This has led to many controversies among teachers and researchers over the use of English in the classroom. However, it does not seem that there have not been any truly fruitful discussions on this issue up to now. One of the main reasons for promoting English-only classrooms is the belief that exclusive use of English in the classroom will motivate and improve students' English skills. Therefore, first, this study examinsd the background of second language (L2) use in the classroom as proposed by MEXT, while contending that first language (L1) plays a significant role in the L2 classroom. In addition, it considers not only the roles of L1 and L2, but also the effective use of both languages in the classroom. In particular, it emphasized that L2 teachers need to raise students' interest in language by means of language awareness, and to consider the balance of L1 and L2 within the classroom in order to develop students' L1 and L2 skills simultaneously. Finally, this paper proposes language planning in the classroom, paying particular attention to translanguaging (Williams, 1996), as a method of developing both L1 and L2 language skills., 論文 (Article)}, pages = {1--15}, title = {A study on the roles of L1 and L2 in foreign language classroom : language awareness, language planning, and translanguaging}, volume = {31}, year = {2014}, yomi = {イイダ, ツヨシ} }
