This study examined preservice teachers' problem-solving skills through the use of an online video case study. Eighty preservice teachers participated in the study with a three-level video presentation by a two-grade-level between-subjects factorial design. The study incorporates a content analysis framework to examine both the components and the…

This research investigates the role of representational guidance by comparing the effects of two different representational tools. We used a design with two different groups defined by the type of argumentative diagram students co-constructed while working in a computer-supported collaborative learning (CSCL) environment. The Graphical Debate-tool…

A classification system that was developed for the use of agent-based models was applied to strategies used by school-aged students to interrogate an agent-based model and a system dynamics model. These were compared, and relationships between learning outcomes and the strategies used were also analysed. It was found that the classification system…

The purpose of this study was to investigate the results of using computer-assisted instruction to teach basic English grammar material in a senior high school English class. Two experimental groups (one male and one female) consisting of 51 students received computer-assisted instruction as part of the method of instruction, while the control…

Reports results of two studies that compared the introduction of procedural (exemplified by Pascal) and declarative (exemplified by Prolog) programing languages to Italian secondary school students. Discussion covers learning approaches and problems, mental models, programing techniques, programing environments, and educational applications. (27…

Little or no improvement in achievement with CAI for military training has been reported. However, the benefit of CAI for military training is student time savings for equal, but not increased, levels of effectiveness. (MBR)

Reports on a 1999 study that investigated student and teacher perceptions regarding the use of portable computers in a Western Australia secondary school. Compares results with a 1995 study and discusses the need for professional development, support for the development of student computer-related skills, and curriculum changes towards more…

Describes a study that used meta-analysis to compare the academic achievement during a 12-year period of secondary students who were instructed through traditional methods, traditional methods supplemented with computer-assisted instruction (CAI), or CAI alone. Results were compared with earlier research and indicate that the effect of CAI on…

Describes a study conducted with eleventh graders that compared the effects of computer-based instruction (CBI) and print-based instruction (PBI) on motivation, continuing motivation, and content recall. Use of the Instructional Materials Motivation Survey (IMMS) is explained, and the findings, which indicate the superiority of CBI, are discussed.…

Investigated the effects of email conversations between teachers and students on learning graphing in ninth grade classrooms. Compares students who used software with students who used software with email, and discusses results which showed email use led to better performance on graph interpretation and construction and on students' ability to…

A comparison of the effectiveness of different ways to organize instructional materials and different strategies for error feedback used the computer as a research tool and took as subjects first-year junior high school Spanish students, who were randomly assigned to experimental and control groups. To investigate materials organization, computer…

The purpose of this study was to develop and evaluate a series of simulation dialogs utilizing certain computer capabilities. The series of simulations produced in the study parallel the fundamental, inductive experiments developed by the Physical Science Study Committee (PSSC) through which students generalize Newton's Second Law. Students…

Discussion of problems students have with learning about Newtonian dynamics and kinematics focuses on the assumption that learning is promoted through confronting students with their own misconceptions. A computer-based modelling environment--DYNLAB--is explained, and a study conducted with high school boys in Scotland to test it is described. (29…

Describes study of Dutch high school students that compared instructional strategies in a computer programing course. Completion strategy, which emphasized the modification and extension of existing programs, was compared with generation strategy, which emphasized the design and coding of new programs. Future research is suggested based on results…

Compares the effectiveness of textual feedback to video feedback during two computer-assisted biology lessons administered to secondary students. Lessons consisted of a brief text introduction followed by multiple-choice questions with text or video feedback. Findings indicated that video feedback resulted in superior learning and comprehension,…
