《义务教育数学课程标准》提出:教学活动必须建立在学生的认知发展水平和已有的知识经验基础之上。教师应激发学生的学习积极性,向学生提供充分从事数学活动的机会,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,获得广泛的数学活动经验。因此,在实际教学过程中,教师应引导学生从学习主人翁的角度提出问题、理解问题,形成解决问题的一些基本策略,探索出解决问题的有效方法,体验解决问题策略的多样性,从而促进学生数学思维能力的发展,发挥学生的主体性,更有助于数学的建构性学习和学习方式的转变,对促进学生的发展具有积极意义。
“Compulsory education mathematics curriculum standards” put forward: teaching activities must be based on the level of cognitive development of students and existing knowledge based on experience. Teachers should stimulate students’ enthusiasm for learning and provide students with opportunities to fully engage in math activities so as to help them understand and master basic math knowledge and skills, mathematical ideas and methods, and acquire extensive math activities during their own exploration and cooperation. experience. Therefore, in the actual teaching process, teachers should guide students to raise questions, understand problems and form some basic strategies to solve the problems, explore effective ways to solve the problems and experience the diversity of strategies to solve the problems so as to promote students’ The development of mathematical thinking ability, giving play to the subjectivity of students, but also contribute to the constructive learning of mathematics and the transformation of learning styles, to promote the development of students has a positive meaning.
