The document summarizes two studies: 1. A comparative study that compared student satisfaction and learning outcomes between online and face-to-face courses. It found that while both groups were satisfied, face-to-face students had more positive views of interaction and support. 2. A non-comparative study that examined how a computer system called KnowCat helped develop students' metacognitive knowledge. Interviews found that KnowCat improved students' awareness of learning processes and strategies.
