实施新课程以来,各科教师越来越重视课程的拓展。教学拓展也似乎成了各科课堂教学的主旋律。无论是示范课还是公开课,教师都会不约而同地在课堂教学的后半程进行教学拓展。如果没有拓展,似乎少了点什么,于是,在课堂教学中能够来上一点教学拓展,就显得非常时尚和流行了。 Since the implementation of the new curriculum, all subjects teachers pay more and more attention to the expansion of the curriculum. Teaching development also seems to have become the main theme of all subjects in classroom teaching. Whether demonstration or open class, teachers are invariably in the second half of the classroom teaching teaching expansion. If you do not expand, it seems that something is missing, so in the classroom teaching can come a little teaching and development, it is very fashionable and popular.
