Study On The Connection Of Knowledge System Of Biology Teaching Materials In Junior And Senior High Schools Under The New Curriculum Standard

Person's education is a gradual process,according to the students' physical and mental development and ability of cognizance similarity,divide the students of physical and mental development,cognitive level consistent in the same grade,according to its development and the difference of the stages are divided into different grades,for example biological,in the different grade accept different teaching content,educational connection problem appears in adjacent learn stage.With the clear division of stage education,primary school,middle school and high school,the problem of education connection is increasingly deepened.High school biology curriculum is based on nine years of compulsory education,junior middle school textbook "compulsory education curriculum standard experiment textbook biology grade seven days" is in accordance with the "compulsory education biology curriculum standard(2011 edition)" writing,high school textbook "ordinary high school curriculum standard experiment textbook biological 1(compulsory)molecular and cellular is in accordance with the" ordinary high school biology curriculum standard(2017 edition)" writing,the new teaching material reform in biology knowledge system changes,the junior middle school and high school biology knowledge system cohesion problem.This paper studies the connection of biological knowledge system in junior and senior high schools.Firstly,it summarizes the development history of biology and the trend of education reform,and summarizes the important influence of the connection of knowledge system on the development of students' teaching and the overall development of people.In terms of the research status,the author has extensively studied the literature and found that there are few studies on the connection between the knowledge system of junior high school and senior high school biology textbooks at home and abroad,thus confirming the necessity of the research.Second,it distinguishes the meaning of "system" 、 "knowledge system" and "textbook knowledge system ",defines the meaning of "cohesion" and "knowledge system cohesion".Based on the three theories constructivism,system theory and lifelong education theory,it demonstrates the importance of knowledge system connection for discipline learningand lifelong development.On the basis of the curriculum standards,the author analyzes the new high school textbook "molecule and cell(compulsory 1)" and the junior high school textbook "biology grade 1" respectively from "point","line" and "surface" step by step to establish the knowledge system.Focus on middle and high school biology teaching materials in the study of the knowledge system connection.By comparing the two versions of the curriculum standards,the requirements of the new curriculum standards are clarified,and the students' learning situation,concept,content selection and other aspects to discuss the junior middle school and high school textbook knowledge system problems,and these problems in the process of teaching and textbook writing is ignored,this will directly lead to some teaching problems,for example,high school freshmen are not interested in biology,and some students can not connect with biology knowledge and other issues.Through the research on the knowledge system connection,the author hopes to better compile junior middle school textbooks from the perspective of cohesion education,update the textbook cohesion knowledge system in the direction of the new curriculum reform,strengthen the importance of knowledge cohesion in the teaching process,and provide teaching materials for front-line teachers.
