Mandarin has become one of the popular languages to be learnt by non-native Mandarin learners, but
the learners always found that learning Mandarin is difficult. Hence, in recent years, Massive Open Online
Courses (MOOC) has become gradually popular in language learning as it makes learning become spontaneous,
ubiquitous and informal. In this research, a MOOC supportive application called Quizlet was implemented and
in the end of the study, a questionnaire in was delivered to students in a university in Kelantan. The research
findings show that non-native Mandarin learners demonstrated positive reactions towards the Quizlet
application tools applied in MOOC, such as Flashcards, Spell, Learn, Test and Scatter or Match. However, the
findings also indicate that there were certain tools such as text audio, picture, exercise and vocabulary, are
needed to be developed as part of Quizlet learning tools.
