以“模糊”与“精确”的视角“看”高三数学教学会有不一样的风景。在高三数学复习中,笔者尝试用“精确”与“模糊”视角来观察、研究、指导数学教学,取得了满意的教学效果。所谓“精确”就是寻找高三数学复习中客观存在的确定性要素与可操作的手段及步骤,不断优化数学解题的路径与规律;“模糊”就是教师在对学生、教材与高考精确把握的基础上,有意识地运用模糊理论
To “fuzzy ” and “accurate ” perspective “see ” high school mathematics teaching will have a different landscape. In the junior high school mathematics review, the author tries to observe, study and guide the mathematics teaching with “accurate” and “fuzzy” perspective, and has achieved satisfactory teaching results. The so-called “exact ” is to find the high school mathematics review objective existence of certainty elements and operable means and steps, and constantly optimize the path and law of mathematical solution; “fuzzy ” is the teacher in the students, teaching materials and the entrance examination Accurate grasp of the basis of the conscious use of fuzzy theory
