Research On Mathematical Micro-course In High School Based On PBL Mode

Micro-lecture teaching based on PBL model is an emerging teaching method,which plays an important role in cultivating students’ autonomous learning consciousness and problem-solving ability,which has attracted great attention and been deeply studied.At present,there are a series of important research results in this area,but the research on the PBL model of high school mathematics micro-lesson teaching is not perfect,and some problems need to be further explored.In this paper,the method of interview and questionnaire survey was used to investigate the mathematics teachers and students of a senior middle school in Ru zhou City.It was found that some senior middle school mathematics teachers’ understanding of PBL mode and micro-lesson teaching is still very weak,and the education concept needs to be updated;The overall level of the students varies greatly,and it is difficult to implement the PBL model of senior middle school mathematics micro-lesson teaching for all students;Students are generally looking forward to improving the existing mathematics teaching methods,hoping to have more opportunities to explore the formation of knowledge.According to the findings of interviews and questionnaire analysis,and based on the discovery learning theory,the innovation education theory,and the deep integration theory of information technology and curriculum,this paper puts forward the teaching practice strategy of high school mathematics micro-lecture based on PBL mode from three aspects of education concept,learning mode and teaching process.In addition,taking the ‘exponential function’ in Section 2 of the fourth chapter and the ‘function y=Asin(ωx+ψ) in Section 6 of the fifth chapter as examples,the micro-lecture teaching of senior middle school mathematics under the guidance of PBL mode was designed and implemented.Practice has proved that the reasonable application of PBL model in micro-lecture teaching can improve the teaching efficiency and strengthen teaching effect both in classroom teaching and online teaching.
