Formulating a Theory of Second Language Learning

This article is intended to establish a framework for the formulation of a comprehensive theory of second language learning in which theories of first and second language learning may combine to form a unified theory. It proceeds through a critical assessment of currently one of the foremost theories, the monitor model (Krashen, 1982). Each of Krashen's five hypotheses is considered, and counteropinions, fortified with the results of research, are presented. The article concludes with a call for a more comprehensive theory that accounts for the diverse ways in which people develop their ability to use a second language.
