The Experimental Reflection Portal, or "XRePort" is an online system that pairs students and teachers from different schools and allows them to "talk" about their common science investigations. In this way, students communicate their science knowledge "and" experience firsthand the benefits of the collaborative nature of science. The XRePort system was developed as part of a project to engage students in meaningful writing opportunities initiated by the "Science and Math to Go!" Program (a regional science materials support program) and the Center of Excellence for Instructional Technology Training, both based at Clemson University in South Carolina. It was created with funds from the U.S. Department of Education as a part of a Preparing Tomorrow's Teachers to Use Technology (PT3) grant, which was designed to assist university schools of education with the development of skill and comfort in the use of instructional technology. One of the goals of the XRePort project was to provide teachers and students the opportunity to collaborate online. This article highlights the experiences of fourth-grade students in South Carolina in designing and implementing the XRePort system in their school.
