Precision Homework System Construction And Experimental Research Based On Correlation Analysis

Summarizes related research at home and abroad,found the personalized homework too much emphasis on students' academic performance differences,but neglected the students inner knowledge control level,and their mutual relevance,causing students after finish personalized homework problem sets,can't effectively build knowledge context,is not conducive to the student to the knowledge points systematically master,causes students to improve the knowledge level is limited.Therefore,how to effectively improve students' mastery of knowledge points and put forward effective implementation plans is one of the important topics of this study.Firstly,uses the literature research,this study analyzes the domestic and foreign about the principle of "personalized" homework,implementation method and implementation effect,the precise teaching,the characteristics of the diagnostic tests and correlation analysis,and their advantages in teaching,explores the possibility of combining them with personalized homework,at the same time try to by combining the theory of knowledge structure and cognitive target classification theory(revised edition),the study of the proposed problem,design a precise operation system model based on correlation analysis,and the system model of modules and the mechanism of realization in detail;Then,according to the functional requirements of the functional modules of the system model,a design scheme of the precision operating system based on association analysis was proposed,and the system was implemented.Secondly,this study used the precision operating system based on association analysis to carry out experimental research.This experiment research to a high school junior middle school three grade two classes next semester students as experimental object,by letting students use operating system based on correlation analysis of accurate testing practice,the students answer the questions on data by using the system,to carry on the association rules mining,and then corrects the association rules knowledge points,push the corresponding exercises for students,to strengthen the practice,students mastery of knowledge points,and then test to analyze the relevant data.The research results show that the exercises based on correlation analysis:(1)students can effectively reduce the number of wrong questions;(2)can effectively help students to build the relationship between knowledge points;(3)can effectively reduce the student's answer time,reduce the error rate;(4)homework teaching based on correlation analysis has certain effectiveness.To a certain extent,this study enriched the personalized operation teaching related theory,proposed based on correlation analysis in the study of exercises teaching proved effective,can be in the process of teaching,to help teachers know more about students mastery of knowledge,understand the students' internal psychological cognitive level of learned knowledge,can provide the new teaching model for personalized teaching,is expected to improve the lack of personalized homework now.
