Research On Plane Vector Classroom Teaching Strategy And Practice Based On Problem-Driven

"General High School Mathematics Curriculum Standards(2017 edition,revised in 2020)"points out that it is necessary to improve students’ interest in mathematics learning,cultivate students’ ability of independent learning,and develop students’ core quality of mathematics.This requires teachers to attach importance to the principal position of students in the process of mathematics teaching,guide students to actively participate in the exploration of problems,and cultivate the necessary ability of students in mathematics learning.As a bridge between algebra and geometry,plane vector knowledge contains a wealth of mathematics core literacy,which is an important content in high school mathematics that cannot be ignored.With problem as the core,problem-driven teaching method can give full play to students’ principal position,enable students to experience the process of knowledge generation in communication and exploration,and improve their ability to analyze and solve problems.Firstly,this study uses literature research method to consult and learn the domestic and foreign research results of problem-driven teaching and plane vector.Secondly,questionnaire survey is used to understand the current situation of teachers’ mathematics teaching and students’ problem solving and reflective consciousness.Interview method is used to understand teachers’ understanding of problemdriven teaching method,and the results of survey and interview are sorted out to summarize the problems existing between teachers and students.Thirdly,text analysis is used to sort out the teaching requirements,the contained thought methods and the core literacy of mathematics of plane vector,and combining with the teaching principle of problem-driven teaching method,the paper puts forward the problem-driven classroom teaching strategy of plane vector.Then,with the help of experimental research method,the control class and the experimental class in the practice school were selected to carry out the teaching practice of plane vector under the traditional teaching method and the problemdriven teaching method respectively.After the teaching practice,the students’ problem awareness and pre-test and post-test mathematics scores were investigated.Finally,by analyzing the survey results of problem awareness of students in two classes and using statistical analysis method to analyze the pretest and post-test math scores of students,the effectiveness of problem-driven plane vector classroom teaching is tested.By observing the classroom performance of the students in the two classes in teaching practice and analyzing the problem awareness of the students in the two classes after teaching practice and the survey results of math scores before and after testing,it is found that the problem-driven plane vector classroom teaching can attract students to actively participate in the classroom interaction,and most students can actively think and explore the problems in the classroom.Students’ awareness of problem solving and problem reflection has been improved significantly,and math scores have also made good progress.
