This paper presents a framework for understanding how the varyingexpertise, attitudes, and classroom activity structures of scienceteachers influence their students use of a suite ofcomputer-mediated communications tools in each of their classrooms.These issues are explored in the context of the Learning ThroughCollaborative Visualization (CoVis) Project. Findings indicate thatteacher designs for classroom activity relate strongly to thefrequency with which different tools are used. These results arepresented in order to build a case for understanding how innovationsare adopted in local contexts, as an important first step to bringingan innovation to scale.

This empirical study compared a graduate online course with anequivalent course taught in a traditional face-to-face format on avariety of outcome measures. Comparisons included student ratings ofinstructor and course quality; assessment of course interaction,structure, and support; and learning outcome measures such as coursegrades and student self-assessment of their ability to performvarious Instructional Systems Design (ISD) tasks. Results revealedthat the students in the face-to-face course held slightly morepositive perceptions about the instructor and overall course qualityalthough there was no difference between the two course formats inseveral measures of learning outcomes. The findings have directimplications for the creation, development, and delivery of onlineinstruction.

In this paper we report on the Probability Inquiry Environment(PIE), which facilitates the development of probabilistic reasoningby making available collaborative inquiry activities andstudent-controlled simulations. These activities guide middle schoolstudents toward a deeper understanding of probability, a domain thatis becoming increasingly important in the K-12 mathematics curriculaof the United States but which is notoriously difficult to learn. Astudy is described in which middle school students who participatedin the PIE curriculum significantly outperformed students whoparticipated in the schools traditional probability curriculum.We posit that this difference is due to the PIE curriculum fosteringstudent collaboration as the students employ their existingintuitions as building blocks for formal knowledge. This providesevidence that a productive learning environment should not be basedsolely upon the logical structure of the target domain, but shouldalso account for both students intuitive conceptions of adomain, as well as aspects of social interaction that shapestudents experiences. We then show the importance of intuitionsand social interaction by analyzing a case study in which studentsarticulated and revised their initial understandings of probabilityas they interacted with PIEcollaboratively making predictions,evaluating data, and interpreting representations.

With the increase of Internet and World Wide Web (WWW) usage inthe classroom, instructional activities are now being implementedthat use online conversation for knowledge-building. Current researchwith The WEB Project, a Technology Innovation Challenge Grantee,subtitled Creating a WEB of Evidence of Student Performance inNonverbal Inquiry and Expression can help inform practice inthis area. This paper presents a synthesis of current research onface-to-face and online conversation and a short analysis of episodesof online conversations captured from The WEB Exchange(www.webproject.org), together with a few perceptions from a studentfocus group. Lessons learned and implications for practice are thenpresented.
