Like many education reform advocates, we are not accusing the old textbooks of being bad. In fact, good and bad are relative terms, and depend on whether other choices exist. And no textbook can be perfect, since they are only learning tools.
和許多贊成教科書開放的人士相同，我們並不是認為原來教科書編得不好，事實上，好與不好原本就是比較和選擇下才產生出來的。
