摘　　要：以32名初中二年级学生为被试,以Tobii 120眼动仪为工具,采用2×2×2的三因素混合实验设计,研究题目难度、冗余信息和数学成绩对代数应用题解题过程的影响。结果发现:题目难度和冗余信息对不同成绩学生的解题正确率、出入关键信息区域次数影响显著。题目难度、冗余信息与题目的相关性是影响学生解题的主要因素。Thirty-two middle school students in grade two were observed in the study.2×2×2 mixed design with the Tobbi120eye tracker was used to analyze the influence of the difficulty and redundancy and score in solving algebra word problem.The results showed that the difficulty and redundancy information affected significantly the right rate of solving problem,the frequency of coming in and going out of the key information area.Thus the difficulty and the relevance of redundancy information and problem are main factor in problem solving.

关 键 词：题目难度 冗余信息 代数应用题
