A self-concept test was developed for use in a mathematics course for prospective elementary teachers in which a master learning approach was being tried. The 27-item test contains two scales that measure (1) satisfaction and (2) change in the way the subject feels with respect to each item. Coefficient alpha reliabilities were .86 for Scale I and .88 for Scale II when the test was given to 250 subjects. Factor analysis produced subtests of self-concept related to Class Participation, Doing Assignments, Confidence in Class, Independent Study, and Attitude. The use of these factors to measure specific effects of instructional programs is proposed. (Author)
