Motivation?

以下是一個教英文寫作的老師的告白

Teaching English as a Foreign Language (EFL) writing is a headache for many teachers; they spend considerable time correcting their students’ compositions only to find their corrections and comments ignored. Despite teachers’ hard work, many students’ written English remains non-idiomatic, poorly organized, insufficiently developed, grammatically awkward, devoid of sentence structure variety, and weak in vocabulary usage. One important reason for all this is that learners have not been helped to become motivated, involved in their own learning, or self-sufficient. The fact is, students will not devote their efforts to learning a foreign language if they do not have a need or desire to learn it. However, when students are duly motivated, they will become involved in learning a foreign language and will learn it autonomously.

最後一段提到, 學生要有motivation(動機)學英文, 就必須是有need (需要) or desire (需求), 請大家幫我動動腦, 如何提高學生學習的motivation?
