Some third year high school students find it difficult to learn physics.Because of today’s increasingly fierce competition in science and technology,it is of great significance for the future development of senior three students,which means more attention should be paid to help them learn physics and improve their physical achievement and cultivate their interest in physics learning.The transformation of physics teaching mode in senior three is imminent,while the application of physics micro-course in senior three of middle school is not extensive.Relatively speaking,key senior middle school in the city has complete software and hardware,abundant teaching resources such as micro-lessons.Students have many opportunities to use electronic devices such as smart-phones,tablets and computers.Therefore,the application of micro-lessons in senior three classes has a sufficient hardware and software foundation.It is for this reason that the practical exploration of the application of micro-lessons in Physics Teaching in Senior Three has become an urgent problem to be solved in senior middle school.Based on the analysis of the relevant literature on the application of micro class and the two consecutive senior three teaching experiences,the author actively practices and explores the application of micro class in the review class of senior three.In order to continuously explore the application of physics micro course in senior three,the research process runs through the first and second rounds of review in senior three.Taking the application of electromagnetic induction in micro class as an example,the author evaluates the students’ mastery of the knowledge points involved in the micro class,and then makes a careful analysis of the evaluation results to draw relevant conclusions.The results show that students need to take micro courses at the entrance examination center.Accurate entry point can help senior three students improve their performance.Therefore,considering the actual conditions and learning outcomes of third year high school students,we first analyze the important knowledge points of the college entrance examination,then screen out high-quality micro courses with strong pertinence,and then grade the micro courses for the exam points according to their difficulty levels.We have created micro course application reminder cards,and choose to use them before,during,or after class based on their difficulty levels.After one round of review and two rounds of practical exploration in the third year of high school,and through data analysis,students’ physics scores have significantly improved.Finally,suggestions were put forward for the application of physics micro courses in the third year of high school,and the research process was reflected in the hope of finding more effective ways and methods for the use of micro courses in the third year of high school. |
