Exprgram: A Language Learning Interface for Mastering Pragmatic Competence

Mastering pragmatic competence, the ability to use language in a contextually appropriate way, is one of the most challenging parts of foreign language learning. Despite its importance, existing language learning systems often focus on linguistic components such as grammar, vocabulary, or pronunciation. Consequently, foreign language learners may generate grammatically flawless speech that is contextually inappropriate. With the diverse socio-cultural contexts captured in real-life settings, videos at scale can serve as a great material for learners to acquire pragmatic competence. We introduce Exprgram, a web-based video learning interface that assists learners to master pragmatic competence. With Exprgram, learners can raise their context-awareness, practice generating an alternative expression, and learn alternative expressions for the given context. Our user study with 12 advanced English learners shows potential in our learner-sourcing approach to collecting descriptive context annotations and diverse alternative expressions.
