Effects of using content and language integrated learning instruction in english as a foreign language classes

Abstract

Content and Language Integrated Learning (CLIL) is an approach that is applied in many countries around the world, and it consists of integrating any subject with a foreign language in order to learn both at the same time. Research claims many positive effects of CLIL on students; therefore, the aim of this research synthesis is to explore the potential of CLIL instruction by analyzing the results of 17 studies that compared this methodology with traditional EFL programs in both primary and secondary schools. This analysis focused on the effects of CLIL on linguistic competence regarding the four skills, vocabulary and motivation. Findings showed that oral production, receptive vocabulary, and motivation are significantly higher on CLIL students. In addition, writing is also significantly higher on CLIL students, but few studies focused on this area of the language. Furthermore, CLIL also offers important benefits for receptive skills but only on secondary students. Finally, further research is suggested on this topic regarding productive vocabulary and writing around Europe, but around Latin America regarding the 4 skills. Moreover, there are many variables that might play an important role when applying CLIL and should be controlled.
