Pursuing the line of the difference models in IRT (Thissen &; Steinberg, 1986), this article proposed a new cognitive diagnostic model for graded/polytomous data based on the deterministic input, noisy, and gate (Haertel, 1989; Junker &; Sijtsma, 2001), which is named the DINA model for graded data (DINA-GD). We investigated the performance of a full Bayesian estimation of the proposed model. In the simulation, the classification accuracy and item recovery for the DINA-GD model were investigated. The results indicated that the proposed model had acceptable examinees' correct attribute classification rate and item parameter recovery. In addition, a real-data example was used to illustrate the application of this new model with the graded data or polytomously scored items. 相似文献

Despite the fact that planning has been found to be a significant predictor of reading (particularly of reading comprehension), much less is known about its contribution to mathematics. The purpose of this study was to examine the role of two levels of planning (operation planning and action planning) in three mathematical skills (calculation fluency, math problem-solving, and math reasoning). Eighty Grade 2 children from Shanghai, China were assessed on measures of nonverbal cognitive ability (nonverbal matrices), working memory (digit span backwards and N-back), operation planning (matching numbers, planned codes, and planned search), action planning (crack the code), and mathematics (calculation fluency, math problem-solving, and math reasoning). The results of regression analyses showed that both levels of planning accounted for unique variance in mathematics over and above the effects of nonverbal cognitive ability and working memory. The effects of action planning were particularly strong in math problem-solving. These findings suggest that measures of planning could be used along with measures of working memory to detect children at-risk for mathematics disabilities and that intervention programmes targeting planning could be developed to boost children's mathematics performance. 相似文献

Self‐esteem and culture: Differences in cognitive self‐evaluations or affective self‐regard? 总被引:1,自引:0,他引:1

Although people from East Asian countries consistently report lower self-esteem than do those from Western countries, the origins of this difference are unclear. We conducted two studies to illuminate this issue. Study 1 found that Chinese participants appraised themselves less positively than American participants on a cognitive measure of self-evaluations, but cultural differences were absent on a measure of affective self-regard. Moreover, cultural differences in global self-esteem were eliminated once cognitive self-evaluations were statistically controlled. Study 2 found that cultural differences in modesty underlie cultural differences in cognitive self-evaluations. These findings suggest that Chinese feel as positively toward themselves as Americans do, but are less inclined to evaluate themselves in an excessively positive manner. 相似文献

使用Reed设计的有意遗忘研究范式,以194名小学二、三、四、五年级学生和大学生为被试,考察不同年龄阶段被试工作记忆中有意抑制能力的差异,探索抑制机制随年龄增长的发展趋势及儿童工作记忆中有意抑制能力发展的敏感期。结果表明:1)大学生被试和儿童被试之间的有意抑制能力存在显著性差异;2)随年龄的增长,工作记忆中有意抑制能力呈递增趋势;3)儿童的有意抑制能力发展在三年级,9、10岁可能存在一个敏感期。 相似文献

We hypothesised that sense of home serves as a buffer against self‐threat. In three experiments, we induced sense of home (vs. control) and assessed its buffering function to threat. Sense of home augmented openness to stereotype threat information (Experiment 1), increased performance on a spatial rotation ability test after stereotype threat (Experiment 2), and reduced the desire for high‐status products following mortality salience (Experiment 3). This “proof of concept” research establishes the buffering potential of sense of home and raises theoretical and practical implications. 相似文献

Avoidance is proposed to be a goal‐directed behavior rather than a behavior that reflects passivity or inaction. To evaluate this proposition, a typology of conflict goals and a typology of conflict avoidance strategies are created, and the relationship between nonavoidance strategies and the elements of these 2 typologies are evaluated within a structural equation model (N = 352). Findings show that, except for pretending and withdrawal, conflict goals successfully predict avoidance strategies, thereby affirming their strategic importance. The article concludes by addressing areas for future research, including modifications and refinement of the typologies and proposing other strategies and goals that may be theoretically significant. 相似文献
