Expert Tutors Feedback Is Immediate, Direct, and Discriminating
نویسندگان
چکیده
1 Feedback is critical in both human and computer tutoring because it has directive, facilitative, and motivational functions. An understanding of the feedback strategies of expert human tutors is essential for ITSs that aspire to model such tutors. Although previous research suggests that expert tutors provide indirect and delayed feedback, methodological concerns limit the generalizability of these findings. In order to alleviate some of these methodological concerns, we conducted a fine-grained analysis of the feedback strategies of 10 expert tutors across 50 sessions. We analyzed the likelihood that tutors provide positive, negative, and neutral feedback immediately following students’ correct, partially-correct, error-ridden, vague, or no answers. Our results support the conclusion that expert tutors feedback is direct, immediate, discriminating, and largely domain independent. We discuss the implication of our results for the development of an ITS that aspires to model expert tutors.

Techniques used by "expert" and "non-expert" tutors to facilitate problem-based learning tutorials in an undergraduate medical curriculum.
BACKGROUND There is inconclusive debate within the literature as to whether the best problem-based learning (PBL) tutors are subject experts or not. The debate hinges on whether knowledgeable tutors are tempted to intervene too often in PBL discussions compared to non-expert tutors, and whether the latter may not be able to sufficiently challenge the students' level of understanding. PURPOSE ...
متن کاملCognitive Tutors: Lessons Learned
This article reviews the 10-year history of tutor development based on the advanced computer tutoring (ACT) theory (J. R. Anderson, 1983, 1993). We developed production system models in ACT of how students solved problems in LISP, geometry, and algebra. Computer tutors were developed around these cognitive models. Construction of these tutors was guided by a set of eight principles loosely base...

Model–tracing tutors have consistently been among the most effective class of intelligent learning environments. Across a number of empirical studies, these tutors have shown students can learn the tutored domain better or in a shorter amount of time than traditionally taught students (Anderson et al., 1990). Unfortunately, the creation of these tutors, particularly the production system compon...

متن کاملToward a Computational Model of Expert Tutoring: A First Report
We are exploring the differences between expert and less expert tutors with two goals: cognitive (what does tutoring tell us about learning) and applied (which features of tutoring dialogues should be included in interfaces to ITSs). We report results from human tutoring dialogues where an expert tutor was compared to less expert tutors. We also report results from a comparison among four versi...
