Construction Of Observation Index Of Teacher-Student Interaction Under Ecological Physics Class In Senior High School

In the report of the 19 th National Congress of the Communist Party of China,Xi Jinping,the general secretary repeatedly stressed the need to accelerate Chinese entry into a new era of ecological civilization.Ecological civilization is not only reflected in the humanity environment,but also in the field of education.Creating a harmonious,equal and sustainable ecological class is the key to developing students' core qualities.In class,teacher-student interaction is a “bridge” that closely links teachers,students,and teaching activities,it is also an important way to promote the continuous progress and development of students.This thesis takes the interaction between teachers and students as the research object,and analyzes it ecologically and construct the observation index.Reviewed a large number of domestic and foreign literature,and summarized them.Through the analysis of the existing research results,the first-level index of the "Observation Index of Teacher-Student Interaction Under Ecological physics Class in Senior High School" is determined as:understanding before teacher-student interaction;interactive process;interactive evaluation.Secondary index: understanding of teaching materials,understanding of students,understanding of teacher-student interaction;frequency and duration of interaction,type of teacher-student interaction,ways of teacher-student interaction,factors influencing teacher-student interaction;behavioral evaluation before teacher-student interaction,behavioral evaluation in the process of teacher-student interaction.On this basis,combing with the video of the11 th National Middle School Physics Young Teachers Teaching Contest(High School Group),consulting experts in education and in-service teacher,the secondary index are more detailed,determined the three-level indicator.I finally constructed the "Observation Index of Teacher-Student Interaction Under Ecological physics Class in Senior High School".Applying "Observation Index of Teacher-Student Interaction Under Ecological physics Class in Senior High School",observing and analyzing the teaching of the three courses of “Free-Fall Motion”,“Friction”,“Gravitational Potential Energy”,Ifound three aspects of "non-ecological" phenomenon:(1)Ignoring the subjective status of students,the class is still centered on teachers.(2)Teachers did not put the development needs of students in the first place when interacting with students.(3)the fixed and single teacher-student interaction mode,lack of flexibility.
