The one ruled by personality and broad, humane principles; the other was an apostle of force, fitfully administered, as, in fact, it must of necessity be administered. The one was conscious of his authority; the other forgot it and worked man to man with his pupils. The one exhausted his force and failed; the other scarcely ever drew upon his reserve and never lost a pupil friend. The one ground his teeth in rage at the perversity and rebellion of his pupils, the other enjoyed their friendship and reveled in the memories of sympathetic appreciation of his labors. In short, one was beloved by all, the other despised. Of all the words from tongue or pen that explain the more desirable of the two methods described, none is better than the word Coöperation. This is the capstone of our five fundamental principles—Suggestion, Substitution, Expectation, Approval, Coöperation. Approval of good effort, in fact, turns out to be one mode of coöperation with the pupil. It ministers to his self-love and elicits further effort. A teacher can not exemplify this one principle of coöperation without hitting upon or consciously employing all the others we have named and illustrated. “I work with my pupils,” is the highest self-praise a teacher can utter. It is a simple, modest, unassuming statement; if true in its deepest sense, he who thus speaks of himself is a perfect teacher and disciplinarian. We commend this gospel to coöperative school-room discipline to every aspiring teacher who reads these volumes; we can only hope that every one may be converted heart and soul to this mode of action and with religious devotion set about remoulding his treatment and management of school children so that he truly may be a Friend to Man.
