小学数学课新程标准指出:数学教学过程应建立在学生的认知水平和已有经验的基础之上。教师应激发学生的学习兴趣,为学生提供充分学习数学过程的机会,帮助他们在自主探索和合作交流的过程中真正理解和掌握基本的数学知识与技能、数学思想和方法,获得广泛的数学过程经验。因此,教师要在继承传统的基础上,把主要精力放在为学生创设学习情境,提供信息交流平台,引导学生积极思维,增强学生的自主意识,提高学生的自主学习能力。一学生利用已有知识,自主学习新知数学是一门逻辑性和系统性很强的学科,在小学数学教学过程当中,教师应把所学的知识作适当的延伸。
The new curriculum standard of primary school mathematics class points out: The mathematics teaching process should be based on the students’ cognition level and the existing experience. Teachers should stimulate students’ interest in learning by providing students with opportunities to fully learn the mathematics process so that they can truly understand and master basic maths knowledge and skills, mathematical ideas and methods in their own exploration and cooperation and exchanges, and obtain extensive mathematical process experience. Therefore, on the basis of inheriting the tradition, teachers should focus their efforts on creating learning situations for students, providing a platform for information exchange, guiding students’ positive thinking, enhancing students’ sense of autonomy and enhancing students’ autonomous learning ability. A student using existing knowledge, learning new knowledge of mathematics is a highly logical and systematic discipline, primary school mathematics teaching process, teachers should be the appropriate extension of the knowledge learned.
