dc.description.abstract | This thesis is designed to explore the factors affecting the success of Communicative Language
Teaching (CLT) which is currently implemented in private high schools in Vietnam with a case
study in the international schools of North America. There are various factors highlighted in
the research, including students, teachers, materials used, teaching and learning environment
and school curriculum. To do this, a qualitative method was used with the support of different
tools, including interviews, class observation, group discussion and informal dialogue. In
addition, the researcher is an insider of the international school which beneficially enhance the
validity of the research and directly find out what factors influence the success of CLT
implementation. Moreover, classroom observations were done by the author to directly collect
and note down necessary information for the research with the support of a communicative
language teaching observation scheme. Furthermore, it was found that the private school is
more successful in supporting students to be proficient English communicators than
Vietnamese public high schools. In the discussion, the author gathers the findings from
previous studies regarding the CLT in public schools in Vietnam to have some comparisons
and gives out explanations for the differences. Several suggestions are also recommended for
the application of CLT, which are based on the success of CLT in the international school. By
this means, the author aims to show the success of the international school and see whether this
model can apply in public high schools in Vietnam and to what extent. | vi |
