Roberto Gregorius

Dr. Gregorius' research interest is in the optimization of learning outcomes and student performance in various learning environments and applied teaching methods. Dr. Gregorius is particularly interested in the intersection of learning theory: what learning means and how it is measured, with teaching methods: practical procedures for inculcating knowledge. Currently, he is looking into the development of Flash-based animations with an artificial intelligence tutor to support student-centered, self-guided learning, with the expectation that using such materials in advanced teaching methods will improve student learning.
