ASEAN charter article 34 states that “The working language of ASEAN shall be English”, this
is because AEC has used English as the official language to communicate (Nopporn, 2556).
However, Little (2011) argued that the current situation of the Thais’ English skills is below the
standard of English education. There are some evidences of Thai students performing poorly in the
English language when they are in comparison with ASEAN partners (TOEFL, 2010). There were
several factors that affecting the low quality of English language, one has been a lack of support in
teaching and learning approaches such as the study materials and environment that motivate the
learners (Van Patten and William, 2007). A study by Permvongsenee (2012) stated that Thai students
use English to communicate just in the English language class, after finishing class they preferred
to use Thai rather than the English language because they never really paid attention to the
lessons. On the other hand, it’s because the learners don’t really have a strong support to
encourage their learning and develop their skills.
