Many pupils today struggle to develop their writing skills. According to the Swedish curriculum (2022, p. 230) teachers should motivate and engage pupils in different ways to support their writing development. Writing development has been an important pedagogical issue, which caught our attention and led us to conduct a study about how motivation can contribute to developing students' writing skills. The purpose with this study was to examine how motivation can support writing development in the Swedish subject, and to analyze possible connections between motivation and writing ability in primary school students. Through a systematic analysis of previous research, we identified different perspectives and factors connected to writing development and motivation. The articles that were reviewed were chosen through search platforms named ERIC (EBSCO) and SwePub.Results show that motivation is a central factor to promote students' writing development and that it can stimulate students' learning in different ways. The study identifies three main strategies for maintaining motivation: (1) use of digital tools, (2) strengthening of student self-confidence, interests and attitudes, and (3) creating meaningful writing assignments. The analysis of these strategies show that students with high motivation have a more considerable writing development compared to students with lower motivation. Primarily, this is clearly shown among students in grade 4-6.
