At present, the reform of the college entrance examination is continuously developing in the direction of contextualized examination questions. High school contextualized biology examination questions are the focus of the test center researchers and biology teachers. However, there is still no systematic analysis theory on how to effectively analyze the internal characteristics of high school contextualized biology examination questions. The content parameters in Roegier's situation typology can reflect the internal characteristics of the situation. Therefore, based on the content parameters of Roegier situation typology, this study determined the content parameters of the high school biology contextualized examination questions by conducting an expert questionnaire survey, in order to provide an analytical theory for the research of high school biology contextualized examination questions.
