Teacher turnover in urban schools is occurring at a breakneck pace; thus, it is important for us to understand the characteristics of teachers who stay and succeed in these settings. In order to address this need, this study examines the preparation and induction experiences of teachers who completed a Transition to Teaching – a funded urban apprenticeship program. Three research questions guided the study: (1) How do participants describe the characteristics that influence their five-year retention? (2) How do participants describe their success as teachers? and (3) How do participants describe the professional support they received in their preparation program and during the subsequent four years after completing the program? Quantitative and qualitative data via interviews, focus group, and an examination of teachers’ district performance scores were utilized, as a means of understanding teachers’ staying and impact power. Staying power refers to the ability to endure or last within challenging contexts by possessing strength enough to persevere. Impact power refers to their ability to influence student learning. Four assertions describe the factors influencing developing teachers who stay and have impact as they teach in challenging urban schools, suggesting that these teachers possess a strong work ethic, seek specific resources to improve pedagogy, have the knowledge and skills necessary to differentiate instruction, and seek teacher leadership opportunities in their schools. This study suggests several implications for teacher educators, educational leaders, administrators, and researchers working with new teachers in urban schools or with populations that are predominantly children of color.  相似文献

This article explores variations in mental health and service utilization across academic disciplines using a random sample of undergraduate and graduate students (N = 64,519) at 81 colleges and universities. We report prevalence of depression, anxiety, suicidality, and self-injury, and rates of help-seeking across disciplines, including results from multivariate logistic regressions. We find significant variations: Students in humanities and art and design are significantly more likely to have mental health problems; and for students with apparent mental health problems, treatment rates are lowest among those in business and engineering. Noting these variations could enhance efforts to promote student mental health, particularly within academic departments.  相似文献

In recent years, the advent of low-cost digital and mobile devices has led to a strong expansion of social interventions, including those that try to improve student learning and literacy outcomes. Many of these are focused on improving reading in low-income countries, and particularly among the most disadvantaged. Some of these early efforts have been called successful, but little credible evidence exists for those claims. Drawing on a robust sample of projects in the domain of mobiles for literacy, this article introduces a design solution framework that combines intervention purposes with devices, end users, and local contexts. In combination with a suggested set of purpose-driven methods for monitoring and evaluation, this new framework provides useful parameters for measuring effectiveness in the domain of mobiles for literacy.  相似文献

Caffeine and coffee are widely used among active individuals to enhance performance. The purpose of the current study was to compare the effects of acute coffee (COF) and caffeine anhydrous (CAF) intake on strength and sprint performance. Fifty-four resistance-trained males completed strength testing, consisting of one-rep max (1RM) and repetitions to fatigue (RTF) at 80% of 1RM for leg press (LP) and bench press (BP). Participants then completed five, 10-second cycle ergometer sprints separated by one minute of rest. Peak power (PP) and total work (TW) were recorded for each sprint. At least 48 hours later, participants returned and ingested a beverage containing CAF (300?mg flat dose; yielding 3–5?mg/kg bodyweight), COF (8.9?g; 303?mg caffeine), or placebo (PLA; 3.8?g non-caloric flavouring) 30 minutes before testing. LP 1RM was improved more by COF than CAF (p?=?.04), but not PLA (p?=?.99). Significant interactions were not observed for BP 1RM, BP RTF, or LP RTF (p?>?.05). There were no sprint?×?treatment interactions for PP or TW (p?>?.05). 95% confidence intervals revealed a significant improvement in sprint 1 TW for CAF, but not COF or PLA. For PLA, significant reductions were observed in sprint 4 PP, sprint 2 TW, sprint 4 TW, and average TW; significant reductions were not observed with CAF or COF. Neither COF nor CAF improved strength outcomes more than PLA, while both groups attenuated sprint power reductions to a similar degree. Coffee and caffeine anhydrous may be considered suitable pre-exercise caffeine sources for high-intensity exercise.  相似文献

In this paper we focus on the lived experiences of multidisciplinary scholars as we navigated and coalesced into a productive, interdisciplinary collaboration. We pull from our foundations in feminist methodology and provide excerpts from personal journals and reflexive group interviews to provide a behind-the-scenes account of the inner workings of a feminist research group. While sharing a common research goal, each member negotiated her personal, conceptual, and epistemological stances as we produced an effective, interdisciplinary pastiche. Throughout this process, we worked to create a non-hierarchical atmosphere, continuously and ethically questioned our methods, and incorporated reflexivity in the research processes. In addition to sharing our past experiences, we note challenges we encountered and offer practical suggestions based on the lessons we learned through this collaboration.  相似文献

Recent legislation in England has encouraged the use of disagreement resolution and mediation and emphasised the need to involve pupils in their own schooling. These policies apply in the educational system generally, but are particularly significant in the area of special educational needs (SEN). Kirstie Soar, a lecturer in the School of Psychology at the University of East London; Katie Burke, a PhD student at Salford University, Manchester; Katia Herbst, an independent researcher offering research and development services to the not-for- profit sector; and Professor Irvine Gersch, Director of the MSc educational psychology programme at the University of East London, set out to examine how pupil involvement in informal disagreement resolution has developed across 11 English regions since its introduction. The research consisted of 12 in-depth interviews with local education authority (LEA) SEN officers, mediators and parent partnership officers (PPOs) involved in informal special educational needs disagreement resolution. The aims of the study were to determine how far children were actually involved in mediation and what, if any, barriers existed which were seen to restrict such pupil involvement. A thematic analysis of interview content was conducted. Four major themes emerged, including: the distinction between direct and indirect pupil involvement; the importance of the child's view and how it is elicited; the role of other agencies; and other barriers to pupil involvement in informal disagreement resolution. Direct pupil involvement was found to be limited and variable, but indirect pupil involvement was more prevalent. In this article, the authors note a series of recommendations concerning pupil involvement in the mediation process and, in conclusion, put forward the implications of their work for future policy, practice and research.  相似文献

Even at the primary level, computational thinking (CT) can support young students to prepare for participating in futures that are immersed in data. In mathematics classrooms, there are few explanations of the ways CT can support students in formulating and solving complex problems. This paper presents an example of a primary classroom investigation (8-9 year olds) over seven lessons of the problem “How long does it take to read a book?” The aim is to illustrate ways a statistical investigation can provide context for CT and demonstrate how the two complement each other to solve problems involving mathematics. The findings highlight opportunities and challenges that students face across the elements of CT—decomposition, abstraction, pattern recognition and modelling, and generalization and algorithmic thinking, including recommendations for teaching.  相似文献

This article examines how we use mobile telephony to maintain our physically and socially closest social circle. The analysis is based on traffic data gathered from Norway using approximately 24 million calls and texts made by private individuals. Previous research has shown that our temporal and spatial movement is highly predictable and that the majority of calls and text messages are sent to only four to six different persons. This article extends this research by examining both tie strength and the distance between the interlocutors in urban and rural settings. The findings show that even as information and communication technologies (ICTs) potentially put the world at our fingertips, the mobile phone is an instrument of a more limited geographical and social sphere. Approximately two-thirds of our calls/texts go to strong ties that are within a 25-km radius.  相似文献
