A couple of participants in this forum have mentioned Don Norman's significant contributions to the development of mental model theory (cf. Norman, 1983). A typical taxonomy of internal learning states as defined by contemporary cognitive psychologists includes constructs such as "simple propositions, schema, rules, general rules, skills, general skills, automatic skills, and mental models" (Kyllonen & Shute, 1989). The authors of these taxonomies imply that mental models are the richest constructs of learning states that have been conceptualized to date.
It also appears that many (most?) participants in ITForum would agree that a wide variety of learning strategies, including memorization, direct instruction, deduction, drill and practice, and induction, may be required in education and training depending upon the type of knowledge state to be constructed (Schank & Jona, 1991).
My first question to Don is: What is your current thinking about mental models and learning? (In 25 words or less.) I realize that you may simply prefer to refer us to more current references.)
My second question is: Does learner-centered education provides a better basis for the construction of sound mental models than other forms of education? I think you'll say "yup," so please tell us why!
