Situational Item Design For Domain-Specific Key Competence Assessment

Since the publication of the 2017 edition of the chemistry curriculum standards for ordinary senior high schools,the scientific and effective assessment of students' achievement of the core accomplishment has become the most important goal of the evaluation of chemistry education.Due to the great difference between the connotation of core literacy and the original knowledge and skills,the new curriculum standard stipulates that the test questions should examine the ability of students to solve practical problems based on the real situation,and then evaluate the level of core literacy.And theories,the paper design needs a new framework of foreign large literacy test for nearly 20 years of experience,"the evidence centered design(ECD)" model show great superiority in the literacy test design,this study based on ECD model provides the framework,combined with the new curriculum standards,chemical subject content and Roegiers situated proposition theory design and inspection,which is divided into the following five chapters:The first chapter is the introduction,which expounds the background of the topic,the significance of the research purpose and the content of the research method.The second chapter is the theoretical basis,mainly expounds the requirements of the new curriculum standard on the quality-oriented test questions,the evidence-centered design model and its sub-model,luo riye's situational typology and situational proposition theory,summarizes the process of test question design,and generates the situational label to evaluate the situational quality.The third chapter is a test design for identification of "macro and micro analysis" literacy as an example,based on the quality of academic standard,curriculum literacy level,development of subject characteristics test of student model,rules of evidence,measurement model and task model,the present model and combined model,generate test level 1 to level 4of the five situations theme 15 project item set.The fourth chapter is the chapter of test quality inspection and correction.The test results are processed by the one-dimensional Rasch model.Based on the reliability,degree of separation,degree of data model fitting,and white graph,unreasonable test questions are found.The fifth chapter is the research summary,which proves that ECD model can provide the basic framework for literacy test question design,and situational test question design needs to integrate multiple theories,summarizes the general experience of situational task design,reflects on the research shortcomings,and analyzes the research direction and feasibility of future situational test.
