The aim of this study is to examine in what way teachers in upper secondary school who teaches non-language centered courses uses scaffolding within the theoretical context of language-based learning to support their students’ learning. The study will also examine if there is a difference depending on what subjects the teacher is licensed to teach in. The main methods used are observations and audio recordings of three different teachers during a total of six lessons. The material also consists of interviews with the observed teachers to give additional information about the teachers’ backgrounds and thoughts about language-based learning in relation to their teaching methods. The study is based on a sociocultural and cognitive approach along with the principles of scaffolding based in genre-based pedagogy and Jim Cummins’ theory on how to achieve language proficiency within a school-based contexed and its specialised domains. The results show that all teachers use scaffolding by creating an extensive context for learning within each domain. This contextual scaffolding helps the students learn the new language domain. The teachers also show variations in how they scaffold depending on the subject and student group with more abstract subjects being provided with more concrete exemplification. The conclusions drawn from this is that teachers use scaffolding to help students build the field of the domain and provide scaffolding according to the different subjects and student groups' current conditions and need for cognitive challenges.
