Research On The Design Of Stem Lessons In Primary Schools

With the rapid development of science and technology and the fiercer international competition,countries have accelerated the training of scientific and technological talents.STEM education,which integrates science,technology,engineering and mathematics,has emerged as the times require.STEM education is a cross-border integration of science,technology,engineering and mathematics through engineering design-based learning,project-based learning and problem-solving-based learning.In this paper,STEM lessons in primary schools are studied,relevant literature is read,classical ADDIE model is adopted,mortise teaching is effectively carried out in accordance with STEM education mode,and a "mortise and tenon" STEM course case is designed to fully demonstrate the significance and value of STEM education,stimulate students' learning enthusiasm and improve classroom vitality.The paper is divided into the following five parts:The first part elaborates the research background,purpose and significance,research methods and research status at home and abroad.The second part carries on the theoretical annotation,takes the STEM education related theory as the starting point of the research.From the characteristics of STEM education,STEM education mode,theoretical basis of research three aspects.The third part is the ADDIE model of "tenon and mortise" teaching design.This chapter combines the classical ADDIE model with STEM educational concept to construct the ADDIE model of STEM lessons.The fourth part is the case of "tenon and mortise" curriculum design.This chapterprovides three cases of curriculum design.They are based on engineering design,project-based and problem-based teaching methods,which are applicable to students in the lower,middle and upper grades of primary school respectively.The fifth part is the inadequacy and reflection of the study,to make a summary of this study,and reflect on the inadequacies of the study.
