In order to make reviews easily and rapidly, the teacher should hold in mind large masses of the lessons learned, ready for instant use. He is thus able to begin at any spare minute an impromptu miscellaneous review on any part of the field. New questions started on old lessons, new illustrations for old texts, new proofs for old statements, will often send the pupil back with fresh interest to look again into the old lesson. The final review, never to be omitted, should be searching, comprehensive, and masterful, grouping all parts of the subject learned as on a map, and giving the pupil the feeling of a familiar mastery of it all. Seek as many applications as possible of the subject studied.
Every thoughtful application involves a useful and effective review.
Forget not the value of pencil and pen work in reviews. This work can be done out of class, and it shows for itself. Ask questions on previous lessons. If this is a frequent exercise, the pupils will make volunteer studies both to get questions and to be ready with answers. The first violation of the law is the total neglect of reviews.
