Investigation And Practice Research On The Teaching Of Biology Modeling In Senior High Schools

In the course of the development of biology,the model method is an important method to study the biological phenomena and the laws of life.Scientists are also building a variety of models,in addition to DNA double helix models.The model is a simplification of things that can help students understand biological knowledge in biology teaching and use model methods to solve problems.In the new round of curriculum reform,The author put forward that "teaching process reworks practice",students can cultivate practical ability in the modeling process,and also help them master scientific research methods.In this study,we explore the specific problems in model construction teaching by means of questionnaires and interviews,put forward corresponding strategies and carry out practical research in order to provide reference for better model construction teaching.Based on cognitive learning theory,constructivist learning theory and meaningful learning theory,this paper makes a preliminary study on the present situation of construction of high school biological model by using literature method,questionnaire survey method,statistical analysis method,teaching material analysis method and experimental method the study.In the course of the study,the author integrates the teaching resources of the high school biology teaching materials systematically in order to provide more material sources for model construction teaching.And 500 teachers and students in different cities of Shandong province were investigated by questionnaires and interviews to understand the status of the teaching of biological model construction.The results of the survey show that the main problems are as follows:1.teachers is lack of systematic understanding of model and model construction teaching;2.students is lack of understanding of biological model;3.the teaching ability of model construction of different classes needs to be improved;4.new entry teachers' ability to use model needs to be strengthened;5.the time arrangement between the model construction and the teaching progress is lack of integration.On the basis of analyzing the problems,the paper puts forward strategies from two aspects of cognition and implementation.cognition : schools should pay enough attention;teachers should learn systematically and deeply;students should correctly understand modelconstruction teaching.In point of Implementation: puting forward corresponding strategies for the new teaching,review class,exercise class three different classes.Combined with the strategy putted forward,the model construction of biology teaching in senior high school is studied.The author designs teaching cases and divides two parallel classes taught into experimental class and control class.In the experimental class,the model construction teaching is carried out,while the control class adopts the previous teaching method.After the experiment,SPSS software is used to analyze the biology scores and learning interests of two classes.The results shows that the experimental group is higher than the control group.Finally,the author summarizes and analyzes the above research,drawing conclusions and reflecting on the deficiencies.
