Analysis And Review Strategy Exploration Of Chemical Process Questions Based On The Evaluation System Of The College Entrance Examination

Since the 18 th National Congress of the CPC,the Party Central Committee has attached great importance to the reform of the examination enrollment system,and the new round of examination enrollment system reform launched in 2014 proposes to "basically build a modern education examination enrollment system with Chinese characteristics by 2020".To achieve this goal,the examination center of the Ministry of Education issued the "China College Entrance Examination Evaluation System" and "China College Entrance Examination Evaluation System Description".As the theoretical guidance and practical basis for the propositions of various subjects,the college entrance examination evaluation system plays an important role in the reform of basic education and the reform of the new college entrance examination in various provinces.Chemical process flow questions are an important part of chemistry test questions,which not only meet the requirements of the college entrance examination evaluation system,but also play a guiding and reference role in the teaching and test question system of the provinces that will soon implement the new college entrance examination.This paper takes the topic of chemical process flow as an example,combined with the college entrance examination evaluation system,analyzes the examination content and examination requirements of the national paper chemical process questions in the past five years,and explores the review strategy of chemical process flow questions.This paper uses literature research method and data analysis method to quantitatively and qualitatively analyze the chemical process questions in the national volume in the past five years from 2018 to 2022: firstly,the content of the chemical process question examination is defined by the method of qualitative analysis,and secondly,the necessary knowledge,key ability,subject literacy,core value,examination requirements and examination context of the chemical process question are statistically calculated by the method of quantitative analysis.It can be seen that the chemical process problem tests students’ ability to use the knowledge they have learned to solve problems in real situations,and pays attention to the examination of chemical concepts and thinking methods.Through the interview method,inductive summary method and survey research method,the interview investigation of the review strategy of chemical process problems was carried out from the teacher level,and the learning status of chemical process problems was investigated at the student level.At the same time,we can deeply understand the teaching situation of chemical process problems and the learning status of students.The survey shows that the traditional chemical process problem review is lacking in the construction knowledge system,and students are prone to psychological obstacles and fear to do the questions when they do not master the necessary knowledge well.According to the theoretical analysis and practical investigation,four review strategies for the chemical process of the college entrance examination are proposed:(1)return to the process flow of teaching materials to improve teaching efficiency;(2)Familiar with the process flow routine and overcome psychological barriers;(3)Consolidate the necessary knowledge of the process and improve the key capabilities;(4)Build a problem-solving model and cultivate scientific problem-solving ideas.The two teaching designs formulated based on the strategy were practiced in the experimental class,and the changes of students’ performance before and after the use of the review strategy were compared and analyzed by SPPSS software,and the corresponding student interviews were conducted,and the results showed that the review strategy proposed in this paper had a certain effect on improving students’ performance in chemical process questions.
