数学教学中不仅要给予学生充分操作、探索的时间,还要给学生充分交流合作的机会和方法。讨论是让学生参与教学过程、体现学生主体地位的一种有效的方法。课堂讨论不仅能调动全体学生投入到自我探索的过程中,而且有利于培养全体学生学习的积极性、独立思考的习惯、语言表达能力和合作精神。 Mathematics teaching should not only give students full operation and exploration time, but also give students the opportunity to fully exchange and cooperation methods. Discussion is an effective way to involve students in the teaching process and reflect the dominant position of students. Classroom discussion can not only mobilize all students into the process of self-exploration, but also conducive to the development of all students learning enthusiasm, independent thinking habits, language skills and cooperation.
