Effect of language learning strategies on vocabulary development in CLIL

Abstract

This study focuses on language learning strategy use examined in the context of Content and Language Integrated Learning (CLIL) with a specific focus on productive vocabulary development in a school year time frame. The research took place in the Czech Republic, a sample comprised of 286 pupils ranging from 11 to 14 years of age, a total of 12 classes spread over three schools. Half of the experimental group had one year of CLIL experience prior to the study. The content subjects in the experimental classes were History and Civics; the language of instruction was English. The study aimed at finding out what is the connection between language learning strategies and vocabulary acquisition in CLIL classes. Standardized Laufer & Nation’s vocabulary levels tests and Oxford’s Strategy Inventory for Language Learning served as data collection instruments. Variables taken into consideration were CLIL experience, gender, content subject and teacher. The previous year of CLIL and the teacher turned out to be significant. Concerning the questionnaires, five strategies showed a positive influence on the growth of productive vocabulary. Surprisingly enough, five strategies negatively impacted vocabulary. Strategies using a task-based methodology proved superior to purely vocabulary-based strategies.
