Research On The Preparation Of Junior Middle School Biology Open Test Questions

With the publication of Biology Curriculum Standards(2017 Edition)in general high schools,the implementation of biology core literacy has become one of the research hot spots in the field of biology pedagogy.As a tool to measure students' biology core literacy,the compilation of exam questions is particularly important.Open question means that in a real situation,students can find different ways to solve problems from different perspectives,or get different results.Therefore,open question is an important question type to measure students' thinking of seeking differences,critical thinking and scientific thinking.This paper mainly analyzes the examination of open questions in the senior high school entrance examination at home and abroad,taking IGCSE and biology questions in the senior high school entrance examination in China as the research objects,trying to compare and summarize the open questions among them,and summing up some shortcomings in the preparation of open questions in China,such as fewer open questions,less openness and imperfect scoring standards;Through expounding the key points of compiling open questions,including the process of designing questions,the principles of compiling questions,and the grading standards of questions,the author tried to compile the open questions of middle school biology,tested three classes with the questions,scored with SOLO classification theory,studied and analyzed the experimental data,and concluded that students' ability to solve open questions is relatively weak and their experience in solving open questions is scarce,and SOLO classification theory has certain defects in grading different types of open questions.Finally,this study is analyzed and summarized,and the future research is also prospected.
