Not only is review thus essential in the beginning of the learning process with children, but it remains a vital factor as long as men and women undertake to learn. Review guarantees recall, and recall re-establishes "nerve connections" to the permanent fixing of impressions. Very little of our knowledge remains ours to a purpose unless it is gone over and over until it is thoroughly established. A truth that is taught in a Mutual lesson on a particular Tuesday night, but which is never referred to again, and therefore never recalled, very likely will soon be gone out of consciousness and usefulness. Those truths and facts which are of greatest functioning value to us are those which we continue to run over in our minds and ponder. The reinforcement of review is what establishes our permanent working stock of truth. Not only is review valuable as a matter of recall, but it makes for an enrichment of mental content which is altogether desirable. The real art of review lies in calling up an old truth in a new setting. Upon second perusal it is seen in skilful review from a slightly different angle so that each recall adds a reinforcement that makes for a clinching of thought which makes it permanent. It very often happens that the first time an idea is called to our attention it means but little, because our mental reaction is limited in the particular field of the presentation; the same idea in a new setting more in keeping with our experience may take on an entirely different significance. That teaching is best, therefore, which presents truth from the greatest number of angles possible, thereby guaranteeing the richest kind of associations in the minds of pupils. Another value that attaches to the review lies in the fact that it makes possible proper connection between new material and old. It is axiomatic in teaching that pupils learn new truths and take on new experiences, in terms of the old. Teaching that unfolds--that develops new ideas that are built upon those already understood--is the kind of teaching attended by best results. In our organizations, meeting as we do only once a week, we must appreciate the fact that in the intervening time, between meetings, hundreds of ideas have crowded into the mind and have displaced those that may have been there as a result of our teaching. By calling to mind those ideas of a week ago, we not only reinforce them, but we start a chain of thought to which it will be very much easier to add the link of today's work than to proceed as if forging an entirely new chain. No farmer goes out and plants grain on the unplowed field. He plows and harrows that the soil may be prepared not only to receive the seed, but to make generation possible. A review simply turns over the stubble field of the preceding week's work, making ready for the planting of new seeds that they may generate and develop.
