Software technology for learning and teaching

Bastiaan Heeren and Johan Jeuring

In this day of lectures we will discuss how software technology can contribute to learning and teaching. In particular, we will discuss how we can support learning using digital technologies: learning environments, intelligent tutoring systems, serious games, etc. Such environments diagnose or assess student actions or student products, and give hints or worked-out solutions to a student. In all of these environments, we need to encode what constitutes desirable behavior of a student. Based on a description of a desirable way to solve an exercise, we need to find out if a student is making progress, or strays away from the goal. We use rewrite strategies and parsing techniques to diagnose the steps from a student. Student actions are interpreted as rewrite steps, and we parse these steps against rewriting strategies, possibly including buggy steps or strategies.
