数学抽象难懂,但它来源于生活,只要充分注意联系学生的生活实际来讲概念,同学们就会感到数学就在他们的身边,从而对学习感到兴趣。上学期我教初一,对这方面比较重视,小同学的学习积极性比较高。在讲“相反意义的量”这一概念时,我不仅举了许多实例,而且发动同学讨论,自己举生活中的实例。有的同学说,工厂里工人师傅,生产合格的产品,记作正的,那么废品就记作负的。还有的同学说,小孩子站在学步车里,朝前走记作正,向后退就记 Mathematical abstract difficult to understand, but it comes from life, as long as the full attention to contact with the student's life, the concept of reality, students will feel math on their side, so interested in learning.
