Authors' INTRODUCTION:THE success that the authors have had in using the following method in Boston and in Cambridge, both with children and adults in day and evening schools, has caused many teachers from different places to visit them in their class-rooms. The visitors have been pleased with what they saw, and many have tried the method, as they saw it, with their own classes. Their success and the difficulties they met with, caused many to repeat their visit to receive more help.In visiting a school-room a teacher gets many ideas from the writing on the boards, from the lesson given, and from the general atmosphere of the class, but at best it is the result of work she sees, and however well the teacher may explain her lesson, the purpose and aim of the teacher will certainly appear vague to a casual visitor. It is with the hope of helping those who have sought our aid, as well as others who have similar classes that we write this description and aim of our work in the school-room. It has above all things in its favor practical results results which in the beginning were obtained under the most adverse circumstances, and at present are obtained under only ordinary circumstances.The method has been the growth of fourteen years of work and cooperation. It is applicable to an evening school as well as to a day school. It can be used with a single pupil or with a class. It entails considerable labor, but it is the only method which can hold the interest, develop the idea, and successfully teach English to non-English-speaking people.It is with the kindest of intentions and the best of goodwill that the authors offer this production to the teachers who are working in similar classed in classes where there is only hard work for the teacher.
