摘要:AbstractThe advent of bilingual programs to tertiary education has meant a noticeable change and introduced Content and Language Integrated Learning (CLIL) approach into Spanish universities. Learning specific contents through the medium of English requires extra language support to access new knowledge; hence the relevance of a specific corpus which encases the key vocabulary and phrases of the content language of a subject or even of a university degree. This study suggests equating the language of learning (Coyle et al., 2010) to the key words found by using the keywords tool in Wordsmith (Scott, 2008) and provides an analysis of the keywords in TEC, a corpus specialized in telecommunication English. Consequently, this research reports on the bilingual degree in Telecommunication at the UPCT within the framework of CLIL and why the specialized corpus brings a considerable advantage to that situation.
