Study On The Effectiveness Of High School Chemistry Assignments Based On Core Literacy

Discipline core literacy is the embodiment of students' comprehensive quality and an important part of core literacy.The core literacy of the chemistry discipline reflects the educating requirements of the chemistry course,and demonstrates that through the learning of the chemistry course,students gradually develop correct values,essential qualities and key abilities.Chemistry homework is a necessary part of the chemistry course.The completion of chemistry homework achieves the goal of consolidating knowledge and developing abilities.However,there are still many problems with today's chemical assignments,such as fixed assignment types,no differences in assignment levels,and heavy workloads.Inefficient chemical assignments will also affect the cultivation of core literacy of students in chemistry.Therefore,this article conducts research on how to improve the effectiveness of high school chemistry work based on core literacy.First,understand the current situation of high school chemistry operations through questionnaires,and grasp the existing problems in high school chemistry operations.Second,based on core literacy to improve the effectiveness of chemistry operations,put forward corresponding strategies in the areas of operation design,operation completion and operation feedback;Again,three effective assignment modes are designed,that is,preview assignments,problem assignments,and inquiry assignments.For pre-reading assignments and problem-based assignments,the process of analyzing textbooks and learning conditions,studying curriculum standards,assignment design,assignment implementation,and analysis of assignment advantages has been adopted to achieve the efficiency of chemistry assignments and training based on meeting the academic requirements of the curriculum The purpose of student core literacy;for inquiry work,the process of determining topics,formulating plans,implementing plans,and summarizing topics to complete the cultivation process from knowledge to abilities to literacy is the advanced learning of subject core literacy development.The preparatory assignments are based on the case of "chemical reaction and energy change" and "combustion heat and energy";the problem-based assignments are based on the "chemical reaction rate" as the theme;Case study on the topic "Fluorine groundwater".Two parallel classes were selected in the practice school,which were used as experimental classes and control classes for practical research.On the one hand,we collect the monthly test scores of chemistry subjects and use SPSS data analysis software to visualize the practice results.On the other hand,we use interview methods to investigate the attitudes of students at the high,middle,and low levels to the new assignment mode.Research shows that the new assignment mode has an impact on student performance,and the passing rate and the excellent rate of the experimental class have increased.Moreover,the new assignment mode levels are in line with students at different stages,and based on the rational design of the assignment,they have attracted students.The interest in completing the homework,the effectiveness of the homework has been improved,and the core literacy of the students in the chemistry discipline has beendeveloped.
