The result revealed that 1 From the cultural point of view, the tension between Tayal culture's "speech-based representation system" and Chinese culture's "character-based representation system" cause Tayal students difficulties carry out the transformation of representations. 2 Tension formed between Tayal students'"wholeness and conferring of meaning" thinking framework, and "partialness" presented in teaching material and teaching activities, is unfavorable for their understanding of mathematical concepts. 3 Tension is formed between Tayal culture's "open ended discussion" style and "close ended discussion" style in mathematics class, which lowered the opportunity for Tayal students to communicate mathematical knowledge.

研究结果发现：从文化的角度来看，泰雅文化的「言说表徵系统」与汉文化的「文字表徵系统」之间的张力，导致泰雅学生不易进行数学表徵的转换；泰雅学生「整体观及意义赋予」的思考方式与教材或教学方式所呈现的「部分观」所形成的张力，不利於泰雅学生理解数学概念；泰雅文化的「开放式对谈模式」与数学教室的「封闭式对谈模式」所形成的张力，减低了泰雅学生沟通数学知识的机会。

本文认为，胡塞尔的科学批判虽具有重要启发意义，但从科学和科学哲学的角度来看，他的批评在某些方面是不恰当的：①实证主义科学观固然不是健全的科学观，但现代科学自身却不是意义、价值等形而上学的领域；②尽管数学化的自然并不是自然本身，但数学化却是现代科学最有效、最可靠的方法；③胡塞尔反对任何实在论的自然观，但这种自然观是现代科学世界观的基础。
