If learners are to engage in science inquiry, they need significant support, or scaffolding, to help them mindfully do the cognitive science tasks that are just out of their reach. One approach for supporting learners is to design computational tools that incorporate scaffolding features to make new practices accessible and visible so learners can…

Describes the Hypertutor Model, a message design framework for interactive instructional systems that emphasizes learner control, presentation, practice, feedback, and learning resources. Problems with software designed for computer assisted instruction are examined; hypertutor systems are discussed; and MegaMentor, a hypertutor system at the…

This paper describes a 4-month-long experiment in computer-based learning called Instructional Software Design and presents aspects of the software evaluation. Results included greater mastery of LOGO and fractions by the experimental class than for either control class and greater acquisition of metacognitive skills. (Author/CW)

Development of online courses requires the use of appropriate educational philosophies that discourage rote learning and passive transfer of information from teacher to learner. This paper reports on the development, use and evaluation of two second year Biology online software packages used by students in constructivist environments. The courses…

Investigates the effects of studying alone or in cooperative-learning groups on the performance of high and low achievers, using either learner- or program-controlled computer-based instruction. Participants were 92 sixth-grade students. Results suggest that cooperative learning provides beneficial effects, and imply a need for software designers…

Examines the learning benefits of a learner-as-designer environment simulating a real-world multimedia production house and its impact on at-risk high school students. Students showed a significant growth in their value of intrinsic goals and achieved several critical design skills. The experience provided many students, who could not otherwise…
