Research On The Application Of Mathematical Models In High School Biology Teaching

In China's biology curriculum standards for ordinary high schools(2017 edition),it is pointed out that the core accomplishment of biology includes the concept of life,scientific thinking,scientific inquiry and social responsibility,and it is emphasized that students should cultivate the concept of life and explore and explain the phenomena and laws of life through model construction.Mathematical models can help students learn knowledge systematically and integrally,acquire learning methods and skills,and help students use some mathematical tools to deal with complex exercises and improve their problem-solving ability.However,in the current biology teaching in high schools,the construction of mathematical models is not enough.In addition,most mathematical models in biology teaching are classified according to mathematical tools,which cannot fully reflect and grasp the psychological cognitive characteristics and biological characteristics of high school students.Therefore,this research will be through teaching practice,the mathematical model and the reference based on the classification of mathematical model in mathematics teaching,mathematical model of classification for preliminary exploration,design the corresponding teaching strategies,make students participate in the construction of mathematical model for the process,the mathematical model and explore the teaching to the students' ability to solve problems and cooperation ability.Through the interviews and investigations on the current situation of mathematical model teaching among some high school biology teachers and students,the results show that some teachers have weak awareness of mathematical model and single teaching methods.In daily study,students seldom participate in the activities of mathematical model construction and the application of the model is not optimistic.But generally speaking,high school teachers and students have a high degree of recognition of mathematical model,supporting the development of mathematical model teaching content.According to the current situation analysis and teaching practice,this study refer to the classification of mathematics teaching in the mathematical model,the mathematical model will be in high school biology according to the characteristics of object will be divided into:"class" mathematical model,the mathematical model of the method of "class","class" scene mathematical model,and in the mathematical model is constructed on the basis of the general steps of put forward the corresponding teaching strategies,after screening the teaching content is applied to teaching practice.This study selected learning situation,the high school biology problem solving ability,cooperation ability no significant differences between the two classes of students as the research object,the experimental group according to the classification of the mathematical model and build the corresponding teaching strategies,the control in conventional teaching,practice after the end of the two groups of problem solving ability,cooperation ability,teaching evaluation on the degree of knowledge.Through the teaching practice of one semester,and the use of relevant scales and biological questions to assess the two classes,the use of SPSS software statistical analysis of experimental data,comprehensive evaluation of the practical effect.Results show that:(1)compared with control group,experimental group the biological problem solving ability of students has increased significantly(P=0.043<0.05),including problem solving attitude in biology,biology,problem solving strategy,biology information processing the three dimensional contrast appeared significant difference(P<0.05),but in the structured knowledge of biology and biological information recognition on the two dimensions of both difference is not obvious(P>0.05).(2)in terms of cooperation ability,there was no significant difference between the experimental group and the control group in the post-test on the whole.There were significant differences in the two dimensions of sense of identity and sense of honor,expression and communication,but no significant differences in the two dimensions of management and negotiation,reflection and evaluation.(3)there was no significant difference between the two classes in terms of their biology academic performance,but there was a significant difference in the results related to the mathematical model.Therefore,the conclusion is drawn that mathematical model teaching can help students master mathematical statistical analysis knowledge,improve students' problem analysis and solving ability,and better play the role of group cooperation.This study preliminarily explores the classification of mathematical models and corresponding teaching strategies in high school biology,which can not only improve students' problem-solving ability and cooperation ability,but also promote the cultivation of students' core accomplishment in biology,which is conducive to the improvement of teachers' comprehensive quality and professional accomplishment.In addition,the research results of this paper can enrich the research system of mathematical model teaching and provide reference for first-line biology teachers to carry out mathematical model teaching.
