Research On Precision Teaching Of High School Physics Based On Zhixue Network

In the wave of big data development,the education industry has also ushered in a refined and precise reform."Precision teaching" is an advanced application of the theory of "teaching students according to their aptitude" under the application of educational big data technology.It is the enrichment,refinement and deepening of teaching means.By collecting and sorting out the data of students’ learning situation,teachers can grasp the learning situation more accurately,so as to implement precision teaching.In 2019,the school where the author works introduced the platform of Zhixue.com,which can comprehensively record the educational data generated by each student in the learning process.Moreover,Zhixue.com also has rich question bank resources,which can satisfy teachers to choose questions of different difficulty to assist teaching.Through the data analysis of Zhixue.com,teachers can not only find out the common mistakes and knowledge weaknesses of the whole students in the class,but also know the degree of each student’s mastery of a certain knowledge.This study takes the students of two parallel classes at the same level in Tongliao No.5 Middle School as the research objects,aiming at comparing the differences between the traditional teaching model and the precision teaching based on Zhixue Network.The duration of this study was four months.The author continues to explore the functions of the wisdom network.Combined with the function of Zhixuet.com platform,the author gradually formed the "five-step teaching method" of knowledge point review course with precision teaching as the core and the "four-gradient method" of exercise lecture and evaluation course.In the early stage of this study,the author conducted a questionnaire survey on the status quo of precision teaching among all the senior three science students in our school.Meanwhile,the author also interviewed the senior three physics teachers of Tongliao No.5 Middle School to understand their views and opinions on the precision teaching based on Zhixue Network.At the later stage of the study,the author compared the scores of multiple examinations of the two parallel classes,and also compared and analyzed the physical scores of each student in the experimental class before and after the study.The research results show that: First,using the data analysis function of Zhixue.com,teachers can quickly understand the learning situation of students,which makes teachers not only save time and effort in lesson preparation,but also make the teaching content more accurate.Second,the precision teaching based on Zhixue.com makes students’ physics scores obvious,which can show that the precision teaching has a good effect on the teaching effect.Third,after accurate help for students with learning difficulties,the achievement of students with learning difficulties has also been significantly improved.However,due to the limited ability of the author,there are still limitations in this study,and the author will continue to improve and perfect it in the future.
