现在小学数学教育中,主题图是教材中的一大特色,把新的教学内容和理念隐藏在主题图中,使得教材中的知识点变少,但是学生的思维空间却变大了。这种教学方式改变了教师传统的教学,为教师带来了更为优质的教学资源。这种改革使得专家教师作用尤为重要,新手教师需要更多的时间才能够成长为专家教师,因此围绕新手和专家教师的对比,成为这种改革的关键。 Now in primary school mathematics education, thematic maps are one of the major characteristics in teaching materials. The new teaching contents and concepts are hidden in thematic maps, which makes the knowledge points in the teaching materials less, but the thinking space of the students is larger. This teaching method has changed the traditional teaching of teachers, bringing more quality teaching resources to teachers. This kind of reform makes the role of expert teachers especially important. Novice teachers need more time to grow into expert teachers. Therefore, the key to such reform is to revolve around the comparison between novice and expert teachers.
