A mathematics competence test for Grade 1 children migrates from Germany to South Africa

摘要: This article presents the translation and adaptation process of a mathematics test for acquisition key mathematical (arithmetic) concepts by children from four to eight years age. The origin this was in Germany, whence it sourced researchers at University Johannesburg. A conceptual model hierarchical competence development forms theoretical foundation test. notion tested one-dimensional Rasch analysis, which confirmed structure with five levels ability. In process, imperative ascertain whether items had retained content original been allocated same as number pilot studies total 1 600 South African children, we focused on that different level, aiming find out result errors. analyses samples, discussing reflecting fit, especially did not fit well, ‘misfitting’ could mostly be attributed difficulties differences children’s strategies, generally altered model. final established after rephrasing critical items. has already 500 additional children. Results are presented discussed, focus Sesotho results.
