义务教育阶段的数学课程,其基本出发点是促进学生全面、持续、和谐的发展。所以教师要着眼于学生的终身发展,课前要深入研究教材,真实了解学生生活经验,找准新知的真正切入点;课上要尊重学生,解放学生的身心,激活学生的思维,引导学生主动建构、形成数学方法,更要注意及时捕捉教学生成,有效引领让学生在做中体验,让数学课堂充满灵动与智慧。本文以一位教师执教的苏教版二年级上册《平均分》一课,加以详细举例说明。一、情境再现 The basic starting point of mathematics curriculum in compulsory education stage is to promote the development of students in a comprehensive, consistent and harmonious way. Therefore, teachers should focus on the students’ life-long development. Before class, they should study materials in depth, truly understand the students’ life experience and identify the real entry point of new knowledge. In class, students should be respected, their physical and mental needs should be liberated, students’ thinking should be activated, students should be encouraged Construction, the formation of mathematical methods, but also pay attention to timely capture the teaching generation, effectively lead students to do in the experience, so that mathematics classroom full of agility and wisdom. In this paper, a teacher taught the second edition of the Soviet version of the “average” a lesson, give a detailed example. First, the situation reproduce
