A Brief Glossary of Key Terms and Concepts in Sociocultural Theory and Second Language Learning

This glossary, originally composed in Spanish and now translated into English, compiles a list of essential Sociocultural Theory (SCT) concepts that are relevant to Second Language (L2) teaching and learning, applied linguistics, and research methodology. The terms compiled here define key SCT concepts with a focus on brevity (one paragraph definitions). This glossary is only intended as a point of departure to support and promote consistent research practices and applications within educational contexts. To conclude, we also include a basic protocol for integrating this glossary into research practices.
