新一轮的课改明确提出:数学课要追求实效,处处以学生思维的发展为本。数学课堂教学的本色是数学思考,追求数学课堂的深度思维是每一个数学教师追求的目标。深度思维的课堂是思辨的课堂,而思辨的课堂需要留给学生自主探究和自我展示的空间,才能让他们通过思考产生个性化的见解。 A new round of curriculum reform clearly put forward: math class to the pursuit of actual results, everywhere to the development of student thinking. The essence of mathematics classroom teaching is mathematical thinking, the pursuit of mathematical thinking in the classroom is the deep pursuit of every mathematical teacher’s goal. Deep thinking of the classroom is speculative classroom, and speculative classroom students need to be left to explore and self-display of space, in order to allow them to produce personalized insights through thinking.
