The responsibilities of the teachers for the auditorium period have been discussed. Under the old Gary plan each auditorium period was in charge of one teacher who acted as assistant principal. The teachers alternated in organizing the dramatic and other features of the auditorium work. Recently Superintendent Wirt has decided that this auditorium work functions better if it is specialized. In the new 72-school program, four teachers give their time exclusively to the auditorium exercises. One teacher has charge of the music; one has charge of the art, literature, history, civics, and current events; one has charge of the presentation of material relating to the science work; and one has charge of the presentation of the material relating to the shops and industries. In a properly equipped auditorium, with stereopticon lantern, motion-picture machine, stage, player-piano, organ, and phonograph, the auditorium teachers can do many things better with large numbers of children than the regular teachers can do with small numbers. The regular classroom teachers are expected to coöperate in this frequent presentation of work by their classes in the auditorium in order to use it as a place for “application” work and for motivating the academic work of the school. In the new program, the “application” work is also specialized. Experience has shown that some teachers have a special talent for this imaginative and constructive side of teaching, and prefer to devote their entire time to it. In this scheme, the “application” teachers have six classes daily out of a total of twelve classes in each of their respective groups. They are thus able to meet each of the twelve classes of their respective groups every other day, week, month, or term. Or these teachers may select from each of the groups of three classes the pupils who need special work in language and mathematics, and meet these pupils every day. For the average pupil all of the opportunity necessary to make an application of his language and mathematics is provided in the regular manual-training, drawing, music, and expression classes. The “application” teachers meet their respective classes in the manual-training, drawing, music, and expression rooms. The facilities of these special rooms are used for “application” purposes. The “application” teachers are expected to make suggestions to the special teachers of these subjects concerning the opportunities to teach language and mathematics through the “application” opportunities of the regular work of their respective subjects. Each “application” teacher may be constituted the head of a group of eight teachers. The “application” teacher is the correlating agent for all the work of the twelve classes; also she works with all of the twelve classes as a constructive examiner, and is constantly placing before the children real problems of the type that the world of industry, business, and citizenship will place before them when they leave school.
