The prevalence of digital technologies, augmented by the emergence of generative AI, expands opportunities for language learning and use, empowers new modes of learning, and blurs the boundaries of in-class and out-of-class language learning. The language education community is challenged to reconceptualize the paradigm of language learning and utilize the affordances of technologies to synergize in-class and out-of-class language learning. To achieve this, in-depth understanding of in-class learning and out-of-class digital experiences in relation to one another is needed to inform curriculum and pedagogy conceptualization and implementation. With this aim in mind, we put forth a research agenda around six research themes. We hope that this Thinking Allowed piece can stimulate and guide systematic research efforts towards unleashing the potential of technologies to synergize in-class and out-of-class language learning and create holistic and empowering learning experiences for language learners.
