Among three levels of chemical representation, the sub-microscopic level is the most difficult to learn by students. To solve the problem, it is assumed that the concept of the discontinuous nature of matter or particle concept should be mastered initially by students before they learn sub-microscopic representations of further chemical phenomena.…

OpenCourseWare (OCW) has received increasing attention over the past few years in higher education. These courses provide appealing opportunities to view classes taught in well-established universities worldwide. The current study aims to examine how OCW lectures can serve as authentic learning materials to facilitate vocabulary acquisition for…

The purpose of this study is to examine the difference in effectiveness between two on-line scientific learning programs--one with an argumentation component and one without an argumentation component--on students' scientific argumentation ability and conceptual change. A quasi-experimental design was used in this study. Two classes of 8th grade…

In order to facilitate senior primary school students in Hong Kong to engage in learning by observation of the phenomena related to electrical circuits, a design of a specific courseware system, of which the interactive human-machine interface was created with the use of an open-source software called the LabVNC, for conducting online…

An evaluation of the Mathematics and Computer Assisted Remedial Teaching (MASCART) project in the Pre-Entry Science Course (PESC) at the University of Botswana focused on two questions: (1) Considering the conditions for successful implementation highlighted in the literature, has the implementation of computers in the PESC department been such…

Describes a study of second graders that was conducted to investigate the use of microcomputer-based software to teach line graph production and interpretation. Abstract concepts between time and distance relationships are discussed, and transfer of skills to other types of graphs on paper are examined. (LRW)

Describes a study of eighth-grade students that investigated the impact of computer simulations on students' ability to generalize scientific concepts from classroom to naturally occurring problems. A curriculum for teaching thermodynamics that was reformulated to emphasize integration of understanding is described, and student reactions are…

Describes a study of high school students that investigated the impact of computer-assisted learning (CAL) integrated with classroom-laboratory instruction versus classroom-laboratory work alone on students' achievement and mastery of science process skills in a microbiology course. Posttest scores are compared and the curriculum integration of…

The purpose of this study was to investigate the effect of implementing cooperative learning and objectives with computer-based instruction (CBI). Subjects were 125 fifth and sixth grade students. Cooperative dyads and individuals worked through a CBI earth science program that contained either instructional objectives, advance organizers, or no…

The EuroMET (European Meteorological Education and Training) project was created to address the education and training needs of professional meteorologists and students in tertiary education throughout Europe and more widely. Two courses, each modular in format, have been developed for the World Wide Web. The courses have been evaluated at three…

This study investigated the use of tools and design features as employed in a problem-based learning (PBL) environment and their effectiveness on seventh grade students' learning of science concepts. Specifically, the study examined: (1) the effect of the computer-supported PBL environment on the achievement of middle school students; (2) the…
