The Micro Class In The Background Of “Double Reduction” Enhances The Mathematics Application Consciousness Of Students Practical Research

With the rise of MOOC,Flipped classroom and the promotion of micro class competitions at all levels,micro class has gradually entered the field of vision of front-line teachers,which not only breaks the time-space constraints of traditional teaching,but also supports a variety of learning methods,becoming the "booster" of curriculum reform.The existing micro course research is mostly carried out from the level of Educational technology.In contrast,there is less systematic and in-depth research on micro courses from the level of curriculum and teaching by integrating specific disciplines.At present,practical research on micro courses at home and abroad mainly focuses on the design and application of micro courses.However,the new curriculum standards,accompanied by the implementation of the "double reduction" policy,pay more attention to the cultivation of core nutrients,especially in the first grade of primary school,the cultivation of mathematical application awareness.Therefore,this study reflects on the teaching situation of micro courses,determines the research direction of using micro courses to enhance primary school students’ mathematical application awareness and literacy,sorts out the domestic and foreign research status of micro course teaching,and focuses on how to integrate micro courses to enhance primary school students’ mathematical application awareness and literacy.Based on the constructivist learning theory,the Cognitive load theory and the zone of proximal development theory,this research adopts the literature analysis method,Action research method,text analysis method and interview method.Based on the "double reduction" policy as the background,it takes "Cognition Clock" as an example to integrate micro class and classroom teaching,and carry out the practical research on the micro class teaching model of primary school mathematics guided by the cultivation of application awareness literacy.This research took the first grade of A Primary School in Guilin City,Guangxi as the research object,and carried out three rounds of Action research.After each stage of Action research,the problems occurred in the process were sorted out,the ideas were sorted out,and the next stage was entered after modification and improvement.This study summarizes the classroom observation,interviews,and text data formed throughout the practical process,and explores the teaching mode of micro class teaching to cultivate primary school students’ mathematical application awareness and literacy.On the one hand,the teaching mode of combining micro courses with first grade mathematics classroom teaching in primary school has improved the mathematical application awareness of primary school students,efficiently satisfied their self exploration time,stimulated their learning initiative,and achieved the goal of combining learning theory and practice.On the other hand,after three rounds of Action research,this research finally deduced the adjusted micro lesson teaching model through planning,action,observation,reflection and improvement.Finally,based on practical research results,this study proposes strategies for enhancing elementary school students’ mathematical application awareness through micro courses under the background of "double reduction",and summarizes and prospects the practical research of micro courses in primary school first grade mathematics teaching.This study found that the current implementation process of the integration of micro lessons and classroom teaching in Guilin A Primary School has not achieved the desired results,either in the level of teachers and students or in the level of teaching design.In response to the current problems and difficulties reflected,in order to better enhance elementary school students’ mathematical application awareness through integrated micro course classroom teaching,the author proposes the following optimization strategies: clarifying the teaching situation and clarifying teaching ideas;Create life scenarios and cultivate application awareness;Enhance teachers’ technical application ability and teaching philosophy,etc.I hope to provide reference and inspiration for future researchers in basic education.
