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.…

This study was carried out in response to the announcement of the reversal of the ETeMS policy (English in the Teaching of Mathematics and Science) which had been practiced by teachers in Malaysia since 2003. The Ministry of Education took a drastic approach in gradually halting this controversial policy for several related reasons, namely the…

The purpose of this study was to consider the efficacy and popularity of "Virtual Lectures" (text-based, structured electronic courseware with information presented in manageable "chunks", interaction and multimedia) and "e-Lectures" (on-screen synchrony of PowerPoint slides and recorded voice) as alternatives to traditional lectures. We…

Reports on a survey of computer use administered to 400 elementary mathematics or science teachers in South Carolina. Inquiries included: (1) purposes for which used; (2) brands available; (3) recommended software; (4) effects on students; (5) teacher training; and (6) audio or video packages used.

Describes a study that was conducted at the University of South Africa to determine the feasibility and the effectiveness of using computer-aided learning for a distance education chemistry course. Highlights include summative courseware testing; cost effectiveness; student achievement; student attitudes; and an appendix that lists responses from…

In 1980, Wichita State University received a grant to introduce microcomputers as interactive teaching tools in large science classrooms. Through this grant, 18 faculty in 11 departments developed software modules illustrating concepts that are often difficult to teach by usual lecture methods. To determine whether the use of microcomputers in…

Describes the development and evaluation of an interactive videodisc designed for Open University students in a physics course that explores the physical properties of water. The user interface is discussed; software is described; videodisc production is explained; and results of an evaluation of student attitudes from questionnaire responses is…

A study of 60 elementary and secondary math and science teachers who were nominated by their peers as effective microcomputer-using teachers was conducted to describe how peer-nominated teachers use microcomputers instructionally, and how these uses vary as a function of teacher characteristics (e.g., knowledge, attitudes) and other background…

Describes study that investigated teachers' criteria for the use of courseware packages in Dutch junior high school physics classes. The development of a courseware evaluation instrument is described; drill and practice, simulation, and tutorial courseware packages are evaluated; motivating elements are considered; and implications for the design…

This study of patterns of microcomputer-based instruction in elementary and secondary schools had three objectives: (1) to describe how teachers who were nominated by their peers as "unusually successful" in their microcomputer-based mathematics and science teaching use technology for instruction; (2) to describe how these uses vary as a…
