Comparative Study Of Science Textbooks In Primary Schools

With the tide of international basic education reform,it has also promoted the reform of basic science education in China.In the "Compulsory Education Primary School Science Curriculum Standards" promulgated by China in 2017,primary school science classes are required to start from the first grade.Under the new curriculum standards,multiple versions of primary school science textbooks continue to emerge,and the characteristics and quality of different versions of primary school science textbooks have attracted the attention of researchers and front-line teachers.In this paper,the first grade science textbooks of the education science edition,the Jiangsu education edition and people education edition are selected as the research objects,and the three edition of the textbook are compared and analyzed through the literature method,comparative analysis method and statistical analysis method.The research mainly makes a comparative study from the overall knowledge structure of the textbook,the knowledge structure and presentation methods of the four major areas.By analyzing the textbooks,we found that the three versions of the textbooks are rich in sentence patterns.The education science edition and the people education edition use the first person as the master,but the Jiangsu education edition use the second person as the master.In terms of illustrations,The textbooks all use a large number of pictures.The Jiangsu education edition introduces some cartoon characters in the illustrations.They appear in the textbook in the form of a fixed academic companion.In terms of columns,the Jiangsu education edition is composed of several icons.It is not always flexible.The number of columns is small and fixed in people education edition and education science edition,but they are relatively single.In the analysis of the content of the overall knowledge structure,the three editions of the textbook follow the "unit-lesson" structure model,but the number of units and lessons is different.The knowledge structure of the four major fields are different,They are all based on the four major fields of "life science","material science","earth and universe" and "technology and engineering",The amount of domain knowledge has different focuses,mainly in the fields of life science,material science,technology and engineering.On the basis of comparative analysis and in-depth research,this paper suggests.the teaching materials should pay attention to the common development of scientific literacy and technical literacy,the distribution of knowledge in various fields should be more rational,the column presentation should be optimized,Focus on the penetration of scientific history,Pay attention to the mutual reference between teaching materials,Pay attention to the secondary development of teaching materials.
