Development and validation of an instrument for assessment literacy of mathematics teachers

外部学校成绩测试为教师提供评估数据，可用于评估教学并为学生开发适应性学习机会。这些数据的使用要求教师能够解释统计信息并得出结论，以改进教学。这方面的专业能力被称为评估素养。本研究项目旨在开发一种评估数学教师素养的认知测试，该测试分为三个层次：1)注意数据，2)解释数据和3)构建教学含义。这些级别将通过测试项目进行操作，并由一组教师进行试点。测试开发完成后，将对柏林和勃兰登堡的数学教师进行验证性研究。本研究将探讨效度的不同方面，包括内容、结构和标准效度。该项目的研究结果有助于更好地从理论和实证角度理解教师评价素养。由此产生的测试工具可用于干预研究中教师专业能力的诊断和发展。

External school achievement tests provide teachers with assessment data that can be used to evaluate instruction and to develop adaptive learning opportunities for students. The use of this data requires teachers to be able to interpret statistical information and draw conclusions for the improvement of instructions. This aspect of professional competence is referred to as assessment literacy. The research project aims to develop a cognitive test for assessment literacy of mathematics teachers that distinguishes three levels: 1) noticing data, 2) interpreting data and 3) constructing implications for instruction. These levels will be operationalized with test items and piloted with a group of teachers. After the test development, a validation study with mathematics teachers in Berlin and Brandenburg will be conducted. This study will examine different aspects of validity including content, construct, and criterion validity. The results of this project contribute to a better theoretical and empirical understand-ing of assessment literacy of teachers. The resulting test instrument can be used for diagnosing and developing teachers' professional competence within intervention studies.
