Does Homeschooling “Work”? A Critique of the Empirical Claims and Agenda of Advocacy Organizations 总被引:1,自引:1,他引:0
Christopher Lubienski Tiffany Puckett T. Jameson Brewer 《Peabody Journal of Education》2013,88(3):378-392
The phenomenal growth of homeschooling in recent years demonstrates not only the appeal of this educational approach but also the notable policy acumen of the homeschooling movement's leading advocates. This analysis examines and critiques the empirical claims made by homeschooling proponents to justify further expansion and deregulation of the movement, and sheds light on the homeschool advocacy agenda explicit in those claims. Advocates often strongly suggest a causal connection between homeschooling and academic success, postsecondary attainment, and even enjoyment of life. Seemingly, these benefits are experienced all at a reduced cost per student. It is through such claims that homeschooling advocates have expanded the practice of homeschooling and have pressed for fewer state regulations and less oversight. This article outlines and challenges those claims, showing the tenuous basis for such conclusions. Instead, in an era when policymakers demand evidence of effective educational practices, we note the remarkable lack of empirical evidence on the effectiveness of this popular approach and suggest that continued efforts to claim such evidence exists indicates the desire of advocates to further advance what is largely an ideological agenda of deregulation as an end in itself. 相似文献

Advanced Placement (AP) Chemistry and the National AP Chemistry Examination are both critical to secondary level institutions nationwide. The use of a national embossing stamp to attest to successful completion of an AP Chemistry course and exam to ensure college credit is a novel idea worth consideration. Moreover, the concept could be expanded to all AP science disciplines conducting laboratory exercises. 相似文献

The most frequently occurring contact events in rugby union are the tackle and ruck. The ability repeatedly to engage and win the tackle and ruck has been associated with team success. To win the tackle and ruck, players have to perform specific techniques. These techniques have not been studied at the highest level of rugby union. Therefore, the purpose of this study was to identify technical determinants of tackle and ruck performance at the highest level of rugby union. A total of 4479 tackle and 2914 ruck events were coded for the Six Nations and Championship competitions. Relative risk ratio (RR), the ratio of the probability of an outcome occurring when a characteristic was observed (versus the non-observed characteristic), was determined using multinomial logistic regression. Executing front-on tackles reduced the likelihood of offloads and tackle breaks in both competitions (Six Nations RR 3.0 Behind tackle, 95% confidence interval [95% CI]: 1.9–4.6, effect size [ES] = large, P < 0.001); Championship RR 2.9 Jersey tackle, 95% CI: 1.3–6.4, ES = moderate, P = 0.01). Fending during contact increased the chances of offloading and breaking the tackle in both competitions (Six Nations RR 4.5 Strong, 95% CI: 2.2–9.2, ES = large, P = P < 0.001; Championship RR 5.1 Moderate, 95% CI: 3.5–7.4, ES = large, P < 0.001). For the ruck, actively placing the ball increased the probability of maintaining possession (Six Nations RR 2.2, 95% CI: 1.1–4.3, ES = moderate, P = 0.03); Championship RR 4.0, 95% CI: 1.3–11.8, ES = large, P = 0.01). The techniques identified in this study should be incorporated and emphasised during training to prepare players for competition. Furthermore, these techniques need to be added to coaching manuals for the tackle and ruck. 相似文献

High rates of pregnancy and sexually transmitted infections play a major role in the physical, mental, and emotional health of young people. Despite efforts to provide sexuality education through diverse channels, we know little about the ways in which young people perceive school- and community-based efforts to educate them about sexual health. Forty-eight African-American young people participated in six focus groups to discuss their sexuality education experiences. Three major themes emerged that highlight experiences and perspectives on optimal strategies for promoting sexual health. These themes were: (1) experiences with school-based sexuality education (SBSE), (2) seeking information outside of schools, and (3) general principles of youth-centred sexuality education. Young people in the focus groups expressed their varying satisfaction with SBSE due to the restricted content covered and lack of comfort with the instruction methods. Participants described how they reached outside of SBSE for sexuality education, turning to those in the community, including local organisations, health care providers, and peers, also expressing variability in satisfaction with these sources. Finally, participants identified three important principles for youth-centred sexuality education: trust and confidentiality, credibility, and self-determination. These findings give voice to the often-unheard perspectives of African-American young people. Based on their responses, it is possible to gain a better understanding of the optimal combination of school-, family-, peer-, and community-based efforts to support young people as they move towards adulthood. 相似文献

Adriana J. Uma?a‐Taylor Stephen M. Quintana Richard M. Lee William E. Cross Jr. Deborah Rivas‐Drake Seth J. Schwartz Moin Syed Tiffany Yip Eleanor Seaton Ethnic Racial Identity in the st Century Study Group 《Child development》2014,85(1):21-39
Although ethnic and racial identity (ERI) are central to the normative development of youth of color, there have been few efforts to bring scholars together to discuss the theoretical complexities of these constructs and provide a synthesis of existing work. The Ethnic and Racial Identity in the 21st Century Study Group was assembled for this purpose. This article provides an overview of the interface of ERI with developmental and contextual issues across development, with an emphasis on adolescence and young adulthood. It proposes a metaconstruct to capture experiences that reflect both individuals’ ethnic background and their racialized experiences in a specific sociohistorical context. Finally, it presents milestones in the development of ERI across developmental periods. 相似文献

AbstractThe Trump Administration’s attempts to rescind trans students’ domestic legislative protections is part of a new period of backlash against trans rights progress globally. This article examines the USA’s changing role concerning trans students in education policy and rights progress internationally. It outlines developments in transnational policy for trans students. It contextualises US leadership in this policy area, particularly US President Obama and US President Trump’s use of executive powers. It considers theoretical conceptualisations of trans rights ‘progress’ using the work of queer and trans theorists, before analysing data from 60 interviews with key informants participating high-level global networking for trans students’ rights, documenting how stakeholders characterise recent US contributions. Several informants identified a period of ‘progress’ in trans rights during the Obama Administration, but others were more sceptical of such claims and critical of recent policy change by the US Government’s Trump Administration. Alternative models for Northern and Southern engagement in global networking for trans students’ rights are outlined and discussed. 相似文献

A Comparison of Student Achievement and Satisfaction in an Online Versus a Traditional Face-to-Face Statistics Class 总被引:2,自引:0,他引:2

In this study we examined differences between online distance education and traditional classroom learning for an introductory undergraduate statistics course. Two outcome dimensions were measured: students final grades and student satisfaction with the course. Using independent samples t-tests, results indicated that there was no significant difference in grades between the online and traditional classroom contexts. However, students enrolled in the online course were significantly less satisfied with the course than the traditional classroom students on several dimensions. This finding is inconsistent with the no significant difference phenomenon, described in Russells (1999) annotated bibliography, which supports minimal outcome differences between online courses and face-to-face courses.Jessica J. Summers and Tiffany A.

A daily diary method was employed to examine the extent to which Chinese adolescents in the United States assist and spend time with their families, and the implications of such behaviors for their involvement in other activities and psychological well-being. Adolescents (N = 140) completed checklists in which they reported their activities and psychological well-being every day for a period of 2 weeks. Adolescents showed a greater propensity to balance family obligations with their academic demands than with their social life with peers on a daily basis. Girls experienced slightly more daily conflict between activities than boys. Neither the extent of involvement in family obligations nor the balancing of family obligations with other activities were associated with psychological distress among adolescents. These findings demonstrate the complex manner in which adolescents from immigrant families attempt to combine their cultural traditions with selected aspects of American society on a daily basis. In contrast to the expectations of some observers, the youths in this study appeared to accomplish such an integration with little cost to their psychological well-being. 相似文献
