This note describes an inexpensive means for making high resolution analog voltage measurements using the parallel printer port of a standard IBM PC or compatible. (PR)

Addresses some basic aspects of Archimedes' law. Focus is on potential energy relationships so as to elucidate some common misunderstandings and to facilitate making bridges with other physical topics. A spreadsheet model is used as a simulation tool. (Author/NB)

Uses multimedia to teach geology to fourth grade students. Explains the HyperStudio project and discusses students' reflections on this project. (YDS)

Investigates the effects of a constructivist versus objectivist learning environment on college students' conceptual change using a computer simulation of the human cardiovascular system as an instructional tool. Contains 33 references. (DDR)

Explains how to use digital cameras and related basic equipment during indoor and outdoor activities. Uses digital imaging in general botany class to identify unknown fungus samples. Explains how to select a digital camera and other necessary equipment. (YDS)

Discusses student and teacher perceptions of a new development in the use of the predict-observe-explain (POE) strategy. This development involves the incorporation of POE tasks into a multimedia computer program that uses real-life, digital video clips of difficult, expensive, time consuming, or dangerous scenarios as stimuli for these tasks.…

Presents the achievements of a program at a research and development institute in Israel where researchers in biology, biotechnology, agriculture, and chemistry supervised talented high-school students in performing research work. Reports that an important part of the program is to familiarize students with the Internet and related technology…

Describes a study of the effectiveness of computer-simulation programs in enhancing biology students' familiarity with ecological modeling and concepts. Finds that computer simulations improved student comprehension of ecological processes expressed in mathematical form, but did not allow a full understanding of ecological concepts. Contains 28…

Describes three websites that feature resources for science teachers, students, and department heads. The first allows teachers to design their own online worksheets, the second contains a collection of science-related images, and the third focuses on issues related to the running, organization, and management of science departments. (WRM)

Describes a simple 16-item instrument, the Propositional Logic Test (PLT), that is based on Piagetian theory and a study that explored the use of the PLT in diagnosing student misunderstandings. Analysis of individual student responses revealed a number of systematic errors in interpreting the logical operations in the PLT items. (Contains 23…

Focuses on projects funded by the National Science Foundation that illustrate the potential of computers and telecommunications to convey higher-order skills and knowledge. Discusses two projects, ScienceWare and Learning though Collaborative Visualization, as examples of knowledge-networking. Describes three other projects that are centered on…

Addresses the Science Education Enhancement and Development (SEED) project, providing a brief summary of the resources produced within the four main areas of SEED: (1) fieldwork; (2) laboratory work; (3) computer-aided learning and assessment; and (4) employer links. (CMK)

Theorizes relationships between gender, education, and computing, exploring education's role in the continued ideological reproduction of computing and technology as masculine domains. Critiques technological determinism and the sociology of science and postmodernist analyses of technology for reducing technology to the social. Brings together…

Describes how computer technology, specifically the use of a multimedia CD-ROM, was integrated into a microbiology curriculum as part of the transition from focusing on facts to fostering learning for understanding. (Contains 30 references.) (Author/YDS)

The notion of scaffolding learners to help them succeed in solving problems otherwise too difficult for them is an important idea that has extended into the design of scaffolded software tools for learners. However, although there is a growing body of work on scaffolded tools, scaffold design, and the impact of scaffolding, the field has not yet…
