Les effets de la distance sur le contenu d'un cours : une analyse avec LSA

Abstract : In this article we analyze the data of an earlier experiment in which two modes of a teachers’ discourse were compared: at a distance versus face-to-face. The results showed no significant differences between the two forms of discourse concerning its lexical, morphosyntactical, and pragmatical forms. We present here a new analysis in which the Latent Semantic Analysis method is used to reanalyze the data in a semantic perspective. Although there was again no significant difference between the two modes, we show the interesting capability of LSA to match semantically two separate pieces of text. We then discuss how LSA could be used first, as the heart of a distance learning system and second, to operationalize the structure variable of transactional distance theory.
