Collaborative concept mapping, as one of the widely used computer-supported collaborative learning (CSCL) modes, has been used to foster students' meaning making, problem solving, and knowledge construction. Previous empirical research has used varied instructional scaffoldings and has reported different effects of those scaffoldings on…

This study at the University of Guam investigated student teachers' perception and practice of the teacher's role when teaching with computers. The teacher's role was measured as teacher-centeredness and student-centeredness, and results showed a significant difference in computer use although no difference in perception of use.

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…

Examines the impact of contextual factors on teachers' roles and teachers' roles in contributing to the effective use of computer-aided instruction in Singapore's secondary schools. A path modeling approach was adopted whereby factors during different stages of the teaching and learning are examined before the final outcome, the student's learning…

Reports on a case study that led to a model of how teachers use computers in classroom teaching. This model conceptualizes the computer as a teaching resource that helps teachers to develop their teaching strategy, replacing the teachers in their role of managing students' rehearsal of materials and serving as a classroom management tool.

Discusses the systems thinking approach that uses microcomputer-based simulations and modeling to enhance teaching and learning activities in middle school and high school instruction. Particular focus is placed on the Systems Thinking and Curriculum Innovation Network project, part of a longitudinal study managed by Educational Testing Service.…

Describes a time allocation study that was designed to determine how two types of teachers spent their time regarding gender differences in a primary school computer laboratory in Costa Rica. Topics include the sociocultural context of gender roles in Costa Rica, hypothesis testing, and the domination of boys in computer labs. Contains 101…

Discussion of appropriate feedback in an instructional setting focuses on a study of undergraduates learning graphics materials production techniques that investigated whether internal feedback, provided by an expert system, differed in effectiveness from external feedback, provided by an instructor. The effects of each on processing activities…

An experimental study compared the instructional effectiveness of Logo programming, commercially available software designed to aid composition and problem solving, and traditional teaching methods for low socioeconomic status first-grade students. Both software environments enhanced problem solving performance for a novel task, but Logo was most…
