At Quincy, Massachusetts, there is a training class of thirty students. The pupil teachers act as assistants in the schools, receiving no compensation, except the guidance of experienced teachers, and theoretical instruction from the superintendent. They usually teach in several grades during the year, but those who show special aptitude or wish to teach in any particular grade are allowed an alternative of remaining in that grade. At the Coddington school, one of the training schools for the Quincy Training Classes, I heard very good lessons given in reading, phonics, number, English and geography. A reading lesson, given to ten or twelve children about seven years old, was to teach one new word, “Flag.” The class stood around the teacher at one part of the wall slate. After carefully revising many of the words learnt in previous lessons, the teacher drew a flag on the board. Then she wrote the word as a whole, underneath the drawing. Then she told a short story about a flag, wrote the word in different coloured chalks, wrote sentences involving only known words and the new word “flag.” When the children could read these sentences easily, they were made to pick out the word “flag.” Some were allowed to erase the word, some to write it again. Every possible device was used in the lesson to associate the complete written expression with the spoken word and the idea. At the end of twenty minutes, when the association was complete, the new word “flag” was written among the list of known words, kept constantly on the board, and the children were sent to their seats. I noticed in all the reading lessons in which words and sentences were taught as wholes, that clever teachers constantly used the device of erasing the word or sentence to be taught. This, when skilfully done, secures concentration of attention on each word, by allowing the children only a limited time to note its general shape, before being required to represent it on the board or slate. The constant erasure and repeated re-writing of a word ensure repeated short acts of intense attention on the part of the children, and so help greatly in the learning of the new word. A lesson in “number” or arithmetic, given to the same class, was devoted to problems in addition, subtraction, multiplication and division of numbers below ten. Many devices were used for interesting the class. The children were sent to work at different parts of the wall slate, and were encouraged to contribute problems for the class. The general use of the wall slate is seen to be of great advantage, especially in such lessons as these. By means of it, supervision of individual work is very easy, and corrections can be made valuable to the whole class.
