Observation Research On High School Mathematics Classroom Teaching Based On Implementing The Core Competences Of Mathematics

With the promulgation and implementation of the "General High School Mathematics Curriculum Standards(2017 Edition)",the core literacy of mathematics has ignited the engine of mathematics education reform.Classroom teaching reform based on "core literacy of mathematics" has been carried out across the country,the key to the reform It lies in the implementation.The implementation of core literacy in mathematics classrooms is an effective yardstick for testing the results of reforms;carrying out research based on the observation of classroom teaching based on the implementation of core literacy in mathematics can understand the implementation of core literacy in mathematics classroom teaching and improve it according to the actual situation Teaching is of great significance to the development of students' core literacy and the improvement of teachers' mathematics core literacy teaching competence.This research mainly adopts literature analysis method and Delphi method(expert consultation method)to construct the classroom teaching observation table.Through the classroom observation method to understand the implementation of the teachers' mathematics core literacy in the mathematics classroom,the following two problems are mainly solved: one is construction Based on the implementation of the core literacy of mathematics,high school mathematics concept class,principle class,exercise class,probability and statistics class classroom teaching observation table;the second is to use the constructed observation table to observe the mathematics classroom teaching,explain the use and analysis method of the observation table.Based on the connotation of the core literacy of mathematics,the LICC paradigm and the actual classroom teaching situation,this research has undergone three rounds of expert consultation,revised and improved the observation table,and tested the effectiveness of the tools in the actual classroom,and finally constructed a high school based on the implementation of the core literacy of mathematics Mathematics classroom teaching observation table.The main conclusions of this research are as follows:(1)The four types of classroom teaching observation tables constructed are recognized by experts.The observation dimensions cover the classroom performance fields related to the core literacy of mathematics.The observation angle is concise and suitable for recording and processing.Observation points It sets high performance expectations for teachers' core literacy teaching,and different classroom teaching observation tools based on the implementation of mathematics core literacy are qualified;(2)After practical tests,the constructed classroom teaching observation table has good reliability and validity,It is effective to the predetermined observation target(the implementation of the core literacy of mathematics),and can provide effective information and data for it;(3)The observation table constructed can play a diagnostic function,and the observation report is used as the framework to diagnose the core literacy of mathematics in the classroom The implementation of the teaching,and based on the observation table and observation record,pointed out the direction for the improvement of classroom teaching,and provided specific suggestions and opinions,which can play the role of the observation table in the teaching practice of developing students' core literacy.This research refines the core literacy of mathematics into observable and evaluable teaching behaviors in the classroom,hoping to help teachers better grasp the gestation point and growth point of the core literacy of mathematics in classroom teaching,and promote the core literacy of mathematics in the high school math classroom Implementation in teaching.
