During a large lecture class of 125+ students, we used a polling and live quiz tool called Socrative (www.socrative.com) to engage students in the lecture and test their knowledge on the topics covered.
During the portion of the lecture on reproducibility of research, we asked the following question:
Why might a study be irreproducible? Choose all that apply.
Socrative allowed us, and the class, to see the students' anonymous answers and discuss them.
See the [question slide][1] for more details.
