《数学课程标准》提出数学教育要以有利于学生全面发展为中心,倡导有意义的学习方式为基本点,在教学中应综合应用多种教学模式,相互补充,形成良好的整体结构.教学模式的多样性,有利于激发学生的认知活动,为能力的全面发展创造条件。只有打造活跃、灵动、有效的课堂,让学生积极参与,自主学习,相互讨论,取长补短,才能让数学教学更为有效。一、让学生多动手,打造活跃课堂. The standard of mathematics curriculum puts forward that mathematics education should center on all-round development of students and advocate meaningful learning methods as its basic points. In teaching, a variety of teaching modes should be applied synthetically to complement each other to form a good overall structure. Diversity, is conducive to inspire students' cognitive activities, and create conditions for the all-round development of their abilities. Only by building an active, agile and effective classroom, allowing students to actively participate in, learn independently, discuss each other and learn from each other can make mathematics teaching more effective. First, let the students more hands-on activities to create an active classroom.
