چکیده

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. RÉSUMÉ. Dans cet article, nous présentons une application utilisant la plateforme SUMMA de développement et de test de l’Analyse de la Sémantique Latente développée par Baier, Lenhard, Hoffmann & Schneider (ce numéro). SUMMA-LSA a été utilisé pour évaluer les connaissances d’élèves de 5◦ et de 4◦ dans le domaine de la biologie, !le fonctionnement du corps humain et ses besoins en énergie", à l’aide de QCM classiques et!évidentiels" et de questions Studia Informatica Universalis. ouvertes. Les corrélations hautement significatives entre les performances des élèves et les valeurs de cosinus fournies par LSA ouvrent des perspectives prometteuses dans le développement de systèmes d’apprentissage en ligne, adaptés au niveau de connaissances des apprenants, et permettant des (auto)-évaluations en temps réel.
