《中小学数学》(初中版)2009年1—2期陈茂林的《一道有“毛病”的课本习题》,内容是陈老师对华师大版《数学》八年级第十四章《勾股定理》复习题中一道题目的修改,陈老师备课的认真细致和对教材文本的深入研究并提出了修改意见我深表敬佩,但是细读陈老师的文章我以为仍有需要商榷的地方。 “Primary and secondary mathematics” (junior high school edition) in 2009 1-2 of Chen Maolin's “one has ” problems “textbook exercises”, content is Chen Normal University version of “Mathematics” eighth grade fourteenth chapter “hook Stock theorem ”review questions in a topic of revision, Chen preparing lessons carefully and textbooks on the in-depth study and proposed amendments to my admiration, but read Chen's article I think there is still room for discussion.
