The case study focuses on the interactional mechanisms through which online collaborative teams co-construct a shared understanding of an analytical geometry problem by using dynamic geometry representations. The collaborative study consisted of an assignment on which the learners worked together in groups to solve a ship navigation problem as…

This study compared the effectiveness of computer-mediated instruction (CMI) and teacher-mediated instruction (TMI) on the word problem-solving performance of students struggling in mathematics. Both conditions integrated cognitive modeling that focused on the problem structure using visual representations with critical instructional elements…

This article presents key steps in the design and analysis of a computer based problem-solving assessment featuring interactive tasks. The purpose of the assessment is to support targeted instruction for students by diagnosing strengths and weaknesses at different stages of problem-solving. The first focus of this article is the task piloting…

A frequent task in educational settings is to assign students to groups based on stated preferences for some projects or topics. This paper introduces a web-based tool supporting both the work flow of collecting student data and the group formation. The latter is based on finding optimal solutions to suitable mathematical assignment problems,…

This paper addresses issues of using computer technology to support in-classroom teaching and learning regarding one of the most frequent problems in such scenarios: the students' attention. First, it presents the distraction and focus of attention problems that arise while using computer technology with off-the-shelf software for supporting…

The topics of computer-assisted instruction, computer-augmented problem solving, and computer-managed instruction are discussed. In the field of computer-assisted instruction, uses of the computer for drill and practice, tutorial purposes, and simulation are examined. (Author/JN)

The computer has not yet reached its full potential in the secondary school. Besides instructional usage, present usages of the computer include computer-managed instruction, acquisition of basic skills, teaching computer literacy, evaluating occupational information, and providing data about colleges and universities. (Author/JN)

Defines computer literacy, reviews the potential applications of computers as educational aids, and discusses the major areas of competence required of teachers who will deal with computers in an instructional setting--either as users or as programers. (JL)

A proposal to replace plane geometry with computer programming in the standard high-school mathematics curriculum is presented. (MP)

Examines the presence of two factors, cooperative learning training and problem-solving computer-based instruction (CBI), in 23 studies which compared cooperative CBI (C-CBI) and individual CBI (I-CBI). Results provide more evidence that cooperative learning and problem-solving CBIs are important factors in increasing achievement, group…

The present study investigated the effects of question prompts in scaffolding novice instructional designers solving ill-structured, instructional design problems in a Web-based learning environment. The effects of question prompts were studied under different prompting conditions (Question-Elaboration vs. Question-Guidance), taking into…

In this study, we examined the use of cognitive tools provided in a problem-based hypermedia learning environment for sixth graders. Purposes were to understand how the built-in tools were used, and if tool use was associated with different problem-solving stages. Results showed that tools supporting cognitive processing and sharing cognitive load…

Today's educational software has transcended original drill and practice functions to provide enjoyable learning experiences through simulation, tutorial, and special education programs that develop reasoning and problem-solving skills. Teacher and administrator effectiveness can be enhanced by lesson design, scheduling, attendance, grade…

Presents reviews of three software packages. These are "Ant Farm," a game of problem solving using guess and check or trial and error; "Learning Place Value"; and a set of three utility programs--"Mastering Math: Diagnostic System,""Mastering Math: Worksheet Generator," and "Mastering Math: Management System." (PK)

Presents results of two long-term research projects: (1) shows that early work experience influences an engineer's performance even more than high grades, (2) lack of organizational coordination rather than the lack of innovative ideas inhibits implementation of computer-based technologies. Lists methods for implementing computer-based…
