【摘要】：本研究借鉴辩证认知理论的批判性话语分析视角,使用批量国内高校英语课堂教学的多模态语料,通过量化提取和二元回归分析手段来揭示教师支架对话中语伴手势、话轮类型和支架策略的互动特征以及这三者协同对支架效果的影响。结果发现:支架类话轮中的手势种类及频次(尤其是指示类和语用类手势)最多且成功率高;支架策略中的“提问类”和“解释类”策略使用频率较高,其中前者与手势协同较能促进支架成功;后者则有消极作用。二元回归分析还发现,手势类型、话轮类型和支架策略三者均对支架效果有显著影响。其中“支架类话轮”中的手势使用频率对支架效果有显著积极影响。“提问策略”使用也会影响改善支架效果。而“操作类手势”和“解释策略”则对支架效果有显著消极影响。
[Abstract]:Using the critical discourse analysis perspective of dialectical cognitive theory for reference, this study uses the multi-modal corpus of English classroom teaching in domestic colleges and universities to reveal the partner gestures in teacher-supported dialogue by means of quantitative extraction and binary regression analysis. The interactive characteristics of turn type and stent strategy and the influence of these three kinds of cooperation on the effect of scaffolds. The results showed that the type and frequency of gestures (especially the deixis and pragmatic gestures) were the most and the success rate was high in the stents. The use frequency of "question class" and "explanation class" strategy in stent strategy is higher, in which the former can promote the success of stents in coordination with gesture, while the latter has a negative effect on the use of "question class" and "explanation class" strategy. The binary regression analysis also found that gesture type, turn type and stents strategy all had significant influence on the effect of stents. Among them, the frequency of gesture usage in Stent-like turn has a significant positive effect on the effect of Stent. The use of "question strategy" will also affect the effectiveness of the stent. On the other hand, "manipulation gesture" and "explanation strategy" had a significant negative effect on the stent effect.
