Beyond intelligent tutoring systems: Using computers as METAcognitive tools to enhance learning?

摘要

Framed by the existing theoretical andempirical research on cognitive and intelligenttutoring systems (ITSs), this commentaryexplores two areas not directly or extensivelyaddressed by Akhras and Self (this issue). Thefirst area focuses on the lack of conceptualclarity of the proposed constructivist stanceand its related constructs (e.g., affordances,situations). Specifically, it is argued that aclear conceptualization of the novelconstructivist stance needs to be delineated bythe authors before an evaluation of theirambitious proposal to model situationscomputationally in intelligent learningenvironments (ILEs) can be achieved. The secondarea of exploration deals with the similaritiesbetween the proposed stance and existingapproaches documented in the cognitive,educational computing, and AI in educationliterature. I believe that the authors are at acrossroads, and that their article presents aninitial conceptualization of an important issuerelated to a constructivist-based approach tothe computational modeling of situations inILEs. However, conceptual clarity isdefinitively required in order for theirapproach to be adequately evaluated and used toinform the design of ILEs. As such, I invitethe authors to re-conceptualize their frameworkby addressing how their constructivist stancecan be used to address a particular researchagenda on the use of computers as metacognitivetools to enhance learning.
