Research On The Function Teaching Of Senior One Under The Guidance Of Core Literacy

Mathematics Curriculum Standards for Ordinary Senior High Schools(2017 Edition)clearly develop students' core literacy in mathematics,and cultivate students' correct values,essential characters and key abilities.Function is one of the main lines of middle school mathematics curriculum,and function is the foundation of the whole high school function learning,so the author thinks that it is necessary to study the function teaching of high school based on core literacy.This research is divided into three parts,the first part from the perspective of students learning and first-line teachers teaching test,interview and questionnaire,analyzing the status quo of the current high student function study and understanding of the teaching material,the method of the teacher in class,a glimmer of teachers' perceptions of the third chapter function teaching core literacy and mathematics into mathematics classroom means and difficult;The second part puts forward teaching strategies according to the results of the survey and interview of students and teachers,relevant theories and the requirements of the "Standard(2017Edition)" for functional teaching.The third part according to the proposed teaching strategies of "the concept of function","the monotony of function","power function" to carry out teaching design,as a teaching reference to improve the core quality of students.According to the requirements of core literacy and the research results,the author believes that under the guidance of core literacy,teachers can carry out function teaching in senior high school from these points.First,form the teaching mode of basic functions and master the method of function research.Second,follow the cognitive law of students,reasonably organize the teaching content;Third,do a good job in the function knowledge connection between junior and senior high schools,improve the ability of mathematical operation;Fourth,strengthen the study of simple abstract functions and cultivate the ability of mathematical abstraction;Fifth,attach importance to the teaching of function image and strengthen the ability of visual imagination.
