基于建构主义理论和维果斯基的最近发展区理论,美国教育家布鲁纳、伍德以及麦瑟提出了支架理论。自该理论问世以来,受到了国内外学者以及专家的关注,也得到许多语言教师的青睐。关于该理论的研究也层出不穷。本文对该理论在大学英语写作教学中的应用进行了理性的分析和探讨。 Based on constructivist theory and Vygotsky’s theory of recent development zones, American educators Bruner, Wood, and Metzel presented the theory of scaffolding. Since the advent of this theory, it has received the attention of scholars and experts both at home and abroad, and has also been favored by many language teachers. Research on this theory is also emerging. This thesis makes a rational analysis and discussion on the application of this theory in college English writing teaching.
