Resumen
Digital teaching interventions allow for tailor-made university teaching. This is especially relevant for teacher education, where applicable professional teaching knowledge needs to be promoted for later professional success. Digital teaching tools have been shown to be a promising supplement for this purpose. Even though the corresponding demands in teacher education have been increasing in recent years, the need to develop digital learning tools usable in instruction is still urgent. The TWIND project develops digital learning tools for teacher education and evaluates them in a quasi-experimental design. The present work investigates the usability and application of these newly developed tools. Sixty-three trainee teachers worked independently over four weeks with one of two digital learning tools, focusing on either ?Multilingualism in Classrooms? or ?Professional Communication in Classrooms.? This study includes a pre-post-test of pedagogical knowledge facets as well as student and instructor ratings on the digital tools. The digital learning tools led to a positive change in the respective target facets of pedagogical knowledge. The student and instructor feedback reflected positively on the usability and usefulness of the new digital tools. Based on these findings, the limitations of the study as well as implications for further research and teacher education practice have been outlined.
