Evidence-based teaching seems like the new buzzword in higher education. The phrase appears to mean that weāve identified and should be using those instructional practices shown empirically to enhance learning. Sounds pretty straightforward, but there are lots of questions that havenāt 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 mixedāin some studies the results of a practice are positive and in others they arenāt? In research conducted in classrooms, instructional strategies arenāt used in isolation; they are done in combination with other things. Does that grouping influence how individual strategies function?
