About this book
Informal Digital Learning of English (IDLE), defined as self-directed, independent, and autonomous English learning through digital technologies beyond the classroom (Lee & Dressman, 2018), has emerged as one of the most dynamic and consequential developments in language learning worldwide. As noted in Lee (2021), IDLE encompasses both receptive and productive forms of digital engagement, ranging from the consumption of online video, digital gaming, and social media to online collaboration, fanfiction writing, livestream interaction, and participation in virtual communities. It further foregrounds the complementary roles of form-focused (e.g., grammar, vocabulary, and sentence structure) and meaning-focused (e.g., comprehension and communication) learning activities in digital environments (Zou et al., 2025).
In recent years, Generative Artificial Intelligence (GenAI), powered by large language models (LLMs), has introduced unprecedented opportunities and challenges for language learning and teaching (Barrot, 2023). Tools such as ChatGPT and DeepSeek are capable of processing complex linguistic patterns and generating contextually appropriate, prompt-responsive outputs. These technologies offer increasingly sophisticated forms of personalization and adaptability, supporting activities such as idea generation, feedback provision, multimodal content creation, interactive dialogue, customized learning pathways, and simulated roles (e.g., examiner or conversational partner) (Kohnke et al., 2023). As a result, GenAI is rapidly transforming how learners engage with English across digital environments, reshaping language learning both within and beyond formal educational contexts. The emergence of GenAI-mediated IDLE thus represents a critical development within contemporary language learning ecologies.
This edited volume brings together cutting-edge research examining how GenAI-mediated IDLE is reshaping learners’ linguistic development, as well as their identities, motivation, emotions, cognition, curiosity, critical literacies, and autonomy. It also considers the implications of these developments for teachers, institutions, and policymakers.
Aligned with the aims of the New Language Learning and Teaching Environments series and in particular its emphasis on learner-centred pedagogies, out-of-class learning, and the impact of technology, this volume positions GenAI-IDLE as both a sociocultural phenomenon and an emerging pedagogical frontier.
Recent research indicates that (GenAI-)IDLE can enhance vocabulary, grammar, speaking, reading, listening, confidence, enjoyment, and intercultural competence (Pan et al., 2025; Schurz & Sundqvist, 2025). It also expands learner agency, increases exposure to multimodal and authentic input, and connects learners to global networks. Informal digital spaces are becoming increasingly significant as formal education systems continue to evolve in response to digitalisation, AI integration, and the expansion of hybrid learning environments.
However, despite its considerable potential, research consistently highlights limited institutional preparedness, insufficient teacher training, curricular misalignment, and persistent tensions between autonomous informal engagement and assessment-driven educational systems (Toffoli & Sockett, 2015; Lee & Drajati, 2019b). In addition, the growing role of algorithmically mediated learning raises critical questions about control, agency, and epistemic transparency.
This volume therefore addresses a set of urgent questions:
Through theoretically grounded, contextually rich, and practice-oriented chapters, this volume offers a comprehensive synthesis of global research on GenAI-mediated IDLE, alongside concrete pedagogical applications and directions for future research and policy.
