Research On Evaluation Of Chemical Experimental Questions In High School Entrance Examination

In 2019,the Ministry of Education cancelled the syllabus of the High School Entrance Examination,and put forward suggestions on the test questions setting from various aspects.In the context of this reformation,as one of the important elements of the chemistry test questions,the requirements for experimental questions are also improved.In order to understand the current situation of the design of experimental questions,this paper constructs the analysis framework of the chemistry experiment questions for the high school entrance examination and select 33 sets of 2021 chemistry questions of high school entrance examination from different regions as research objects for analysis.Firstly,based on the review of relevant research,this paper determines the four elements of experimental questions: objective,design of the question,context,experimental activities.On this basis,this study constructs the "The design of Chemistry experimental questions" framework,which includes five dimensions:experimental knowledge,experimental ability,experimental activities,context design and problem design.Secondly,the framework is used to encode and analyze the experimental parts of the examination questions of different cities.The result shows that in the dimension of experimental knowledge,the focus of the exam is outstanding,but the distribution proportion of all kinds of knowledge and skills is unbalanced.The experimental activities are diversified,but the proportion of the setting of each exploration part is unevenly distributed.The examination focuses on the examination of medium level of experimental ability,but the frequency of examination for high level of experimental ability is relatively low.In terms of context,the examination focuses on the design of high-quality experimental context and tends to adopt diversified ways to present the situation,but the proportion of real context is relatively low.It's a pity that he proportion of open-ended questions is small and the closed-end question is predominant type.Finally,this study selected typical cases for analysis and improvement and put forward several suggestions for the setting of chemistry experimental questions.
