Research On Explore The Students’ Understanding Level And Teaching Practice Of High School Biology Mathematical Model

This study adopts the method of questionnaire investigation to 244 students,the questionnaire is prepared according to the research on the model of attention dimension,the Mathematical Model of knowledge integration for finishing about six dimensions:Mathematical Model of the connotation,Mathematical Model Presentation,Mathematical Model of the Function,the Multiple of Mathematical Model,Construction the Mathematical Model and Revise Mathematical Model.The dimensions of the model knowledge are divided into several levels for different researchers,according to these leves,a questionnaire was designed in this study,about14 single choice question.The Cronbach’s Alph coefficient of the whole questionnaire was 0.873.Through the questionnaire survey,the students’ Biological Mathematical Model Knowledge is tested,The results show that(1)the level of understanding the dimension of Mathematical Model of the connotation is between 1and 2 level.There was a significant difference between the A group and the B group.(2)the level of understanding the dimension of Mathematical Model Presentation is between 1 and 2 level.And there is no significant difference between the A group and the B group.(3)the level of understanding the dimension of Mathematical Model of the Function is between 2 and 3 level.And the differences between the A and B groups are significant.(4)the level of understanding the dimension of the Multiple of Mathematical Model is between 1 and 2 level.And there is no significant difference between the A group and the B group.(5)the level of understanding the dimension of Construction the Mathematical Model is at the first level.And the differences between the A and B groups are significant.(6)the level of understanding the dimension of the Revise Mathematical Model is between 1 and 2level.And there is no significant difference between the A group and the B group.Explore the students’ understanding level,the results shows that the level of construction the Mathematical Model is lower,and the differences between the A andB groups are significant.Combine the educational modeling theory whith the resullts,design the teaching activity of mathematical modeling,and use it to the teaching practice of the senior two students.The experimental results show that the scores of the experimental group is significantly higher than the control group,indicate that teaching based on students’ understanding level of mathematical models can improve students’ academic performance.
