教学目标是教师从事教育活动的灵魂,是课堂教学的方向,也是判断一节课是否有效的依据.任何数学教育活动都要围绕着目标进行.数学新课程中强调个性化、生成性目标,因此,用新的理念、新的理论、新的方法,更加科学化,规范化,具体化地去分解、设计教学目标有着重要的意义. Teaching goal is the soul of teachers engaged in educational activities, is the direction of classroom teaching, but also to determine whether a lesson is valid basis for any mathematical education activities should be centered around the goal .Mathematical new curriculum emphasizes personalization, generative goals, therefore , With new ideas, new theories, new methods, more scientific, standardized and specific to the decomposition, the design of teaching objectives is of great significance.
