Discusses how students learn to model in scientific contexts. Highlights include current research in science education; a computer-based simulation of a student learning to model; an example of a physics task; collaboration with another student; a dialog mechanism; and external representations. (LRW)

Discusses instructional design and the integration of computer-assisted learning (CAL) into corporate training. Topics include the social context of learning in models of instructional design, and CAL as a substitute for other instructional media, as an enrichment, and as an organizational innovation. (LRW)

Discusses recent advances in cognitive theory and the design of computer-based instruction and suggests implications for the design of authoring tools and tutoring system shells. Highlights include the design of courseware; advanced organizers; knowledge representation; design evaluation; models of knowledge; models of errors; and models of…

Describes a new synchronous collaborative environment that combines interactive learning and Group Support Systems for computer-mediated collaboration. Illustrates its potential to improve critical thinking, problem solving, and communication skills, and describes how teachers' roles are changed. (Author/LRW)

Types of learning with a strong emphasis on the responsibility of the learner (such as discovery learning) are gaining popularity over traditional forms of (expository) instruction. Discovery learning distinguishes itself by the central role of learning processes such as hypothesis generation (induction), experiment design, and data…

Empirical studies that focus on the impact of three-dimensional (3D) visualizations on learning are to date rare and inconsistent. According to the ability-as-enhancer hypothesis, high spatial ability learners should benefit particularly as they have enough cognitive capacity left for mental model construction. In contrast, the…

Whereas the penetration of mobile phones in Asian countries keeps climbing, little research has explored the application of the short message service (SMS) in second language learning. This study aims to examine the effectiveness of SMS vocabulary lessons of limited lexical information on the small screens of mobile phones. Thirty high school…

Discusses online help systems in application software design and describes two experiments in which adult computer novices learned to use experimental graphics software by task-based exploration. Topics include operative help; function-oriented help; effects on learning performance; schemata; mental models; and implications for the design of…

We describe an iteratively designed sequence of activities involving the modelling of one-dimensional collisions between moving objects based on programming in ToonTalk. Students aged 13-14 years in two settings (London and Cyprus) investigated a number of collision situations, classified into six classes based on the relative velocities and…

Proposes a Web-based collaborative inquiry learning system and describes a study of undergraduates at the National Taiwan Normal University based on a model system that investigated students' learning processes. Discusses the use of concept maps to anchor and represent knowledge during the inquiry process. (Author/LRW)

Discussion of network-based learning focuses on a survey of computer systems for distributed and distance learning. Both Web-based systems and non-Web-based systems are reviewed in order to highlight some of the major trends of past projects and to suggest ways in which progress may be made in the future. (Contains 92 references.) (Author/LRW)

Discusses a concept used at the University of Twente based on increased flexibility in learning options and the active student in which there are assignments submitted and monitored via a Web-based course management system. Outlines conceptual aspects of feedback as part of the assessment process, particularly feedback supported by a Web-based…

Examines relations between the features of discovery simulations, the learning processes elicited, the knowledge that results, and the methods used to measure the acquired knowledge. Discusses intuitive knowledge and describes a study of post-secondary students that investigated the instructional effectiveness of discovery simulations in physics.…

Four real-time visual feedback computer tools for singing lessons (Singad, Albert, Sing & See, and WinSINGAD), and the research carried out to evaluate the usefulness of these systems are reviewed in this article. We report on the development of user-functions and the usability of these computer-assisted learning tools. Both quantitative and…

Discusses difficulties of learning and teaching science at the secondary school level. Highlights include the nature of science concepts; multilevel thought; the use of scientific experiments; language problems; students' learning processes; and an information processing model that can be used to guide thinking and research in this area. (10…
