affects efficiency. (KHR)

Presents a program that provides a structured listing of BASIC computer programs in a text file. Indents for-next loops for better appearance and easier understanding. Lists program and provides for several versions of BASIC. (MVL)

Discusses the use of a spreadsheet program to vary the parameters in multiloop circuit problems. Enables students to better understand how the elements in a multiloop circuit determine the current by allowing them to see the results of the changes immediately. (JRH)
