You have conducted a research study to assess the impact of online learning on college students. Which test will take help for drawing conclusions about the usefulness of online learning?
You raised an important issue. I think there are many tests available to examine the usefulness of e-learning - the test depends on the case - and the context:

You could do pre- and post-knowledge tests of the subject matter.
You could also do qualitative research by asking about student responses to the online learning; i.e., did it hold their interest, do they feel that they learned as much as they wanted/needed to learn, what was easy, what was hard, what suggestions do they have for improving the experience?
