课堂教学是动态生成的,课堂中的不确定性蕴涵了丰富的生成性。教师应该灵活地根据教学情况的变化不断调整自己的教学,在学生的真实认知点上综合把握,应情境而变,应学生而动,敏锐捕捉不期而至的生成点,才能构建真实有效的数学课堂。一、在困惑中生成苏霍姆林斯基说过:“教育的技巧不在于能预见到课堂上的所有细节,而在于根据当时的具体情况,巧妙地在学生不知不觉之中做出相应的变动。”课堂教学中,哪怕预设再充分,由于学生的不同、教学环境的变化以及 Classroom teaching is dynamically generated, and the uncertainty in the classroom implies rich generativeness. Teachers should flexibly adjust their teaching according to the changes of teaching situation. They should grasp synthetically from the real cognition of students and change from circumstances to students. When students move and keenly catch the unexpected generation points, they can build a real and effective Math class. First, in the confusion generated Suhomlinski said: “The trick of education is not to be able to foresee all the details of the classroom, but rather according to the specific circumstances at the time, cleverly made in the students unconsciously The corresponding changes. ”Classroom teaching, even if the default fully, due to the different students, the teaching environment changes and
