In this empirical study, the aim is to investigate how and why teachers in five elementary classes in Sweden use the target language and first language respectively in the EFL classroom. In addition to investigating the teacher perspective, pupils are also asked how they perceive their English teacher’s choice of spoken language in the EFL classroom. The study has a theoretical base in Krashen’s (1982) Second Language Acquisition Theory, as well as previous research on teachers’ language use in the EFL classroom. The study revealed that the participating teachers use the target language mainly to instruct, and to encourage their pupils to produce English themselves. The study also showed that the first language is used to aid comprehension and to explain when the pupils do not seem to understand what is said in English. Furthermore, some of the participating teachers expressed a desire to use more target language in their teaching, while feeling obligated to speak Swedish to make sure all pupils understand. The results of the study also show that participating pupils find English in general to be both easy and fun, in one or several aspects, and that most of the pupils in the study appreciate their teacher using the target language during English lessons. Another conclusion that can be drawn is that more research is needed regarding how teachers’ linguistic choices actually affect pupils’ communicative proficiency in the English language. / <p>Engelska</p>

This systematic literature review examines the language use in the EFL classroom in lower secondary school. It aims to investigate how the target language, English, and local languages are used. Furthermore, teachers’ as well as students’ views on the language use in the classroom were investigated. This was done by compiling and comparing the findings of eight peer- reviewed research articles about the topic. The results show that language practices as well as views differ between teachers and their pupils. However, the general picture shows that, although English is the main language in the EFL classroom, there are contexts in which the pupil’s native language can be used beneficially.

In light of the 2010 recommendation of the American Council on the Teaching of Foreign Languages that teachers use the target language (TL) "as exclusively as possible," teachers face the necessity of promoting target language use and assessing how their language choices influence their students. The purpose of this study was to analyze teachers' perspectives and practices of whether to use students' first language or the target language. Data from over 100 foreign language teachers, predominantly those in the K-12 sector, were collected through a survey in order to measure how teachers manage the phenomenon of language choice. The findings were analyzed descriptively, categorically, and inferentially to find relationships among teachers in general, as well as within subgroups of participants. Findings indicate that teachers felt using the target language was more of a challenge for academic purposes because of their belief that they should be conducted in the TL. Academic tasks were also reported involving a greater quantity of speech functions, which made them more difficult to complete in the target language. Additional findings showed that teachers in general were most often influenced by student attitudes, motivation, and proficiency as well as their own attitudes, motivation, and proficiency. For certain subgroups, however, when teachers focused more on their own proficiency, motivation, training and experience they were more likely to reach 90% TL use or more. Furthermore, it was found that promoting the target language effectively equated with incorporating many strategies that supported TL goals. The most prevalent techniques found for promoting TL use were preparing for making input comprehensible, giving praise and recognition, and explaining its importance at the beginning of the year. Recommendations for increasing the ability of teachers to face the challenges of TL use are to simplify and increase the academic, social, and managerial purposes for which it can be used, prioritize and focus on the most influential factors of language choice (LC) within teachers' control, and form and promote a plan for TL use built upon a foundation of most effective techniques and practices for optimizing language choices.
