“一线串珠”法就是通过某些“实验”、“实物”为线索,提出问题,应用相应的知识解决问题。在解决问题的过程中,要善于找出其知识点及知识结构,以点代面,由此及彼,举一反三,把各知识点有机的形局一体,从而达到 The “first-line beading” method uses certain “experiments” and “real objects” as clues to ask questions and apply relevant knowledge to solve problems. In the process of solving problems, we must be good at finding out their knowledge points and knowledge structure. We must use point-to-face methods to achieve this. We must, in turn, combine the organic shapes of all knowledge points in order to achieve
