Another option is to do a Scavenger Hunt and let your students work in groups to discover key points together. You are still simply asking questions for them to answer, but framing it as a Scavenger Hunt and allowing them to work together adds some fun to heighten your students’ engagement. I used this to help students find resources in the classroom and to understand the structure of our textbook. It's also ideal for guiding them through key internet resources.
A friend of mine is taking her first online course. She was worried, because as she logged on, she didn't know where to find anything. Her first assignment was a scavenger hunt, which guided her to the different resources and aspects of the site. The teacher required each student to score 100 on a quick quiz about locations of items before they could move further in the class.
Interesting--they could take the test as often as they liked, and they could refer to the site. So, she ensured success. She also handled basic directions without taking time from her instruction.
How could you use scavenger hunts to streamline or enhance your instruction?
