This research examines two different kinds of feedback-mechanism to scaffold problem solving as well as interaction in an asynchronous PBL course. An automated feedback mechanism has been used to enhance interaction and group well-being during computer supported collaborative learning. We tracked individual contribution behavior as well as learners’ motivation during collaborative problem-solving by means of an asynchronous communication platform. These data have been used to automatically generate visual aids, providing feedback about group members’ participation as well as motivational clues. A second feedback mechanism has been applied by aggregating learners’ problem solving discourse into a meta-document. This document revealed groups’ problem-solving strategies as well as their progress during different problem solving stages. We examined how this scaffolding methodology based on a group’s own behavior enhanced problem-solving outcomes. Results suggest positive influences of feedback mechanisms on problem-solving as well as motivational parameters.
