In the previous Chapters, the background of the study was introduced, the relevant up-to-date literature was reviewed, the research design and theoretical framework were detailed and justified, and the procedures of data collection and analyses were described and presented. The main findings in the previous Chapters were conceptualized in thematic components which shared the dialectic relationship. They were interrelated with one another, forming a training framework as a guidance for future implementation. Therefore, a new proposal for a holistic framework for in-service training for EFL teachers in the context of Vietnam was put forward for in-depth discussion in this final chapter. This chapter also provides specific implication for K–12 EFL teachers’ in-service training in Vietnam. In the general conclusion, the key points of the whole research project are summarized. The limitation of the study is also addressed. Finally, it addresses how the study can expand existing knowledge and contribute to new knowledge created in the field of ICT-related EFL teachers’ PD and training in such a context.
