AIDS TO VISUALIZATION.
A feature of the coming meeting of the American Historical Association in New York will be an exhibit, at Teachers’ College, of special aids to visualization in the teaching of history. The exhibit will consist of casts, models, pictures, historical albums, visualization charts, maps, plans, and other similar material, and of such apparatus as the stereoscope, the ordinary lantern, the “reflectroscope,” the “microscope,” and the motion picture lantern. The interesting and inexpensive models found in Germany and the French and German charts and albums will have a prominent place. A few types of recent foreign text-books will also be included. In the main, only such aids as are now actually available for school use will be shown. The names of dealers and the cost of material will in each case be indicated. The aim of the exhibit is to answer as specifically as possible the questions usually asked by teachers who feel the need of greater emphasis upon this aspect of historical instruction.
