ADAICLE – A CLIL learner corpus
A corpus of written texts produced by Primary and Secondary Education students in CLIL programmes across different school subjects .
The ADAICLE corpus has been developed by a multidisciplinary team of researchers at Universidad Internacional de La Rioja (UNIR), including members of the ENTELEARN Research Group. Compiled between 2024 and 2025, ADAICLE provides a valuable resource for the study of language learning, academic discourse, and bilingual education in CLIL contexts across Spain.
About ADAICLE
ADAICLE comprises 2,319 written texts produced by 504 students in Primary and Secondary Education CLIL programmes in Cantabria, Spain. The handwritten texts were collected during 2022-2023 by members of the ADAICLE research team as part of the ENEBE project (Evaluación Nacional de la Enseñanza Bilingüe en España; Vinuesa et al., 2024). The texts were produced in Natural Science, Social Science, Technology, and History, all taught through English, and were subsequently digitised and compiled into the ADAICLE corpus.
The corpus consists of two sub-corpora: Primary Education (1,632 texts) and Secondary Education (687 texts). Overall, ADAICLE contains more than 81,000 word tokens and 4,979 word types, making it a unique resource for investigating language learning and academic discourse in bilingual educational settings.
Funding and project team
ADAICLE was developed as part of the research project Análisis del Uso de las Alfabetizaciones Disciplinares Plurilingües en Inglés a través del Análisis de Corpus de Textos Escritos por Estudiantes de Educación Primaria y Secundaria en España (ADAICLE) PP-2024-10. The project was funded by the Universidad Internacional de La Rioja (UNIR) through its 2024–2026 Internal Research Projects Funding Programme.

Research based on ADAICLE
ADAICLE provides a rich resource for investigating language learning and academic literacy in CLIL contexts. The corpus enables researchers to explore lexico-grammatical complexity, discourse organization, and the development of academic language across educational levels. It also supports the analysis of learners’ interlanguage, including recurrent grammatical, lexical, and spelling errors, as well as translanguaging practices and discipline-specific language use.
