the efficacy of his acts and pauses to reflect, plan, and evaluate before acting overtly. At other times, especially in the lives of less thoughtful persons, such learnings may result from heedless trial and error overt responses or from uncritical acquiescence to suggestion which, like as not, is surcharged with emo tional appeal. Behavior patterns that are intelligent, wise, and in the long run most efficacious are those acquired by the reflective route. Intelligent, capable, self-directing persons are those who recognize the significant problems of action that confront them, who spare time when possible to study and reflect upon such lems, and who have become proficient in the techniques and mental processes involved in such study and reflection. To the degree, then, that intelligent, capable, self-directing persons are desired as products of education, guidance should be offered in the recognition and solution of significant types of practical or action problems. Obviously such guidance to be effective must provide the learners with adequate solving techniques. How ever, not a great deal has been done to per fect techniques for solving the action type of To overcome this handicap and to provide his education classes with a pro cedure for solving teaching the writer has developed the solving technique presented in this paper. For three years the assignments in all of his courses have been in the form of uproblacts,y> a term coined by contraction of the phrase problem of action. term problact is significant, for the recognition of the distinctive nature of the action is an important step in the development of a satisfactory solution tech nique. In a of this type a person is disturbed and hesitates to act overtly, be cause he is uncertain what action is best or most appropriate. Thus the problact belongs to that class of problems which require the use of evaluation for their solution, and which may be distinguished from problems of the fact or science type. Abelson1 and Monroe and Engelhart2 have recognized the need for making this distinction in the field of educa tional research. former refers to lems requiring a consideration of values as evaluative problems, the latter as prob lems of purposes. Dewey, too, has stressed such a distinction by devoting a chapter of Quest for Certainty to a discussion of The Construction of Good. chapter contains the following statement: The time will come when it will be found passing strange that we of this age should take such pains to control by every means at command the formation of ideas of physical things, even those most remote from human concern, and yet are content with haphazard beliefs about the qualities of objects that regulate our deepest interests; that we are scrupulous as to methods of forming ideas of natural objects, and either dogmatic or else driven by immediate conditions in fram ing those about values.3 Another distinguishing feature of the lact is its comprehensive nature, which serves to distinguish it from other kinds of evalua tive problems and from problems of the science type as well. Symonds4 has recog nized this in a classification of problems in which conduct problems are used to illustrate the complete problem. Fact and simple value problems tend to arise incidentally in 1 Harold H. Abelson, Art of Educational Research, pp. 274-77. New York: World Book Co., 1933. 2 Walter S. Monroe and Max D.
