The aim of the paper is to explore verbal interactions during group tutoring of undergraduate’s thesis in teacher education program. The point of departure is that the public authority that oversees higher education institutions, The Swedish National Agency for Higher Education (2006), has questioned the quality of the theses at undergraduate and master level at the teacher education programs in Sweden. The main critic aimed at the theses concerns lack of academic qualities, such as failing theoretic awareness, weak analysis, normativity and lack of critical thinking. The teacher education program in Sweden is defined as a professional training program which means that students to a large extent are focused on practical aspects of the profession. In the paper, the intersections between students’ and the supervisor’s perceptions of and purpose of the thesis are explored. Two differing discourses were identified in the transcribed extracts of verbal interaction; academic code used mainly by the tutor and praxis code used by the students. The analysis focuses the meeting between these codes in relation to supervision and is inspired of the code theory of Basil Bernstein, where “codes” are used to describe regulative principles, realized through different possibilities of selection and combination (Atkinson, 1985). Language is also used as a means to understand social relationships, structures and processes. Noticeable is that within these codes the same expressions were used to great extent, but with different meanings and in different contexts.
