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…

AHA! is a simple Web-based adaptive hypermedia system. Because of this simplicity it has been studied and experimented with in several research groups. This paper identifies shortcomings in AHA! and presents AHA! version 2.0 which tries to overcome the known problems with AHA! while maintaining its biggest asset: simplicity. The paper illustrates…

Guidelines are presented for the development of computer-based instructional materials. Steps in courseware development defined by M. D. Roblyer (1988) include: (1) instructional design; (2) preprograming development; and (3) programing. The emphasis is on instructional design, the most time-consuming part of the task. Preprograming development…

The program demonstrated in this paper, "The Classroom Behavior Record: School Version," is an alternative approach for training personnel in observational skills, designed for educators and health care professionals. The purpose of the program is to provide efficient and effective training in a flexible, learner-centered, hypermedia format. The…

Novices in programming face many problems affecting their learning process and programming success. Learning to program includes using the programming environment, learning a programming language's syntax and semantics, understanding a problem and translating it into an executable plan, developing algorithms and programs, and testing and debugging…

This paper introduces and analyzes problems and issues in the design and use of cognitive tools in open, user-centered learning environments. It introduces a classification scheme for tool functions, and showcases several tools in a current educational hypermedia research and development effort. Information-seeking, information-presentation,…

Researchers have claimed that while educational computer software does not necessarily improve students' academic performance, it does provide for students a more interesting and motivational environment for learning. It naturally fits in the context of students' learning since it can deliver nonstop actions, realistic sounds and vivid colors to…

The Collaboratory Notebook, developed as part of the Learning Through Collaborative Visualization Project (CoVis), is a networked, multimedia knowledge-building environment which has been designed to help students, teachers and scientists share inquiry over the boundaries of time and space. CoVis is an attempt to change the way that science is…

In research and development it is not unusual to find the resources driving the instruction; this approach can be modified to a more acceptable one if the new technology is applied in such a way as to integrate sound instructional methods. Research and development personnel of the University of Victoria (Canada) Language Center often initiate…

Current literature pertaining to multimedia programs is reviewed and discussed as it relates to the design and development of instructional programs. Most of the literature reviewed covers the last 4 years. Major areas discussed include: (1) instructional (instructional strategies and cooperative learning); (2) branching (navigation and learner…

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…

This paper presents a model for designing computer-based simulation environments within a constructivist framework for the K-12 school setting. The following primary criteria for the development of simulations are proposed: (1) the problem needs to be authentic; (2) the cognitive demand in learning should be authentic; (3) scaffolding supports a…

A difficult task in creating rich, exploratory interactive learning environments is building an environment that is truly engaging. Engagement can be defined as the nexus of intrinsic knowledge and/or interest and external stimuli that promote the initial interest in, and continued use of a computer-based learning environment. Complete and total…

This paper examines research studies of learner control in computer-based instruction (CBI) from 1987-1997. The review evaluates predictions and conclusions from previous literature reviews, in light of current research, and discusses the implications of recent findings for instructional development. Findings suggest that the positions that…

This paper describes an alternative delivery approach for training personnel in observation skills using interactive multimedia technology. The "Classroom Behavior Record (CBR) Observation Training Program," includes three videodiscs that contain video and audio scenes of children in classrooms/playgroups and instructional narrations.…
