An Internet Assessment Service System for Cognition Diagnosis Based on Integration of Ordering Theory and S-P Chart

The purpose of this study is to provide an integrated methodology for learning assessment and cognition diagnosis. This integrated method is based on ordering theory (OT) and student problem chart (S-P chart). The authors implement the real-time Internet assessment service system based on this integrated method. This Internet system could classify students into proper groups according to student problem chart algorithm. Besides, ordering theory is adopted to analyze item hierarchies which imply characteristics of cognition for students. The users of this Internet service system are mainly teachers and they could upload their testing data anytime. Teachers could design proper teaching materials and pedagogy for remedial instruction based on the information of cognition diagnosis from this system.
