Research On The Design Of Chemistry Homework Based On Core Literacy

"Developing the core literacy of chemistry subject as the main purpose" is one of the basic concepts of the new curriculum standards.The core literacy of chemistry is not only a necessary scientific literacy for students,but also an important foundation for lifelong learning and development.Through sorting out domestic and foreign related literature on homework design based on core literacy,the analysis found that:in the current high school chemistry homework in our country,teachers generally arrange homework uniformly,paying attention to the scientific and systematic knowledge system,but there is also a lack of hierarchy and diversity.Sex,the phenomenon of less penetration of literacy in homework after school.Therefore,through the research on the design of chemistry homework based on core literacy,this research hopes to supplement and optimize routine tasks to futher develop and implement the cultivation of students’ core literacy.First,use the literature survey method to define the two concepts of core literacy and assignment design,based on constructivist learning theory,cognitive transfer theory,humanistic learning theory,and multiple intelligence theory.One students use the questionnaire survey method to understand the current situation of chemistry homework,analyze and summarize the existing problems,and put forward four principles and strategies for the design of after-school homework in teaching.And take the first class of "oxidation-reduction reaction" in the compulsory high school chemistry edition of the People’s Education Edition,and the first and second class hours of "Chemical Properties of Metals" as examples.The teaching practice is based on the designed teaching cases and homework based on core literacy.Select two parallel classes,the control class and the experimental class,for comparison.After the teaching practice,chemistry tests,questionnaire surveys and student interviews are used to analyze and summarize the results after practice.Use SPSS 23.0 software to analyze the data.By comparing the test scores of the two classes,it can be seen that the experimental class has an average score of 66.56 and the control class has an average score of 61.25.The control class has a smaller change in scores than before practice,while the experimental class The performance has improved significantly.Combined with the analysis of student questionnaires and student interviews,it can be seen that the core literacy-based homework design can not only increase students’ interest in chemistry and chemistry homework,but also benefit the development of students’ innovation and practical ability,and it can also be subtle Effectively develop and cultivate the core literacy of students.The research in this paper enriches the research on homework design based on core literacy and provides a reference for the teaching of frontline teachers.
