Research On The Development Of Blended Learning Cases Of Junior Middle School Mathematics Under The Background Of "internet+"

In the "Internet+" era,the development of information technology has also accelerated the innovation of education and teaching methods and concepts.The single mode of traditional junior middle school mathematics classroom teaching has brought many problems,and the single online learning mode also has defects such as difficulty in supervision.The advantages of the two single models complement each other,coupled with the promotion of education reform,blended learning is developing rapidly as an emerging teaching method combining online and offline.Based on the relevant literature and implementation status of junior middle school mathematics blended learning,this research designs the basic process of the development of junior middle school mathematics blended learning cases,and develops specific cases of blended learning in the four curriculum content areas of junior middle school mathematics based on the process,and proposes related suggestions for its implementation.The main questions of this research are as follows: 1.What is the current status of the implementation of blended learning in junior middle school mathematics under the background of "Internet+" ? 2.Based on the implementation status,how to develop a blended learning case of junior middle school mathematics? 3.What are the suggestions for the implementation of blended learning cases in junior middle school mathematics under the background of "Internet+" ? This research adopts a research method that combines quantitative data and descriptive summary analysis,and obtains research conclusions and suggestions through literature method,questionnaire survey method,interview method,and case method.First of all,this article uses the literature method to read and sort out the related literature and materials of blended learning,determine the survey dimensions and specific questions of this research,and form a complete questionnaire on the status of the implementation of blended learning in junior middle school mathematics.A total of 205 mathematics teachers from 14 junior high schools in Gansu Province were selected as the survey subjects.181 valid questionnaires were used to conduct a statistical analysis of the implementation status of blended learning using SPSS software and a difference analysis of the actual implementation status of blended learning based on demographic variables,Combined with the interview data of 14 mathematics teachers in the junior high schools studied,and further obtained the statistical results of the implementation status of the blended learning of middle school mathematics under the background of "Internet+" : the popularization of blended learning of junior high school mathematics is relatively high but the implementation coverage rate is low,Students have limited hardware equipment for online learning,but teachers use various types of network platforms and are willing to implement them.After analysis,the specific implementation of blended learning in junior middle school mathematics can be described in five dimensions,namely,classroom evaluation management,teacher attitudes,teaching link reconstruction,network technical support and curriculum content design,taking into account teacher demographic information,that is,the school The location,gender,age,teaching age,and professional title of the teacher,the difference analysis shows that the location of the school has significant differences in five dimensions,that is,there are differences in the implementation of urban schools,urban-rural schools,county schools,and rural schools.Regional school hardware equipment and students’ home Internet conditions are quite different,and the development of educational resources is unbalanced,which directly affects the implementation of blended mathematics learning in junior high schools.Immediately afterwards,based on the above related literature and the results of investigation and analysis,this paper designs the basic process for the development of blended learning cases in junior middle school mathematics: 1.The selection of the case theme;2.The structure of the case process;3.The presentation of the case design;4.Comment and analysis of case design.Based on this,a specific case of blended learning for the four types of curriculum content of "number and algebra","graphics and geometry","statistics and probability" and "integration and practice" in the three grades of junior middle school mathematics has been developed: "Real Numbers","The Nature of Isosceles Triangles","Statistical Investigation" and "Subject Learning Pattern Design" and compared blended learning with traditional classrooms.Finally,based on the survey results,teaching case design process and content,six implementation recommendations for hybrid teaching cases are proposed:1.Develop online resources and expand the resource space of blended learning.2.Design classroom activities to enrich the offline links of blended learning.3.Strengthen monitoring and evaluation and feedback the learning situation of blended learning.4.Increase effective interaction and improve the teaching effect of blended learning.5.Seek Parents support to ensure the long-distance effectiveness of blended learning.6.Adjust the implementation content of blended learning accordance with the actual situation of the school.
