初中生的数学估计能力及其与元认知监控的关系

抽取济南市四所中学初一至初三年级547名学生为被试,采用自行设计的数学估计任务和元认知状态问卷(SMI),考察了初中生数学估计能力的现状及其与元认知监控的关系。结果表明:初中生的估计能力总体较差,未显示出稳定的性别差异。元认知监控的四个维度与数学估计表现均存在显著的正相关。从元认知监控对估计成绩的回归分析来看,自我意识可以显著正向预测估计整体表现。其中,计划可以正向预测估数和估算成绩,自我意识可以正向预测估测和估算成绩。文章特别讨论了数学估计与元认知加工之间的具体联系。

The Junior Middle School Students' Mathematical Estimation Performance and its Relationship with Their Metacognitive Ability

This research aimed to explore junior middle school students'mathematical estimation performance and its rela tionship with their metacognitive ability by self designed estimation tasks and State Metacognitive Inventory (SMI).547 grade one to three students randomly sampling from four secondary schools in Ji Nan City participated this research.The results showed that the junior middle school students'mathematical estimation ability was generally low and didn't reflect a stable gender difference.There was a strong positive correlation between estimation performance and metacognitive ability.Among the four factors of metacognition,self consciousness had significantly positive correlations with measure ment estimation and computational estimation.On the whole,self consciousness had a significant predictable effect on mathematical estimation,especially on measurement estimation and computational estimation.In addition,planning also had strong correlations with numerical estimation and computational estimation.Some of theoretical links between individ ual's mathematical estimation and metacognitive processing were deeply discussed.
