What is English-Medium Instruction

The influence from the developed countries has extended to most parts of Asia, especially Southeast Asia. This has given rise to the issues of multilingual and multicultural conflicts, especially in the post-COVID-19 outbreak. A multicultural society usually has many different ethnic or national cultures mingling freely, involving in social policies which support or encourage cultural practices, and together with this is the coexistence of multilingualism. Bilingualism or multilingualism is a challenging field that stems from diverse interdisciplinary interests and results from numerous variables that are closely related. From a more realistic view of multilingualism, language specialists can make learning languages in the classroom and in social environments a positive experience in which both or more languages are valued. All the issues related to the English-medium instruction for the tertiary level in a multilingual and multicultural context will be presented in the chapter.
