Diagnostic Cognitive Assessment and E-Learning.
Leung, Kit H.
Diagnostic Cognitive Assessment (DCA) is an alternative dynamic assessment. It aims at measuring cognitive processes for effective learning support and coaching. DCA is embedded in a digital coaching system (DCS) as an executive director. It contains three sub-models: Expert Knowledge Model, Inference Model, and Student Model. While the Expert Knowledge Model emulates human tutoring by modeling the expert tutor's knowledge, probabilistic inferences of knowledge acquisitions are derived from the Inference Models that are driven by Psychometrics and Bayesian Networks. By observing the students' performances, the Inference Models examine and interpret how learners learn as they trace, track, and record learning activities. The Student Model delivers customized diagnostic analysis to learners, guidance to DCS's Scaffolding function to map the learner's knowledge structure and schema, immediate dynamic diagnosis to Real Time Evaluation of DCS, and aids to collaborative learning in the E-Learning Community.
