ETVis: a visual analytics system for high school entrance examination results and mobility patterns

The High School Entrance Examinations play a crucial role in many educational systems around the world. They are essential for assessing and placing students appropriately. In-depth analysis of student mobility and school performance in these examinations can contribute to improving teaching methods, optimizing the allocation of educational resources, and evaluating education quality. However, existing methods have mainly focused on the aggregate analysis of examination scores from summary views, lacking detailed insights into individual school disparities in performance and mobility patterns. To provide a comprehensive analysis of the High School Entrance Examinations, we propose a visualization analysis system named ETVis. This system allows education experts to explore the trends of student mobility within districts and compare the educational quality between different schools. The system offers three types of views at different levels: The student mobility view displays student mobility from junior high schools to senior high schools; the subject view presents scoring rate of different subjects; and the answer sheet view details scoring rate of each question. Through three case studies and evaluations by relevant experts, the results confirmed that ETVis can provide users with comprehensive data presentation and effectively analyze district education quality.
