Several studies have reported unsatisfactory learning outcomes and negative perceptions of online language learning (e.g., Cavanaugh, 2001; Oliver, Kellogg, & Patel, 2012). The 2016 UVa STARTALK program has embarked on multifaceted research projects to seek possible solutions to these challenges. In this presentation, the presenter will present selected findings in the following order: 1) highlight the reinvented curriculum of the online course and effective pedagogy that instructors collaboratively implemented online, 2) analyze students’ perceptions of three ways of interaction and their reflections on learning experiences, and 3) reveal keys to successful design and implementation of future online language courses.
