The aim of this study is to investigate the similarities/differences in the views on and practices of grammar teaching of a Swedish teacher of English (FL – Foreign Language) and a UK teacher of English (L1 – First Language). Furthermore, the study tries to explain how the differences found in the comparison can be connected to each country’s different steering documents and to the different teaching conditions involved in teaching English to L1 learners compared to FL learners. The two participating teachers were both interviewed and observed. The results of this study show that the teachers’ grammar practices are very similar since they include explicit formal instruction both inductively and deductively, but with a focus on the latter. These are typical ‘Focus on FormS’ related practices even though both teachers want to achieve a ‘Focus on Form’ directed practice. Furthermore, both teachers use metalanguage in their teaching. The main difference between the teachers’ grammar approaches are the aims that they have with their teaching. The UK teacher aims at plain accuracy in her pupils’ written production whereas the Swedish teacher aims at developing all-round communicative abilities among her pupils. This is explained with the different accuracy-focus which each country’s steering documents hold.
