A Critical Review of Motivation in Second Language Acquisition Research

As one of the major factors affecting second language learners＇ success to their acquisition achievement, motivation has been examined in a wide variety of research papers. It is thus instructive to conduct a critical review of both theoretical and empirical developments in SLA research from over the last few decades. This approach will provide a broad, and integrated perspective onto the current understanding of the complex topic of motivation. Such an undertaking is valuable for teachers, and researchers alike, in developing useful teaching methods, and finding future avenues of SLA motivation research respectively.The following paper provides an overview of recent theoretical and empirical findings, examines some of the problems and contradictions found in current SLA research, and gives an initial departure point for future directions of research in the area of motivation. The paper concludes with a discussion of some of the implications for teachers, and possible classroom strategies that are drawn from the current body of motivation research.     

Making Non-English Majors "on the Move"

Researches have proved that adults can develop language acquisition device, too.
