During this COVID-19 pandemic, no one can deny the value of online communication. It has saved our lives by preventing us from going outdoors and becoming infected, while also facilitating achievement of various personal and professional goals. Online communication can also assist us with our academic goals, whether it is used to communicate with supervisors or with people from other lingua-cultural backgrounds to practice the language. This form of communication is emphasized in the Common European Framework of Reference for Languages (CEFR) framework, which is one of the most significant guidelines for language teaching and learning throughout the world. The present research has two aims: first, to determine the extent to which CEFR-based online intercultural communication can improve Thai students’ communicative language competence, and second, to investigate Thai students’ attitudes toward CEFR-based online intercultural communication and international volunteers. The results received from 15 fifth-year dual B.A. (Chinese) and B.CM. (Traditional Chinese Medicine) students and international volunteers using various research instruments revealed that Thai students could increase their communicative language competence after participating in CEFR-based intercultural communication activities. This encompassed linguistic, sociolinguistic, and pragmatic abilities that correspond to the CEFR (2001) scales. In terms of attitudes, the study indicated that, because they were more confident in their communicative language ability, they had a positive attitude toward the CEFR-based online intercultural communication activities and their international volunteers. Finally, further research on this topic should include a proper design of online communication activities as well as methods for assessing students’ competency both before and after participation.

Currently, the role of English language has changed from being a language used among native English speakers (NESs) to being a language spoken by people of various backgrounds or known as English as a lingua franca (ELF). This phenomenon has affected different aspects of global English usage and users across the world. However, in Thailand, this issue does not seem to be taken into account with regard to English language teaching (ELT) and learning practices as different ELT stakeholders continue to conform to traditional teaching methods related to NESs. This action is reflected in an English language ideology called ‘native speakerism’ which has long been entrenched in Thai society. It has repeatedly caused different problems for both Thai teachers and students of English language until the present day. This review article aims to demonstrate the impacts of the native speakerism ideology on Thai teachers and students of English language in the period of English as a global lingua franca. The article begins with an explanation of how the changes of role and status of English challenge traditional perspectives of English language and how the ELT industry around the world, including in Thailand, should adapt to such changes. Then, the article gives brief conceptualizations of native speakerism and its effects on English teachers and students. Finally, it moves on to discuss the native speakerism ideology in Thailand and reports different negative effects of native speakerism on Thai teachers and students of English language.
