《课程标准》指出:要创设与学生生活环境、知识背景密切相关的,又是学生感兴趣的学习情境,让学生在观察、猜测、交流、反思等活动中逐步体会数学知识的产生、形成与发展的过程,获得积极的情感体验,感受数学的力量。不难看出,这段话的核心是要让学生实现数学学习的亲历性,使数学学习成为学生智能成长的过程。 “Curriculum Standard” points out: To create a learning context that is closely related to students’ living environment and knowledge background and is also of interest to students so that students can gradually realize the production of mathematical knowledge in the activities of observation, speculation, communication and reflection, The process of development, access to a positive emotional experience, feel the power of mathematics. It is not difficult to see that the core of this passage is to enable students to realize the maturity of mathematics learning so that mathematics learning becomes the process of students’ intelligent growth.
