| The proposal of Chinese core literacy points out a new direction for Chinese teaching.Some researchers call Chinese core literacy "literacy goal",which is richer and more comprehensive than the original knowledge goal.Therefore,to achieve the literacy goal,Chinese teaching needs to play the comprehensive effect of Chinese curriculum in a complete language environment.However,the traditional single-article teaching aims at cultivating knowledgeable talents,which is characterized by detailed knowledge introduction and detailed digging and repeated skills practice,which is difficult to really implement the development of the core quality of Chinese.Therefore,the Chinese core quality calls for the transformation of Chinese classroom teaching.Under this background,large unit teaching comes into being.As a complete learning event,large unit teaching is more comprehensive and systematic than the traditional single-article teaching.It can effectively connect with the core quality of Chinese and is the "fulcrum" of the transformation of Chinese classroom.This paper takes the large unit teaching of high school Chinese based on subject core literacy as the research object,focuses on the current practice status of the large unit teaching of high school Chinese based on subject core literacy,proposes the optimization strategy of large unit teaching in view of the existing problems,and provides new ideas for the implementation of the core literacy of high school Chinese.The introduction of this study reviews the domestic and foreign research status of core literacy,Chinese core literacy,unit teaching and large unit teaching through literature reading.On this basis,the focus of this study is put forward,that is,to optimize the teaching strategy of large unit so as to better promote the improvement of Chinese core literacy.The first chapter firstly defines the concepts of "Chinese core literacy" and "large unit teaching",then discusses the connotation,characteristics,content elements and logic of the large unit teaching of high school Chinese based on the subject core literacy,and makes it clear that the large unit teaching of high school Chinese based on the subject core literacy is under the command of the big concept and big task.It has the characteristics of target comprehensiveness,content integration,activity systematism and evaluation diversity.In this part,it also expounds the significance of teaching high school Chinese large unit based on subject core accomplishment.In the second chapter,by means of student questionnaire survey and teacher interview,it is found that some teachers in the practice school have preliminarily practiced the teaching of large units based on the core quality of Chinese.However,currently,students do not participate enough in the learning process of large units,and teachers also have mistakes in the teaching implementation because of the unclear teaching strategy of large units.It is mainly manifested in four aspects: goal,content,process and evaluation.The third chapter aims at the problems existing in teachers’ implementation of large unit teaching of high school Chinese based on subject core literacy.Based on the analysis of the reasons,it starts with big concept,big task,big situation and multiple evaluation,respectively,and proposes optimization strategies for the objectives,content,process and evaluation of large unit teaching of high school Chinese based on subject core literacy. |
