Discussion: multiple approaches in CLIL: cognitive, affective and linguistic insights

This article is an afterword to the special issue on ‘Assessing CLIL: A multidisciplinary approach'. It provides a conceptual overview of the key approaches and issues in CLIL research addressed in the different articles. Apart from the focus on the comparison of CLIL and non-CLIL students' L2 proficiency in the Belgian context, some of the variables addressed are the focus on different L2s, the longitudinal approach, or the use of a solid corpus of learner language. The different approaches to SLA addressed in the issue (cognitive, attitudinal and linguistic) are also discussed.
