题目内容：
Objectives are sometimes stated as things which the instructor is to do; as for example, to present the theory of evolution, to demonstrate the nature of inductive proof, to present the Romantic poets, to introduce four-part harmony. These statements may indicate that the instructor plans to do; but they are not really statements of educational ends. Since the real purpose of education is not to have the instructor perform certain activities but to bring about significant changes in the students' patterns of behavior, it becomes important to recognize that any statement of the objectives of the school should be a statement of changes to take place in students. Given such a statement, it is then possible to infer the kinds of activities which the instructor might carry on in an effort to attain the objectives--that is, in an effort to bring about the desired changes in the student. The difficulty of an objective stated in the form of activities to be carried on by the teacher lied in the fact that there is no way of judging whether these activities should really be carried on. They are not the ultimate purposes of the educational program and are not, therefore,really the objectives. Hence, although objectives are often stated in terms of activities to be carried on by the instructor, this formal statement operates as a kind of circular reasoning which does not provide a satisfactory guide to the further steps of selecting materials and devising procedures for the curriculum.
