The main aim of this article is to evaluate the outcomes presented in the previous articles in relation to similar projects and studies conducted in monolingual contexts in other parts of Europe as well as Latin America, where bilingual education and CLIL are increasingly being embraced in the official curricula. The effects of CLIL on L1, L2 and…

In an era of globalization, multilingualism is no longer the exception but the rule. To fully promote the communicative and functional development of multilingual learners, different educational programs at school have been implemented in the past few years. The study presented here is a contribution in this direction, by investigating the…

As academic language skills develop, young learners are able to rise to the challenge of increasingly complex communication in increasingly formal settings (Snow, 2014; Uccelli et al., 2015). Studies suggest that CLIL contexts may favour the development of academic language skills (Dalton-Puffer, 2007; Nikula, 2007; Marsh, 2008; Pasqual Peña,…

Although the core element in CLIL and immersion programmes is the integration of content and language, it is challenging to achieve a balance between the two to meet the dual-objective of CLIL. Research on the beliefs teachers have about CLIL and the way they understand the role of content and language in their classes is crucial to achieve that…

The increase in global migration and the prioritization of English as an international language have resulted in science learning environments that include students whose primary language differs from the language of instruction. This worldwide phenomenon is not limited to geographical regions but occurs where diverse populations representing…

This article focuses on the 'native speaker effects' (Doerr, N. M., ed. 2009. "The Native Speaker Concept: Ethnographic Investigations of Native Speaker Effects." Berlin: Mouton de Gruyter) pertaining to the construction of eliteness in Spanish-English CLIL-type bilingual programmes in the autonomous community of Castilla-La Mancha…

Although CLIL (content and language integrated learning) programmes are now globally expanding, the number of studies that have examined their impact on both multiple language learning (students' L1, L2 and English as a foreign language) and content learning are scarce. This study investigates the effects of a CLIL programme implemented in a rural…

The use of communication strategies (CSs) in oral and written second language (L2) production has been widely investigated (e.g. Muñoz, 2007). As for content and language integrated learning (CLIL) settings, learners seem to resort to the first language (L1) less often than in traditional foreign language instruction (e.g. Celaya & Ruiz de…

This paper investigates students' performance in content-subjects in the framework of CLIL programmes in Spain. So far, CLIL research has focused primarily on language attainment in the L2 and the L1, but students' achievements as regards content-subjects have been largely ignored. Competence in Science in the L1 is analysed by comparing pupils…

Translanguaging practices come into play in social interactions between bilinguals when they are making use of all their shared linguistic resources and blending their languages in natural ways. Stemming from these practices is translanguaging pedagogy, which is designed so that students in school-based additive bilingual programs can benefit from…

This study investigates the role of biological age and L2 exposure on the achievement of two groups of Catalan-Spanish intermediate learners of English in secondary school (Group A, Formal Instruction (FI), N = 50; Group B, FI + CLIL, N = 50) regarding receptive and productive L2 skills as well as grammatical knowledge. Learners were matched for…

We describe research results and lessons learned from a laboratory/classroom collaboration with a school system offering both traditional English-only education and a dual-language track (Spanish/English). Through this collaboration, we addressed basic research questions informing malleable factors that impact cognitive development. In a…

In Content and Language Integrated Learning (CLIL), the design of a language policy at school level is not only bound up with the number of languages used for learning and the number of hours devoted to teaching those languages, but also with the fact that language becomes specialised in relation to the subject, which impacts on the methodology…

Content and language integrated learning (CLIL) programmes are mushrooming in many different contexts. However, research has mainly focused on their impact on foreign language learning and to a lesser extent on L1 development, whereas the number of studies undertaken in multilingual contexts in which more than two languages coexist is negligible.…

Immersion programs face a variety of challenges that are common to the field, such as lack of materials appropriate for students' language abilities, assessment, teacher recruitment and retention, balancing content and language, and relevant, high quality professional development for teachers. However, within specific micro-contexts, other issues…
