长期以来,我们的数学教学十分强调严密性。教师在授课中最忌出现所谓“科学性”即不严密的错误。在各地频频进行的优质课评选中,教师因一句话不严密而全盘遭否者不乏其人,致使许多教师在本不够严密的初中数学领地里战战兢兢地、逐字逐句地寻求一种艰难的自我完善,授课时语言“规范”、枯燥,不敢越雷池一步。 For a long time, our mathematics teaching has emphasized strictness. In teaching, teachers are apt to avoid the so-called “scientific” that is not strict errors. In the selection of high-quality assessments frequently performed in various places, teachers were not particularly lacking in utterance because of a lack of punctuality. As a result, many teachers found themselves struggling to find a difficult self-improvement in the tightly-knit junior high school math territories. When teaching, the language is “normative” and boring, and she dare not go overboard.
