Analyses des classes et des transitions latentes : des outils pour documenter le parcours de développement des compétences.

Abstract

Our proposal is that the process of validating the construct of a competency inferred from an observation grid raises a multivariate and multi-dimensional latent classification problem. The analysis models a given competency based on the identification of discrete classes using latent classification (LCA) and latent transition (LTA) models. Then, the approach is illustrated in the context of the growth of the morphosyntax competency of learners of French as a second language. Advantages and limits of the analysis are outlined.
