"We came up with a method for testing whether the students are actually learning or just being influenced by other students who they think know the right answer," said Michelle Smith, a science teaching fellow with CU's Science Education Initiative and a research associate in MCD biology.
The researchers used pairs of similar clicker questions in lectures during the semester and evaluated student responses. The students answered the first question of the pair individually, and then talked to their neighbors about their answers.
When they were asked to answer a second, similar question individually, about 50 percent of them got the question right on the first try. The researchers said that after talking to neighbors, the number jumped to 68 percent.
According to them, the number jumped again to over 70 percent, much better than the 50 percent of individual correct answers on the first question, when the students individually answered a follow-up question about the same concept.
"There was no influence from the instructor during the clicker question series. We were just giving students the opportunity to talk to each other," said Smith.
"The important point is that none of the students were told what the right answer was. Even when students in a discussion group all got the initial answer wrong, after talking to each other they were able to figure out the correct response, to learn. That was unexpected, and I think that's dramatic," said Su.
