Learning interaction

I dunno where to post this but I hope it´s ok to post it here. I need help with new ideas with learning interaction types. I want to come up with new types of interaction for learning and tests. I´ve done different types of: ‘true or false’, ‘multiple choice’, ‘fill in the blank’, ‘drag and drop’ and ‘hotspot’. I´m out of ideas. Does someone have any ideas or url:s for inspiration?
