Book Review of Lee (2025) Social Media and Language Learning. Using TikTok and Instagram.

Yeong-Ju Lee’s “Social Media and Language Learning Using TikTok and Instagram” investigates how informal language learning takes place within mobile social media spaces, focusing on multimodal content and learner agency. Using comparative content analysis of Instagram and TikTok language-learning posts and case studies of international students, Lee demonstrates that both platforms foster creative, autonomous, and multimodal language development, while offering distinct affordances for pronunciation, vocabulary, and grammar learning. The book translates empirical findings into ready-to-use classroom strategies, bridging formal and informal learning, and provides directions for further research in mobile-assisted and multimodal language education.
