Describes research project being implemented in the United Kingdom that has been developed to examine the process of change in secondary school students' conceptual understandings in the physical sciences. Models of conceptual change are described, the role of computer based activities in promoting conceptual change is discussed, and software…

Describes the basic mechanisms of the SimQuest, an authoring system for designing/creating simulation-based learning environments. The functionality authors have in providing the learner with guidance and experiences on how authors use opportunities and learners employ the cognitive support are reported.(Author)

While simulations have widely been used to facilitate conceptual change in learning science, results indicate that significant disparity or gap between students' prior conceptions and scientific conceptions still exists. To bridge the gap, we argue that the applications of computer simulation in science education should be broadened to enable…

The purpose of this study was to investigate value of combining Real Experimentation (RE) with Virtual Experimentation (VE) with respect to changes in students' conceptual understanding of electric circuits. To achieve this, a pre-post comparison study design was used that involved 88 undergraduate students. The participants were randomly assigned…

Reports an investigation into pupil-talk in small groups during a computer simulation. The role of language as a communication and understanding aid is considered, along with the microcomputer's potential as a stimulus to and generator of discussion. The contents of participants' conversations, at and away from the microcomputer, are analyzed.…

Applies principles of constructivism and virtual reality (VR) to computer-aided design (CAD) curriculum, particularly engineering, by integrating network, VR and CAD technologies into a Web-based learning environment that expands traditional two-dimensional computer graphics into a three-dimensional real-time simulation that enhances user…

Discusses the nature and function of mental models, explains tools for exploratory and expressive learning, and describes a research program to be conducted in the United Kingdom for 10- to 16-year-olds that is designed to explore characteristics of students' mental models. Highlights include knowledge domains; software, including simulations; and…

Evaluates the use and efficiency of two computer learning tools for basic virology. "VIROLAB" is a simulation of a biology laboratory which also includes a hypertext providing learners with some knowledge on virology. The Hypertext is a version of the hypertext in VIROLAB. The study examined which of the two was most efficient for knowledge…

Describes a computer simulation game and database package, "Palestine in the First Century," developed for upper primary and secondary school religious education in Scotland and designed for use on a microcomputer with a printer. The effect of this type of software on the role of teachers and students is considered. (Author/LRW)

Discussion of the evaluation of courseware focuses on a study conducted to evaluate the Health and Fitness Assessment (HAFA) program, which was designed to elicit problem solving skills to assess health and fitness parameters and develop exercise prescriptions. Protocol analysis is described and the analysis of interpretive statements is…

Describes software that was designed in the United Kingdom to promote conceptual change in secondary school students studying mechanics. Direct Manipulation of Mechanical Microworlds, an interactive computer simulation, and VARILAB, a computer-based language for modelling systems, are explained; and two studies that will evaluate the effectiveness…

Describes a pilot study aimed at exploring the possibility of introducing simulation-based homework into junior high school ninth grade science classes studying electric circuits. Analyzes students' views in relation to their prior computer experience and their achievement, and discusses results from questionnaires and interviews that show…

This study investigated the verbal interactions of fifth grade students within groups when using simulation and word processing software. Students were grouped according to ability, and conversations were analyzed, which found the largest proportion of student talk was cognitively oriented, predominantly in directing and reporting language; group…

Describes a study designed to assess the effectiveness of 2 science simulation programs for 11- and 12-year-olds in a developing country (Guyana). Computer-assisted learning (CAL) results are compared with results from written assignments, effect size is discussed, gender differences are examined, and ability levels are considered. (14 references)…

Discussion of teaching complex knowledge domains through exploration highlights two experiments that investigated the educational value of a Dutch computer simulation program which models the relationship between erosion and agriculture in a developing country as part of the secondary school geography curriculum. Learning by doing versus learning…
