《数学课程标准》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、合作交流是学生学习数学的重要方式。实践活动是儿童发展,成长的主要途径,也是学生形成实践能力的载体。在数学教学中,教师应注意通过观察操作,猜测等方式培养学生的思维能力,主动参与意识和勇于探索的精神。下面本文笔者就结合自己的教学实践谈谈对“动手实践,发展能力”的体会。 Mathematical Curriculum Standard states that effective mathematics learning activities can not rely solely on imitation and memory. Practical practice, independent exploration, and cooperation and exchange are important ways for students to learn mathematics. Practical activities are the main ways for children to develop and grow, and also serve as carriers for students to form practical skills. In mathematics teaching, teachers should pay attention to cultivate students’ thinking ability, active participation in consciousness and courage to explore through observing operation, guessing and so on. The following author of this article combined with his own teaching practice to talk about “hands-on practice, development ability ” experience.
