数学学业不良儿童的估算能力与估算情感因素的关系

通过运用自编材料对某小学六年级20名数学学业不良儿童和20名学优儿童的测试，发现：1）数学学业不良儿童在估算类型、数字类型及四则运算上的表现显著低于学优儿童；2）数学学业不良儿童和学优儿童在自信心、情感认同及总分上均存在显著差异，数学学业不良儿童还在情感认同和有用性认同及总的情感得分上存在性别差异；3）就所有学生来说，自信心和情感认同对估算能力有预测作用，但数学学业不良儿童的估算表现主要受情感认同的影响，而学优儿童主要受自信心的影响．

THE RELATIONSHIP BETWEEN CHILDREN'S COMPUTATIONAL ESTIMATION COMPETENCE AND THEIR EMOTIONAL FACTORS WITH MATHEMATICAL LD

Using self-developed tools,this paper investigated the relationship between mathematically learning disability(LD)students' computational estimation competence and their emotional factors influencing computational estimation competence.20 mathematically learning disability students and 20 mathematically gifted students participated in this study.The results showed that:1)there were significant differences in types of computational estimation,the types of numbers and operations in the items between the gifted and the LDs.And the performances of the LDs were significantly lower than that of the gifted.2)There were significant differences in self-confidence,emotional identity and total per formances between the gifted and the LDs.In addition,significant gender differences were found at the total emotional performances, emotional identity and utility identity in LDs.3)To all students,computational estimation competence were significantly predicted by self-confidence and emotional identity,especially by self-confidence.The performances of the LDs were affected by emotional identity,but that of the gifted was affected by self-confidence.
