| With the vigorous promotion of the new curriculum reform in senior high schools in China,the implementation of the Biology Curriculum Standards for Senior High Schools(2017 edition),the new concept of senior high school biology education is to develop students’ core literacy,focusing on the concept of content,requiring students to use models and models based on biological facts,understand and master the concept of biology.Therefore,the research on the construction and application of conceptual model in senior high school biology teaching aims at improving teachers’ modeling literacy and teaching ability,cultivating students’ scientific thinking and modeling ability,and providing effective reference for the development of first-line biology conceptual model teaching.This research mainly includes the following contents:Firstly,by collecting and sorting out the relevant information,we study the current situation of the teaching of model and concept model construction at home and abroad,and find that there is a lack of systematic research on biological concept model in China.By means of teacher interviews and student questionnaires,this paper investigates the current situation of biology conceptual model teaching in senior high schools in Shenyang,and finds out that some senior high schools are limited in carrying out biology conceptual model teaching.Some teachers lack the knowledge and application of biology conceptual model teaching.In classroom teaching,students seldom construct biology conceptual model independently,and students are limited in biology concepts teaching.There are some deficiencies in the cognition and construction of the model.Secondly,based on the results of the survey and analysis,four countermeasures are put forward:(1)the school regularly carries out a series of activities of biological concept teaching;(2)the teachers study the ideas and methods of strengthening the teaching of biological concept model;(3)the teachers guide students to construct and apply biological concept model scientifically;(4)the students learn to master the construction methods of biological concept model and apply it to practice.The teaching of biological conceptual model includes six steps and methods:(1)creating situations and introducing concepts;(2)defining connotations and forming concepts;(3)analyzing relationships and processing concepts;(4)building models andstoring concepts;(5)modifying models and improving concepts;(6)applying models to consolidate concepts.On this basis,the case design of biology conceptual model teaching is formed,and applied to the actual teaching for testing and effect evaluation.Practice shows that the application of biological conceptual model in teaching can guide students to actively model,help students understand biological concepts,and promote the teaching of biological concepts.Finally,summarize.Because of the limitation of personal ability and research ideas,the scope of this study is not comprehensive enough,and the degree of innovation and development is not deep enough and extensive enough.In the future,the author will continue to innovate in teaching and explore the application prospects of expanding conceptual models. |
