In the analogue days we had the concept of one's own summary of what he has learned. Ideally done as the course progressed, naturally on paper. Often students were allowed to take their own summary to the exam - in extreme cases, it was the only document allowed during the exam.
Are you looking for the digital equivalent? AL's suggestion is the one-to-one translation. Here the summary becomes an activity of its own. The method Joost proposed is the modern "instructional design" approach. It eliminates the "journal" alltogether, but forces the students to do those tasks through https://docs.moodle.org/en/Activity_completion.
