Design And Application Of Precision Teaching Model For Mathematics Lectures In Senior Middle Schools Based On Online Marking System

As an important type of mathematics teaching,lectures teaching has a variety of functions,such as motivating,constructing a knowledge map,improving problem-solving skills,and cultivating mathematical ideas.However,in actual teaching,teachers did not give full play to the teaching function of lectures.In recent years,some middle schools have successively purchased online scoring systems,which are used in the normalized teaching of middle schools.They integrate information technology with commentary courses and use the multiple functions of the online scoring system to assist teachers in teaching.Therefore,it is very important to explore a set of effective teaching models that apply the online assessment system to mathematics lectures in senior high schools,so that the lectures are more accurate and the teaching efficiency is improved.In this research,firstly,through literature research and questionnaire surveys,we learned the current teaching status of high school mathematics papers and lectures and analyzed the reasons for these current conditions.Secondly,under the guidance of related theories,an accurate teaching model of high school mathematics lectures based on the online scoring system was constructed,with a view to promoting the improvement of students’ knowledge and skills,and the teaching efficiency of high school mathematics lectures.This model is mainly designed from the three links before,during and after class.The core design content of the model is mainly: first,accurate teaching goals before class,accurate diagnosis of problems,second,precise intervention in teaching during the class,and group cooperation The teaching activities such as exploration,difference guidance,etc.,the third is the accurate remedy and expansion after class,and has carried out empirical research in the second grade mathematics lectures in the F high school of F city.After three months of comparative teaching,the knowledge and skills of the students in the experimental class have improved to a certain extent,and the teamwork ability and problem solving ability of the students have also been developed.Research experiments show that the teaching mode of the lecture can improve the teaching efficiency of the lecture to a certain extent.
