Research On Unit Subject Teaching Design Of Quadratic Function In Middle School Mathematics

The unit theme teaching design is to establish several teaching themes according to the level goals of the course implementation.The teacher follows the students' cognitive law and aims to improve the core literacy of the students,develops and reorganizes the teaching content of the unit,and carries out the teaching design of continuous class hours.This article mainly focuses on the unit theme teaching design of quadratic function to study how to better apply the unit theme teaching method in teaching practice.This article mainly uses the literature method and the lesson analysis method to study the unit theme teaching theory,and then interviews the frontline teachers through the form of interviews.The interview content mainly includes the teaching and learning of the quadratic function and the practice of the unit theme teaching method.he purpose of the interview is to determine the goal and direction of the unit theme teaching design.In the research of unit theme teaching design,this article mainly analyzes and studies the new curriculum reform,new curriculum standards,teaching materials,academic conditions,teaching objectives,teaching process,etc.,so that the teaching design can fully reflect the theory of unit theme teaching.After summarizing the general process of unit subject instructional design,this article first designs the entire unit of quadratic function instruction,and then sets continuous class hours and conducts instructional design for each class,mainly based on junior high school mathematics,Beijing Normal University The two sections of "Determining the Expression of Quadratic Function" in the textbook version and "The Nature of Quadratic Function" in the textbook of Beijing Normal University for high school mathematics are used as examples for the unit theme teaching design,and the teaching design of these two class hours is taught.Practice,and finally conduct interviews with students and teachers to understand the advantages and disadvantages of the unit theme teaching design in the practice process,and improve the teaching design in time through feedback.Finally,this article summarizes the unit theme instructional design theory and the practical feedback results of instructional design,and puts forward reasonable suggestions for the unit theme teaching of frontline teachers,so that the unit theme instructional design can be applied to teaching universally and efficiently.
