The Application Of Model Construction Method In Biology Teaching In High School

With the rapid development of biological science and technology,the training objectives of students in biological classroom teaching have also changed with the times.One of the important goals of the new curriculum reform is to change the traditional teaching mode of "subject-centered" and "knowledge-centered".In 2017,the "General High School Biology Curriculum Standards" was promulgated,emphasizing the cultivation of students' core quality in biology.Core quality of Biology can comprehensively reflect students' scientific methods,scientific attitudes,scientific values and the ability to apply biological knowledge.In the curriculum standard,the model construction is considered to be an important means to cultivate students' biological science literacy,and clearly points out the importance of modeling ability in high school biological learning.However,the current research on the model construction in high school biology teaching mainly focuses on the theoretical knowledge and several classic teaching cases.In practice,how to construct different types of models is lack of targeted method guidance.This research aims to cultivate students 'modeling ability and improve teachers' model construction teaching literacy,so as to provide effective references for the practical application of model construction in high school biology teaching.In this study,the research objects are teachers and students in Tongze Middle School in Haicheng City,using literature research methods,interview methods and case analysis methods.The research content is the application of model construction in high school biology teaching.Firstly,the related concepts and theoretical basis of the model and model construction method are clarified,and the research status of the model construction method at home and abroad is clarified;Secondly,interviewed all biology teachers and some students in Tongze Middle School to understand the application of model construction in high school biology teaching;Thirdly,the basic principles and general methods of model construction are clarified,and put forward specific construction strategies of different types of biological models;In addition,based on the collation and analysis of the model resources in the module of "Molecule and Cell",the teaching design is made;Finally,according to the analysis of the interview results after the practice,the research conclusions are drawn,and some suggestions are put forward for the application of the model construction in senior high school biology teaching.According to the research content,the following conclusions can be drawn:1.The model construction method is not widely used in senior high school biology teaching,which is closely related to teachers,students,schools and other factors.2.It is of great significance to clarify the basic principles and general methods of model construction in teaching.3.The application of the model construction in senior high school biology teaching plays an important and positive role in the study of students' biology knowledge and the improvement of teachers' comprehensive quality.
