This would be very helpful to us. Some background: We set up modules as units (i.e. "Waves", not "Week 1", etc.). So all items for a unit is contained within the module. This is usually 4 - 8 items, so it's not too much. I would prefer not to require students to complete a Module in order (I believe this would be a possible work around), as this would make some potentially unrelated assignments pre-requisites.
We have students complete labs online. The format is usually Pre-Lab Quiz, then directions, then Analysis Quiz, and finally a Discussion. I would like the Pre-Lab Quiz to be a pre-requisite to the directions.
