Research On The Practice Of "Scaffolding Instruction" In Senior High School Biology Teaching

The release of " the 2017 standard high school biology curriculum" means that the new curriculum reform has reached a new level.The state puts forward new requirements for the standard of talent cultivation.It is necessary to make the cultivated people conform to the development of modern society.There are many teaching modes under the guidance of constructivism learning theory."Scaffolding instruction model" as one of the outstanding,has been studied and used by many educators at home and abroad.In particular the constructivism learning theory,learning is a process of active,knowledge is the result of the active construction,students are the main body of learning,the teacher is the leader and promoters and managers in the study,these education concepts are in line with our country’s requirements for talent cultivation.Therefore,the "supporting teaching mode" is in line with the students’ orientation in the reform of the new curriculum,respecting the students’ subjectivity and diversity,and focusing on the teaching concept of learning and advocating cooperative learning.It is necessary to carry out the practice exploration of "scaffolding teaching mode" in high school biology curriculum teaching.This study consists of four parts:The first part elaborates the research background,research purpose,content and method of this research.The second part elaborates the theoretical basis of "scaffolding teaching mode",including the theory of social constructivism and the "recent development area".The third part analyzes and defines the concept of "scaffolding mode","teaching mode" and "scaffolding teaching mode",then,I also contacted the biology content of high school to analyze the scaffolding construction principles and teaching implementation steps of "scaffolding teaching mode";This paper summarizes the teaching design process and makes "scaffolding teaching mode" more operational in high school biology teaching.The fourth part,first of all,the "scaffolding teaching mode" in high school biology compulsory second "heredity and evolution" in practice,How to apply the "scaffolding teaching mode" to the teaching design and teaching implementation with the concrete instance-"sex-linked inheritance" teaching design.Then,in the first grade,two parallel classes were selected to do education experiment.The experimental class was taught under the guidance of "support teaching mode".The control class was taught in the conventional teaching mode.After a period of experiment,the final test scores of the two classes were taken as the test scores,and the scores of the two classes were analyzed.
