Longstanding explanations of the controlling effect of white consumers/producers on minority production can obscure the negotiation and struggle of artists over their images, and particularly the ways in which dominant ideologies can be disarticulated from their meanings and rearticulated as critical observations on contemporary social relations. Rap group dead prez's video for the song “Hell Yeah!” is most accurately read from the perspective of articulation theory, since the group's oppositional use of the “gaze” reworks dominant representational discourses of race and class. 相似文献

As digital media devices have been increasingly used in early childhood educational settings, this study examined whether the iPad with a Vygotskian social development approach—namely, More Knowledgeable Other—can be integrated into low-income preschool classrooms to improve science learning. An analysis of variance was used to examine the overall improvement and differences in improvement among English language learners, children with special needs, and children without special needs or English language learner status. Results showed that all participants improved their science learning abilities as a consequence of the iPad instruction. Among all groups, English language learner children benefitted more than the other groups, but only with a game that had less verbal directions. There were no significant differences by gender. 相似文献

This article describes a graduate-level qualitative research course informed by transformational learning theory. It presents strategies an interdisciplinary team of instructors used to engage and support students as they entered and moved through the course. The strategies focused on creating a safe, supportive, learner-centered environment, fostering critical reflection, engaging in ongoing discourse, and focusing on the centrality of experience by situating cognition in the personal context of students' lives and the research process itself. 相似文献

In this study 20 beginning special education teachers were asked to describe their experiences in general education settings. To provide data, each teacher completed approximately three electronic reflective journals during a school year and also participated in a phone interview, which was aimed to give in-depth information regarding the participants’ comments in the journals. The participants described their experiences in regard to collaboration with mainstream teachers, the delivery of the curriculum and the understanding of their role with reference to identity. They reported some good experiences but also many difficulties in their attempts to support pupils with special educational needs (SEN) and enhance their learning and participation in mainstream schools. Challenges in collaboration, the delivery of the curriculum and the development of teachers’ identity at the beginning of a career in special education are discussed. We argue that the teachers’ experiences are associated with the legislative educational system and the school culture which does not encourage collaborative practices but rather promotes individualism and leads to exclusive practices. 相似文献

As English-only efforts continue in the US schooling system, dual-language programs have served as attempts to preserve students’ home language. An after-school, dual-language, Spanish–English, mathematics program, Los Rayos was developed in a predominantly Mexican/Mexican–American neighborhood in Chicago. As participant observers with a sociocultural perspective, we explored the linguistic and personal resources used by participating 4th grade bilingual Latina/o students. We found that students used imaginative, playful, and hybrid linguistic resources to make sense of and solve probability tasks when engaged within a zone of mathematical practice. Results challenge narrow perspectives on bilingual students’ linguistic resources. Language implications are discussed. 相似文献

需求弹性是经济学中的基础概念,也是我国煤炭市场化进程中的重要研究对象.不同于以往的宽泛研究,本文分别从国家维度、时间维度和区域维度对1995-2010年间的我国煤炭需求弹性展开系统化研究.基于面板数据模型的研究发现全国煤炭需求的价格弹性为0.59,煤炭在所考察期间总体呈现出刚性需求现象,但基于截面数据的回归结果显示各考察年份的煤炭需求弹性为负值且存在着较大的时间波动,而各区域时间序列的回归结果表明煤炭需求弹性的区际差异: 煤炭主产地其值为负,消费地其值为正.分析发现以国家维度和时间维度的研究结论相互矛盾,而以区域维度的研究结果更加科学合理,具有更为可靠的理论和现实指导意义. 相似文献
