Subclaims¶

q2 i? The study concludes that two domain characteristics — information richness of the solution and complexity of the solution process goal structure — distinguish the appropriateness of the two paradigms. → Viswanathan Kodaganallur 2005

q2 · i? · design · r?

The study's principal conclusion from building both tutors for one domain: "two characteristics of the problem domain are key in distinguishing the appropriateness of the approaches for a given problem domain".

"Principally we conclude that two characteristics of the problem domain are key in distinguishing the appropriateness of the approaches for a given problem domain."

Discussion¶

Related Claims¶

• The constraint-based tutoring paradigm is feasible only for domains in which the solution itself is rich in information, whereas model tracing has no such restriction — a narrower finding that bears on this claim
• Building a model-tracing tutor requires greater development effort than building a constraint-based tutor for the same domain — a narrower finding that bears on this claim
• Model tracing is superior for targeted, high-quality remediation, and this superiority increases with the complexity of the solution process goal structure — a narrower finding that bears on this claim
