Research On Current Situation Of Physics Precision Teaching In Junior High School

Precision is one of the necessary measures to improve the teaching quality.With the influence of " Internet Plus" concept on the reform and development of education and teaching,it is becoming more and more attention and essential to realize accurate teaching of physics in junior middle school,looking back on the history of teaching,we can find that precision is not only the internal requirement and practical need of improving teaching quality,but also is the call of times for teaching practice of technological innovation.However,if we do not understand the specific situation of junior high school physics teaching,we can not accurately improve its current situation,then,junior high school physics teaching precision can not be achieved.Therefore,in order to study the countermeasure of physics teaching in junior middle school based on precise teaching,we must carry out investigation and research first.Based on the research results of precision teaching,guided by Babanskiy's theory of teaching process optimization,and fully integrating Lev Vigotsky's zone of proximal development theory and Rogers' s humanistic theory,this study designed a questionnaire from five dimensions: pre-class,class,optimization,diagnosis,follow-up and improvement of teaching.A random sampling was conducted among 4 students of grade two and grade three in rural x county,the data were recorded and processed by SPSS software.The results showed that the reliability and validity of the questionnaire(Cronbach's Alpha value was 0.896)and the validity(KMO value was 0.849)are satisfying.The exploratory factor analysis found that the dimensions of the questionnaire constructed by the study were consistent with those of the actual survey.The results show that the second grade students are better than the third grade students in most aspects,and the female students are better than the male students in most aspects.Relevant research found that junior high school physics teaching precision and students' interest in physics learning,learning satisfaction has a significant correlation.In a word,the research shows that there are three main problems in the present situation of the survey sample,the overall implementation needs to be improved urgently,there are significant differences in gender and grade in all levels of implementation,and students' interest and satisfaction in learning physics are not high,especially in the diagnosis,feedback,implementation,learning method guidance performance.By the analysis of survey data and practical teaching experience,there are three main reasons.Firstly,lack of technical means to support a large number of teaching work such as diagnosis and feedback.Secondly,the extensive teaching based on experience can not fulfill the teaching goal of physics in junior middle school.Thirdly,the test-oriented teaching psychology leads to the lack of guidance of learning methods,and the students' fatigue in practice results in low interest and satisfaction in physics learning.Therefore,on the basis of the above research,combined with the interviews between students and teachers,three feasible countermeasures are put forward.First,through technical means to improve the accuracy of Junior High School Physics Teaching Implementation.Then,through the Coordination of curriculum standards,experience to improve the accuracy of Junior High School Physics Teaching Function Implementation.Lastly,improving the accuracy of stimulating the vitality of physics teaching in junior middle school by changing the study habit.In addition,through the refinement and case design,we find that those countermeasures can improve the current situation of junior high school physics teaching,and can provide some reference for the related junior high school physics teaching.
