Language development in children goes hand in hand with physical and cognitive development. Children learn their first language by imitation, but not always and not only by imitation. There seems to be some "innate capacities" that make children start to speak at the same time they do and in the way they do it. Adults learning a second language usually are controlled more by their motivation. But language input is important for both L1 and L2 acquisition. Though there are differences between CL1 and between CL2 and AL2, the way in which these learners acquire some of the grammatical morphemes is similar. This, together with some other evidence, shows that it is not only children who can acquire language. Adults can also acquire a language. But when adults acquire a language, they should also learn it. Some of the ways in which children acquire their language can be used as a model for L2 acquisition, even for Chinese students whose language is unrelated to English and whose culture is different. Learning the culture of the English-speaking countries will benefit the learning of the language. Like children, listening should also be well in advance of speaking in L2 acquisition. To train listening comprehension skills, Asher’s TPR approach proves more effective. TPR approach is at the moment limited to the beginning stage only. In order for students to gain all the five skills in a second language learning, namely, listening, speaking, reading, writing, and interpreting/translating, other methods should be used at the same time, or at later stages.展开更多

The students' learning of Indonesian for foreign is in so many aspects that it must be considered from both psychological aspects of students' language and cultural aspects. The research was carried out on foreign students' studying Indonesian language. The research method used action research. ODL model developed this concerning how the students are anxious in foreign language learning and language use in accordance with Indonesian culture. The model of ODL for teaching foreign Indonesian uses the Internet facilities such as email, Skype, VolP, Google Talk, circulating document with comments, chat, forum, CD, audio-video, stream media player, and e-learning system. Based on the results of this study which is that students study the model ODL for teaching Indonesian through socio-cultural approach and psychological aspects and students of Indonesian for foreign improve their ability to use the Indonesian language, students are able to converse fluently in Indonesian in accordance with Indonesian culture展开更多

How to use MOOCs to help universities rather than bother them to improve their education level and quality becomes an important issue. In China, many universities have explored the new modes and approaches for MOOC/SPOC-based teaching and learning. Especially, the China MOOC Association on Computing Education(CMOOC association), established in 2014, has done a set of successful practice and achieved fruitful experiences on MOOC courses development and computer education reform. Based on the practical experiences, a MOOC/SPOC based "1+M+N" multi-university collaborative teaching and learning mode is presented, which is adapted to the real situation of Chinese university education. In the paper, the practices and experiences of CMOOC association are introduced, the MOOC/SPOC based "1+M+N" multi-university collaborative teaching and learning mode and its approaches are described.

Besides, students' errors were also identified through observations by the researchers. As a result some of the mistakes made by students were found: lacking humor and variety in their interpreting, little vocabulary and variation in expression, etc.. Reasons were also analyzed which included that students were generally not familiar with some of the often-used sentence patterns for tour guide interpretation, and teachers are not using the suitable ways of teaching tour guide interpreting. To conclude, ways to solve these problems were recommended for readers' reference.展开更多

Under such circumstances, grammar-translation approach and audio-lingual approach are mainly applied in teaching. However, the application of task-based teaching approach in college English teaching makes a big difference. The students are no longer the passive recipients of information but the active participants. The advantages of this approach are well embodied in various aspects of college English teaching, including reading, writing, listening and speaking.展开更多

A nation wide heat of learning English arises in these decades, college students’ English competence becomes the most concern. This essay mainly discusses this concern from a communicative way by studying the theoretical base, the current situation of college English teaching and learning, thus to evoke the need for a new approach to language teaching, to show our students how the language system is used in normal communications and to enable them to cope with a varied range of situations in the target language.展开更多
