Abstract
The authors have developed and tested a system in which teachers and their students who have used an educational resource in the Digital Library for Earth System Education (DLESE) both submit on-line reviews of that resource using DLESE's Community Review System. They aggregate the students' reviews and generate an individualized report for the instructor on how his or her own students view the resource. The report for science teachers is formatted to show how well, on several dimensions, the resource worked. The report for science education professors is formatted to highlight how well students reflect on their own learning processes and identify what makes an educational resource effective.
