Development of an evaluation device to measure quality of workmanship on a blouse

The objectives of this study were to develop, test, and revise an evaluation device for quantitatively scoring the quality of blouses constructed by students who learned to sew by following a self-instructional program. The program was developed as part of United States Office of Education research project No. 5-1042. Various kinds of evaluation devices were studied. Since rating scales are most frequently used in areas where measurement is dependent upon observation, a rating scale was selected as the appropriate device for this quantitative scoring of the blouse. A rating scale in dicnotomous form, on which the judge recorded that the blouse was satisfactory or unsatisfactory with respect to each descriptive phrase, was first tried but later discarded in favor of a three-level scale on which judges could appraise eacn construction process by considering several levels of quality. The three-level scale was then subdivided to form a six point scale
