ABSTRACTThe State of Alaska, by some measures the United States’ most rural state, has long supported correspondence schools, a popular school choice option available to all students statewide and used primarily by homeschooled students. This paper first explores Alaska correspondence schools in historical context, and then quantifies capture rate, enrollment by race/ethnicity, grade distributions, and cohort graduation rates for the years 2010–17. Findings include a steady increase in the proportion of Alaskan students enrolled in correspondence schools between 2010 and 2017; disproportionate enrollment of Alaskan students identified as White in correspondence schools between 2010 and 2017; enrollment peaks in late high school during 2014–17; and significantly lower 4- and 5-year cohort graduation rates among students enrolled in correspondence schools compared to those enrolled in traditional public schools. 相似文献

Issues linked with the notions of quality of life (QOL) and motivation to learn among Asian medical students have not been
well documented. This is true in both the international and the New Zealand contexts. Our paper addresses this lack of research
by focusing on the QOL of international and domestic Asian students studying in New Zealand, where Asian students form a significant
proportion of tertiary students. Although there is evidence to suggest that Asian students do well academically, it was felt
that an investigation into their QOL would be instructive as QOL will likely have an impact on cognition, behavior, general
well-being, and motivation. The present study surveyed fourth- and fifth-year medical students to examine the relationship
between QOL and motivation to learn and to consider how Asian medical students compare against European medical and non-medical
student peers. The study utilized the World Health Organization—Quality of Life questionnaire (BREF version) and a shortened
version of the Motivated Strategies for Learning Questionnaire. The results show that the Asian medical students in this study
generated significantly lower scores in terms of their satisfaction with social relationships compared with their non-Asian
peers. In addition, international Asian medical students appear to be more at risk than domestic Asian students with respect
to test anxiety. The paper considers the findings and the implications for quality of life, motivation to learn, medical education,
and the Asian student community. 相似文献

The purpose of this study was to examine gender differences in parent–child sex communication for 14 topics among early adolescent African-American youth. Similar to prior research, a larger percentage of participants reported they discussed sex with their mother in comparison to their father. In contrast to prior research, more males than females reported they discussed sexual topics with their mothers and fathers. Binary logistic regression analysis found significant differences for males versus females for father–child conversations on 12 of the 14 topics. Only two of the analyses were significant for males versus females on mother–child discussion of the topics. Finally, parent–child conversations tended to focus on general versus personal information. For example, a larger percentage of participants reported discussing general information on HIV/AIDS compared to discussing sexual orientation. The importance of research that focuses on the role of fathers in parent–child sexual socialisation is discussed. 相似文献

Conditioned attention theory (CAT) of latent inhibition (LI) states that parallel learning processes occur during reinforced and nonreinforced stimulus presentation. The present experiments investigated the effects of nonreinforced preexposure of either a compound CS or elements of that compound which differed in salience. Three predictions were advanced: (1) Both the compound and its elements will show an increase in LI as a function of the number of preexposures; (2) the two elements will show different levels of LI, with more LI accruing to the more salient element; (3) overshadowing will occur during compound preexposure. Two experiments, using rats as subjects and a conditioned suppression test, are reported. In Experiment 1, groups received 0, 20, 40, or 80 nonreinforced preexposures to a compound whose elements differed in salience. The results of the subsequent test confirmed predictions 1 and 2. Experiment 2, in which groups were preexposed to either the elements or the compound, provided evidence for an overshadowing effect, confirming prediction 3 from CAT. 相似文献

The anatomy curriculum at Namibia's first, and currently only, medical school is clinically oriented, outcome-based, and includes all of the components of modern anatomical sciences i.e., histology, embryology, neuroanatomy, gross, and clinical anatomy. The design of the facilities and the equipment incorporated into these facilities were directed toward simplification of work flow and ease of use by faculty, staff, and students. From the onset, the integration of state of the art technology was pursued to facilitate teaching and promote a student-centered pedagogical approach to dissections. The program, as realized, is comprised of three 16-week semesters with seven hours of contact time per week, namely three hours of lectures and four hours of dissection laboratory and microscopy time. Set outcomes were established, each revolving around clinical cases with integrated medical imaging. The design of the facility itself was not constrained by a legacy structure, allowing the School of Medicine, in collaboration with architects and contractors, to design the building from scratch. A design was implemented that allows for the sequential processing of cadaveric material in a unidirectional flow from reception, to preparation, embalming, storage, dissection, and maceration. Importantly, the odor of formaldehyde typically associated with anatomy facilities was eliminated outside of the dissection areas and minimized within via a high-performance ventilation system. By holistically incorporating an integrated curriculum, facility design, and teaching at an early stage, the authors believe they have created a system that might serve as a model for new anatomy programs. 相似文献

Significant U.S. policy initiatives in the late 1990s were intended to control Internet access, privacy, and indecency--specifically among children. This study reflects on these using quantitative data from a computer center in a children's library in the inner city. Researchers gathered 16 weeks of page requests ( n = 203,647) using "click stream" and behavioral data, and analyzed these using nonparametric tests. Findings show that users are highly influenced by each other and browse only a small universe of sites. Game playing and communicating with individuals (via e-mail and chat) were the most popular uses. Children were uninterested in pornography and sites directed toward children. Advertising was extremely common. Children were most likely to engage in sharing when using games and chat. For this population, access, privacy and indecency initiatives to control Internet use fails to achieve its stated goals, but activities that encourage sharing in public places hold some promise for building computer knowledge. 相似文献
