| The 21 st century is an era of science and technology continuous enhancement,rapid economic development and increasing cultural diversity.Traditional science education has been unable to keep up with the requirements and trajectory of the development of the new era.A more complete system,key competence,emerged.In order to improve their international status and educational ability,the world has issued documents on the key competence one after another."Key competence" has become a trend and hot points in today's world.This article is a detailed study of primary school science teaching and practice based on the analogy study of Chinese and American key competence system.Chapter one,introduction.The background,current situation and significance of the research are briefly described.The second chapter mainly introduces and analyzes the Chinese and American key competence system.Firstly,by collecting relevant literatures,we elaborate the connotation,the frame structure and the theory foundation respectively.Secondly,the system of China and the United States is analyzed by analogy from similarities and differences,and then the key competence system of the United States and China is integrated by referring to the literacy that is prominent in the "21st century skills" of the United States and that China does not have or has not developed well.The third chapter,based on the key competence system of primary school science education investigation and practical research.Firstly,from the perspectives of students and teachers,questionnaires and interviews are used to understand students' cognition of key competence.Secondly,we conduct practical research on primary school science education under the key competence system from teaching case design and analysis and teaching effect evaluation,mainly applying the integrated key competence system to the case teaching of primary school science,and then make a comparative analysis of the teaching effects of parallel classes and experimental classes.The fourth chapter analyzes the difficulties and countermeasures of the implementation of primary school science education under the key competence.Chapter five,conclusion.We mainly expound from Mainly summary and prospect.Firstly,we summarize the research work.Secondly,the innovation of the research is put forward.Thirdly,point out the deficiency of the research.Finally,point out the direction that future work should strive for. |
