Research On The Mathematical Model Of The College Entrance Examination And Teaching Practice

In addition to the selection function,the high examination volume has a clear guiding function for reviewing preparation and high school teaching in the future.This research uses the literature research method to understand the research status of mathematical model teaching in biological mathematics model teaching and the biological test paper of college entrance examination.Using the comparative research method,the mathematical model test questions of the national college entrance examination in 2014-2018 are taken as the research object,and the statistics are combed.The type change of mathematical model test questions;the number,score and ratio change of mathematical model test questions;the title number,score and ratio of six national mathematics model test questions of National Volume I,National Volume II,National Volume III and six types of mathematical model test questions Knowledge point distribution.Summarize the overall changes of the test questions:(1)In terms of the type of mathematical model,the national volume survey is the most comprehensive,the national volume is once,and the national volume is the least;(2)the curve model and the tabular model are the most studied mathematical models;(3)The basic laws of photosynthesis and inheritance are the most frequently occurring knowledge points.At the same time,the characteristics of the six types of mathematical model test questions,the solution to the problem solving method are specifically elaborated and the classic mathematical model college entrance examination questions are illustrated.Using the educational experiment method,guided by the educational modeling theory and the constructivist learning theory,based on the test sites and model construction methods of the biological mathematics model test questions of the college entrance examination,the teaching design and guidance of the mathematical model knowledge points of the compulsory secondary school textbook must be designed.In the case,the teaching practice of the two classes with similar levels in the next semester,the students of the experimental group carried out the model construction teaching,and used theguide designed by the author to actively construct the mathematical model in the classroom.The students in the control group carried out regular teaching and adopted a unified school guide to passively construct mathematical models in the classroom.The SPSS17.0 software was used to analyze the corresponding chapters and final grades of the two classes.After a period of time,the difference between the two classes was significant,indicating that the mathematical model construction method can effectively improve the students’ academic performance.
