Case Study Of STEM Curriculum In American Elementary Schools

With the rapid development of science and technology in the 21 st century,STEM education is sought after and valued by countries all over the world,and my country is no exception.At present,there has been some research on STEM education in primary and middle schools in China,but the "White Paper on Chinese STEM Education" mentioned that there are almost no computer programming subjects in primary and secondary schools.Today,with the rapid development of science and technology,robots have gradually entered all aspects of our lives,and students are very interested in learning and understanding robots.However,judging from the literature and case analysis,domestic LEGO robot STEM curriculum design is in its infancy,and relevant educators have little research on the LEGO robot STEM curriculum in primary schools and have not yet conducted in-depth research.Because the United States has a relatively mature STEM curriculum design model,and the theoretical research and practical research are relatively mature,at the same time,the cognitive development of American primary school students in grades 4-5 and Chinese primary school students in grades 5-6 is between the specific computing stage and the formal computing stage.Have certain abstract thinking and problem solving skills.Therefore,this study adopts literature research method,expert survey method,questionnaire survey method and case analysis method to conduct research,through Taylor principle,Dick and Carey teaching design model,Bloom classification teaching target,American 6E teaching model and evaluation index system The construction principle attempts to construct a case analysis framework for STEM courses,and constructs a case evaluation index system for STEM courses based on the case analysis framework for STEM courses.Therefore,the author selects and analyzes 10 Lego robot STEM course cases in grades 4-5 of American primary schools,summarizes and summarizes the advantages and disadvantages of STEM course design,and provides reference for my country.Through sorting out the cases of Lego robot STEM courses in grades 4-5 in American primary schools,the advantages of course design are as follows: first,the implementation of the course,based on the engineering design process;second,the content of the course,focusing on the course content and real life Close contact,the course content is integrated and practical;third,in the course evaluation,the classroom embedded evaluation is used and the evaluation runs through the entire teaching process;but there are also deficiencies,including the lack of use of communication and collaboration tools and the single teaching environment,neglected Cultivate students' ability to use information technology to retrieve and collect information autonomously.The method of classroom introduction lacks novelty and expands some content without specific implementation.Therefore,based on the advantages and disadvantages of STEM curriculum design,the author takes its essence and removes its dross,and combines the "Chinese STEM Education White Paper" and "Chinese Student Development Core Literacy" to explore the process of learner analysis,game introduction,and engineering design.,Achievement sharing,embedded evaluation,reflection and expansion of six links trying to build a framework for the design of LEGO robotic STEM curriculum suitable for grades 5-6 in China's elementary schools,to provide Chinese primary school teachers and educators with LEGO robotic STEM curriculum design ideas.
