This article introduces "medium-based" design -- an approach to creating "exploratory learning environments" using the method of "extending a medium". First, the characteristics of exploratory learning environments and medium-based design are described and grounded in related work. Particular attention is given to "extending a medium" --…

There is a body of evidence supporting the claim that informal interactions in educational environments have positive effects on learning. In order to increase the opportunities of informal interaction in online courses, an instant messaging tool, called CENTERS, was developed and integrated into online learning environments. This tool provides…

Describes an experimental test conducted with high school students to determine the effect of posting explicit goal structures on problem-solving performance in an intelligent tutoring system for calculus. Related rates word problems are discussed, and student performance in terms of speed and accuracy is analyzed. (Contains 29 references.) (LRW)

In recent years project-based learning (PBL) incorporating online discussions has gradually been applied to courses that focus on writing projects. Past studies have shown that learners in PBL often face the difficulties of not having in-depth data analysis and peer discussions and how teachers design the rules and methods for online discussions…

Examines how systems thinking, simulation, and modeling affect secondary school teachers' classroom processes. Highlights include a two-dimensional matrix to show patterns of adaptation, teacher proficiency with technology, curriculum development, time constraints, teacher training, expertise, accountability, administrative issues, and the…

Articles in this special issue on the theme of cognitive skills acquisition in lifelong learning begins with an analysis of cognitive skills, then moves to various methodologies and approaches for their effective acquisition, and concludes with a specific implementation of computer systems facilitating this acquisition. (AEF)

Discusses concurrent, or parallel, programming languages; explains the design of the MultiLogo programming language; and describes a study of fourth and fifth graders that used MultiLogo to control robotic devices built out of Lego bricks. Three categories of MultiLogo programming bugs are described, and implications for changes in design and…

A novel Web-based Accountability Model (WAM) for assessment and learning in a Teacher Education Program was implemented. The objective is to explain the rationale for the WAM model, how it was implemented as the web-based Education Accountability System (EAS), and the impacts on the organization and the individual. Standards were followed in the…

Between 2001 and 2005 the Universities and Colleges Information Systems Association (UCISA) and the Joint Information Systems Council (JISC) conducted surveys into issues relating to the acquisition, use, management, and support of Virtual Learning Environments (VLEs). A number of other studies provide information on these issues during this…

Achieving student participation, it has been argued, is one of the most important challenges in distance education. This explorative study examines whether a synchronous communication medium, instant messaging (IM), may enable students to participate more actively in online group work. When comparing two groups that adopted IM with two groups that…

Explores the use of a cyberspace technology, i.e., computer conferencing, to support collaborative learning in courses at two Canadian universities. Instructional design for online learning is examined, including course design, learning tasks, group size, and course requirements; problems are identified; and improvements are suggested, including…

Introduces three papers that discuss the design methodology for developing learning systems for cognitive skills acquisition. Provides specific examples of processes that underlie the acquisition of cognitive skills. Confirms that through the embrace of lifelong learning, cognitive skills-based learning environments are finding a more prominent…

Describes an intelligent tutoring system designed to help students remedy misconceptions of physics concepts based on a teaching strategy called bridging analogies. Highlights include tutoring strategies; misconceptions in science education; the example situation network; confidence checking; formative evaluation with college students, including…

The article presents a reusable online support system, in which an open-ended learning environment is created to scaffold complex, real-world problem solving activities. The major learning components of the system are specifically described, and the internal interactions between different components within the system and the external interactions…

The article focuses on the use of information and communication technology (ICT) for strengthening and transforming university practice in line with the social and technological conditions of the new ideas for "interactive" universities. The purpose is to use ICT as a change-agent in order to establish new practices--new pedagogical…
