The Construction And Practice Of The Evaluation System Of High School Biology Confirmatory Experiment Teaching

The "General High School Biology Curriculum Standards(2017 Edition)" published by the Ministry of Education in 2018 emphasized that the evaluation should be based on the development of students,paying attention to the core literacy of the discipline and promoting the teaching of teachers and the learning of students.So,the teaching of biological experiments should be strengthened and the opportunities for students should be increased to do more experiments tofocus on cultivating the core qualities of students..According to the purpose of the experiment,high school biology experiments could be divided into confirmatory experiments and exploratory experiments.Confirmatory experiments played an important basic role in training students' experimental operation skills,cultivating scientific attitudes,and improving experimental thinking ability.Nowadays,although many scholars and teachers studied on the evaluation of experimental teaching,most of them just put together confirmatory experiments and exploratory experiments,ignoring the characteristics of confirmatory experimental teaching.And their teaching evaluation had not been adequate value..Based on the core literacy of the biology subject in the curriculum standards and the characteristics of the confirmatory experiment,and the perspective of teachers and students,a scientific and feasible evaluation system wasattempted to construct in this study.And then the high school biology confirmatory experimental teaching was conducted accordingly.Evaluation after teaching aimed at making up for the lack of verification experimental teaching evaluation research,and promoting the development of teachers and students through evaluation.In this study,the literature research method,survey research method and other literature data methods,survey research method,Delphi method,factor analysis method and other research methods were used.The combination of qualitative and quantitative methods was used to construct a high school biological verification experimental teaching evaluation system,forming an evaluation scale.It was expected that the evaluation scale would be benefit for evaluating confirmatory experimental teaching,to understand the performance of teachers and students in confirmatory experimental teaching,and then to put forward practical suggestions for the teaching.There included mainly s four parts in this paper.The first part was to discuss the current status of the verification experiment teaching evaluation at home and abroad,and to define the relevant concepts of the evaluation system.The second part was to comprehensively analyze the school experimental teaching evaluation status,determine the evaluation dimension,Evaluation indicators and evaluation standards construct a verification experiment teaching evaluation system;the third part was to use the constructed evaluation system in theverification experiment teaching practice.Corresponding suggestions on the implementation of verification experiment teaching was put forwardin the last part.The results of the comprehensive evaluation study were summarized as follows: first,the verification experimental teaching evaluation system constructed by this study was reasonable and scientific;second,the evaluation system constructed by this study had the characteristics of holistic,targeted,comprehensive and systematic,which couldable to be used to evaluate the of confirmatory experimental instruction.According to the evaluation results,combined with teaching reflection,the following suggestions were proposed: 1.Form a group to help each other;2.Encourage inspire thinking and interact with each other;3.Refine the guidelines comprehensively;4.Supplement and expand to enlighten thinking;5.Multi-evaluation focus on development.
