This document discusses demotivation in English language learning among Vietnamese students. It investigates the reasons for demotivation, called demotives, the degree to which different demotives influence students, and how students overcome demotivation. A study using recall essays from 100 university students found demotivation was significant and identified sources of demotives. Research shows motivation is key to second language acquisition, but many students in countries requiring English education fail to learn it and lose interest over time, becoming demotivated. This study addresses the extent of demotivation as a problem for Vietnamese students learning English as a foreign language, factors contributing to demotives, whether demotives differ in impact level, and how students overcome demotivation.
