Adjoined Piecewise Linear Approximations (APLAs) for Equating: Accuracy Evaluations of a Postsmoothing Equating Method     

Tim Moses 《Journal of Educational Measurement》2013,50(4):427-446

The purpose of this study was to evaluate the use of adjoined and piecewise linear approximations (APLAs) of raw equipercentile equating functions as a postsmoothing equating method. APLAs are less familiar than other postsmoothing equating methods (i.e., cubic splines), but their use has been described in historical equating practices of large‐scale testing programs. This study used simulations to evaluate APLA equating results and compare these results with those from cubic spline postsmoothing and from several presmoothing equating methods. The overall results suggested that APLAs based on four line segments have accuracy advantages similar to or better than cubic splines and can sometimes produce more accurate smoothed equating functions than those produced using presmoothing methods.  相似文献   

The Need for Critical Media Literacy In Teacher Education Core Curricula     

Michele S. Moses  Amy N. Farley 《Educational Studies A Journal of the American Educational Studies Association》2013,49(3):260-279

The "information era" has brought up new literacies, although most of them are still not part of the K–12 curriculum or the teacher education curriculum. One of these new literacies is critical media literacy. The purpose of this article is to document the urgency for including this new literacy in school and teacher education curricula given the crucial role of media as they touch every issue impacting human life in society. Critical media literacy as understood here includes three dimensions: (1) develop a critical understanding of how corporate for-profit media work, driven by their political and economic vested interests; (2) search for and support alternative, nonprofit media; and (3) characterize the role of teachers in helping students and their parents to become media-literate users and supporters of alternative media. Critical media literacy is founded on the legitimate role of media to serve the public's right to be truly informed, and thereby serve democracy. However, currently we are witnessing an unprecedented concentration of for-profit media into conglomerates, in alliance with the government and especially with the federal regulating agency—Federal Communications Commission—and other powerful institutions and corporations. Starting with this big picture, we examine and document specific cases that illustrate how these conglomerates and their allies work to keep and to expand their power, by means of filtering information, manufacturing consent, and controlling what the public watch, listen to, read, think, believe, taste, dress, look like, speak, and how they perceive themselves. The propaganda behind the banning of bilingual education in California is a clear example in the educational arena of the role of media in helping powerful people to manufacture voters' consent through fabricated stories, misleading ballot question, biased polls, etc. The second dimension of critical media literacy refers to the active involvement of every person, including school children, to support and advocate for alternative, nonprofit, public service-driven media. Given the reasons and the evidence presented, the authors consider that there is an urgency for including critical media literacy in the K–12 school curricula, and therefore in the teacher education core curriculum.  相似文献   

The effect of free primary education policy on late school entry in urban primary schools in Kenya     

Moses W. Ngware  Moses Oketch  Alex C. Ezeh  Maurice Mutisya 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2013,59(5):603-625

Late school entry is driven by several factors, one of the key ones being the cost barrier to schooling. Policies such as free primary education (FPE) that advocate for universal coverage are therefore partly aimed at removing the cost barrier. The Kenyan Government, like many in sub-Saharan Africa (SSA), introduced FPE in 2003 with the aim of universalising access to schooling, which is one of the eight United Nations Millennium Development Goals (MDGs) it signed up to achieve. Based on a case study of four sites in Nairobi, the aim of this paper is to assess whether the FPE policy has affected late enrolment. The data used were collected by the African Population and Health Research Center (APHRC) and comprise a sub-sample of 4,325 first-graders during 2000–2005. The paper applies a probit model to assess the impact of the policy on the basis of marginal effects on the predicted probability of late enrolment. The results show that the FPE policy reduces the probability of late enrolment by 14 per cent. The reduction in probability of late enrolment was greater among children residing in slums (16 per cent) than those in non-slums (9 per cent). The main implication of the findings for policy makers is that cost barriers are a likely cause of over-age enrolment.  相似文献   

Intensity of exercise recovery,blood lactate disappearance,and subsequent swimming performance     

James D. Greenwood  G. Edward Moses  F. Mark Bernardino  Glenn A. Gaesser 《Journal of sports sciences》2013,31(1):29-34

Abstract

The aim of this study was to examine the effects of active versus passive recovery on blood lactate disappearance and subsequent maximal performance in competitive swimmers. Fourteen male swimmers from the University of Virginia swim team (mean age 20.3 years, s = 4.1; stature 1.85 m, s = 2.2; body mass 81.1 kg, s = 5.6) completed a lactate profiling session during which the speed at the lactate threshold (V_LT), the speed at 50% of the lactate threshold (V_LT.5), and the speed at 150% of the lactate threshold (V_LT1.5) were determined. Participants also completed four randomly assigned experimental sessions that consisted of a 200-yard maximal-effort swim followed by 10 min of recovery (passive, V_LT.5, V_LT, V_LT1.5) and a subsequent 200-yard maximal effort swim. All active recovery sessions resulted in greater lactate disappearance than passive recovery (P < 0.0001 for all comparisons), with the greatest lactate disappearance associated with recovery at V_LT (P = 0.006 and 0.007 vs. V_LT.5 and V_LT1.5 respectively) [blood lactate disappearance was 2.1 mmol · l^?1 (s = 2.0), 6.0 mmol · l^?1 (s = 2.6), 8.5 mmol · l^?1 (s = 1.8), and 6.1 mmol · l^?1 (s = 2.5) for passive, V_LT.5, V_LT, and V_LT1.5 respectively]. Active recovery at V_LT and V_LT1.5 resulted in faster performance on time trial 2 than passive recovery (P = 0.005 and 0.03 respectively); however, only active recovery at V_LT resulted in improved performance on time trial 2 (TT₂) relative to time trial 1 (TT₁) [TT₂?TT₁: passive +1.32 s (s = 0.64), V_LT.5+1.01 s (s = 0.53), V_LT?1.67 s (s = 0.26), V_LT1.5?0.07 s (s = 0.51); P < 0.0001 for V_LT). In conclusion, active recovery at the speed associated with the lactate threshold resulted in the greatest lactate disappearance and in improved subsequent performance in all 14 swimmers. Our results suggest that coaches should consider incorporating recovery at the speed at the lactate threshold during competition and perhaps during hard training sessions.  相似文献

Executive accounts of theory-of-mind development   总被引：9，自引：0，他引：9  

Moses LJ 《Child development》2001,72(3):688-690

Two varieties of executive theories may be distinguished: emergence accounts and expression accounts. The meta-analytic findings are fully consistent with emergence accounts of theory of mind and do not entirely rule out expression accounts.  相似文献

Educational expansion in Ghana: Economic assumptions and expectations     

Caine Rolleston  Moses Oketch 《International Journal of Educational Development》2008

The neo-classical ‘human capital theory’ continues to be invoked as part of the rationale for educational expansion in the developing world. While the theory provides a route from educational inputs to economic outputs in terms of increased incomes and standards of living, the route is contingent and relies upon a number of key assumptions. This study examines these assumptions alongside student expectations of their educations in the context of Ghana using data collected from a survey conducted at higher education institution and from the Ghana Statistical Service's ongoing living standards surveys. Data indicate that students have high economic expectations but that trends in wages and employment are leading to ‘wage compression’ which may ultimately make expectations difficult to fulfill. The relatively low private costs of education, particularly higher education, may mean, however, that educational investment remains very much a ‘rational’ choice in economic terms. However, the study finds that key assumptions of successful human capital investment went largely unsatisfied in Ghana.  相似文献
