Unfortunately, though, it seldom takes advantage of the new technologies and capabilities offered by the modern World Wide Web. In this article, we present an interactive online platform that provides users with learning activities for students of English as a foreign language. The platform focuses on using audiovisual multimedia content and a user experience (UX) centered approach to provide learners with an enhanced learning experience that aims at improving their knowledge level while at the same time increasing their engagement and motivation to participate in learning. To achieve this, the platform uses advanced techniques, such as interactive vocabulary and pronunciation assistance, mini-games, embedded media, voice recording, and more. In addition, the platform provides educators with analytics about user engagement and performance. In this study, more than 100 young students participated in a preliminary use of the aforementioned platform and provided feedback concerning their experience. Both the platform’s metrics and the user-provided feedback indicated increased engagement and a preference of the participants for interactive audiovisual multimedia-based learning activities.</span> </p>展开更多

Leamers had the opportunity, rare in foreign-language instruction, to discuss topics from their textbook in authentic native/non-native dyads. The interactions also allowed the seniors to fulfill an identified community needed by socializing in Spanish. Analyses of a post-service survey revealed that learners assessed the experience positively, because they spoke Spanish creatively. Seniors were described as cooperative and fun interlocutors, suggesting that age difference minimally affected the interactions. Direct observation revealed that learners managed to produce L2 Spanish output in connected speech for an extended period of time. Likewise, the seniors enjoyed a moment of socialization and first language use while sharing their views on the topics of discussion with the young visitors. Seniors＇ active participation likely encouraged learners to cope with sudden switches of topics that required negotiating for meaning and pushing the still limited interlanguages. A new service leaming study proposes to investigate the use of native/non-native dyads in Spanish in fulfilling a dual function： socialization and first language maintenance for the seniors at the center and language learning for the students.展开更多

Interaction plays a key role in second language classroom. Teacher questioning, as one of the teacher initiating activities, could facilitate students＇ language acquisition by asking questions and initiating responses from students. In this essay, two samples of teacher questions were looked into to find out the types, purposes and effectiveness of teacher questions. It was found that the experienced teacher was better at employing teacher questions for interaction than the student teacher. Both of them should improve the questions they asked in classroom. More effective teacher questioning should be introduced according to specific language learning environment by referring to the cognitive level of the students and more opportunities and motivation should be provided for students＇ response.展开更多

Based on Vygotskian approaches, this paper looks at the causes of interlanguage fossilization, including social identity, learners' motivation, the influence of one's mother tongue and learning styles. By vividly incorporating my own language learning experience, this paper intends to explain how theory can be applied to practice; thereby attempting to shed light on second language learning and teaching. In conclusion, this paper suggests that teachers should get to know their students by paying attention to the most influential factors and encourage interpersonal interaction.展开更多
