Entwicklung und Validierung eines Tests zur Erfassung der mathematikspezifischen professionellen Kompetenzen von frühpädagogischen Fachkräften

Previous studies show that the competences of teachers play a central role for the learning of children. However there has only been little research on preschools, which is also due to the lack of adequate tests. This paper presents a standardised test for the assessment of mathematics-specific professional competences of preschool teachers. Classic paper-pencil item formats and video-based items were developed and tested on the basis of a sample (N=112) of preschool teachers from Germany and Switzerland, all of them currently working as preschool teachers. The psychometric quality of the scales was examined on the basis of the Partial Credit Model. The findings indicate that the test is reliable und measures validly: Content validity is supported by the theory-based item development and the authenticity of the item content perceived by preschool teachers. The empirical replication of the three-dimensional competence structure and the mapping of predicted differences between groups (with different degrees of education and nationality) support the validity of the interpretation of test scores.
