The current research aims to add to the body of knowledge about different types of feedback. This paper reports the investigation of different types of automated model-based feedback. The study examined three forms of model-based feedback using different methods-concept mapping and written text-for presenting the solution of a task to be solved. Seventy-four students from a German university participated in this experimental study and were randomly assigned to one of the three experimental groups: (a) cutaway feedback, (b) discrepancy feedback, and (c) expert feedback.
