Moodle MOOC: Creating Engaging Activities

The topic / task of the second week was „Knowing your students“ and „Creating Engaging Activities for them“.
I’ve made a tutorial for a combination of two Moodle activities: choice and forum. The choice activity would be for group selection, the forum activity for discussion on topics provided by the teacher. (I don’t like the technical group functionality of Moodle, because it often confuses teachers and I had cases when wiki content was gone after teachers had played around with the group settings.)
The combination suits many needs, is easy to create as a teacher and easy to use as a student. I’m very interested in basic solutions because I’m often in a situation where I have to convince teachers that using Moodle makes sense and that it works without problems.
