CODI Main Test

- Examination of students' error patterns in the field of functions in a quantitative way - research questions: How often do typical error patterns occur among students? Which of them can be ascribed to underlying obstacles? Which of them turns out to be robust over time? - Test instrument and background available online at www.codi-test.de - Data set of 569 students in the main study (28 items); Data set of 168 students in the additional test (six months later) - Eight error patterns which occur among more than 10% of the students -Identification of four error patterns which seem to be particularly robust over a longer period of time

本数据集旨在以量化方法考察学生在函数领域的错误模式（error patterns），研究问题涵盖：学生群体中典型错误模式的发生频次如何？哪些错误模式可归因于潜在认知障碍？哪些错误模式在时间维度上表现出稳定性？测试工具及相关背景可通过www.codi-test.de在线获取。主研究数据集包含569名学生的作答数据（共28道测试题）；间隔六个月后的附加复测数据集包含168名学生的数据。本研究共识别出8种在超过10%的学生中出现的错误模式，并确定了4种在较长时间跨度内稳定性尤为突出的错误模式。
