Video Analysis Of Mathematics Teaching Based On Deep Teaching Practice Framework

With the development of science and technology and more and more "pseudo-inquiry" and "pseudo-cooperation" appear in the classroom,education will inevitably undergo further deepening reform.Deep learning and deep teaching are proposed under this background.However,mast researchers' research on deep teaching only stays at the theoretical level.Some researchers do not have a deep understanding of deep teaching or even have a wrong understanding.In addition,although the practical part of in-depth teaching is mentioned,it does not form a unified understanding,and the suggestions about practice are often not practical.In view of this,the purpose of this research is mainly to define the concepts related to in-depth teaching,and to think critically about the problems related to in-depth teaching.On this basis,a set of practical operating system is established.The main questions of this research are:(1)What is the current status of in-depth teaching?(2)What is in-depth teaching?How to define its connotation?What are the characteristics?(3)Why conduct in-depth teaching?(4)What does in-depth teaching teach?(5)Who is the target of in-depth teaching?Do all students need to teach in depth?(6)When is it suitable for in-depth teaching?Does each class require in-depth teaching?(7)How to conduct in-depth teaching?How to implement in-depth teaching?In view of the above purpose and problems,this study deeply analyzes and discriminates the connotation of depth and depth teaching,and makes an in-depth analysis of the five original problems of depth teaching.What does in-depth teaching teach?When is it suitable for in-depth teaching?Who is the target of in-depth teaching?How to conduct in-depth teaching?And from six aspects,how to conduct in-depth teaching has been analyzed in more depth,based on which the in-depth teaching practice framework,in-depth teaching target framework and in-depth teaching video analysis step framework have been established.Among them,the in-depth teaching practice framework contains a total of 4 dimensions,11 indicators,44 observation points.The four dimensions of the in-depth teaching practice framework are subject knowledge,teacher teaching,student learning,and classroom environment.The subject knowledge dimension includes three indicators:"structure","essence",and "application";the teacher teaching dimension includes"process","Guidance" and "wit" are three indicators;the student learning dimension includes "interaction","focus" and "reflection";the classroom environment dimension includes "question" and "emotion" 2 indicators.This provides a framework for teachers to conduct in-depth teaching and in-depth teaching evaluation,but also provides a reference system for teachers to select observation points and develop teaching video analysis tools.In addition,based on the in-depth teaching practice framework,this study designed a series of in-depth teaching video analysis tools suitable for the in-depth teaching video analysis step framework,including:in-depth teaching behavior guide,in-depth teaching video analysis training table,in-depth teaching Video analysis question list,in-depth teaching video analysis dialogue guide and in-depth teaching video analysis evaluation scale,etc.Among them,the in-depth teaching behavior guide and the in-depth teaching video analysis training table are suitable for the preparation stage of video analysis.The in-depth teaching video analysis question list is mainly used for the analysis of various dimensions of in-depth teaching in the analysis process,and the in-depth teaching video analysis evaluation scale is mainly used for the preliminary evaluation of the teaching video.In-depth teaching video analysis dialogue guide is mainly used for teaching reflection of lecturers and video analysts after video analysis.In addition,based on the in-depth teaching practice framework and step framework,this study analyzes one online teaching video in elementary school,junior high school and high school with the aid of in-depth teaching video analysis tools to demonstrate the entire process of in-depth teaching video analysis In order to provide teachers with a practical paradigm for operation.
