The socioeconomic attainment gap in mathematics starts early and increases over time. This study aimed to examine why this gap exists. Four-year-olds from diverse backgrounds were randomly allocated to a brief intervention designed to improve executive functions (N = 87) or to an active control group (N = 88). The study was preregistered and followed CONSORT guidelines. Executive functions and mathematical skills were measured at baseline, 1 week, 3 months, 6 months, and 1 year posttraining. Executive functions mediated the relation between socioeconomic status and mathematical skills. Children improved over training, but this did not transfer to untrained executive functions or mathematics. Executive functions may explain socioeconomic attainment gaps, but cognitive training directly targeting executive functions is not an effective way to narrow this gap.  相似文献

Framed within intersectionality and using science identity as a unit of analysis, in this single case study I explore the barriers, difficulties, and conflicts that Amina, a young Muslim woman, immigrant in Western Europe confronted throughout her trajectory in physics and the ways in which her multiple identities intersected. The main sources of data consisted of three long biographical interviews, which were analyzed through a constant comparative method. The analysis of the data provided insights into how intrapersonal, interpersonal, sociocultural factors, alongside a myriad of experiences nurtured Amina's intersectional identities and what this may mean for Muslim women's participation in physics. The findings are summarized in two main assertions: (a) Amina was confronted with various barriers across her journey in physics with the intersection of religion and gender being the major barrier to her perceived recognition due to cultural expectations, sociopolitical factors, and negative stereotypes and (b) Amina's social class, religion, gender performance, and ethnic status positioned her as Other in various places throughout her trajectory in physics, and consequently hindered her sense of belonging. These findings suggest the urgency and importance of: (a) examining the intersection of science identity with other identities, especially, religion, gender, and ethnicity for the purpose of extrapolating a more comprehensive understanding of how minoritized groups participate in science; (b) rethinking recognition through an explicit intersectionality lens across various geographical and sociopolitical contexts; and (c) transforming physics into a diverse world where multiple ways of being are recognized, where minoritized groups will not have to compartmentalize parts of their identities to exist, and where they can perform their authentic and intersectional identities.  相似文献

Abstract

This article opens up the question of modernity in relation to Yan’an woodcuts by recounting the Matisse debate among artists in Yan’an circa 1942, during the War of Resistance against Japanese occupation. Yan’an woodcuts did not move in a direction akin to the stylistic reform engaged by Western modernism; instead they pushed modern Chinese woodcuts to develop according to the requirements of ‘national form.’ Yan’an woodcut artists’ exploration of ‘national form’ involved a synthesis of folk aesthetics and woodcut techniques with the creation of modern‐style woodcuts, and a synthesis of revolutionary content with the artistic expression of national form. In this way a new kind of artistic ideal was realized. Compared with contemporary artistic questions in the West, the formal questions of Chinese revolutionary art surpassed the artistic as such to support rich social content and revolutionary discourse. The establishment of national language in art accords with the desire and imagination to construct of a new kind of modern nation‐state.  相似文献

There is limited research on the types of peer feedback exchanged during triadic supervision. Through a content analysis, the authors found that students provided feedback about counseling performance and cognitive counseling skills most often in supervision sessions. However, there were differences in the types of feedback exchanged across three experience levels.  相似文献

This study investigated written language production in 10‐year‐old children with impaired reading comprehension. Despite fluent and accurate reading, these children are poor at understanding what they read. Participants completed a spelling test, and were asked to write an extended narrative, prompted by a series of pictures. Poor comprehenders showed age‐appropriate spelling skills, and their narratives did not differ from those produced by control children in terms of length or syntactic complexity. However, their narratives captured less of the story content, and contained a less sophisticated story structure. These findings are discussed within a framework that sees weaknesses in aspects of oral language placing constraints on aspects of written language production.  相似文献

It is difficult for rats to learn to go to an arm of a T-maze to receive food that is dependent on the time of day, unless the amount of food in each daily session is different. In the same task, rats show evidence of time–place discriminations if they are required to press levers in the arms of the T-maze, but learning is only evident when the first lever press is considered, and not the first arm visited. These data suggest that rats struggle to use time as a discriminative stimulus unless the rewards/events differ in some dimension, or unless the goal locations can be visited prior to making a response. If both of these conditions are met in the same task, it might be possible to compare time–place learning in two different measures that essentially indicate performance before and after entering the arms of the T-maze. In the present study, we investigated time–place learning in rats with a levered T-maze task in which the amounts of food varied depending on the time of day. The first arm choices and first lever presses both indicated that the rats had acquired time–place discriminations, and both of these measures became significantly different from chance during the same block. However, there were subtle differences between the two measures, which suggest that time–place discrimination is aided by visiting the goal locations.  相似文献
