小学科学教学具有生动形象的鲜明特征,不仅能够向学生传授理论知识与实践技能,更能在潜移默化的过程中提高学生的思维能力,帮助小学生形成正确的价值观与积极的情感态度。鉴于小学生处于特殊年龄阶段,其理解力、领悟力尚存在一定欠缺,难以直观把握科学知识,因此,图例在小学科学教学中的应用具有十分重要的意义。 Primary school science teaching has a vivid image of the distinctive features, not only to teach students theoretical knowledge and practical skills, but also in a subtle process to improve students’ thinking skills, to help pupils form the correct values ​​and positive emotional attitude. In view of the fact that pupils are in special age stage, their understanding and perception are still lacking and it is difficult to grasp scientific knowledge intuitively. Therefore, the application of lexicon in primary science teaching is of great significance.
