Research On The Evaluation Of New College Entrance Examination Chemistry Questions Based On Academic Quality Standards

The 《General High School Chemistry Curriculum Standard（2017 Edition）》 adds a new academic quality standard,which is the academic achievement performance of students after completing the course study at each stage,and serves as an important basis for the formulation of test questions and daily teaching evaluation.After the reform of the new college entrance examination,chemistry has become an elective subject,and more provinces have begun to design their own test questions.The main purpose of this paper is to analyze and evaluate college entrance examination chemistry questions based on academic quality standards.The selected research objects are five sets of new college entrance examination papers in 2021,including the Hebei,Guangdong,Hunan,Hubei and Fujian papers,as well as the National I Volume in 2020 and 2019,a total of seven sets of papers.Based on the academic quality standards and the evaluation system of the college entrance examination,this paper constructs a quantitative evaluation framework for four levels of chemistry subject literacy.The four dimensions refer to chemical concepts,thinking methods,practice exploration,and attitude responsibility.The four levels are based on Cognitive level requirements and situational complexity are divided into different levels from low to high.Use the framework to code test questions and then the output of the rater consistency test via Cohen’s kappa coefficient indicates that the quantitative analysis framework of the test questions has a high degree of reliability and operability.Subsequently,each set of college entrance examination chemistry papers is identified at the level of academic quality of the questions and the four aspects of subject literacy using the test analysis framework,and each set of papers is compared and analyzed side-by-side.The results showed that the difficulty level of the Hebei Volume is the closest to that of the National Volume I of the previous two years,and it is even more difficult.The overall difficulty of the other2021 new college entrance examination papers is lower than that of the previous two years’ National I papers.By comparing the distribution of the four aspects of the subject literacy,it is found that the seven sets of test papers have roughly the same proportion of each dimension of subject literacy,except for the Hubei paper,where the proportion of ’attitude and responsibility’ is significantly lower than in the other papers.Finally,based on the results of the evaluation of the test questions and the interviews with front-line teachers,two pedagogical suggestions are made:（1）to build practical examples of thematic teaching based on real-life contexts;and（2）teachers to enhance their learning of the connotations of "academic quality standards".
