This paper describes the results of a two-semester-long study of the effects of student-centered instruction on Precalculus courses. We also describe our teaching approaches centering around students, which include a mixture of lectures, student presentations, group work, discussion, and guided investigations. Students were taught with either the…

We report the student response to a two-year transformation of a one-semester organic chemistry course for nonchemistry majors. The transformed course adopted a peer led team learning approach and incorporated case studies. Student attitudes toward the course transformation were assessed throughout the semester, and adjustments to the methods were…

This study investigates differences between collaboration methods in two summer enrichment classes for students entering the sixth grade. In one treatment, students used pair programming. In the other treatment, students engaged in frequent collaboration, but worked on their own computer. Students in the two treatments did not differ significantly…

Describes a study that examined the effects of cooperative versus individual computer-based instruction on the performance of high- and average-ability fourth-grade students. Effects of learner and program control are investigated; student attitudes toward instructional content, learning in groups, and partners are discussed; and further research…

This study investigated the effects of instructionist (navigational, functional) versus constructionist (adaptive) World Wide Web (WWW) site environments on collaboration, achievement, attitudes, and perceived level of learner controls reported by students after working in cooperative dyads within the different types of Web-based learning…

Compared performance of low-aptitude remedial adults learning to solve mathematics word problems. Participants worked either alone or as collaborative dyads and received instruction/practice using either the Word Problem-Solving Environment (WPSE), an exploratory system over which learners exercise control, or Solver, a structured and directive…

This paper reports on a study investigating the effects of studying alone or in cooperative-learning groups on the performance of high and low achievers. The effects of completing computer-based instruction using either learner or program control are also examined. A total of 92 sixth-grade students were classified by Stanford Achievement Scores…

This study examined the effects of instructional control and aptitude composition on performance, interaction, and attitudes during a computer-based cooperative science lesson. A sample of 152 fifth and sixth grade students completed the instruction either under the learner control (LC) or the program control (PC) treatment. In the LC treatment,…

Describes a study which investigated the impact of implementation strategies on learner behavior and engagement in a university classroom-based World Wide Web learning activity. In particular it examined the influence of a collaborative activity on learner behavior and the role played by a printed guide designed to focus and direct learners'…

This study examines the effects and interactions of World Wide Web page design on student navigation and decision making in Web-based learning environments. The following research questions are examined via quantitative, qualitative, and exploratory data analysis procedures: (1) Does instructional grouping or Web page format effect navigational…

Reports on a study investigating perceptions of K-12 teachers, educational technology faculty, and educational technology graduate students about instructional design, cooperative learning, learner control, school reform, computers and media, and implementation of a key practice in each area of their teaching.
