Research On The Status Quo And Influencing Factors Of Physics Exercise Teaching In Senior High School

The newly revised curriculum standards in 2017 put forward the core qualities of physics,including physical concept,scientific thinking,scientific inquiry,scientific attitude and responsibility.The study of physics curriculum has put forward a clear goal: to form ideas of matter,motion,interaction and energy,can solve practical problems;Have the consciousness and ability of constructing model,use scientific thinking method to carry on scientific reasoning qualitatively and quantitatively;Have a sense of scientific inquiry,discover problems and design inquiry schemes;Can correctly understand the nature of science.Exercise teaching,as an important part of high school physics teaching,is an important channel to feedback students' learning and test teachers' teaching methods.It plays an important role in deepening and consolidating knowledge and connecting theory with practice.However,from the author's teaching practice,there are some problems in the current exercise class.Students reflect that physics is difficult to learn,will not draw inferences,do the problem can not find the entry point;Teachers treat exercise class not rigorous,do not pay attention to exercise class teaching methods,easy to cause "full of".It is very necessary and of practical significance to improve the current situation of exercise teaching,optimize the teaching mode of exercise class and clarify the goal of exercise teaching in order to achieve the realization of the core literacy of physics.In order to clarify the research ideas,the author firstly sorted out a large number of relevant literatures about physics exercise teaching and teaching influencing factors.The concept of physics course and exercise course is defined.The paper sorted out the literature on the teaching concept,teaching method and current situation of exercises.The influences of teachers,students and other factors on teaching are classified and sorted out,and the research content of this paper is determined as follows:In the first study,some middle school teachers and students in Tangshan were surveyed by questionnaire.From the teacher's point of view to understand the exercise related knowledge,exercise selection,teaching method selection and classroom implementation process;Understand the attitude towards learning,classroom mode,after-class feedback and consolidation,and the teacher-student relationship from the perspective of students.In the second study,a questionnaire survey was conducted on the influencing factors of exercise teaching among teachers and students in some senior high schools in Tangshan city.There are 19 sub-factors in three dimensions: teacher,student and teaching process.By means of statistics and grading,make statistics of percentages and averages and rank them.Through the analysis and conclusion of the questionnaire results,the following conclusions are drawn:There are such phenomena in the exercise class in the area where the survey object is located: teachers have a better grasp of exercise knowledge,and students have a positive attitude towards physics learning;Teachers pay attention to the selection of exercises before class,but not enough attention to the textbook exercises after class.Students' after-school migration is not good,and their modeling ability needs to be improved.Lack of cultivation of scientific thinking and problem-solving methods;The classroom teaching mode is traditional,and the students' main role is weakened.Influencing factors of exercise teaching: On the whole,the influence degree of the three dimensions are teachers(3.50),students(3.48)and teaching process(3.19).The average score of 18 sub-factors is more than 3 points,indicating that it has an important influence on exercise teaching.In order of average score,the two factors with the greatest influence in each dimension are obtained as follows.Teachers: solid and comprehensive subject knowledge is an important object of teaching activities,and a strong sense of teaching responsibility is the spiritual source of teaching work.Students: positive attitude is an important premise of physics learning,and student behavior is an important factor to ensure the completion of teaching tasks.Teaching process: choosing reasonable teaching content is an important premise of exercise teaching,and reasonable teaching method is an important means of thinking training.Through the above investigation on the current situation of exercise teaching and influencing factors,we understand the problems existing in the current exercise teaching,combined with the influence degree of each factor,put forward the following teaching strategies:(1)teachers should comprehensively improve the physical discipline knowledge reserve,correctly recognize the role positioning and professional mission;(2)Stimulate students' learning motivation and help them establish a correct learning attitude;(3)Enrich the teaching mode,stimulate students' interest points,improve the degree of classroom participation;(4)Choose effective teaching content,arrange examples and exercises reasonably;(5)Optimize the method of explaining exercises,systematically train students' thinking ability and problem-solving methods.Finally,the teaching design of "capacitor capacitance" section is designed,and the teaching reflection is carried out from the selection of exercise,teaching mode,exercise teaching method and other aspects.
