How about using the PCA to analyze changes in learning styles?

Abstract

Nowadays collaborative educational processes require the use of increasingly sophisticated analytical tools to help teachers, tutors and students to identify, at best, emergent behaviors. In this paper we describe the use of a module that has been designed and developed to perform Principal Component Analysis as internal facility of the on-line learning place LIFE to identify groups of students characterized by similar learning styles and, as well, to study the evolution (one or two years away) of such styles. © 2012 Springer-Verlag.
