Network Science projects are endeavors in which a number of classrooms conduct the same scientific experiment and pool their data using World Wide Web technology. This paper reviews selected findings from research on these projects and describes the recent Web applications that were developed in response to these findings. Findings indicated that many of the observed classes were engaged in genuine inquiry, innovation, and cooperative learning. The telecommunications technology also fostered a genuine sense of community among the participating schools. Findings also indicated a general absence of any analysis of the data these classrooms were collecting. Factors that contribute to the failure of classes to analyze and understand the data they collect are discussed including cognitive, curricular, pedagogical, and technological challenge. Suggestions for adapting the technology to respond to these challenges are presented including the use of Collaborative Learning Environments On-Line (CLEO), a Web space that makes it possible for anyone with an Internet browser to create a data-rich project.
