In response to growing income stratification in higher education, President Obama convened a White House Summit in 2014 where over 100 selective institutions committed to increasing the number of low-income students on their campus. One way colleges proposed to do so is through partnerships with college access organizations like QuestBridge, a nonprofit organization that aims to increase the percentage of low-income students at elite universities. While institutions purport that QuestBridge improved socioeconomic diversity, empirical research has not confirmed these claims. In this study, we estimate the effect of QuestBridge on overall access of Pell eligible students at partner institutions using quasi-experimental methods. We find no increase in the economic diversity of colleges after establishing a partnership with QuestBridge, except for colleges simultaneously partnering with QuestBridge and enacting no-loan financial aid policies. We also consider whether participation in QuestBridge increases institutional status through larger application volumes and increased selectivity, and discuss implications for research and practice in the area of stratification. 相似文献

The use of mobile learning in education is growing at an exponential rate. To best understand how mobile learning is being used, it is crucial to gain a collective understanding of the research that has taken place. This systematic review reveals the trends in mobile learning in science with a comprehensive analysis and synthesis of studies from the year 2000 onward. Major findings include that most of the studies focused on designing systems for mobile learning, followed by a combination of evaluating the effects of mobile learning and investigating the affective domain during mobile learning. The majority of the studies were conducted in the area of life sciences in informal, elementary (5–11 years) settings. Mobile devices were used in this strand of science easily within informal environments with real-world connections. A variety of research methods were employed, providing a rich research perspective. As the use of mobile learning continues to grow, further research regarding the use of mobile technologies in all areas and levels of science learning will help science educators to expand their ability to embrace these technologies. 相似文献

In addition to an intrinsic difficulty in reading and spelling, one of the defining characteristics of dyslexia is an enduring and pervasive difficulty in phonological coding, such that dyslexic readers find it particularly challenging to process and manipulate the constituent sounds of a language. Coexistent with this finding is the evidence that some dyslexic readers also demonstrate subtle sensory coding problems in the visual and auditory domains. Few theories have been proposed to unite these different findings within a coherent model of reading. Here the evidence for visual, auditory and phonological coding problems in dyslexia is briefly reviewed, and a hypothesis is proposed for how adequate early sensory coding may be intrinsic to phonological awareness and subsequent reading ability. In this hypothesis, a cortical network is assumed that incorporates the visual, auditory and phonological skills of reading. The visual sub‐component of the network is mediated by the dorsal visual pathway, which is responsible for the accurate spatial encoding of letters, words and text. The auditory component of the network in pre‐readers is intrinsic to the development of phonological sensitivity, and then grapheme‐phoneme assimilation as reading skills develop. In this hypothesis, some of the symptoms of dyslexia may result from subtle problems in the encoding of both visual and auditory information and their role in maintaining the synchronicity of the reading network. 相似文献

Although peer influence is a strong predictor of adolescents’ risk-taking behaviors, not all adolescents are susceptible to their peer group. One hundred and thirty-six adolescents (Mage = 12.79 years) completed an fMRI scan, measures of perceived peer group norms, and engagement in risky behavior. Ventral striatum (VS) sensitivity when anticipating social rewards and avoiding social punishments significantly moderated the association between perceived peer norms and adolescents’ own risk behaviors. Perceptions of more deviant peer norms were associated with increased risky behavior, but only for adolescents with high VS sensitivity; adolescents with low VS sensitivity were resilient to deviant peer norms, showing low risk taking regardless of peer context. Findings provide a novel contribution to the study of peer influence susceptibility. 相似文献

In this study, we use decomposition methods on PISA 2006 data to compare student academic performance across OECD countries.
We first establish an empirical model to explain the variation in academic performance across individuals, and then use the
Oaxaca-Blinder decomposition method to decompose the achievement gap between each of the OECD countries and the OECD average.
Results indicate that the explained portion of the achievement gap varies across countries. In some countries, our empirical
models are able to account for almost all the achievement gap, while unexplained country-specific effects still dominate in
other countries. Finally, we use two Asian countries, Japan and Korea, to demonstrate how to identify major factors that have
contributed to the observed achievement gap across countries. 相似文献

The purpose of this study was to investigate how science faculty members?? belief systems about inquiry-based teaching changed through their experience in a professional development program. The program was designed to support early career science faculty in learning about inquiry and incorporating an inquiry-based approach to teaching laboratories. Data sources for this qualitative study included three semi-structured interviews, observations during the program and during faculty members?? implementation in their courses, and a researcher??s journal. In the first phase of data analysis, we created profiles for each of the four participants. Next, we developed assertions, and tested for confirming and disconfirming evidence across the profiles. The assertions indicated that, through the professional development program, participants?? knowledge and beliefs about inquiry-based teaching shifted, placing more value on student-directed learning and classroom inquiry. Participants who were internally motivated to participate and held incoming positive attitudes toward the mini-journal inquiry-based approach were more likely to incorporate the approach in their future practice. Students?? responses played a critical role in participants?? belief systems and their decision to continue using the inquiry-based format. The findings from this study have implications for professional development design. 相似文献

Women??s colleges and universities persist around the world, even as the vast majority of tertiary institutions are open to men and women. In nearly every nation, women can attend even the most elite formerly all-male universities, and in several nations women are the majority of all college students. Questions therefore arise about the continued need for a single-sex sector in the 21st century. In this study I examined the contribution of these institutions to their national systems of education and society. I used a qualitative, comparative, multiple case study approach to understand 14 diverse women??s colleges and universities in nine nations on five continents. Five key roles emerged: access, campus climate, gender empowerment, leadership development, and cultural paradox. I make recommendations for research and practice. 相似文献

The survey Performance Standards for In-service Teachers is widely used to help describe teacher skills relating to instructional technology for assessment or planning of professional development. It is based on the six constructs of the National Educational Technology Standards for Teachers, and though used broadly in a variety of contexts, it does not appear to have undergone significant independent evaluation of its psychometric properties. Our analysis found that all six subscales possessed strong internal consistency (all α > 0.93). A subsequent confirmatory factor analysis supported both its current six-factor structure as well as a more parsimonious one-factor model. 相似文献
