[单项选择]The essential weakness of the old and traditional education was not just that it emphasized the necessity for provision of definite subject-matter and activities. These things are necessities for anything that can rightly be called education. The weakness and evil was that the imagination of educators did not go beyond provision of a fixed and rigid environment of subject-matter, one drawn moreover from sources altogether too remote from the experiences of the pupil. What is needed in the new education is more attention, not less, to subject-matter and to progress in technique. But when I say more, I do not mean more in quantity of the same old kind. I mean an imaginative vision which sees that no prescribed and ready-made scheme can possibly determine the exact subject-matter that will best promote the educative growth of every individual young person; that every new individual sets a new problem ;that he calls for at least a somewhat different emphasis in subject-matter presented. Th
A. the rigid school curricula are thoroughly transformed.
