The purpose of this study was to examine the writing skills of 7th- and 8th-grade students with a high proportion of migration background in North Rhine-Westphalia, Germany. The study was part of the SchriFT project (2017-20), funded by the Federal Ministry of Education and Research. A writing task was given on the topic: "Why can we only make assumptions about many past events?" As an answer to the task, the students had to write a historical explanation that took into account the epistemological principles of historical reasoning. The students' writing was analysed using a category system, and their historical knowledge was assessed through a knowledge test. The results showed that the students possess diverse levels of writing skills, with few producing elaborate explanations, and most struggling with the subject-specific language and reasoning skills. The study also highlights the potential for genre-based writing approaches in history education. The results suggest that many students perceive history as an image of the past and have limited understanding of historical reasoning. Further research is needed to investigate the influence of motivation and interest on language learning.
