using point assignments
Hi-I may use the option - assignments-gaining points (xp) but can the students still remain only at the basics? The reason is that they want to get out of learning more so they end up repeating the basics over and over again. Thank you,
If you only do XP assignments, yes. They can just keep repeating Basics 1 Lesson 1 and farm for XP. I would combine XP assignment WITH skill assignments and randomly check students' trees to make sure they are completely (or almost completely) gold. Don't announce those checks, because then they can just quickly buzz through and regold everything when they have to. If they don't know when it's coming, they'll keep everything gold more frequently or suffer the consequences.
