在教学中常常发现许多学生在碰稍难一些的数学题时会觉得“无从着手” ,找不到解决问题的途径 .其中一个很突出的问题就是不善于“联想” .爱因斯坦有句名言 :“想象力比知识更重要…” .想象力是借助联想培养起来的 ,联想是由某种概念引起其它相关概念的心理过程 ,是客观事物 In teaching, it is often found that many students find it difficult to solve the problem when they encounter difficult math problems. One of the most prominent problems is that they are not good at “association.” Einstein has a famous saying. : “Imagination is more important than knowledge...”. Imagination is cultivated by associations. Lenovo is a mental process that leads to other related concepts from a certain concept. It is an objective thing.
