Research On The Application Of Blended Teaching In The Teaching Of Conical Curve In Senior High School

With the development of educational informationization,a large number of online teaching resources have emerged,and Internet teaching has attracted a large number of experts and scholars to explore and study.At the same time,the new curriculum reform has put forward new requirements for high school education.It is difficult to meet the requirements of modern education development only by relying on traditional offline teaching,which forces educational researchers to explore new teaching methods.Online teaching has the advantages of flexibility and abundant resources,but it lacks direct face-to-face communication and interaction,and an active and infectious classroom atmosphere.Blended teaching combines the advantages of online and offline teaching,and has the characteristics of strong flexibility,rich resources,direct interaction and strong atmosphere,so it has become a hot spot in education and teaching research.Based on the theory of blended teaching mode,this paper studies blended teaching,and takes the contents of the conic section of mathematics in senior middle school as an example.The questionnaire was designed from the aspects of pre-class preview effect,classroom teaching mastery,the degree of conformity of lecture content to students,the completion of homework after class,interactive feedback mode and the teaching experience of online teaching during the epidemic period,so as to understand the current situation of students’ learning about conic content,the difficulties of teachers’ offline teaching in this chapter,and analyze the willingness of teachers and students to adopt blended teaching.After analyzing the results of the questionnaire survey,we know that it is difficult for students to learn the content of conic curve,the classroom teaching content is not fully mastered,the implementation of missing and filling vacancies is not in place,and the channel of obtaining learning resources is single.We also know that teachers have difficulties in taking care of all students,lack of pertinence,untimely feedback,and difficulty in achieving the expected results when teaching offline in this chapter,and try to use blended teaching to propose solutions to the above problems.The analysis shows that blended teaching is in line with the characteristics of high school students’ curiosity and love to contact with new things,so it can arouse students’ enthusiasm for learning.Rich online resources can meet the needs of students’ leak checking and diversified learning,and also provide convenience for teachers to carry out personalized teaching.Online homework and homework completion statistics improve homework correction efficiency and feedback efficiency.Therefore,teachers and students are willing to actively try blended teaching to solve the existing problems in current teaching.At the same time,the questionnaire also investigates the difficulty of carrying out blended teaching for senior high school mathematics teachers.It is found that for most senior high school mathematics teachers,it is generally difficult to carry out blended teaching.After practice,teachers can skillfully use blended teaching to carry out teaching activities.Therefore,the application of blended teaching mode in senior high school conic teaching conforms to the wishes of teachers and students and is feasible.The blended teaching mode is designed for each stage of mathematics teaching in senior high school.Taking ellipse and its standard equation as an example,the blended teaching cases are designed from three stages: before class,during class and after class.It is hoped that the blended teaching mode will be applied to the teaching process concretely.According to the specific blended teaching cases,the operability of blended teaching in senior high school mathematics teaching will be analyzed.It is hoped that through the organic combination of online and offline teaching methods,students’ enthusiasm for learning conic curve will be aroused,students’ ability to think independently and explore knowledge cooperatively will be improved,and good learning experience will be gained,so as to enhance their confidence in learning mathematics well.
