本文以《正比例的意义》新旧教学设计的对比为载体,结合了笔者对于数学教学中整合目标、关注生活、自我感悟的教学设计的探索和实践,提出了对新《课程标准》下数学教学设计的感悟:整合目标,改偏重于认知结果为偏重于学习的过程;关注生活,改单一的学习内容为重视学习内容的现实性、多维性;自我感悟,改教师传授知识为让学生主动建构知识。 Based on the contrast of old and new instructional design in the aspect of “proportionate significance”, this paper, combined with the exploration and practice of the author’s instructional design in integrating maths teaching, life and self-awareness, puts forward some suggestions on the design of maths teaching under the new “curriculum standards” Perception: to integrate goals, emphasis on cognitive outcomes are more emphasis on learning process; focus on life, to change the content of a single study to pay attention to the reality of learning content, multidimensional; self perception, change the teacher to impart knowledge for students to take the initiative to construct know how.
