ABSTRACT: “Cultural understanding” can be defined more precisely than teachers generally do. Seven different purposes which classroom cultural activities can illustrate are outlined. Four purposes show that a culture is an interrelated system of patterns which are maintained because they work; that is, because they relate to each other in a way which enables the society to achieve its needs. A fifth purpose concerns student skill in finding out about another culture, and still another relates to the ability to evaluate a statement an American makes about a culture. The seventh purpose probes the area of attitudes which the teacher may want the student to develop. The usefulness of specific activities (over thirty are described) to achieve these purposes can be increased if the activity is described in terms of student performance rather than in terms of content which the teacher hopes to cover. A performance objective has three principal components: (1) an explicit series of statements describing what the student should be able to do after learning what the teacher wants him to learn, (2) the conditions under which the student is to present evidence of having learned it, and (3) the level of student performance which the teacher will accept as evidence of learning.
