Perfect Scores Indicate Good Students !? The Case of One Hundred Percenters in a Math Learning System

As a teacher or administrator, seeing a student scoring 100% in an exercise series within an online learning system would typically raise no immediate worries. This paper analyzes the "one hundred percenter" sessions in a math learning system. We argue that some student sessions with 100% score may actually not be predictive of student's learning success, and that a frequently exhibited student strategy of getting a perfect score by skipping exercises and repeating series is not ideal.
