摘要：Social networks play indispensable roles in fostering second language learning by providing a wide array of authentic materials. The purpose of this review is to consider social networks, such as Facebook, Electronic mail, Computer media which are proven to be effective to increase students’ learning English out of the classes. Social networks facilitate students’ interaction to share their ideas, and provide an opportunity for learners to experience online tools to foster their learning skills. It was realized that these online tools (e.g. Facebook, Email, and Computer media) can be used to improve students’ language skills especially writing skill. Internet tools help the second language learners to accelerate their learning by being up-to-date and self-directed. In this paper, the literatures were reviewed to find positive aspects of using Facebook to improve second language learning. The researchers also pointed out that second language is learned incidentally and directly from second language speakers of different culture via Emails. Students can use e-mail to communicate with their teachers and with second language speakers or native speakers. Computer media are also useful means to guide those learners who are passively focused on English learning. The review would conclude that social interaction via social networks is a kind of stimulus for learners to communicate with others.
