Learning trajectory describes the student's learning progress or steps in one area through which teaching and learning can be linked. The cognitive diagnostic model (CDM) is an emerging evaluation theory in education measures. Researchers can determine students' mastery of fine-grained knowledge points by describing the learning trajectory based on CDM. The present study is based on the Trends in International Mathematics and Science Study (TIMSS) 2019, particularly, 21 mathematical items in the fourth grade. It analyzes the response data of 2,854 students from 17 countries from 10 attributes based on CDM. This study explores students' different learning trajectories in the content field by analyzing the relationships between knowledge states and attribute patterns. The study found that the 17 countries differ in learning trajectories but have commonalities. The learning starting points of 17 countries can be roughly divided into two categories and geometry attribute and fractions and decimals attribute are the last two attributes to master.
学习轨迹描述了学生在一个领域的学习进展或步骤，通过它可以将教学联系起来。认知诊断模型（CDM）是教育测量中一种新兴的评价理论。研究人员可以通过基于CDM描述学习轨迹来确定学生对细粒度知识点的掌握情况。本研究基于2019年国际数学和科学趋势研究（TIMSS），特别是四年级的21个数学项目。它基于CDM分析了来自17个国家的2854名学生在10个属性上的回答数据。本研究通过分析知识状态与属性模式之间的关系，探索了学生在内容领域的不同学习轨迹。研究发现，17个国家在学习轨迹上存在差异，但也有共性。17个国家的学习起点大致可分为两类，几何属性和分数与小数属性是最后掌握的两个属性。
