Supporting error correction feedback in tutorial dialogue with a mathematical domain reasoner
Speaker: Mark Buckley
Institution: Saarland University
Abstract:
Generating feedback in response to incorrect actions by students in tutorial dialogue depends on having a fine-grained analysis of the correctness of actions by a domain reasoner, on the one hand to detect that such feedback is necessary and on the other hand to provide the content to realise it. We have collected a corpus of tutorial dialogues between students and expert tutors in the mathematical domains of set theory and relations in which we have identified a number of types of feedback given to students in the case of partially correct, incorrect or irrelevant domain contributions.
In this talk we give a categorisation of the types of error correction feedback which can be given in response to such domain contributions. We then consider what the requirements are on the analysis of the contribution by a mathematical domain reasoner in order to be able to generate such responses.
