Examines research on a computer-based tool, CASCADE (Computer Assisted Curriculum Analysis, Design and Evaluation), that was developed at the University of Twente (Netherlands) to assist in curriculum development. Discusses electronic performance support systems and the need for increased attention to implementation and impact studies. (Author/LRW)

Discusses knowledge management systems (KMS) and their application to instructional design. Highlights include a history of computing and instructional systems; computer-supported collaborative work environments; object-oriented systems; reusability; a conceptual framework for distributed instructional design; and examples of support tools.…

Describes a set of computerized tools that support the instructional design and evaluation of competency-based training programs. Discusses authentic whole-task practice situations; the 4C/ID* methodology; an evaluation tool that supports the subsequent revision of the competency-based training design; and future plans. (Author/LRW)

Offers a critique of the articles in this issue. Examines the four basic instructional design tools that are described, including tool functions, tool characteristics, and tool evaluation; compares the tools with earlier models; and suggests the need for future instructional design tool research and development.

This study proposes a hierarchical hyper concept map (HHCM) course system which consists of a navigation map, concept maps, and hypermedia documents. Results of testing the HHCM as a course representation showed achievement was greater for students learning from the course represented by HHCM compared with those learning from a linearly…

This study analyzed how students and teachers of one Finnish elementary class participated in and communicated through the Computer Supported Intentional Learning Environment (CSILE) during 1997-1998. The density of the interaction within class, students' participation rates, students' position in the CSILE mediated network of interaction, and the…

In a three-year study, female students from all-female computer science (CS) classes were compared to male and female students from mixed-gender CS classes. Participants were 250 students enrolled in an elective Grade 11 CS course. The study provides some initial empirical evidence supporting the positive effects of all-female classes in CS at the…

Describes an instructional model for teaching abstract data types (ADTs) to high school students. Presents research results regarding students' conceptualizations of ADTs and their strategies of using them in computer science problem solving. To implement the ADTs, "black boxes" were used. (AEF)

Proposes a novel methodology that employs Bayesian network software to assist teachers in efficiently deriving and utilizing the student model of activity performance from Web portfolios online. This system contains Web portfolios that record in detail students' learning activities, peer interaction, and knowledge progress. (AEF)

Discusses the role of microworlds in micro and macro educational systems. Topics include epistemological concepts; educational innovations; mathematics education in elementary schools; microworlds as simplified reality and as mental structure; and a three-stage theory of the development of learning. (LRW)

Reflects on the meaning and evaluation of the microworld idea. Distinguishes between user manipulation and modification at three levels: the interface, superstructural, and platform levels; presents a case study of two eight-year-old girls playing a video game based on Logo; and discusses mathematical learning. (Author/LRW)

Explains TIMA (Tools for Interactive Mathematical Activity), that were designed to provide elementary schools children with contexts in which they could enact mathematical operations. Discusses differences from drill and practice software; provides examples of how the TIMA were used by children to engage in cognitive play; and emphasizes the…

Explores the strategies and interactions of elementary school children in a computer-based microworld related to the concept of length. Included both on and off computer activities that contributed to the collaborative learning environment, a high level of interest, and enthusiasm for mathematical activities. (Author/LRW)

Describes the design principles behind a set of research-based software microworlds included in the "Building Blocks" program, a pre-kindergarten to grade 2 software-based mathematics curriculum. Discusses how to help children extend and mathematize their everyday activities and presents the nine-step design process model used. (Author/LRW)

Proposes a whole-class view of microworld design in which the total ecology of students, technology, and teacher is considered by the decisions and choices of the design. Presents a case study analysis of a secondary school classroom implementation with a geometry microworld and discusses student affect, participation, and the role of educational…
