Reflection: Accountability DNA Extraction Lab (Day #1 of 2) - Section 4: Closure: What did we learn? Where do we go from here?


According to Doug Lemov's Teach Like a Champion, "One consistent finding of academic research is that high expecations among teachers are the most reliable driver of high achievement among students, even students who do not have a history of strong achievement." (p. 89) There are a number of different ways to establish the culture of high expectations. One that I use here is to clearly provide the tasks to be achieved, scaffolded instruction, and accountability. With the companion website, the lab template, and the expectation that each member is responsible for specific team-oriented tasks there is no reasonable excuse not to be prepared! If not, then that team must spend the extra time to get ready according to my standards without holding back other teams that have already passed muster.

  Make a plan and then stick to it!
