This bulletin represents a cooperative effort of nine secondary school specialists in the Office of Education to picture the provisions used in large high schools to adapt teaching methods in different subjects for pupils who are not average. It is recognized that a pupil may be a rapid learner in one subject and a slow learner in another. Each of the specialists gather and reported the information relating to his special field. A common pattern was followed in presenting the data in tabular form. As will be obvious to the reader, each writer was encouraged to use his own individual style in describing and interpreting the data in his tables. Questionnaire and covering letter used in the study is appended. (Contains 16 tables and 19 footnotes.) [Best copy available has been provided.]
