在我校第四届教育研讨会上,聆听了上海延安中学的李正辉老师执教的《二元一次方程与一次函数》。从整个数学课堂来看,感觉亲切,自然,而又处处彰显出正辉老师的教育智慧。我从教近二十年,听过许多各种级别的公开课,很少有这种“久违了”的感觉。一、“平淡无奇”的新课导入一直以来,公开课都是比较理想的一种教学研究形式,特别是实施课程改革以来,公开课已经成为目前中小学教育教学中一道独特的风景线。课前我们都在猜测,正辉老师会以什么样的方式导入新课?数学史?视频?音乐?亦或是……结果让我们“大失所望”:
At the fourth educational seminar in our school, I listened to the “Binary Equations and Functions” coached by Professor Li Zhenghui at Yan’an High School in Shanghai. Throughout the math class, feeling warm and natural, but everywhere highlights the educational wisdom of Zhenghui teachers. I’ve been teaching for nearly two decades and have heard many open lessons of all kinds and few have this feeling of “returning to the past”. First, “bland ” new course has been imported, open class is an ideal form of teaching and research, especially since the implementation of curriculum reform, open class has become the primary and secondary education in teaching a unique landscape . We were all guessing before class, in what ways did Zhenghui teachers introduce new lessons? History of mathematics videos? Music? Or ... or ... the result disappointed us:
