学校における品質工学の集中講義とその成績評価(2)

－成績評価方法の検討－

抄録

Students taking a short course lecture in quality engineering were given problems without correct answers, five proposed criteria were used to grade their performance, and differences among the ratings were studied. The use of the criteria reduced variations in grades given by three instructors and enabled grading differences between the instructors to be reduced. In the calculation of the variation pressure of the grade evaluation, using a unit space constructed by the students with the average grade demonstrated a good agreement with the grading by the criteria. From the study of factorial effects of evaluation items on the variation pressure distance, it appears that grading variations among the instructors can be reduced by evaluating reports in which the students expressed their own ideas in the form of organized text according to the criteria. Evaluating students by using both the criteria and the variation pressure distance could become an advantageous method for many types of scholastic evaluation.
