The purpose of this study is to show one of the important roles of course evaluation. Teachers usually give tests to measure now much effort students made or how much they improved their language skills at the end of the term. However, it is also necessary for teacher to know what and how much contribution the course gave to the students through teaching with the materials. A course evaluation is generally done by a multiple choice of questionnaire. Gathering the results of the answers to each item, we will able to get some profiles of the class, such as the students learning attitudes, and motivation, and the usefulness and degree of difficulty of the materials as a whole. This may help our further teaching, but developing a closer relationship among the components of the questionnaire is indispensable to the effective teaching of the course. From this point of view, the study was done by multiplying the data of the items.
