Abstract: This paper introduces the Repertory Grid Technique (RGT), developed in personal construct psychology, for Technology Enhanced Formative Assessment (TEFA). RepertoryGrid is a method for eliciting personal constructs of learners about elements belonging to thetopic of study. The method of Repertory Grid is presented first followed by brief descriptions of two classroom studies and two eye-tracking controlled laboratory studies. Empirical findings contribute to a better understanding of the integration of Repertory Grid into teaching as an in-class learning activity or a take-home exercise, methodological support for teachers to designing and deploying RGT exercises, and computational support for visualizing theRepertory Grid data at the individual student level and whole classroom level for teaching analytics” purposes. We outline the design and development of the Repertory Grids for Formative Assessment (RGFA) tool and conclude with directions for future work.
