Research On The Effective Chemistry Assignment In Senior High School From The Perspective Of Core Literacy

The core chemistry literacy is clearly put forward in the 2017 curriculum standard,which is the specific embodiment of students' comprehensive quality and the basic demand of education value of chemistry subjects under the core values.Therefore,the standard of chemical literacy as a chemical effective operation is in line with the development of students and the requirements of disciplines.It is necessary to study the conflict between the lack of core literacy in chemical effective operation research and the urgent need to implement core literacy in current education and teaching.The author uses the literature research method to sort out the theory of effective operation and current research situation at home and abroad,and defines the the relevant theories of effective homework and the research status at home and abroad,and defines effective operation and effective operation standards.the questionnaire survey method was used to investigate the current situation of high school chemistry homework,and the interview method was used to investigate the current situation of chemistry homework in high school.According to the survey and interview results,the common problems in chemical operation are summarized,that is,the core literacy training degree in effective operation is not enough;the source of arrangement is single,lack of interest and innovation;the form of work arrangement is single,lack of cooperation and inquiry;the content of assignment is lack of typical science;the arrangement is lack of hierarchy,and rarely involves layered operation,ect.According to the problems existing in the current chemical operation,the factors of effective operation and the effective operation standards,the corresponding strategies to improve the effectiveness of chemical operation are put forward,that is,to establish the correct concept of the chemical operation concept;pay attention to the subjectivity of students are properly select the content of chemical operation;Choose the type of chemical homework properly;Set the hierarchical operation according to the content of the homework.Through research,it can be known that the cultivation of core literacy in chemical operation is very necessary,which should attract the attention of the majority of education researchers and front-line teachers.The design of effective chemical operationcontent must meet the requirements of chemical core literacy,and effective chemical operation should serve the cultivation of all-round development of people.
