Practical Research On The Connection Of Biology Teaching In Junior And Senior High Schools Based On Core Literacy

The 21 st century is the era of globalization and informatization of the knowledge economy,which puts forward higher requirements for the cultivation of talents.Countries around the world have carried out research on core literacy.From the initial research on core literacy to the full implementation of the new curriculum reform,core literacy has been paid more and more attention in China.The purpose of the biology curriculum after the new curriculum reform is core literacy,which is reflected in the specific teaching,which is to implement the core literacy in all aspects of teaching.The curriculum should be an organic coherent whole.But in fact,the differences in teachers' teaching methods,students' learning methods,and teaching contents have caused the biology teaching in junior and senior high schools to be split into two parts.As an indispensable teaching link,teaching connection has been neglected by many teachers for a long time.As an indispensable teaching link,teaching connection has been neglected by many teachers for a long time,which can ensure a smooth transition between junior and senior high schools biology courses.Therefore,according to the current situation of teaching connection,this paper takes core literacy as the starting point to study the connection of biology teaching in junior and senior high schools.This paper begins with a detailed elaboration of the research content and related research status,and then gives the definition of some related concepts and analyzes the relevant theoretical research.In order to understand the current situation of teaching connection implementation and core literacy training,this research also conducted a questionnaire survey of teachers and students and interviews with high school teachers.After collating and analyzing the obtained questionnaire data and interview results,the current situation is obtained,problems are found and suggestions are made.The arrangement of connection points can facilitate the implementation of teaching connection.Curriculum standards and teaching materials serve as an important basis for teachers to carry out teaching,so they are the focus of this research to find connection points.The connection analysis of the curriculum standards compares the correlation and difference of the curriculum standards in junior and senior high schools and points out their guiding significance in teaching connection.The connection analysis of the textbook is to sort out the knowledge points of each chapter in the high school textbook,and then sort out the related connection points in the junior high school textbook,and analyze the core literacy focus of each connection point.In order to test the effectiveness and necessity of teaching connection,an experimental study of teaching connection is also carried out.The teaching experiment was carried out by analyzing the pre-and post-test data of the experimental class and the control class after the teaching connection in the experimental class.It is found that teaching connection has a certain role in promoting students' mastery of basic knowledge and the development of core literacy.Later,taking "The Principles of Photosynthesis" as an example,a specific teaching connection case was designed,including teaching connection analysis,suggestions and specific teaching design.Finally,this paper summarizes the research content of the full text,and draws the following conclusions and suggestion: the connection between middle and high school teaching has certain necessity and value;middle and high school teachers should communicate as much as possible in teaching;pay attention to the teaching connection between experiments and inquiry activities;the junior high school pays attention to extension and expansion,lays a foundation and stimulates interest at the same time,understands the learning situation in the senior high school,and carefully designs connecting teaching activities;teachers should make reasonable arrangements for teaching content and improve teaching design according to the connection points that have been sorted out.At the same time,the deficiencies in this study are also analyzed.The purpose of this paper is to provide a reference for high school biology teachers to carry out teaching connection.
