I have built several apps in Norwegian about hunting, philosophy etc. Students use the app to learn a subject and test their knowledge before doing their exam. In current state i have one question with three alternatives, where one is correct. The student will be presented with the solution to the question after they have chosen the alternative, and not on the end of the test.
For example:
What is the the capital city of Australia?
- Canberra
- Sydney
- Melbourne
I was wondering if anyone know if there is any research on if students learn more/less/equal by being presented with 4 alternatives instead of three.
For example:
What is the the capital city of Australia?
- Canberra
- Sydney
- Melbourne
- Edmunton
Does this have any effect for learning, since it's less probable to just check the correct by chance. Maybe students have to do more active thinking since it's more alternatives to think about, and therefore learn more?
