The authors describe their design for an Internet-based learning environment called BeyondShare in which students are encouraged to gain a deep understanding of the learning material, reflect on the quality of individual constructions through sharing and peer evaluation, and synthesize cross-unit knowledge by integrating self- and peer-produced constructions. A sharing typology may consist of basic sharing, sharing with notification, sharing with feedback, or sharing with interaction. BeyondShare distinguishes itself by combining sharing activities with task structuring and cooperation/competition to achieve active learning. A formal evaluation of BeyondShare was performed with a class of 34 college students who created concept maps for a computer programming language and who were encouraged to become active learners by exchanging roles throughout the experiment. Evaluation results indicate that the students viewed BeyondShare as an easy-to-use environment that motivated them toward comprehensive knowledge integration by sharing construction products with their peers. Potential activities and suggested modifications are discussed. (Contains 4 figures and 6 tables.)
