Certainly, that is a good solution in the current situation. In order to achieve that, you only have to freshly connect the series ID with the Player ID in your current TUWEL course (this works also for single videos of this series). There are 2 steps to follow:
Step 1: Open your last year's TUWEL course and go to the settings of the videos (external tool). Copy the IDs from the section "Allgemeines" / "Mehr anzeigen ..." / "Angepasste Parameter".
Step: 2: Now you have to re-connect your IDs within your current TUWEL course of this summer semester. On how to achieve this, please follow step 4 in this instruction.
