Based On The SOLO Taxonomy Theory Analysis Of Chemical Papers In Guangdong Province High School Entrance Examination

As an important examination to select outstanding talents for senior high school,the middle school entrance examination is also a key link between junior high school and senior high school.With the new curriculum reform and the introduction of chemical core literacy,the transition from the previous emphasis on "knowledge as the core" examination goal to "emphasis on ability as the core" goal.The secondary examination has a profound influence on the reform of basic education,especially on the further promotion of curriculum reform and the effective implementation of quality education,in which the significance of the local significance and role is self-evident.Therefore,it is very necessary to study the ability structure of the chemistry test paper in the middle school examination.Under the guidance of the theory of classification and evaluation of the structure of learning achievement SOLO,which is originally meant to be observable,and combined with the curriculum standard,this paper makes a statistical analysis of the chemical examination questions in Guangdong Province and Guangzhou City in the past three years from 2017-2019.According to the level of thinking presented by the examinee in answering the specific questions,the chemical test questions in the middle school are divided into four levels: single point structure level(U),multi-point structure level(M),correlation structure level(R)and correlation structure level.abstract extended structure level(E).Through this theory,the author worked out a two-way detailed list of knowledge points,and made a more detailed analysis of the multiple choice questions part of the chemistry test paper in the last three years.At the same time,combined with the curriculum standard,the subjective questions part is also analyzed statistically.And on the basis of this analysis,from the horizontal and vertical two aspects of Guangdong Province and Guangzhou City in 2017-2019 nearlythree years of the chemical examination of each SOLO level of the score of the proportion of the following conclusions:1.From the point of view of the contents of the course,the contents of the chemical examination papers in Guangdong Province and Guangzhou City cover all the contents of the courses required by the curriculum standards,and the emphasis is on the chemicals around them,accounting for about 40% of the scores.At the same time,they pay great attention to students' experimental ability and students' scientific inquiry ability.In this part,the proportion of scores in Guangzhou examination will be higher than that in Guangdong Province.2.The distribution of the SOLO levels of the chemical examination questions in Guangdong Province and Guangzhou City is a single peak,and the M level is at its peak.The proportion of the chemical examination questions in Guangdong Province has exceeded 50% in the past three years,while the proportion of the chemical examination questions in Guangzhou City has fluctuated between 47% and 54%.U level test questions are mainly to reduce the difficulty of the examination papers,Guangzhou City this part of the examination questions account for a much higher proportion than Guangdong Province,especially in 2017 and 2018 in the two years,the U level of 40% left and right,and the U M level reached 88%,and then the R level of 12%,there is no E level,the overall difficulty of the test paper and the degree of differentiation are far lower than the Guangdong Province examination of the chemical test paper.Perhaps propositional experts are also aware of this problem,in2019 in Guangzhou City in the examination of the chemical examination paper in the difficulty and the degree of distinction has been significantly improved.3.the distribution of scores of each SOLO level in the chemistry test in guangdong province in the past three years has changed little,especially in the two parts of multi-point(M)and extended abstract(R)structure level,the score changes around 1point,and the overall stability of the test paper is well controlled.while the overall SOLO hierarchy changes very little in 2017-2019,the U level test questions are greatly reduced,at the same time,the examination of higher-order thinking ability is obviously increased,at the same time,there are E level test questions,more in linewith the test questions ability-oriented examination objectives,the test paper as a whole is relatively more reasonable.
