数学学习应当是一个主动的、活泼的和富有个性的过程。数学的学习方式也不应只是单一的、枯燥的、学生被动听讲和练习的方式,应该是一个充满生命力的过程。新的《数学课程标准》明确指出:有效的数学学习活动不能单纯地依赖模仿和记忆,动手实践、自主探索与合作交流是学生学习数学的重要方式。为了贯彻这一精神,笔者精心设计了“圆的周长”一课,在执教中让学生在学习活动中感悟数学思想,积累数学活动经验,取得了良好的学习效果。
Mathematics learning should be a proactive, lively and personal process. Mathematical learning should not only be a single, boring, passive listening and practice of students should be a process full of vitality. The new “Mathematics Curriculum Standard” clearly states: Effective mathematics learning activities can not rely solely on imitation and memory. Hands-on practice, independent exploration and cooperation and exchange are important ways for students to learn mathematics. In order to carry out this spirit, the author elaborately designed a course named “Circumference of Perimeter”, which enables students to comprehend mathematics thoughts in their learning activities and accumulate experience in mathematics activities and achieve good learning results.
