摘要

In modern classrooms, scientific probes are often used in science labs to engage students in inquiry-based learning. Many of these probes will never leave the classroom, closing the door on real world experimentation that may engage students. Also, these tools do not encourage students to share data across classrooms or schools. To address these limitations, we have developed a web-based system for collecting, storing, and visualizing sensor data, as well as a hardware package to interface existing classroom probes.;This system, The Internet System for Networked Sensor Experimentation (iSENSE), was created to address these limitations. Development of the system began in 2007 and has proceeded through four phases: proof-of-concept prototype, technology demonstration, initial classroom deployment, and classroom testing. User testing and feedback during these phases guided development of the system.;This thesis includes lessons learned during development and evaluation of the system in the hands of teachers and students. We developed three evaluations of this practical use. The first evaluation involved working closely with teachers to encourage them to integrate activities using the iSENSE system into their existing curriculum. We were looking for strengths of the approach and ease of integration. Second, we developed three "Activity Labs," which teachers used as embedded assessments. In these activities, students were asked to answer questions based on experiments or visualizations already entered into the iSENSE website. Lastly, teachers were interviewed after using the system to determine what they found valuable.;This thesis makes contributions in two areas. It shows how an iterative design process was used to develop a system used in a science classroom, and it presents an analysis of the educational impact of the system on teachers and students.
