The study also explores how different grammatical constructions in mathematical problems affect students' calculations and how students experience the same types of tasks formulated with different grammar. The results show that the students meet a higher accessibility in the textbook test and that they experience tasks with more complicated grammar as more difficult. However, the results are not entirely clear regarding how grammar affects the students’ calculations. In more difficult math tasks, grammar seems to play a greater role than in tasks with less...
