数学教学,从本质上讲,是发散思维活动的教学,怎样依据问题的显条件、题断与发掘出的隐条件多方向、多角度地拓宽思维渠道,创造性地寻求新数学模型,准确、快速地解答问题,这应该是每个数学教师潜心研究的问题。 Mathematics teaching, in essence, is the teaching of divergent thinking activities, how to broaden the way of thinking in a multi-directional and multi-perspective manner according to the explicit conditions of the questions, the conditions of disjunction and excavation, and creatively seek new mathematical models, accurately and quickly. To answer the question, this should be a problem that every mathematics teacher studies with great concentration.
