Test instrument of the working group "cosh - Cooperation School-University" calibrated on more than 2500 students of different school types in Baden-Württemberg.
In the first few weeks of the school year, the test instrument, developed within the framework of the cosh joint project at the HfT Stuttgart, was calibrated at schools from all administrative districts of Baden-Württemberg. A total of 2631 pupils from 127 classes took part in the test. The test was carried out at both general education and vocational grammar schools as well as at other vocational schools (vocational colleges, upper vocational schools), the completion of which entitles students to study at a HAW.
The aim of the calibration is to enable students participating in the test in the future to classify their personal test result in a comparison group beyond the absolute results.
The test met with great interest among teachers, especially since, according to the concept of the Ministry of Education and Cultural Affairs, priority should be given to determining the learning level at the beginning of the new school year due to previous school closures. Since no such instrument yet exists for the transition from lower to upper secondary level, the use of our mathematics achievement test, newly developed in 2019/20, could be helpful. The development of the test was based on the Minimum Requirements Catalogue for Mathematics (Version 2.0) for studies in WiMINT subjects, which was already published by cosh in 2014 and which has gained recognition throughout Germany. The test is a diagnostic tool for early detection of knowledge gaps in mathematics. It was designed primarily as a self-test for students of secondary level II and is intended to provide differentiated individual feedback on the level of knowledge in several sub-areas. To this end, the calibration sample will now be used in the further course of the project to validate the model assumption, which has so far been formulated on the basis of a smaller sample, under psychometric aspects.
