现代教育理论认为,课堂教学要以学生为主体、以学生发展为主线,教师应成为数学课堂教学活动的组织者、引导者与合作者,为学生提供观察、操作、实践等方面的自主探索和合作交流的机会,培养学生的探索能力和创新精神。而“自主探索”是新课程倡导的最主要的学习方式之一。如何在低年级数学课堂教学中组织有效的自主探索活动呢? According to modern educational theory, classroom teaching should take students as the main body and students’ development as the main line. Teachers should become organizers, guides and collaborators of mathematics classroom teaching activities and provide students with independent exploration and observation in terms of observation, operation and practice. Cooperation and exchange opportunities to develop students’ ability to explore and innovation. And “self-exploration” is one of the most important learning methods advocated by the new curriculum. How to organize effective self-exploration activities in mathematics teaching in the lower grades?
