Research On Subjective Questions Of Chemistry In Jiangsu College Entrance Examination Based On SOLO Classification Theory

As the main way of college enrollment and selection,the college entrance examination has attracted wide attention from all walks of life.It is also a concrete manifestation of the basic education curriculum reform,and has a strong guiding role in teaching and learning.The examination questions can reflect the demands of the country on education and the talent training mechanism at a certain period.Therefore,the evaluation and analysis of the examination questions has always been a hot topic in the study of education.Under the guidance of SOLO classification theory,we set up the SOLO level dividing standard of test questions,and divided the college entrance examination questions into four levels:U level,M level,R level and E level.Taking the above criteria as an evaluation tool,we deconstructed and analyzed the subjective questions of chemistry in Jiangsu college entrance examination in the past 2013-2017 years,and got the SOLO level distribution characteristics and variation tendency of chemistry test questions in recent five years.Based on this,we quantitatively studied the relationship between the SOLO score and the difficulty and the discrimination degree by using SPSS software.Through the study,it is found that in the last five years of Jiangsu college entrance examination,the proportion of M and E levels is relatively stable,and the U level and the R level fluctuate greatly.The proportion of R level is the largest,ranging from 30.9%to 51.5%.It decreased from year to year in 2013-2016 years,and increased in 2017.The proportion of the U level is between 17.6%and 29.4%,and the average value is 22.3%.At all levels,it is only lower than the R level.The proportion of M level is from 17.6%to 20.6%,showing an upward trend in the stability.The E level is the least,with a proportion of 13.2%?20.6%,but it has increased year by year in the last five years.The difficulty coefficient of test questions is mainly influenced by R level and E level,Y=0.909-0.837R-0.72E.The increase of R and E levels will reduce the difficulty coefficient,and the R level will have a greater impact.The overall division of test questions is mainly influenced by U level,M level and E level,Y=0.692+0.324U+0.236M+0.164E.The increase of U,M and E levels will increase the overall division of the test,and the U level will have the greatest influence,followed by the M and E levels.The first level division of test questions is influenced by R level and E level,Y1=0.104+0.507R+0.581E.The increase of R and E levels will increase the first level division.The third level division is positively correlated with the score of U and E,and negatively related to the score of R level.On the basis of the above conclusions,relevant high school teaching suggestions are put forward.
