The Department of Linguistics and Modern Language Studies (LML) of The Education University of Hong Kong (EdUHK) organised the XXth International Computer Assisted Language Learning (CALL) Research Conference from 10 to 12 July 2019. Speaking at the opening ceremony, Professor John Lee Chi-kin, Vice President (Academic) at EdUHK, emphasised EdUHK’s important role in promoting educational technology, language education, and computer-assisted language learning, and its impact on the well-being of Hong Kong society and beyond. More than 120 abstracts were accepted, and over 140 participants attended the conference, representing over 25 countries and regions, including Australia, Canada, France, Japan, mainland China, New Zealand, the Philippines, Russia, Spain, Thailand and the United States.

The Conference covered a broad variety of social topics, including diversity and inclusion, migration and integration, critical consciousness and critical pedagogy, intercultural and transcultural dialogue, minority languages, and other social CALL-related topics. These sub-themes show clearly the social responsibilities of the CALL field, which not only benefit the university and school settings, but also address the needs and concerns of numerous communities in broader society. The Conference was honoured to invite the following distinguished keynote speakers:

• Professor Antonie Alm (Associate Editor of the CALL Journal)
• Professor Mirjam Hauck (President of EuroCALL)
• Professor Gu Yueguo (President of ChinaCALL)

CALL 2019 addressed the social dimensions of CALL, more specifically the social challenges and responsibilities in conducting related research. By encouraging the participants to present their current or recent research, this year’s event was tremendously beneficial to the academic field of Social CALL by providing a platform for academics from around the world to exchange ideas and thoughts. The three-day conference provided a CALL "banquet", where the participants were highly motivated and inspired by the passion and creativity of the CALL scholars and researchers. The conference helped form a warm CALL community for both very experienced and new CALL researchers.
