Mischief and disorder.--An especially difficult kind of distraction to control is the tendency to restlessness, mischief, and misbehavior which prevails in certain classes or on the part of an occasional pupil. Pupils sometimes feel that the teacher in the church school does not possess the same authority as that exercised by the public-school teacher, and so take advantage of this fact. The first safeguard against disorder in the class is, of course, to secure the interest and loyalty of the members. The ideal is for the children to be attentive, respectful, and well behaved, not because they are required to, but because their sense of duty and pride and their interest in the work leads them to this kind of conduct. It is not possible, however, continuously to reach this ideal with all children. There will be occasional cases of tendency to disorder, and the spirit of mischief will sometimes take possession of a class whose conduct is otherwise good. Whenever it becomes necessary, the teacher should not hesitate to take a positive stand for order and quiet in the class. All inattention is contagious. A small center of disturbance can easily spread until it results in a whole storm of disorder. Mischief grows through the power of suggestion, and a small beginning may soon involve a whole class. There is no place for a spirit of irreverence and boisterousness in the church school, and the teacher must have for one of his first principles the maintenance of good conduct in his classroom. No one can tell any teacher just how this is to be achieved in individual cases, but it must be done. And the teacher who cannot win control over his class would better surrender it to another who has more of the quality of leadership or mastery in his make-up, for no worthy, lasting religious impressions can be given to noisy, boisterous, and inattentive children. Distractions by the teacher.--Strange as it may seem, the teacher may himself be a distraction in the classroom. Any striking mannerism, any peculiarity of manner or carriage, extreme types of dress, or any personal quality that attracts attention to itself is a distraction to the class. One teacher may have a very loud or ill-modulated voice; another may speak too low to be heard without too much effort; another may fail to articulate clearly. Whatever attracts attention to the speech itself draws attention away from the thought back of the speech and hinders the listener from giving his full powers to the lesson. A distracting habit on the part of some teachers is to walk back and forth before the class, or to assume awkward postures in standing or sitting before the class, or nervously to finger a book or some object held in the hands. All these may seem like small things, but success or failure often depends upon a conjunction of many small things, each of which in itself may seem unimportant. It is often "the little foxes that spoil the vines."
