听名师的课,常令听课教师拍案叫绝。但学名师的课,简单模仿却常常事与愿违。原因有二:其一,好课是从教者心灵深处流淌出来的,一堂好课,应该是数学教师全部数学素养在某个特定课堂情境中的自然挥洒。一招一式、亦步亦趋的简单模仿自然只能貌合神离、南辕北辙;其二,名师的示范教学只是告诉教师“可以这样做”而不是“必须这样做”。鉴于此,探寻名师“为什么这样教”或“可以这样教”背后的意义,不仅有利于教师更好地把握名师课堂的精髓,而且对于一线教师而言或许更具借鉴
Listen to the teacher’s class, often make the lecture teacher beat the case. However, the famous teacher’s class, simple imitation is often contrary to expectations. There are two reasons: First, a good lesson is flowing from the depths of the teacher, a good lesson, mathematics teachers should be all the mathematical literacy in a particular classroom situation naturally sway. One by one, one step by step simple imitation of nature can only fit together, diametrically opposed; Second, the teacher’s demonstration teaching just tell the teacher “can do ” rather than “must do ”. In view of this, it is not only beneficial for teachers to grasp the essence of the teacher’s class better, but also to learn more from the front-line teachers in order to explore the significance of the teacher “why to teach ” or “can be taught”
