Practical Research On The Cultivation Of Structure And Function View In Junior Middle School Biology Teaching

Core literacy is essential in promoting the overall development of each student.The concept of life in the core literacy of the biology department has outstanding educational value.The concept is supported by the concept of facts,which is the sublimation of knowledge,and the promotion of biological knowledge to the concept of life is the key to cultivation.The concept of life is based on the concept of structure and function,and the cultivation of the concept of structure and function plays a foundation role in reaching the goal of the concept of life.Therefore,this study is based on the content of the fourth unit of junior middle school biology "People in the Biosphere",and aims to provide a reference for the actual teaching of life teaching based on the concept of structure and function.Firstly,through literature analysis,the research background and domestic and foreign research progress of structure and function view were analyzed and summarized.Combined with the biological content in junior middle school,the structure and function view was interpreted as: structure view,function view,structure and function view.Secondly,the questionnaire survey was used to investigate the current situation of teaching and fostering of the structure and function concept in the junior middle school stage.The main problems in the current teaching were analyzed and discovered:teachers did not know how to transform the professor of structure and function knowledge into the cultivation of the concept of life.In order to solve this problem,this study attempts to propose a spiral-rise structure and function concept fostering strategy.Cultivation strategies are divided into two aspects: "Curriculum Standards and Textbook Study" and "Cultivation Methods".Curriculum Standards and Textbook Study includes: research course standard to find teaching basis,sort out the content of structure and function in textbooks,summary of typical structure and function view knowledge system.The fostering methods are: model construction method,question string method,knowledge block diagram method,backward inference theory demonstration method,forward and backward analysis method.Then,use experimental research method to carry out experimental teaching to two parallel classes.The fostering strategy based on the structure and function concept willbe implemented in the experimental class,and the control class will conduct normal teaching.At the later stage of the experiment,the experimental effect will be analyzed through questionnaires,interview results and biological achievements to verify the feasibility of the fostering strategy.The experimental results show that the students in the experimental class have significantly improved their understanding,application and generalization of the structure and function concept.Compared with the control class,there are significant differences,and academic performance is also better.Explain that the implementation of fostering strategies can not only improve the students' level of structure and function,but also have a positive impact on biological achievements.Teaching practice has achieved good results.This proves that the training strategy is feasible in practical teaching.Finally,the conclusion of this study is drawn through analysis,and the shortcomings in the research process are summarized.
