Research On Chemistry Assignment Design In Grade One Of Senior High School To Promote The Development Of Core Literacy

The Chemistry Curriculum Standard of General Senior High School(2017 Edition)condenses the core literacy of chemistry.Chemistry core literacy embodies the correct values,essential character and crucial capability that can adapt to lifelong development.Assignment is an important link in the process of chemistry teaching and an important position for the cultivation of core literacy.Based on the literature research,it was found that some researchers had developed students' core literacy from the perspective of assignment,but the research was not deep enough.The purpose of this study was to further explore from this perspective,and strove to make the chemistry core literacy successful implementation of the reasonable assignment design.Through the investigation method,this paper investigated the current situation of chemistry assignment in grade one of senior high school and summarized the defects: heavy and repetitive assignment workload;single type and boring content;conservative evaluation methods;unimplemented the cultivation of core literacy.In order to solve the above defects,combined with the relevant literature research,the author summarized the theories of multiple intelligences,situational cognitive learning and developmental evaluation as the theoretical basis,and made an in-depth study of the design requirements of chemistry assignment in the curriculum standards.It was concluded that the assignment design to promote the development of core literacy should follow the principles of science,diversity,openness and development.Meanwhile,it need to be met the following characteristics,which are including that the quality reflects the high efficiency,the content is interesting,the material is situational,the form reflects diversity,and the evaluation has the characteristics of development.Based on the above,we designed assignment cases such as "chlorine and its compounds" and "redox reaction" in the textbook of senior one and drew a conclusion.The assignment design to promote the development of core literacy takes knowledge as the carrier and literacy development as the goal.We should deepen students' understanding of the connotation and laws of chemistry,cultivate their scientific attitude and sense of social responsibility.Improving their learning ability and transfer ability to cope with more challenging and complex tasks in the future.From the level of schools and teachers,this paper put forward some suggestions on chemistry assignment design to promote the development of core literacy: we should promote and implement the core literacy for a long time,fully mobilize the strength of the lesson preparation group,and establish a subject assignment question bank.;we need enhance the awareness of the study and application of chemistry core literacy,improve the ability to integrate chemistry curriculum resources,and pay attention to the research on academic quality standards.
