| With the development of Internet technology,blended learning was born and gradually popularized in China’s education.In recent years,under the tide of education reform,the hardware facilities in compulsory education in various regions have been continuously improved,and the teachers’ educational ideas have been updated closely.Multimedia teaching tools have been tried in primary and secondary schools,and blended learning has been applied and implemented in junior high schools.However,due to the fact that the popularity of educational hardware has not yet reached the full coverage per capita,and the junior high school students do not have enough self-management ability to supervise and track,the application of blended learning is mainly limited to some schools and some public demonstration classes,and the widely used area is still the higher education stage.Affected by this,among the research results from 2000 to 2019,the research results of blended learning in the field of education show an increasing trend year by year,but they are mainly concentrated in the higher education stage,involving mainly the concept research of blended learning,the discussion of teaching strategies in the learning process,the application analysis of learning tools,the educational teaching ideas embodied in the implementation,and the effectiveness exploration of learning results,etc.There are only a few small sample studies on a certain software or method in the application research results of junior high school.During the outbreak of COVID-19 in2020,according to the notice spirit of the Ministry of Education of "stopping classes and learning",and combining with local learning resources,the distance teaching class of "Guizhou lessons in the air" was carried out,which cooperated with offline teaching.During this period,blended learning has been widely applied in practice: the number of participating teachers has increased,the objects of practical application are complicated,and the application methods are diversified.This makes it possible to ensure the universality of the sample when studying the application of blended learning in junior high school history teaching.In the process of implementing this research,two groups of junior and second grade students and teachers were selected from two schools with different degrees in the region,and these two schools and related teachers participated in this large-scale mixed learning.The applied research mainly discusses the effectiveness,high efficiency,individuation and attraction of blended learning in each stage of junior high school history teaching.The main methods used are investigation and interview.Among them,aiming at the validity,we examine it from subjective and objective angles by using related papers and questionnaires,and quantify the key behaviors with the core literacy of history as the standard.Through statistical data and comparative analysis with the control group,this paper summarizes that blended learning plays an important role in promoting the balanced development of resources in compulsory education between regions,improving teachers’ professional ability,improving junior high school history teaching efficiency,and enhancing regional ability to resolve risks,etc.,and analyzes the shortcomings in the implementation process,such as the inability to fully display curriculum individuation,the inability of teachers and students to deal with learning feedback in time,and the inability to fully reflect students’ subjective status,and puts forward suggestions for improvement.Finally,the application research direction of blended learning in junior high school history teaching is prospected,and the further research contents need to move forward in the direction of teacher application research,blended learning with more common teaching tools and effective classroom management. |
