Automated Analysis of Students' Free-text Answers for Computer-Assisted Assessment

, , and . Proceedings of the TAL & ALAO Workshop at the 13th Conference Sur, (2006)

Abstract

We present an approach to Computer-Assisted Assessment of free-text material based on symbolic analysis ofstudent input. The theory that underlies this approach arises from previous work on DidaLect, a tutorial system for reading comprehension in French as a Second Language. The theory enables processing of a free-text segment for assessment to operate without precoded reference material. A study based on a small collection of student answers to several types of questions has justified our approach, and helped to define a methodology and design a prototype.
