Research On The Current Situation Of PCK Transformation And Professional Development Strategy Of Physics Pre Service Teachers From The Perspective Of Deep Learning

With the development of the times,according to the requirements of teacher education,the state attaches great importance to the work of teacher education.Pre service teachers are the reserves of future teachers.It is very important to understand the knowledge level of pre service teachers to promote the professional development of pre service teachers.Based on the above background,this paper studies the current situation of knowledge transformation of physics pre service teachers from the perspective of deep learning.This paper is divided into five chapters.The main research questions include combing the components of PCK in combination with curriculum standards and describing the current situation of the transformation of physical pre service teachers' subject teaching knowledge in combination with in-depth learning design evaluation indicators,and putting forward corresponding professional development strategies.By combing the literature at home and abroad,this paper determines the meaning and elements of subject teaching knowledge.Combined with the views of scholars on the elements of subject teaching knowledge,the first level indicators are curriculum knowledge,teaching strategy knowledge,knowledge about students and evaluation knowledge.Combined with the four first level indicators and the understanding of the physical curriculum standards,the second and third level indicators are determined,so as to build the subject teaching knowledge index system of pre vocational physics teachers.By summarizing the meaning of deep learning and evaluation mode,this paper constructs the evaluation index of the current situation of the transformation of physics pre service teachers' subject teaching knowledge.Based on the index system of the subject teaching knowledge of pre vocational physics teachers,the questionnaire and the classroom observation scale were designed to understand the current situation of the subject teaching knowledge transformation of pre vocational physics teachers.Based on the results of questionnaire statistics and classroom observation,combined with the evaluation indicators,the paper concludes that the current situation of the transformation of physical pre Vocational Teachers' subject teaching knowledge is as follows: Generally speaking,the transformation of physical pre Vocational Teachers' subject teaching knowledge is in the shallow learning stage.The specific performance is to have some course knowledge,but not enough in teaching;the teaching strategy knowledge is relatively thin,and the teaching application efficiency is not high;to understand some of the knowledge about students,the actual teaching consideration is less;to clear some of the evaluation knowledge,the actual teaching reflection is less.Combined with the results of the investigation,this paper analyzes the causes of the current situation,and puts forward the following strategies to promote the professional development of pre service physics teachers: first,to improve learning initiative in knowledge construction;second,to increase practical experience in transfer application;third,to attach importance to the main position of students after learning;fourth,to carry out effective evaluation and reflection after practice observation.
