Instruction of Korean as a foreign language (KFL) is making an unprecedented rapid growth both overseas and in Korea. Needless to say, this is due mainly to the near-miraculous development of the Korean economy, the marked increase in the overseas Korean population, and the firm commitment and sincere efforts of the Korean government and relevant Korean organizations to globalize Korean studies and the Korean language and culture. The learning of Korean has thus been greatly promoted as the Korean language is the foundation on which all areas of Korean studies are built: Korean is the means by which non-Koreans conduct cross-cultural communication with Koreans; and Korean is the basis through which overseas Koreans maintain their national heritage, identity and pride. The key to these vital needs is the effective teaching of KFL supplemented with superior textbooks and other teaching or learning aids.
