Research On Junior High School Physics Teaching Strategy Based On The Development Of Scientific Thinking

The "Compulsory Education Physics Curriculum Standard(2011 Edition)" requires students to develop good thinking habits,be able to think independently,dare to question,respect facts,and have the courage to innovate.In actual teaching,due to the selection of the middle school entrance examination,the teaching of junior high school teachers is mainly aimed at the content of the middle school entrance examination,while ignoring the development of the students.Therefore,in the three-year teaching of complete middle school,there are frequent students' maladjustment to physics learning when they enter high school.The author communicated with colleagues and found that the main reason that restricts students' physics learning is the lack of thinking ability after students enter high school.In 2017,the proposal of high school physics core literacy has more clearly defined the requirements for students to cultivate scientific thinking.Based on this,how to cultivate students' scientific thinking ability in junior high school has become one of the core problems in junior high school physics teaching.Through combing and summarizing the research results of predecessors.According to the requirements of scientific thinking in physics core literacy and advanced learning theory,constructivism theory and humanism theory,a questionnaire survey was conducted among junior high school physics teachers in Jingning County,Gansu Province.The problems existing in the teaching of physics scientific thinking in junior middle school summarized,and the reasons have been analyzed in detail.Based on the practical teaching experience,combined with the characteristics of scientific thinking and teachers' survey results,the preliminary strategies for the development of scientific thinking in junior middle school physics teaching have been put forward in this study.Additionally,according to the preliminary strategy formulated,combined with the requirements of junior high school physics teaching at this stage,teaching cases were designed and put into practice for different types of junior high school physics.In the course of practice,experienced physics teachers at the front-line were invited to conduct classroom observations.Combined with the classroom observation scale,the effect of the initial strategy was evaluated.According to the application effect of the preliminary teaching strategy and the corresponding teaching theory,the preliminary teaching strategy was further improved,and the junior high school physics teaching strategy based on the development of scientific thinking was summarized: situation-problem strategy,inquiry-construction strategy,reasoning-argument strategy,interaction-communication strategy and observation-evaluation strategy.Explained the content of the teaching strategy in detail,put forward suggestions on the use of corresponding strategies,and finally carried out reflection and prospect.In this paper,based on the development of scientific thinking of junior high school physics teaching strategy,to improve the quality of junior high school physics teaching has a certain reference significance.
