Research On Contextual Biology Examination Questions Proposition Based On The Evaluation System Of College Entrance Examination

Chinese college entrance examination evaluation system puts forward the concept of "one core,four layers and four wings",answers the question of "why test? What is tested?How to test?" The transformation from “ability conception” to “value-oriented,literacyoriented,ability-oriented,and knowledge-based” provides a theoretical and practical basis.The Chinese college entrance examination evaluation system clearly uses the context as the evaluation carrier.The general high school biology curriculum standard also clearly states that the core literacy of biology is the value,necessary knowledge,and key abilities shown in solving biological problems in real situations.Chemical test questions have become an effective tool for core literacy testing.The contextualized examination questions of biology are not only helpful for realizing the subject quality of the examination,but also conform to the characteristics and requirements of the nature of the subject.How to integrate the biological context into the test questions,and how to make high-quality biological contextualized test questions is worthy of in-depth study.Through literature analysis,this study understands the basic situation of the contextualized test questions in the foreign NAEP test questions and the domestic college entrance examination biology test questions,selects typical test cases for discussion,and derives the basic requirements of the prescriptive contextualized test questions.According to the analysis results,the strategy of setting high school biology contextual test questions was refined,and twelve high school biology contextual test questions were ordered according to the strategy.Then,consult with front-line proposition experts,evaluate the validity of the test questions,conduct test tests in a small range,and further modify the test questions.Conduct test questions in the front line of middle schools,collect statistical results,use winsteps3.66.0 software to run Rasch model to analyze the test questions,and further modify the test questions based on the feedback results.This research has drawn the following high school contextualized test question proposition strategies: First,refine the classification of context and contextual activities to form a contextualized test question proposition model;second,the contextualized test questions should be set closely with the background materials to prevent the problem from detaching.Question stems,reduce the appearance of "non-contextualized setting questions";Third,the setting of contextual test questions should pay attention to continuity,hierarchy and task orientation,and pay attention to the connection between the questions,and the difficulty should gradually increase layer by layer;Fourth,scientific and technological papers are an important source of material for contextualized test questions,and more rigorous and scientific advantages of scientific and technological papers can be used.Fifth,construct test questions with core values of biological characteristics and infiltrate core values.
