We have been developing Japanese conversation materials for beginners class. We pick up and classify the items of various expressions for communication which are needed for a natural conversarion. As one of the classification bases, we thought it important how long it takes to teach these items in class. Under the same teaching plan, we gave lessons in two classes and examined its result. The result shows that it takes a long time to teach a) Grammer related items mainly because of its oral practice, b) items, the usage of which must be changed according to the situation.
