Research On The Path And Practice Of In-depth Lesson Preparation In High School Mathematics From The Perspective Of PISA

High school is an important stage of talent training,and mathematics teachers are important instructors and collaborators in the implementation of the core quality of mathematics.The quality of lesson preparation of high school mathematics teachers is directly related to the professional development and teaching quality of teachers.PISA is a widely recognized means of testing literacy in the world,and its evaluation means are recognized by all countries.Studying PISA literacy and the core literacy of Chinese mathematics,and defining the meaning of in-depth lesson preparation.On this basis,on the one hand,the questionnaire was designed with the PISA test concept to investigate the in-depth lesson preparation of 141 high school mathematics teachers in X City,Fujian Province;on the other hand,the case study method was adopted to analyze the in-depth lesson preparation of a discipline leader in X City,Fujian Province,and put forward the path and method of in-depth lesson preparation under the PISA concept.The main conclusions of the study are as follows:1.Under the core literacy,the current situation of some high school mathematics teachers’ lesson preparation is not optimistic.There are some problems in lesson preparation,such as serious exam-oriented education thought,lack of research consciousness and innovation consciousness,and formalization of collective lesson preparation.Compared with skilled teachers and expert teachers,novice teachers pay too much attention to knowledge transmission.2.Academic leaders are in good condition of in-depth lesson preparation.Academic leaders can grasp the logic of the teaching material,be student-oriented,be good at creating problem situations,and promote the development of students’ thinking.He is good at applying information technology and attaches importance to students’ practical operation,which provides strong support for the proposal of deep lesson preparation path for high school mathematics teachers from the perspective of PISA.3.Path and method of deep lesson preparation in high school mathematics under the concept of PISA literacy.(1)Update the educational concept and pay attention to people-oriented;(2)in-depth lesson preparation,dig the teaching materials as the starting point,pay attention to the integrity of chapter knowledge;(3)create teaching situation,pay attention to the authenticity of situational materials and the Times;(4)Take thinking training as the foothold,be good at using thinking mapping,standardize the use of mathematical language,and pay attention to the innovation of teaching methods.Finally,take the concept class "The Expansion of Mathematics Department and the Concept of Complex Mathematics" as an example to explore the teaching practice of deep lesson preparation for high school mathematics under the concept of PISA.
