The plea of this bulletin, the second and full revision of The Problems Approach and the Social Studies copyrighted in 1955 and 1960, is for teachers to do more with the reflective method in their classrooms. It draws upon the latest and most pertinent insights distilled from research, theory, and practice associated with reflective thinking; deals with specific whats, whys, how, and whens of problem solving in social studies at the elementary and secondary school levels; and, makes a case for increased use of this inquiry method and type of program organization. Specific suggestions are offered that range from the question-answering stage to full-fledged problem-solving units. Chapter 1 by Maurice P. Hunt and Lawrence E. Metcalf introduces the reader to the theory, philosophy, and psychology of the problems approach. Fannie R. Shaftel, Charlotte Crabtree, and Vivian S. Sherman discuss problem resolution in the elementary school. The third chapter on the junior high school is provided by William E. Gardner. Robert E. Jewett treats the senior high school. Trends in the use of reflective teaching, the subject of chapter 5, have been identified and analyzed by Emily S. Girault. Chapter 6 on teaching resources has been prepared by Jack W. Miller.
