It has been commonly believed that language learning strategy training would improve language learning and should be included in English instructions. However, not many of the studies in language learning strategy training have had conclusive results about its effects on language learning. According to researchers, these studies generally suffered various methodological problems. In Taiwan, although studies in language learning strategy have gained an increasing interest, rather few empirical studies have further explored the issue of strategy training. This study attempts to evaluate a semester-long English learning-strategy training course in terms of its effects in learners' learning achievement and learning attitudes. The participants of the study, 47 Taiwanese college students, were divided into the experimental group and the control group. The findings supported the assumptions that language-learning strategies are teachable and able to help foreign language learners' learning.
