| The college entrance examination is the largest,the most widely involved and the largest number of participants in the annual examination.The influence and importance of the college entrance examination in China cannot be ignored.The trend of college entrance examination affects the rhythm of examinees all the time,The annual college entrance examination papers are also first-hand resources for teachers to rush to study.Through examination paper analysis,we can know the examination scope of the test and master the requirements of the students’ ability,it helps to understand the adaptability of students to test,find out problems in teaching in time,and make teaching plans better.This paper is based on the chemical examination papers of the college entrance examination in Henan Province in 2008-2017,the analysis from these aspects: The proportion of each knowledge module in the annual examination papers,the degree of cognitive examination,the ability to examine the type of questions and the emphasis,the tightness of the relationship between the propositional background and the production and life,the core literacy and cross-disciplinary examination,and the combination of the syllabus and the curriculum standard,inorder to insight into the characteristics of the examination papers at all levels.The results of the study are summarized as: The "basic theory of chemistry" module has the largest value proposition in the past ten years;The cognition level of organic chemistry and chemical experiment is relatively high.;The chemistry exam paper focuses on examinee’s ability of interpretation,analysis,application,logic,divergence,language expression;The direction of college entrance examination has changed from the emphasis on knowledge in the past to the current tendency towards conception of emotion,attitude and values.More emphasis has been placed on the examination of scientific literacy;Pay attention to the guidance of "scientific attitude and social responsibility";Pay attention to the comprehensive utilization of multidisciplinary knowledge;The background of college entrance examination is more life oriented and practical;The main body of chemistry education has changed from teachers in the past to students nowadays.The paper analyzes situation about the loss of score of the chemistry examination paper in Henan Province in the past 2014-2017 years by means of recycling paper,gained knowledge points which lost more scores,namely the "chemical reaction rate and chemical equilibrium" in the "chemical basic theory" module and the "isomerism" in the "organic chemical basis" module.And there are many factors associated with the loss of score,such as the lack of ability behind the questions type,the lack of cognition of knowledge from all angles,and insufficient in teaching.Based on the analysis of test papers,some inspiring suggestions are given in the process of teaching: Pay attention to the training of the ability behind the various knowledge points;Pay attention to students as the teaching center;Pay attention to the combination of theoretical knowledge and practical application;Pay attention to the relationship between "scientific attitude and social responsibility" and daily teaching;Emphasizing the essence of chemical knowledge and designing and opening experimental verification;Focus on cultivating students’ ability to use mathematical and other multidisciplinary skills to solve chemical problems.Two teaching cases are designed around the knowledge of "chemical reaction rate and chemical equilibrium",and take the teaching case as the clue,the key factors in the teaching enlightenment based on test paper analysis are incorporated into the design of teaching cases.Teaching on the basis of these two teaching cases on the "experimental class",integrate knowledge points related questions into a set of test papers for classroom testing of "experimental classes" and "control classes" students.From the test results,the average score rate of "experimental class" is 73.3%,and the average score rate of "control class" is 57.7%,it can be seen that the use of two teaching cases in the class average score rate increased by 15.6 percentage points,and reduces the loss rate. |
