| According to the requirements of the 2022 new version of the compulsory education chemistry curriculum standard,on the premise of ensuring basic homework,we should increase practical homework,flexible homework and interdisciplinary homework,reduce the workload of homework,scientifically design unit homework,reflect the integrity,diversity,selectivity and advancement,and the content,type,difficulty,quantity and completion time of homework should conform to the actual situation of students [1].At present,most of our teachers often overlook the individual differences of students and preserve the unity of homework assignments.In this way,the function of verifying students’ mastery of knowledge through homework cannot be fully utilized,nor can it achieve differentiated development of students,nor can it improve their comprehensive abilities.Therefore,it is particularly important to conduct research on hierarchical homework for students with different academic backgrounds.I will divide this paper into the following stages.In the first stage,a questionnaire survey was conducted to gain an understanding of the current situation of chemistry homework assignments for ninth graders.It was found that the current homework assignment situation is still a one-size-fits-all model,which does not fully meet the differentiated needs of students.The traditional homework model will create certain pressure on students with learning difficulties,while there are certain limitations on the ability development of students with excellent academic performance.Based on the requirements of the current new curriculum standards and theoretical knowledge of education,the necessity of layering homework design is analyzed.In the second stage,by reviewing a large number of literature reviews,we will gain an understanding of the current cutting-edge theories on hierarchical homework design both domestically and internationally,understand the degree of research on this topic at this stage,analyze the research purpose and significance of this paper,fully understand the definition of homework and the relevant theoretical basis,and provide a basis for homework design.In the third stage,based on the existing teaching experience,literature and theoretical knowledge,it is concluded that the design of layered homework should reduce blindness,uniformity,strengthen pertinence,practicality and selectivity.By improving the quality of homework,students’ learning efficiency and comprehensive ability can be improved.Based on this,feasible layered homework is designed and studied in the control class and the experimental class to preset the experimental results.In the fourth stage,the layered homework design is applied to practical teaching.After a period of time,a survey questionnaire is conducted on the control class and experimental class.Pre and post tests are conducted on students’ attitudes towards chemistry,quality comparison of homework completion,efficiency of homework completion,and changes in periodical grades.Through data analysis,with layered homework,students’ enthusiasm for Chemistry learning as well as the the quality of homework completion and improvements of grades are all positively reflected.The quality of homework completion and the improvement of grades are both positively reflected.The layered homework design is beneficial for students’ time management,learning attitude change,ability improvement,and grades.In the fifth stage,the achievements of this paper are summarized and prospected.Through this practical attempt and exploration,the author’s confidence in hierarchical homework design has been enhanced.I believe that as long as teachers are willing to persist,design with care based on the learning situation,and students are willing to trust and try,over time,it will be of long-term help to students’ interest in learning,efficient completion of homework after class,and steady improvement of grades... |
