Hello Edward,
Confirmation, timely feedback, proactive announcements and the like, continue to provide higher student success than when they are not present. Most instructors know there is no one best solution, except maybe, an alert professional instructor who has a myriad of instructional approaches to address a variety of student types in the same class. Nevertheless, consistency with the 'old reliables' almost always has a positive impact, though not 100%. Thank you for your insights.
