The DIAGNOSER project: Combining assessment and learning

DIAGNOSER is an Internet-based tool for classroom instruction. It delivers continuous formative assessment and feedback to high school physics students and their teachers about the correct and incorrect concepts and ideas the students may hold regarding physical situations. That is, it diagnoses misconceptions that underlie wrong answers of students, such as a confusion of velocity with acceleration. We use data about patterns of student responses, particularly consistency of errors from question to question, to improve the system’s understanding of student concepts.
