数学核心知识在知识体系中处于中心位置,具有聚合、辐射、激活等作用。然而,由于数学核心知识多以静态的方式隐藏在知识体系中,所以需要我们教师发掘核心知识的教学价值,使其固有的作用得到应有的展现与发挥。 Mathematical knowledge in the core knowledge in a central position, with polymerization, radiation, activation and so on. However, because the mathematical core knowledge is mostly hidden in the knowledge system in a static way, it is necessary for our teachers to excavate the teaching value of core knowledge so that its inherent function can be properly displayed and exerted.
