大学生的认知方式对其估算能力的影响

运用镶嵌图形测验(GEFT)和自编估算测试材料,考察了大学生的认知方式与其估算能力的关系.结果表明:①大学生的认知方式与估算能力密切相关,除整数题目外,在小数、分数及测验总分上场独立性的学生的估算成绩均显著好于场依存性学生.②场依存性大学生的数字题估算成绩显著好于文字题估算成绩而场独立性大学生的数字题和文字题估算成绩差异则不显著.③场独立性大学生的文字题估算成绩显著高于场依存性大学生的数字和文字题估算成绩.

The Relationship Between Undergraduates' Cognitive Style and Their Ability of Computational Estimation

Using GEFT and self-designed materials,this paper investigated the relationship between cogni- tive style and the ability of computational estimation using the students from a vocational college.The re- sults indicated that.There were a correlation between the cognitive style and computational estimation. The computational estimation achievement of those FI was significantly higher than that of those FD in the whole test,the decimal and fraction except the whole number.The computational estimation achievement of FD individuals in digit problem was significantly higher than in word problem,but the same results were not found in FI individuals.In addition,the computational estimation achievement of FI in word problems was significant higher than that of FD in digit and word problems.
