新课程标准指出:数学教育要面向全体学生,实现人人学有价值的数学、人人都获得必需的数学、不同的人在数学上得到不同的发展。由此可见,在数学教学活动中,学生才是数学学习的主人。作为数学学习的组织者、引导者和合作者,教师在教学中应积极创设问题情境,让学生通过动手操作、自主探索、实践应用等主体活动去亲近数学、体验数学、“再创造”数学和应用数学,真正成为数学学习的主人。一、重问题情境,让学生亲近数学
The new curriculum standard states that mathematics education should be aimed at all students and realize the valuable mathematics for all to learn. Everyone has acquired the necessary mathematics and different people have made different developments in mathematics. Thus, in mathematics teaching activities, students are the masters of mathematics learning. As the organizer of mathematics learning, leaders and collaborators and teachers should actively create problem situations in their teaching so that students can get close to mathematics and experience mathematics through “hands-on operation, self-exploration and practical application”, “re-create” Mathematics and applied mathematics, truly become the master of mathematics learning. First, re-question the situation, so that students close to mathematics
