"Who has been to Dairy Queen® and purchased a Blizzard?®" Ms. Bosetti asked her students. During the summer, Bosetti had seen many of her former and future students at the local Dairy Queen enjoying Blizzard desserts and wondered, "Which Blizzard size is the best value?" She used this context for a ratios and proportions task…

The venerable aphorism "an old dog cannot learn new tricks" implies that the elderly rarely learn anything new--in particular, scientific knowledge. On the basis of "learning by doing," the present study emphasized knowledge application (KA) as elderly subjects collaborated on the design of a toy flying saucer (UFO). Three…

This article presents a designed learning environment intended to engage students in learning about the relationships among multiple representations as they work together on a shared task. Over the course of several extended problem-solving sessions, groups developed several successive alignments of participants and representations as they learned…

This study of third graders examined whether qualitatively distinct cooperative computer environments (using LOGO and curriculum-based instruction in writing) engender social experiences that enhance motivation and self-concepts as learners; and the extent to which differences in motivation and self-perception accounted for differences in…

Describes a study of fifth- and sixth-grade students that investigated the patterns of peer interaction among students working cooperatively in small groups on a computer-based problem-solving task and the effects of gender and group composition on peer interaction. Suggestions for future research are included. (Contains 86 references.) (LRW)

Eighty ninth graders who solved an algebra problem in groups of four showed status effects at the individual level. The students had filled out preactivity questionnaires about mathematical status and social status and a postactivity leadership questionnaire. Hierarchical regressions and path analyses show that, at the group level, solution score…

Presents an activity through which students develop mathematical concepts connected to area and perimeter in a rich, real-life setting and use tables, graphs, diagrams, and spreadsheets to explore the problem, see relationships, and make and test conjectures about those relationships. Encourages algebraic thinking. (SYB)

The Superhighways Teams Across Rural Schools (STARS) program sought to demonstrate how pupil learning and teacher professional development might be enhanced by the use of multimedia resources made available over communications networks. Subsidiary goals included developing strategies to support isolated gifted students through collaborative work,…

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…
