This chapter reveals the overview of Computer-Assisted Language Learning (CALL) in foreign language learning; the overview of mobile technology in foreign language learning; the overview of Mobile-Assisted Language Learning (MALL); the overview of web-based language learning; Facebook applications in global education; social media applications in foreign language learning; and the significance of social media in foreign language learning. Through CALL, MALL, and social media applications, teachers and language learners can go online to read or listen to the learning material about different areas of interest, and can write or speak about what they have discovered, telling others in the foreign language class or other classes elsewhere in the world. Technology tools enable teachers to differentiate instruction and adapt classroom activities, thus enhancing the foreign language learning experience in global education.
