Evidence of Evidence-Based Teaching
Evidence-based teaching seems like the new buzzword in higher education. The phrase appears to mean that we’ve identified and should be using those instructional practices shown empirically to enhance learning. Sounds pretty straightforward, but there are lots of questions that haven’t yet been addressed, such as: How much evidence does there need to be to justify a particular strategy, action, or approach? Is one study enough? What about when the evidence is mixed—in some studies the results of a practice are positive and in others they aren’t? In research conducted in classrooms, instructional strategies aren’t used in isolation; they are done in combination with other things. Does that grouping influence how individual strategies function?
