The effects of CLIL on L1, L2, and subject contenta quantitative and qualitative investigation

Resumen

The present longitudinal study aims at evaluating CLIL implementation in Primary and Secondary Education centres situated in the province of Jaén, from a qualitative and a quantitative point of view. Firstly, stakeholders’ perspectives on bilingual programmes have been collected by means of questionnaires and semi-structured interviews, which has allowed us to develop a SWOT analysis of the Strategic Plan for the development of languages in Andalusia. In the quantitative side of the project, the impact that CLIL exerts on L1, L2 and subject content learning has been evaluated, analysing if statistically significant differences arise when comparing the results of CLIL and non-CLIL students. In the same vein, we have analysed if such effects pervade six months after the programme has been discontinued, when the pupils are in the first grade of Baccalaureate.
