Research On The Teaching Of Basic Elementary Functions Based On Mathematical Modeling Core Literacy Training

China's economic development is in a critical period of transformation.In order to realize the strategic demand of developing a strong country through science and education,the classroom teaching needs to be reformed and improved with The Times.High school is a critical period for the formation of students' subject literacy,which can establish a good relationship between mathematical knowledge and the real world.Classroom teaching is an important way to cultivate students' discipline accomplishment.The curriculum standard issued in 2017 clearly stipulates the six core qualities of mathematics.In the teaching process,efforts should be made to cultivate students' quality and build scientific mathematical values.The study of mathematics can teach students to look at the phenomena in the real world with a mathematical perspective.Function model is an important tool to explore the objective phenomena in the real world.It is the key of applied mathematics to accurately abstract problems from the real world and apply mathematical knowledge to solve them.The teaching of basic elementary functions is an important process to train students to solve problems in applied mathematics.Students acquire the knowledge of basic elementary function relies on classroom learning,but the current high school mathematics classroom teaching by teachers on the way,even the teacher agreed that students independent thinking cooperation inquiry can exercise the students' ability of mathematical modeling,the process ofrecognition of mathematical modeling core literacy is of great significance to study mathematics applied mathematics,but most of the teachers in classroom teaching and emphasized practice problem solving,professor with the Angle of entrance examination knowledge,not literacy in teaching.Based on the analysis of the domestic and foreign literatures on mathematical modeling and basic elementary function teaching,this paper analyzes the common problems of students in basic elementary function classroom learning and mathematical modeling literacy through the investigation of the learning status of students in basic elementary function teaching and the interviews with teachers.From the perspective of mathematical modeling core accomplishment,the teaching is divided into four stages: perceptual knowledge,differentiation of essential attributes,generalization of formation model,and reinforcement and application.Verify the effectiveness of the experiment randomly selected two classes,set up the control experiment,two classes of experiment test before the experiment,ruled out two class foundation level differences cause interference with the result of the experiment,adopt the method of experimental classes and that in comparative classes,and to test two classes after the test,the experimental conclusion,finally the conclusion summarizes and puts forward the outlook for an experiment.
