In April, 1919, at the request of the Board of Education of Memphis, Tennessee, the United States Commissioner of Education submitted the conditions on which the Bureau of Education would make a survey of the public school system of that city. This study of the Memphis schools is intended to be a study of policies and practices; not of persons. The report is issued in seven separate parts for general circulation. A summary of conclusions and recommendations will be found at the end of each chapter. Topics covered in Part 4 include: (1) Science in the elementary schools (science related to other subjects; supervision needed); (2) Science in the Central High School (in the curriculums; pupils taking science; sequence of courses; quality of teaching; more teachers needed; the science equipment); (3) Science in the Vocational High School (quality of teaching; a plan of science work needed); and (4) Science in the Kortrecht High School (Colored). (Contains 4 tables.) [For Parts 1-3, see ED541284-ED541286. For Parts 5-7, see ED541288-ED541290. Best copy available has been provided.]
