The use of the students' first language (L1) in the foreign language class (FL) is a common but controversial issue that has received little attention. This might be more relevant in the case of Content and Language Integrated Learning (CLIL), since, under CLIL approaches, students need to acquire content through an FL that they have not mastered…

For high school science teachers working with students who are in the beginning stages of English learning, it can be difficult to engage English learner (EL) students in using language that is accessible to understand complex scientific concepts. Improving EL students' access to science education is an important component of diversifying…

This study investigated primary students' perceptions of Content and Language Integrated Learning (CLIL) Natural Science and Social Sciences and variations in perceptions by individual and social factors. The sample comprised 524 Spanish-speaking students aged 9-13 years from bilingual Spanish-English schools in Andalusia (Spain). The study…

Reading and writing translate to centuries of shared knowledge and can be expanded upon with the ability to acquire multiple tongues. In response to today's most widely spoken languages, Chinese/English and Spanish/English dual language immersion programs continue to grow across the United States. Unfortunately, the lack of uniformity in the…

The provision of CLIL teachers in Spain has outpaced the growth of the so-called bilingual programs, as there are no specific training requirements for CLIL teachers who are either content or language specialists. So, CLIL teachers have a preexistent teacher identity that could influence their pedagogical choices. This study examines how teachers…

However influential the interdependence hypothesis has become in bilingual research, it still lacks full empirical support. This longitudinal study explores the parallels in the biliteracy development (L1 Spanish and L2 English) of 20 students in a European immersion programme (i.e. CLIL) over a two-year period. A bilingual learner corpus of…

We report on the use of bilingual constructed response science assessments in the context of a research and development partnership with secondary school science teachers. Our project provided a series of workshops for teachers where they explored students' emergent reform-oriented science meaning-making in our project-designed assessments. We…

This volume represents the first collection of empirical studies focusing on peer interaction for L2 learning. These studies aim to unveil the impact of mediating variables such as task type, mode of interaction, and social relationships on learners' interactional behaviors and language development in this unique and pedagogically powerful…
