Vary the pace. Vary the setting - use indoor and outdoor locations for reviewing. Use meandering, open-ended methods. And use business-like tightly structured ones. Involve learners in setting the agenda, but don't abandon your own.
Stimulation is as important during reviews as it is during the activities being reviewed.
The more learners know about their own ''recipes for success'', the greater the chance that they will use them again. Also the very process of studying the ''secrets of this success'' makes future success more likely - whether or not clear recipes are produced. This store is full of items that will help them to be successful. Ask them to take a look in their store and tell you what they see. This is similar to the 'My Ten Best Points' exercise.
