It maximizes students＇ speaking time in a specified-time period. Group discussions have a strong positive effect on the atmosphere in the classroom and the behaviors of the students as they can get more ideas from their friends, and sometimes students don＇t even understand the topic for discussion but by interacting with others they can understand the topic. Particularly it is a good warm-up in conversational classes. The most important reason for using group discussions before speaking tasks is to reduce students＇ nervousness of making mistakes. And this encourages students to be more active in speaking class.展开更多

Current clinical guidelines for low-back pain recommend acupuncture for CLBP. However, there are very few high-quality acupuncture studies on CLBP in older adults. Clinical acupuncture experts in the American Traditional Chinese Medicine Association(ATCMA) were interested in the recent grant on CLBP research announced by the National Center for Complementary and Integrative Health. The ATCMA experts held an online discussion on the subject of real-world acupuncture treatments for CLBP in older adults. Seven participants, each with more than 20 years of acupuncture practice, discussed their own unique clinical experience while another participant talked about the potential mechanism of acupuncture in pain management. As a result of the discussion, a picture of a similar treatment strategy emerged across the participants for CLBP in older adults. This discussion shows that acupuncture may have complicated mechanisms in pain management, yet it is effective for the treatment of chronic pain involving maladaptive neuroplasticity;therefore, it should be effective for CLBP in older adults.展开更多

In general, participants need to reinforce their opinions and influence other participants. In this context, it is important to know how allies and opponents are positioned, in order to understand the discussion dynamics and plan adequate actions. This paper suggests the use of social network visualizations to explicit oppositions and alliances in order to support the understanding and following of political discussions. A system which supports these visualizations was built. An experiment performed to test the proposed visualizations showed to which extent they can be more efficient in identifying information about clashes and alliances than an online discussion system can.展开更多

The data used in the study consisted of the multicultural discussions in the corpus of English as a lingua franca in academic settings （ELFA）. The approach of conversation analysis （CA） was used together with corpus techniques with the aim to provide quantitative support to function categorizations which were drawn from qualitative analysis. Results of the study not only demonstrated the multi-functionality of you know and I mean but also suggested that these two discourse markers played specific functions in academic seminar discussions under ELF contexts. In the context of cross-cultural and academic communication where problematic terms may occur, we found that you know was mainly used to achieve clarity, while I mean was primarily used to correct previous statements and dysfluencies. The findings of this study will help ELF speakers communicate more effectively in academic interactions by recognizing the functions of discourse markers and using them properly.展开更多

The present study was designed to compare the written work of two groups of Chinese students, in order to identify the differences in writing outcomes achieved with different teaching methods: conducting group discussions with the Experimental Group (EG) and teacher-dominance with the Control Group (CG). By comparing the two groups' written products and analyzing the sample writings and questionnaire results, the study suggests that group discussion facilitates students' writing better than traditional classes, in terms of content, readership and thinking patterns.
