In Singapore's unique and complex linguistic environment, it is common to have Chinese-language learners from many different backgrounds in the same school classroom, which is why Singapore is nicknamed as a "language laboratory." In this paper, I hope to examine our linguistic environment and response strategies from different angles, including theories of second-language acquisition and Singapore's teaching methods and distinguishing features. This paper argues that Singapore's approach to teaching Chinese as a second language have to be highly diverse and specialized, in cohesion with Singapore's constantly evolving sociolinguistic landscape and Chinese-language teaching environment.
