Research On Evaluation Of Biology Classroom Teaching Based On Life Concept

In 2014,the Ministry of Education issued the opinions on deepening the curriculum reform in an all-round way to carry out the basic task of moral cultivation,which put forward for the first time the need to develop students' core quality.In 2018,the standard of biology curriculum for senior middle schools(2017 edition)put forward the core quality of biology,and in 2020,the evaluation system of China's college entrance examination put forward the examination contents and requirements.How to carry out the cultivation of biology core quality in biology classroom teaching has become an urgent problem to be solved.In order to improve the quality of the cultivation of the concept of life in biology classroom teaching,this paper studies the evaluation of biology classroom teaching based on the concept of life.Firstly,the index frame of biology classroom teaching evaluation based on life concept is constructed through theoretical analysis,and the course examples are combined to make a preliminary revision.The index framework takes “teaching objective”,“teaching process”,“concept construction” and “classroom culture” as the first-level index,and sets up the corresponding second-level index under the first-level index.Secondly,based on the observation and analysis of five lessons,the evaluation criteria of each secondary index are synthesized,and the index framework and evaluation criteria are modified by using the Delphi method,forming the evaluation system of biology classroom teaching based on life concept.In the final evaluation system,the secondary indicators under “teaching goals” are “goal description,goal matching,goal achievement”,the secondary indicators under “teaching process” include “presentation and attention,interaction and guidance,autonomy and guidance,questions and answers,generation and response”,the secondary indicators under “concept construction” include“concept inspiration,concept guidance,concept deepening,concept integration,concept expansion”,and the secondary indicators under “classroom culture” include “cultural implication,teacher-student relationship”.On the basis of constructing the evaluation system of biology classroom teaching based on the life concept,the weight of each secondary index is obtained by the analytic hierarchy process,and the evaluation scale of biology teaching based on the life concept is formed.This scale is applied to the evaluation of 6 biology classroom teaching videos in senior high schools.According to the evaluation results,some teaching suggestions under the secondary index are put forward.Data analysis showed that the system had good raters reliability and construct validity.
