认真听讲、积极思考、动手实践、自主探索与合作交流是学生学习数学的重要方式。德国教育学家海因里希教授的实验指出:人对学习内容的吸收,如果仅是听和看的话,只能吸收50%;若能加上动手实践的话,则能吸收90%。在小学低年级数学教学中,教师要重视引导学生动手实践,培养学习兴趣和主动探究意识,在多种感官的协调参与下发现 Listening carefully, thinking positively, hands-on practice, independent exploration and cooperation and exchange are important ways for students to learn mathematics. The German pedagogic professor Heinrich’s experiment shows that people can only absorb 50% of their learning content if they only listen and watch, and can absorb 90% if they can add hands-on learning. In the lower primary mathematics teaching, teachers should attach importance to guide students to practice, develop interest in learning and active exploration of consciousness, found in the coordination of multiple senses
