The document discusses the history and evolution of CALL (computer-assisted language learning) materials for teaching English as a foreign language. It notes that while many CALL materials have been produced in the last 10-15 years, CALL has not been fully integrated into mainstream education. It also discusses early criticisms of the low quality of software produced by inexperienced language teachers in the 1980s. However, the pioneering efforts of language teachers were still important for developing the field of CALL. More recently, the focus has shifted from debates around teacher involvement in materials development to improving CALL technologies.
