چکیده (انگلیسی):

The purpose of the study is to provide a guideline for the pedagogical approaches to teach Thai
students the grammar of the Chinese adverbs “zài” and “yòu”. Questionnaire results revealed
that the reasons for the misuse of “zài” and “yòu” by Thai university students can be classified
into three causes: (1) “zài” and “yòu” suggest repeatedness and both of them can be literally
translated into the Thai /Ik/,(2) the complicated semantic characteristics of “zài” and “yòu”
themselves and (3) the situation in the process of “zài” and “yòu” acquisition being not
completed. In terms of pedagogical approaches, this study presents an appropriate sequence for
the learning of the adverbs “zài” and “yòu” in Mandarin Chinese according to the frequency of
occurrence and the frequency of error. Furthermore, the study suggests that teachers should first
teach the grammar points that are used more frequently and have more straightforward semantics
familiar to most students. Those used infrequently and likely to cause errors should be taught later.
