Analysis Of Senior High School Chemistry Ability And Expression Based On Core Literacy

The Construction of Chinese College Entrance Examination Evaluation System,not only reversed the unscientific educational evaluation orientation,but also put forward the basic index to evaluate the quality of test items.Yunnan Province test is a comprehensive examination within the whole province.The results reflected by the test results can observe the knowledge of the candidates and the level of subject ability,so as to better prepare for the college entrance examination.Therefore,it is of great significance to analyze and study the questions of provincial test.However,the current analysis of test questions mainly focuses on the college entrance examination,and the provincial test questions are less.However,there are fewer analysis studies of provincial test questions from the perspective of core literacy and students’ answers.In this paper,the 2022 Yunnan Provincial test was analyzed and studied from the aspects of core literacy,academic quality standards,academic requirements and subject ability,and the Rasch model was used to test the overall quality,White chart and project fit degree of the provincial test questions to judge the quality of the order.Then,according to the answers of students in X School of Qilin District in the provincial tests,the performance of core literacy and subject ability of chemistry discipline is judged,and the performance of core literacy is compared with the overall level of Yunnan Province and Kunming City to find out the gap of X School.The following conclusions are drawn:(1)When examining the core literacy level,the four levels of literacy 1 are comprehensive,and the performance of students in X school in literacy 1 is better than the overall level of Yunnan province,and even reaches the overall level of Kunming city,while the four levels of literacy 2,3,4 and 5 are not comprehensive and the performance of students is lower than the overall level of Kunming City.Slightly higher than the overall level of Yunnan Province;In the examination of academic quality level,academic requirements in line with the curriculum standard of academic level grade examination proposition basis description;In the examination of subject ability,the levels of learning and understanding(A),application practice(B)and migration and innovation ability(C)are all involved.The examination of level A and level B is comprehensive and level B accounts for a large proportion.(2)Questions 13 and 27 in the second series of the province are more difficult,but generally speaking,the overall quality of the two testpapers is good.(3)Students have the best performance in Accomplishment 5,the worst performance in accomplishment 3,and good performance in accomplishment 1,Accomplishment 2 and accomplishment 4;The ability performance of A,B and C of the two test questions decreased in turn,and the students’ ability of A and B to solve problems in the two provinces was better than that in the one province.Finally,based on the results of the analysis of provincial test questions,this paper puts forward the following teaching suggestions from the perspective of improving the "literature-oriented" teaching effect:(1)Internalize students’ understanding of solving inorganic compound problems by using valence twodimensional graph;Design hierarchical teaching activities based on cognitive model and subject ability elements.(2)Strengthen the teaching pertinence of different stages and levels of ability development;The molecular structure analysis model of organic compounds was established.(3)Pay attention to the implementation of variable control ideas with the help of experimental exploration activities;Understand the prototype from multiple angles and pay attention to the mutual influence of balance.(4)Carry out teaching in the real and complex life background,promote the transformation of ideas and methods: help students apply the multi-correspondence relationship between life perspective and chemical perspective to solve complex and unfamiliar problems.(5)Attach importance to problem-evidence-conclusion reasoning and highlight the value of variables and their relationship;Design multiple types and levels of chemical experiment exploration activities.
