The main purpose of this essay is to study how classroom interaction can take place in a class for Second Language Learners (SLL).1 I have applied a case study methodology on a linguistic method used by a Teacher in Swedish as Second Language working on a primary school situated in the Southern suburbs of Stockholm. The learning method is based on extensive reading of books which comprehend several learning techniques organized into a process that support the development of linguistic skills such as discussing in a group, writing, reading and thinking in a second language. The methodology applied is based on observations, on an interview with a Teacher in Swedish as Second Language and on a questionnaire answered by 11 students that participated on ?Boksamtal?.Based on a theoretical framework about socio cultural theories on learning and scaffolding,2 I attempt to integrate theory and practice to investigate how the Teacher succeed on applying effective methods for second language learning. Through the analyses of the data is also my intention to emphasize the advantages and disadvantages of such a method.
