Research On The Problems And Countermeasures Of Junior Middle School Mathematics Classroom Teaching From The Perspective Of Blended Learning

Since the middle of the 20 th century,with the invention of the Internet and the development of information technology,blended learning emerges as the times require.Blended learning is a mixture of learning methods and a mixture of learning concepts: in the mix of learning methods,it is a combination of online learning and offline learning,and is a combination of traditional learning methods and online learning methods;In the aspect of the combination of learning concepts,the concept that it brings to teaching is that teaching should be oriented to all students,promote students' active learning,realize the unity of students' independent learning and cooperative learning,and pay attention to the development of students' cognitive structure.Under the background of basic education curriculum reform,the aim of junior middle school mathematics curriculum reform is to cultivate students' independence and autonomy,and to promote students to study mathematics actively and individually under the guidance of teachers.That is all coincides with the concept of hybrid learning.In this paper,the author takes Jining junior high school students and teachers as the object of investigation,using questionnaire survey,observation and interview methods to analyze the current situation of mathematics teaching in junior high school classroom.On the part of students,the author designs a questionnaire according to the psychological characteristics of junior high school students,and investigates the current learning situation of junior high school students,.The questionnaire mainly involves four dimensions: individual learning consciousness,autonomous learning consciousness,cooperative learning consciousness,and mastering learning consciousness.And then uses ANOVA analysis in SPSS to analyse questionnaires.On the part of teachers,the author adopts the combination of observation and interview to investigate the teachers' teaching ideas,teaching methods and teaching environment.Through the author's research,it is found that there are two main problems in the present situation of mathematics classroom teaching in junior high school.One is the problems existing in students' learning,including lack of autonomy,lack of pertinence in cooperative learning and backward learning environment;the other is the problems existing in the teaching of teachers,including the unclear role of teachers,the lack of individuality in teaching objectives and the neglect of the students' existing learning basis.In view of these problems,the author suggests that: firstly,the individualized teaching objectives should be customized,including three-dimensional teaching objectives and layered teaching objectives;secondly,the teaching content should be integrated,including online teaching content and offline teaching content;Thirdly,it is necessary to optimize the classroom teaching process,set up the learning guidancelink,carry out the stratified teaching and transform the main body of the classroom summary;finally,we should reform the teaching evaluation,formulate the measurement scale of the learned knowledge,and establish the diversified evaluation system.At the end,taking the image and property of inverse proportional function as an example,the author explains in detail the application of mixed learning method in mathematics classroom teaching in junior middle school.
