The authors of Make it Stick highlight the principle that reflection is itself a form of practice, that thinking about a problem is a form of useful rehearsal.
The recently revised standards for learning for CPAs put out by the National Association of State Boards of Accountancy (NASBA) stipulate for the first time that classroom learning must be active. For now, the rules for minimum interactivity are, indeed, minimal. To give formal credit, classes have to have one interaction per hour, of which that interaction can be nearly anything, including asking participants to reflect silently for a few seconds on a given question.
Lecturing for 45 minutes and then asking participants to reflect silently on a question asked by the lecturer is not necessarily effective design. But I applaud NASBA both for requiring interactivity and for keeping the requirement open. The more prescriptive the targets, the more proforma the execution. Keeping it open will result in many developers trying to do the minimum, for sure, but it may also help developers take ownership of active learning and try to understand NASBA’s intent.
