2017-2019 Research On UK CAIE A-Level Chemistry Exam Questions

The A-Level is called the British General Certificate of Education Advanced-Level,which is a unified qualification examination implemented by British universities across the country.The thesis researches on the 2017-2019 A-Level chemistry examination questions,and the research results provide suggestions for the teaching of my country's international edition teachers,and provide reference value for my country's college entrance examination reform.This thesis introduces the A-Level system,analyzes the test question types and structure,evaluation objectives and content of the A-Level questions compiled by the Cambrige Assessment Internation Education,and summarizes the characteristics of the A-level.Based on the rating objectives of the syllabus issued by CAIE and the SOLO classification theory standard,the 2017-2019 AS-Level and A-Level test questions are classified into SOLO levels.All test questions are divided into four thinking levels of U,M,R,and E.Through vertical and horizontal comparisons,it is concluded that the proportion of U-level scores in AS-Level test questions has a low and stable trend.The U-level scores in the A-Level test questions have the lowest percentage,and the M-level scores in the AS-Level account for the highest proportion of all levels.The proportion of M-Level is relatively high and fluctuates greatly;the proportion of AS-Level at level R is second only to the proportion of level M,and the proportion of A-Level test questions at level R is the largest,and the overall trend is rising.The proportion is the lowest in the AS-Level test.Compared with the AS-Level test questions,the E-level score of the A-Level has a larger proportion and less fluctuation.Using SPSS software to establish a linear regression equation for the pass rate of exam A and the level of SOLO.The relationship between the pass rate of AS-Level exam and the level of SOLO is Y=1.325+0.686 M,indicating that the pass rate of A level is positively correlated with M relationship.The relationship between the A-level pass rate of the A-Level exam and the SOLO level distribution is Y=59.371-0.893 R,indicating that the A-level pass rate is negatively correlated with R.When the R-level ratio increases,the A-level pass rate decreases;or the formation of two The meta-regression equation model is Y=66.015-0.560R-0.945 E.The pass rate of A grade is negatively correlated with both R and E.Since the ratio coefficient of the R grade is smaller than the E grade,it shows that the score ratio of the E grade is relative to the A grade pass rate.The impact is greater than the ratio of R-level scores.
