近期,笔者所在学校数学教研组就“圆周角”(苏科版《义务教育教科书·数学》九年级上册第二章第4节)的教学开展了一次课堂教学展示与研讨活动。应教研组要求,两位教师分别在两个平行班级进行了“常态课”展示。两节课又采取了截然不同的处理方式,进而引发笔者对数学教学中如何做到“收放有度”的思考,现整理如下,以飨读者。
Recently, the author’s school mathematics teaching and research group conducted a classroom teaching demonstration and seminar on the teaching of “circle angle” (Suke version of “compulsory education textbook · mathematics” ninth grade second chapter fourth chapter) teaching. At the request of the teaching and research group, the two teachers conducted the “Normal Course” demonstration in two parallel classes respectively. Two classes have taken a completely different approach, which led to the author of mathematics teaching how to achieve “retractable degree ” thinking, are now organized as follows to readers.
