This paper reports our experiences in working with precollege and undergraduate American Indian students. In 1990, we began a fourth-grade after-school science program for 30 American Indian students. At the present time the program, called Scientific Knowledge for Indian Learning and Leadership (SKILL), involves over 200 American Indian 4th-9th grade students in weekly science/mathematics activities, quarterly Saturday seminars, and summer science camps. We have collected data to try to determine factors that help to improve student attitudes towards mathematics and science. Conclusions are drawn from these analyses and from our own subjective observations. The development of American Indian involvement in undergraduate science and engineering education on our campus has been aided by the establishment of an American Indian Science and Engineering Society (AISES) chapter and also by the promotion of collaborative learning. A comparison of our observations in the framework of other more well-established programs is given. Changes that have occurred as a result of both precollege and college activities are described and discussed. It appears that each of these activities has had beneficial influences on the other. We also report problems and concerns as well as recommendations to other groups or institutions who may be embarking on similar endeavors.  相似文献

When an HIV-positive woman becomes pregnant, additional nutritional considerations are warranted. Compared to routine prenatal nutritional assessment and intervention, pregnant HIV-positive women have increased needs to promote a healthy outcome. This column contains information on HIV and pregnancy, nutrition and infection, and nutrition for HIV-positive pregnancy. This content can be integrated into childbirth education settings to improve care to women who are HIV-positive.  相似文献

The purpose of this study was to examine slopes from curriculum-based measures of writing (CBM-W) as indicators of growth in writing. Responses to story prompts administered for 5 min to 89 students in Grades 2–5 were collected across 12 weeks and scored for correct word sequences (CWS) and correct minus incorrect sequences (CIWS). Linear mixed modeling revealed that, for students in Grades 2–3, a linear model with random effects on both intercept and slope fit the data best. For students in Grades 4–5, growth trends varied depending on number of weeks and scoring procedure used. The time point at which slopes were significantly different from zero varied by scoring procedure and grade. Gender was related to intercept and slope for CWS and CIWS in Grades 2–3 and to intercept and linear slope for CWS and CIWS in Grades 4–5. Findings suggest that CBM-W may be appropriate for monitoring student progress, and that gender should be considered in data-based decision making.  相似文献

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
