From Education Week:
Accompanied by local educators, I visit dozens of schools every year all around the United States. I assure you that the lessons we witness in the great majority of classrooms violate most of the elements of well-structured lessons. We seldom see clear, posted learning objectives; instead, multiple segments of instruction are often breezily conveyed as students sit mystified or are visibly inattentive or tuned out. And it is the rare lesson where we see instruction that seeks to ensure success for every student on each phase of the lesson, with multiple attempts to clarify or re-teach.
This is a scandal on the order of refusing to administer life-saving antibiotics to needy patients. And it is wholly unnecessary, because the solution is so simple: All we need to do is devote serious time and attention to ensuring that every pre-service student, current teacher, and administrator learn, revisit, and practice (and practice and practice) these hugely effective components until they are mastered and consistently implemented in all of our classrooms. We should make them the focus of faculty, team, and department meetings, as well as professional development sessions. If we do this, we won’t have to wait long to see their impact, which will surpass the effects of all other initiatives thus far launched in this confused, distracted era of “reform.”
