The pushback against 'scientific evidence' in education continues (I put 'scientific evidence' in quotes because in reality it is neither). This article calls for "an urgent halt to the imposition of ‘evidence-based’ education on Australian teachers, until there a fuller understanding of the benefits and costs of narrow, statistical evidence-based practice." It substantiates that call with some very reasonable points: "In education, though, students are very different from each other. Unlike those administering placebos and real drugs in a medical trial, teachers know if they are delivering an intervention. Students know they are getting one thing or another. The person assessing the situation knows an intervention has taken place. Constructing a reliable educational randomised controlled trial is highly problematic and open to bias."
