It is anticipated that through the course in related art pupils will have gained an ability to choose more suitably those materials and articles of wearing apparel and of home furnishing which involve color and design. It is through understanding certain fundamental principles of art and using them that the everyday art problems can be more adequately solved. The teacher is confronted with the question as to how to develop most successfully this understanding and ability. Shall she proceed from the stated principles to their application in solving problems or shall she start with the problems and so direct their solution that the important principles and generalizations are derived in the process. The present trend in education is toward the second procedure and in keeping with this trend, the elaboration of method in this section is confined to the so-called problem-solving method. When pupils have an opportunity to formulate their own conclusions in solving problems and through the solution of many problems having an identical element find a generalization or principle that serves as a guide in other procedures, experience seems to indicate that they get not only a clearer conception of the principle but are able also to make greater subsequent use of it. In their everyday experiences pupils are continually faced with the necessity for making selections, combinations, and arrangements which will be satisfying from the standpoint of color and design. Before they can select wisely they need some standards upon which to base their judgments and by which they can justify their decisions. Before they can make satisfying arrangements and combinations of material they need judgment skill in determining what to do. They also need principles or standards by which they can determine how to proceed. Finally, they need opportunity for practice so that they may become adept in assembling articles and materials into pleasing and harmonious groupings and arrangements. The more experience pupils have in confronting and solving true-to-life problems under the guidance of the teacher, the greater is the probability that they will have acquired habits of thinking that will enable them to solve successfully the many problems that they are continually forced to meet in life. It might be well to inquire at this point the meaning of the word problem as used in this bulletin. According to Strebel and Morehart[21]--
