Knowledge evaluation based on LSA: MCQs and free answer questions
Résumé
In this paper, we present an application using the SUMMA-LSA platform developed by Baier, Lehnard, Hoffmann & Schneider (this volume). SUMMA-LSA was used to evaluate biology knowledge of 7th and 8th grades students dealing with The human body energy requirements . Student knowledge has been measured by means of classical and “evidential” multiple choices questions (MCQs) as well as open questions. The highly significant correlations between student answers and LSA cosine values opened encouraging perspectives in the development of e-learning systems that allows self-evaluations in real time and adaptation to learners’ knowledge.
