| Since the release of the core literacy of Chinese students’ development,every link of education has been undergoing changes,and the reform of homework is also being carried out accordingly.How to improve the efficiency of homework and assign homework more scientifically and reasonably is a direction of homework reform.When the author taught,I found that the current homework form of the school is relatively monotonous,and it can not take care of the individual differences of students’ mathematics learning.There is a phenomenon of "forgetting while learning",and the current form of homework is only for the content that students have learned recently.The homework lacks the knowledge review across chapters and modules,and the effect is not obvious on improving students’ comprehensive ability.Based on the above content,after consulting the relevant literature,the author innovated the stratified homework,added the review and consolidation function in its stratified characteristics,and created the "stratified group homework".Stratified group homework is a kind of additional homework,its "stratified" characteristics is: homework is divided into progressive group and excellence group.Students with different abilities and cognitive levels can voluntarily choose to enter the group suitable for them.Its "review" characteristics are as follows: the two levels of homework content are the knowledge that the students have learned,and it can connect what students have learned with what they are learning.This study mainly adopts quasi-experiment method,questionnaire survey method and interview method.The study object is 25 students from class 4(experimental class)and 25 students from class 5(control class)in a senior high school in Xi’an.In this study,the author studied whether stratified group homework can promote the improvement of math scores of high school students by comparing the math scores of students in experimental class and control class on three examinations.This study examines the impact of stratified group homework on students’ math learning attitudes by conducting questionnaires and interviews about math assignments.The experiments in this study were conducted for two months.After comparing the math scores,questionnaire results and interview results of experimental class and control class,the research concluded: first,stratified group homework can improve students ’math learning performance;second,stratified group homework has a positive influence on students’ math learning attitude;third,stratified group homework can comprehensively consider students’ different learning levels;fourth,stratified group homework can better help students review and consolidate their knowledge. |
