Analysis And Consideration On The Typical Test Questions Of 2019 National Chemistry High School Entrance Exam

The typical questions of the chemistry high school entrance examination have developed from memory-based to inquisitive,applied and open,but after analysis,it is found that some typical questions still need to be further improved in the presentation form,content,scoring standards and other aspects of some middle school test papers.The study of the questions in the middle school chemistry examination is conducive to promoting the reform of junior middle school chemistry curriculum,exploring the creative ideas of the propositions in the middle school chemistry examination,promoting the development of students' chemistry core literacy,and facilitating the development of classroom teaching in the right direction.This topic based on the situated cognition theory,ECD evaluation theory and SOLO classification theory as the theoretical basis,combined with "college entrance examination evaluation system in China" and "compulsory education chemistry curriculum standard",according to the principles of objectivity,science,consistency and compliance,analyzes the typical chemistry questions in the middle school entrance examination from the aspects of subject knowledge,key ability,core literacy and context carrier.20 chemistry examination papers from all over the country in 2019 were randomlyselected,including the eastern,southern,western,northern and central regions of China,as the research samples of this paper.Of the 20 papers,10 were provincial-level,or about 53 percent of the national total,and the other 10 were city-level,or about 9 percent.This topic analyzes the test questions in these sample papers as a whole,including the topic knowledge of Chemistry,key ability,core accomplishment and context carrier in Chemistry exams and so on.Through the analysis and comparison of the subject knowledge,the key ability,the core literacy and the context carrier,this topic probes into the thesis bias and emphasis,the successful experience and the aspects that need to be improved of this year's test paper.Through the statistical analysis of the questions,although most questions can take the real situation as the carrier,it is found that some of the typical chemistry questions in the middle school entrance examination have the following problems:(1)Some tests focus on memory over comprehension;(2)The context carier of some questions is designed by"conjecture and analogy",and its authenticity is biased,failing to embody the core value of chemistry;(3)Some questions are unclear,the content is beyond the requirements of curriculum standards or students'cognitive level.Based on the statistical analysis of the typical chemistry test questions in the senior high school entrance examination,the following suggestions are put forward:(1)Improve subject understanding and moderately increase the openness of test questions;(2)Pay attention to the selection and design of test situation;(3)Strengthen the test of experimental operation ability.The results of this research are expected to be of reference value to the renewal of junior middle school chemistry teaching ideas,the reform of teaching methods and the implementation of teaching evaluation.
