| This study is based on the teaching practice phenomenon of high school students who have undergone two years of learning,but the cultivation of core competencies is not effective.It investigates the characteristics of homework that can effectively improve students’ core competencies in high school physics.This study found the reasons for the inefficiency of traditional homework,namely,the failure to trigger students’ deep learning at a glance,resulting in students forgetting the content quickly and being forced to "re learn and rework" in subsequent learning,which indirectly increases the total number of exercises.A feasible corrective plan is proposed.This study proposes a solution to this dilemma through efficient homework,which includes four principles: goal oriented principle,subjectivity principle,hierarchy principle,and diversity principle.Based on these principles,five basic processes for college homework design are proposed,namely scientific setting of homework goals,analysis of corresponding core competencies,selection of extracurricular exercises,integration of extracurricular exercises,and deliberate training for difficult situations.This study conducted a two-month teaching practice of the four principles and five steps mentioned above in two high school students’ political elective courses at W School in Y City,from September 2022 to October 2022.After testing with quasi experimental research,questionnaire survey,and interview methods,the following conclusions were drawn:Firstly,efficient homework based on subject core competencies can significantly improve the subject performance of high school students.Comparing the physical test scores before and after the experiment,it can be seen that there was no significant difference before the experiment(p=0.96>0.05),but there was a significant difference after the experiment(p<0.05);Secondly,efficient homework based on subject core competencies can indeed improve students’ core competencies.According to the survey questionnaire data,before the experiment,the core competencies of the two classes were very close(p>0.05),and there was no significant difference.After the experiment,there was a significant difference(p<0.05)in the core competencies of the two classes,with the attitude of the reference class remaining basically unchanged.The experimental class was "regular".Thirdly,through interview data,we have also learned that efficient homework based on subject core competencies is relatively simple in form and can be tedious in the completion process.Therefore,there is still room for improvement in this area. |
