数学《课程标准》中提出:“通过义务教育阶段的学习,学生要能初步形成反思意识,形成实事求是的态度以及进行质疑和独立思考的习惯。”反思是一项重要的思维活动,是数学学习的动力。让学生学会反思,对自己的判断与活动甚至语言表达进行思考,并加以证实,能使学生真正深入到数学活动当中,真正抓住数学思维的内在实质,为他们的后继学习积淀经验与方法。 The mathematics Curriculum Standard states: “Through the study of compulsory education, students should be able to form an initial sense of reflection, a realistic attitude and a habit of questioning and thinking independently.” Reflexivity is an important thinking activity Motivation for learning mathematics. Let students learn to reflect on their own judgments and activities and even language expression to reflect and confirm that students can really be in-depth mathematical activities among the real grasp of the inherent essence of mathematical thinking for their successors to learn accumulated experience and methods.
