Tackling Suboptimal Bachelor��s Degree Completion Rates Through Training in Self-Regulated Learning (SRL)     

Todd D. Reeves  Amy E. Stich 《Innovative Higher Education》2011,36(1):3-17

In response to both problematic and extant gaps in Bachelor??s degree completion rates, this mixed methods study investigated whether a theoretically based undergraduate course intervention measurably contributed to participants?? competence as self-regulated learners. Respective quantitative and qualitative analyses of data collected from two samples showed that intervention participants experienced growth in the targeted self-regulatory constructs. Moreover, differential effects by race/ethnicity and gender were not observed. We conclude with a discussion of this study??s implications for institutions of higher education, pertinent considerations in designing and implementing this self-regulated learning intervention, and a review of the literature on effective practices for doing so.  相似文献   

Head injury secondary to suspected child maltreatment: results of a prospective Canadian national surveillance program     

Bennett S  Ward M  Moreau K  Fortin G  King J  Mackay M  Plint A 《Child abuse & neglect》2011,35(11):930-936

Objective

We sought to determine the incidence, clinical features, and demographic profile of head injury secondary to suspected child maltreatment (abuse or neglect) in Canada to help inform the development and evaluation of prevention programs for abusive head injuries.

Methods

From March 1, 2005 to February 28, 2008, an average of 2,545 paediatricians and paediatric subspecialists were surveyed monthly through the established network of the Canadian Paediatric Surveillance Program. We calculated incidence rates using the number of confirmed cases over the product of the duration of the study (3 years) and population estimates by age group.

Results

There were 220 confirmed cases of head injury from suspected child maltreatment. The annual incidence rate was 14.1 per 100,000 for children less than 1 year of age and 1.4 per 100,000 for those less than 15 years. Seventy three percent (141) of cases involved infants less than 12 months of age and 52% (100) of cases involved infants less than 6 months of age. Seventy-five percent (165) of cases presented to the emergency room. With regard to outcome, 12% (27) of cases resulted in death and 45% (75) of survivors had neurological sequelae at discharge. Thirty percent (67) of all cases, as well as 30% (8) of deaths were previously known to child welfare authorities.

Conclusion

This study provides an estimate of the rate of head injury secondary to suspected child maltreatment in Canada. The young age and poor medical outcomes of those involved highlights the need for prevention efforts that are implemented early in life. Given that a significant percentage of injured infants and children were already known to child welfare authorities, the study also highlights the need to establish and evaluate additional preventive efforts for parents and caregivers already in the child welfare system.  相似文献   

Valuing the benefits of the education provided by public universities: A case study of Minnesota     

Amy Damon  Paul Glewwe 《Economics of Education Review》2011,30(6):1242-1261

This study estimates the value of the private and public benefits that accrue to Minnesota residents from state government subsidies to higher education. In 2005, the University of Minnesota and the Minnesota State Colleges and Universities system received $832 million from Minnesota's state government to support educational programs. These subsidies allow these institutions to offer lower tuition rates, increasing the number of Minnesotans with bachelor and graduate degrees. We calculate that removing these subsidies would eventually lead to 14,000 fewer graduate degree holders in Minnesota, and reduce those with bachelor's degrees or “some college” by 42,000. The annual economic cost of these subsidies is about $326 million; this is less than annual state appropriations because most of those appropriations are income transfers from taxpayers to students, not an economic cost. We estimate that the annual value of the benefits of these subsidies is between $531 and $786 million ($381 and $570 million) when a 3% (5%) discount rate is used. We also discuss some of the income distribution consequences.  相似文献   

Gender Gaps in Collegiate Teaching Style: Variations by Course Characteristics     

Thomas F. Nelson Laird  Amy K. Garver  Amanda Suniti Niskodé-Dossett 《Research in higher education》2011,52(3):261-277

Using data from over 9,000 faculty members that participated in the Faculty Survey of Student Engagement (FSSE), this study examined the moderating role a range of course characteristics played on the effects of gender on the percentage of class time spent on various activities, a measure of teaching style. Results revealed gender differences, but that the gaps between men and women in lecturing and active classroom practices varied by disciplinary area, course level, and the number of times a course had been taught by the same instructor. The results confirm that gender effects depend on context, which implies that efforts to improve teaching and learning must also adapt to the instructional context.  相似文献   

Murdered bread, living bread: Doris Grant and the homemade, wholemeal loaf     

Whipple AC 《Endeavour》2011,35(2-3):99-106

Doris Grant (1905-2003), a middle-class, British housewife, published numerous books from the 1940s into the 1970s urging her fellow housewives to bake organic, wholemeal bread for their families. This article argues that Grant's arguments defy easy categorization as either 'conservative' or 'progressive'. On the one hand, her targeted appeal to women reflected a traditional, conservative understanding of gender roles: women were, first and foremost, wives and mothers and therefore naturally responsible for family diet and health. On the other hand, Grant also pushed her readers to look beyond their homes and recognize a dangerous food supply system that was impinging on their daily lives. She demanded that her readers reject comfortable complicity in this system and preached the value of individual action in effecting substantive change.  相似文献   

A parallel microfluidic channel fixture fabricated using laser ablated plastic laminates for electrochemical and chemiluminescent biodetection of DNA     

Edwards TL  Harper JC  Polsky R  Lopez DM  Wheeler DR  Allen AC  Brozik SM 《Biomicrofluidics》2011,5(4):44115-4411514

Herein is described the fabrication and use of a plastic multilayer 3-channel microfluidic fixture. Multilayer devices were produced by laser machining of plastic polymethylmethacrylate and polyethyleneterapthalate laminates by ablation. The fixture consisted of an array of nine individually addressable gold or gold/ITO working electrodes, and a resistive platinum heating element. Laser machining of both the fluidic pathways in the plastic laminates, and the stencil masks used for thermal evaporation to form electrode regions on the plastic laminates, enabled rapid and inexpensive implementation of design changes. Electrochemiluminescence reactions in the fixture were achieved and monitored through ITO electrodes. Electroaddressable aryl diazonium chemistry was employed to selectively pattern gold electrodes for electrochemical multianalyte DNA detection from double stranded DNA (dsDNA) samples. Electrochemical detection of dsDNA was achieved by melting of dsDNA molecules in solution with the integrated heater, allowing detection of DNA sequences specific to breast and colorectal cancers with a non-specific binding control. Following detection, the array surface could be renewed via high temperature (95 °C) stripping using the integrated heating element. This versatile and simple method for prototyping devices shows potential for further development of highly integrated, multi-functional bioanalytical devices.  相似文献   

Membrane-integrated microfluidic device for high-resolution live cell imaging     

Epshteyn AA  Maher S  Taylor AJ  Holton AB  Borenstein JT  Cuiffi JD 《Biomicrofluidics》2011,5(4):46501-465016

The design and fabrication of a membrane-integrated microfluidic cell culture device (five layers,≤500 μm total thickness) developed for high resolution microscopy is reported here. The multi-layer device was constructed to enable membrane separated cell culture for tissue mimetic in vitro model applications and pharmacodynamic evaluation studies. The microdevice was developed via a unique combination of low profile fluidic interconnect design, substrate transfer methodology, and wet silane bonding. To demonstrate the unique high resolution imaging capability of this device, we used oil immersion microscopy to image stained nuclei and mitochondria in primary hepatocytes adhered to the incorporated membrane  相似文献   

Assessing Quality in Toddler Classrooms Using the CLASS-Toddler and the ITERS-R     

Karen M. La Paro  Amy C. Williamson  Bridget Hatfield 《Early education and development》2014,25(6):875-893

Many very young children attend early care and education programs, but current information about the quality of center-based care for toddlers is scarce. Using 2 observation instruments, the Infant/Toddler Environment Rating Scale–Revised (ITERS-R) and the Classroom Assessment Scoring System, Toddler Version (CLASS-Toddler), 93 child care classrooms for toddlers across the state of North Carolina, representing a range of quality, were assessed to determine overall quality, and associations between observed quality and teachers' ratings of child behavior problems and competence outcomes using the Brief Infant Toddler Social Emotional Assessment. Research Findings: Findings indicated that overall, toddler classrooms were rated as being of moderate quality. Associations between observed quality and teacher-reported child behavior problems and competence outcomes indicated that CLASS-Toddler ratings were positively associated with fewer behavior problems; specifically, children in classrooms with higher levels on the CLASS-Toddler domains of Emotional and Behavioral Support as well as Engaged Support for Learning were reported to have fewer behavior problems. Similarly, the ITERS-R subscales of Interaction and Listening and Talking were positively related to fewer reported behavior problems. Regression models showed that the CLASS-Toddler Emotional and Behavioral Support domain predicted differences in child behavior problems. Practice or Policy: Findings suggest the need for additional research related to very young children's experiences in center-based child care to examine associations between quality and child experiences and outcomes. Children's experiences over time need to be examined to understand how these early child care experiences are related to children's later school adjustment and performance. On a related note, professional development for teachers in toddler classrooms needs to be addressed in terms of preparing effective teachers for young children during the toddler developmental period.  相似文献   

A Behind‐the‐Scenes Guide to School‐Based Research

Schools are an important context for both basic and applied scientific research. Unlike the laboratory, however, the physical and social conditions of schools are not under the exclusive control of scientists. In this article, we liken collecting data in schools to putting on a theatrical production. We begin by describing the large cast of characters whose collaborative efforts make school‐based research possible. Next, we address the critics, including the university Institutional Review Board (IRB) and school administrators, whose feedback often improves the final study design. We then turn our attention to set building, stage directions, and rehearsals—key steps in the iterative process of refining study procedures. We end with a discussion of the day of data collection itself and activities that take place after the curtain drops. Throughout, we make recommendations based on our recent experience collecting data at several high schools.  相似文献   

An Experimental Evaluation of Guided Reading and Explicit Interventions for Primary-Grade Students At-Risk for Reading Difficulties     

Carolyn A. Denton  Jack M. Fletcher  W. Pat Taylor  Amy E. Barth  Sharon Vaughn 《Journal of research on educational effectiveness》2014,7(3):268-293

Abstract

Considerable research evidence supports the provision of explicit instruction for students at risk for reading difficulties; however, one of the most widely implemented approaches to early reading instruction is Guided Reading (GR; Fountas & Pinnel, 1996), which deemphasizes explicit instruction and practice of reading skills in favor of extended time reading text. This study evaluated the two approaches in the context of supplemental intervention for at-risk readers at the end of Grade 1. Students (n = 218) were randomly assigned to receive GR intervention, explicit intervention (EX), or typical school instruction (TSI). Both intervention groups performed significantly better than TSI on untimed word identification. Significant effects favored EX over TSI on phonemic decoding and one measure of comprehension. Outcomes for the intervention groups did not differ significantly from each other; however, an analysis of the added value of providing each intervention relative to expected growth with typical instruction indicated that EX is more likely to substantially accelerate student progress in phonemic decoding, text reading fluency, and reading comprehension than GR. Implications for selection of Tier 2 interventions within a response-to-intervention format are discussed.  相似文献
