Study On The Present Situation And Optimization Suggestion Of Physics Teachers' DTPCK In Junior Middle School

A new round of curriculum reform proposes to develop students' core qualities,and how to cultivate students' core qualities through educational practice has been widely concerned by education researchers and teachers.In-depth Teaching,which focuses on students' long-term and comprehensive development,is regarded as an effective way to develop students' core literacy.DTPCK(Deep Teaching Pedagogical Content Knowledge),an important part of teachers' Knowledge,is also the key to their successful in-depth Teaching.The theoretical discussion and current situation investigation of junior middle school physics teachers DTPCK can expand junior middle school physics teachers' teaching knowledge research horizon,contribute to enrich the in-depth physics teaching research,provide empirical research reference for evaluating teachers' current situation of physics DTPCK,and promote the professional development of junior middle school physics teachers.Based on in-depth teaching and discipline of physics teachers teaching knowledge of existing research,this paper discusses the connotation and value of DTPCK,type,stage,and influencing factors,and mainly discusses the content of the DTPCK structure,containing physical depth knowledge teaching ideas,the depth of the physical teaching object depth of knowledge,physical teaching content knowledge and depth of physical teaching strategy knowledge and depth of physics teaching evaluation.Combined with the content structure of DTPCK,the measurement dimension of DTPCK was established,and the questionnaire was designed and perfected to carry out the current situation measurement of DTPCK for junior middle school physics teachers.Through the questionnaire survey found that at present our country junior middle school physics teachers DTPCK structure imbalance,the understanding of the depth of the teaching to improve perfect,some teachers lack dig deep knowledge of physics teaching content,teachers' lack of knowledge about students deep learning approach,the junior middle school physics teachers lack of knowledge of higher-order thinking cultivation strategies and teachers' teaching reflection is beneficial to the development of its DTPCK.In view of the shortcomings found in the survey,the following four optimization Suggestions are put forward: changing the traditional educational concept and enhancing the awareness of in-depth teaching;Teachers actively carry out deep learning and form an in-depth and integrated teaching content system.Analyze the learning process and accumulate the knowledge of deep learning;Teachers reflect on their own teaching behavior in many ways to enrich the strategic knowledge about the cultivation of students' high-level thinking.
