有意义的数学学习一定是能动的探索过程,不只是手动、口动等显性的活动过程,还要有扎实的脑动过程,使数学学习始终与思维的共鸣伴随。为此,我们要针对教学内容、学生认知储备、经验积累等诸多要素科学地设计学习活动,既让学生的手动起来,也让学生的思维活跃起来,从而使数学活动成为学生消化认知、发展技能、形成经验的有力推手,使数学学习愈加扎实有效,使数学课堂充满智慧,洋溢着快乐。一、课堂写真片段一:探究圆锥的体积与圆柱体 Meaningful mathematics learning must be an active exploration process, not just manual, oral and other explicit process of activity, but also a solid brain process, so that mathematics learning is always accompanied by the resonance of thinking. To this end, we must scientifically design learning activities according to many elements such as teaching contents, students’ cognitive reserve, experience accumulation, and so on. We not only make students manually but also make students’ minds active. As a result, mathematics activities become students’ The development of skills, the formation of a powerful push hands-on experience to make mathematical learning more solid and effective, mathematics classroom full of wisdom, filled with happiness. First, the class photo section one: explore the cone size and cylinder
