School-based early intervention and later child maltreatment in the Chicago Longitudinal Study     

Reynolds AJ  Robertson DL 《Child development》2003,74(1):3-26

Investigated were the effects of participation in the Title I Child-Parent Centers (CPC) on substantiated reports of child maltreatment for 1,408 children (93% of whom are African American) in the Chicago Longitudinal Study. The CPCs provide child education and family support services in high-poverty areas. After adjusting for preprogram maltreatment and background factors, 913 preschool participants had significantly lower rates of court petitions of maltreatment by age 17 than 495 children of the same age who participated in alternative kindergarten interventions (5.0% vs. 10.5%, a 52% reduction). Participation for 4 to 6 years was significantly associated with lower rates of maltreatment (3.6% vs. 6.9%, a 48% reduction). Findings based on child protective service records (as well as combined protective service and court records) were similar. Preschool length, family risk, and school poverty were associated with lower rates of maltreatment. Parental involvement in school and school mobility were significant mediators of intervention effects.  相似文献   

Engaging distance and on-campus students in problem-based learning   总被引：1，自引：1，他引：0  

L. M. Brodie  M. Porter 《European Journal of Engineering Education》2008,33(4):433-443

The University of Southern Queensland in Australia offers multiple entry pathways to a suite of integrated programs delivered to on-campus and distance-education students. The programs cover 2–5 years in nine majors. A specially designed strand of four integrated courses using problem-based learning (PBL) was incorporated into programs and replaced some traditionally taught (lecture) content-based courses. The first offer of the new foundation course took place in 2002. It has since been recognised through a number of national and international awards. For the initial offer, delivering a PBL course to distance engineering students working in virtual teams had never been done before in the world. It is currently delivered to approximately 400 students annually. Student feedback indicates that the course successfully inculcates attributes such as teamwork, communication and the ability to solve technical problems. All these attributes have been identified as being desirable by professional and industry bodies around the world.  相似文献   

Childcare Educators’ Perceptions of and Solutions to Reducing Sitting Time in Young Children: A Qualitative Study     

Yvonne G. Ellis  Dylan P. Cliff  Anthony D. Okely 《Early Childhood Education Journal》2018,46(4):377-385

Young children spend a high proportion of their time at childcare sitting. Reducing sitting time or breaking up prolonged periods of sitting may be positively associated with health outcomes among children. The purpose of this study was to identify childcare educators’ perceptions of what environmental and policy modifications could be made within early childhood education and care (ECEC) settings to reduce sitting time among children during childcare. Eighty-seven educators from 11 ECEC centres participated in 11 focus groups between September 2013 and November 2013. Each focus group was audio-recorded and transcribed verbatim. A semi-structured schedule was developed to investigate the educators’ perceptions of the influences on children’s sitting time at childcare. A problem–solution tree was developed to determine potential solutions for reducing total and prolonged sitting time in young children at childcare. Most educators were unaware of the high levels of sitting time among young children. Educators identified that childcare practices, the physical environment and the weather were factors that influenced children’s sitting time. Potential solutions to reduce sitting time were to break-up prolonged sitting time by using movement breaks, standing desks, movement transitions between activities, relocating key facilities around the space to promote movement, and integrating movement during learning activities. Also, educators suggested that posters could be used to increase awareness among educators about the benefits of reducing sitting time. Educators identified key practices that could be modified to reduce young children’s sitting time in childcare. These potential solutions should be evaluated to understand their effectiveness.  相似文献   

Using Multisite Experiments to Study Cross-Site Variation in Treatment Effects: A Hybrid Approach With Fixed Intercepts and a Random Treatment Coefficient     

Howard S. Bloom  Stephen W. Raudenbush  Michael J. Weiss  Kristin Porter 《Journal of research on educational effectiveness》2017,10(4):817-842

The present article considers a fundamental question in evaluation research: “By how much do program effects vary across sites?” The article first presents a theoretical model of cross-site impact variation and a related estimation model with a random treatment coefficient and fixed site-specific intercepts. This approach eliminates several biases that can arise from unbalanced sample designs for multisite randomized trials. The article then describes how the approach operates, explores its assumptions, and applies the approach to data from three large welfare-to-work trials. The article also illustrates how to report cross-site impact findings and presents diagnostics for assessing these findings. To keep the article manageable, it focuses on experimental estimates of effects of program assignment (effects of intent to treat), although the ideas presented can be extended to analyses of multisite quasi-experiments and experimental estimates of effects of program participation (complier average causal effects).  相似文献   

Computer science concept inventories: past and future     

C. Taylor  D. Zingaro  L. Porter  K.C. Webb  C.B. Lee  M. Clancy 《Computer Science Education》2014,24(4):253-276

Concept Inventories (CIs) are assessments designed to measure student learning of core concepts. CIs have become well known for their major impact on pedagogical techniques in other sciences, especially physics. Presently, there are no widely used, validated CIs for computer science. However, considerable groundwork has been performed in the form of identifying core concepts, analyzing student misconceptions, and developing CI assessment questions. Although much of the work has been focused on CS1 and a CI has been developed for digital logic, some preliminary work on CIs is underway for other courses. This literature review examines CI work in other STEM disciplines, discusses the preliminary development of CIs in computer science, and outlines related research in computer science education that contributes to CI development.  相似文献   

Twenty five years of cognitive care education research: Time for a revolutionary change     

Russell Porter  Jeremy Berry  Kellie Cude  Stephen Anderson  Sanfrena Britt 《Educational gerontology》2018,44(2-3):82-89

This is the third study of Cognitive Care Education in New York State nursing homes using cross-sectional methods over a 25 year period. The data indicate that the Cognitive Care Education increased at statistically significant levels, albeit by evolutionary means. It is now time for “A Revolutionary Change,” for Cognitive Care Education, whereby the ideal level of 20 to 32 hours of education is provided to cognitive care providers.

Cognitive care encompasses a range of behavioral problems that require appropriate education. These might include communication difficulties, perseveration (repetition of an idea or activity), aggressive behaviors, paranoia, memory problems, and wandering (Savundranayagam & Orange, 2014). This study assessed Cognitive Care Education as the “Amount and type of education provided to cognitive care providers on how to care for the cognitively impaired including knowledge and skills to understand cognitive impairments and requisite standards to improve quality of care and life.”

It is apparent that nursing home employees are cognizant of cognitively impaired residents’ needs. However, the Cognitive Care Education providers receive on the job, is still inadequate to understand the overall needs of cognitively impaired, as indicated by our most recent research in 2016 (i.e., 3.81 hours). We recommend that at least 20 hours of Cognitive Care Education be provided to care providers, with a second recommendation that 32 hours would be ideal that follows the Alzheimer’s Association recommendation. The primary focus of the research studies here is to ensure care-providers are adequately trained to take care of the cognitively impaired.  相似文献

Alignment as a Teacher Variable     

Andrew C Porter  John Smithson  Rolf Blank  Timothy Zeidner 《教育实用测度》2013,26(1):27-51

Essay scores generated by machine and by human raters are generally comparable; that is, they can produce scores with similar means and standard deviations, and machine scores generally correlate as highly with human scores as scores from one human correlate with scores from another human. Although human and machine essay scores are highly related on average, this does not eliminate the possibility that machine and human scores may differ significantly for certain gender, ethnic, or country groups. Such differences were explored with essay data from two large-scale high-stakes testing programs: the Test of English as a Foreign Language and the Graduate Record Examination. Human and machine scores were very similar across most subgroups, but there were some notable exceptions. Policies were developed so that any differences between humans and machines would have a minimal impact on final reported scores.  相似文献
