In light of the concepts of appropriation and essentialism, othering, and binary oppositions, the author will examine the interrelation between various feminist theories and gender representation in multicultural children and young-adult literature. Additionally, the author will address the practical implications of those theories and concepts for the classroom. 相似文献

The current study investigated the development of children's performance on tasks that have been suggested to underlie early mathematics skills, including measures of cardinality, ordinality, and intelligence. Eighty‐seven children were tested in their first (T1) and second (T2) school year (at ages 5 and 6). Children's performance on all tasks demonstrated good reliability and significantly improved with age. Correlational analyses revealed that performance on some mathematics‐related tasks were nonsignificantly correlated between T1 and T2 (number line and number comparison), showing that these skills are relatively unstable. Detailed analyses also indicated that the way children solve these tasks show qualitative changes over time. By contrast, children's performance on measures of intelligence and nonnumerical ordering abilities were strongly correlated between T1 and T2. Additionally, ordering skills also showed moderate to strong correlations with counting procedures both cross‐sectionally and longitudinally. These results suggest that, initially, mathematics skills strongly rely on nonmathematical abilities. 相似文献

In three studies we looked at two typical misconceptions of probability: the representativeness heuristic, and the equiprobability bias. The literature on statistics education predicts that some typical errors and biases (e.g., the equiprobability bias) increase with education, whereas others decrease. This is in contrast with reasoning theorists’ prediction who propose that education reduces misconceptions in general. They also predict that students with higher cognitive ability and higher need for cognition are less susceptible to biases. In Experiments 1 and 2 we found that the equiprobability bias increased with statistics education, and it was negatively correlated with students’ cognitive abilities. The representativeness heuristic was mostly unaffected by education, and it was also unrelated to cognitive abilities. In Experiment 3 we demonstrated through an instruction manipulation (by asking participants to think logically vs. rely on their intuitions) that the reason for these differences was that these biases originated in different cognitive processes. 相似文献

Item Response Theory (IRT) models were applied to investigate the psychometric properties of the Arthur and Day's Advanced Progressive Matrices-Short Form (APM-SF; 1994) [Arthur and Day (1994). Development of a short form for the Raven Advanced Progressive Matrices test. Educational and Psychological Measurement, 54, 395–403] in order to test if the scale is a reliable and valid tool to assess general fluid ability in a short time frame. The APM-SF was administered to 2264 high-school and university students. Once attested the one-factor structure of the scale, unidimensional IRT analyses for dichotomous data were applied to investigate the increases in item difficulty levels, Test Information Function, and Differential Item Functioning across age, gender, and country (comparing Italian and British respondents). Additionally, validity measures were reported. Findings attest that the Arthur and Day's APM-SF is a sound instrument for assessing fluid ability within a short time frame. 相似文献

目的:评价瞬时受体电位通道(TRP通道)TRPV1、TRPA1和TRPM8拮抗剂在小鼠神经源性、持续性和神经病理性疼痛模型中的作用。方法:通过辣椒素实验、异硫氰酸烯丙酯(AITC)实验和福尔马林实验,评估TRP通道拮抗剂在小鼠神经源性疼痛模型中的镇痛作用;通过建立紫杉醇诱导的小鼠神经病理性疼痛模型,对TRP通道拮抗剂的抗痛觉(冷、热、触觉)过敏效应进行评估;通过旋转法实验对小鼠的运动协调性进行评估。结论:TRP通道家族包含了不同的小鼠疼痛模型。TRP通道拮抗剂能减轻神经源性、持续性和神经病理性疼痛,但是其镇痛效果与疼痛模型有关。 相似文献
