=B. Curriculum May Become Fossilized.=--A second danger in the use of the school curriculum consists in the fact that, as a representation of social life, it may not keep pace with the social changes taking place outside the school. This may result in the school giving its pupils forms of knowledge which at the time have little functional value, or little relation to present life about the child. An example of this was seen some years ago in the habit of having pupils spend considerable time and energy in working intricate problems in connection with British currency. This currency having no practical place in life outside the school, the child could see no connection between that part of his school work and any actual need. Another marked example of this tendency will be met in the History of Education in connection with the educational practice of the last two centuries in continuing the emphasis placed on the study of the ancient languages, although the functional relation of these languages to everyday life was on the decline, and scientific knowledge was beginning to play a much more important part therein. While the school curriculum may justly represent the life of past periods of civilization so far as these reflect on, and aid in the interpreting of, the present, it is evident that in so far as the child experiences the past without any reference to present needs, the connection which should exist between the school and life outside the school must tend to be destroyed. =C. May be Non-progressive.=--As a corollary to the above, is the fact that the school, when not watchful of the changes going on without the school, may fail to represent in its curriculum new and important phases of the community life. At the present time, for example, it is a debatable question whether the school curriculum is, in the matter of our industrial life, keeping pace with the changes taking place in the community. It is in this connection that one of the chief dangers of the school text-book is to be found. The text is too often looked upon as a final authority upon the particular subject-matter, rather than being treated as a mode of representing what is held valuable and true in relation to present-day interests and activities. The position of authority which the text-book thus secures, may serve as a check against even necessary changes in the attitude of the school toward any particular subject.
