Examining the Library as a Site for Intervention: A Mixed-Methods Case Study Evaluation of the “Innovative Solutions to Homelessness” Project     

Teresa Hill  Katherine A. Tamminen 《图书馆管理杂志》2020,60(5):470-492

Abstract

This study examined a project that delivered social work services to homeless individuals. A mixed-methods case study was conducted using quantitative and qualitative data from 93 library employees and the project’s Homelessness Prevention Outreach Worker (HPOW). There was an increase in the number of clients accessing community supports during the project, and the HPOW was integral to the provision of support and resources to homeless individuals. Staff training was associated with significantly greater knowledge, comfort, and skills in working with homeless individuals. These findings can inform the delivery and implementation of similar programs for homeless individuals.  相似文献

Twiplomacy in the age of Donald Trump: Is the diplomatic code changing?     

Maja Šimunjak  Alessandro Caliandro 《The Information Society》2019,35(1):13-25

This study employs digital methods in conjunction with traditional content and discourse analyses to explore how the US President Donald Trump conducts diplomacy on Twitter and how, if at all, diplomatic entities around the world engage in diplomatic exchanges with him. The results confirm speculations that Trump’s diplomatic communication on Twitter disrupts traditional codes of diplomatic language but show little evidence that new codes of diplomatic interactions on social media are being constructed, given that other diplomatic entities around the world mostly remain within the confines of traditional notions of diplomacy in (not) communicating with Trump on Twitter.  相似文献   

Network ethnography applied: understanding the evolving health and physical education knowledge landscape     

Leigh Sperka  Eimear Enright 《Sport, Education and Society》2019,24(2):168-181

The progressively global, neoliberal, privatised, and digital education environment poses new methodological challenges for educational researchers, prompting a need to innovate. It has been suggested, however, that better commentary and reflection on methodological innovation in education is required. This paper considers the benefits and challenges associated with the use of network ethnography, one methodological approach that has emerged to address new social complexities. We explain the rationale for, and process of, this methodology through reference to an illustrative case: a network ethnography of the outsourcing of Health and Physical Education (HPE) curricular work to external providers. In doing this we map and critique three interrelated activities (i.e. Internet searches, interviews, and network diagram construction) that constituted our network ethnography. The discussion turns to how network ethnography allowed us to access new knowledge about the outsourcing of HPE curricular work to external providers by, for example, facilitating us in asking different questions, and foregrounding various stakeholders, networks and relationships that we may not have discovered had we relied on other approaches. This illustrative case demonstrates the capacity of network ethnography to generate rich data and offers a provocation for educational researchers to consider expanding their methodological repertoire.  相似文献   

Teaching to discuss controversial public issues in fragile times: Approaches of Israeli civics teacher educators     

《Teaching and Teacher Education》2020

Civics teachers play a critical role in maintaining classroom environments that encourage discussions of controversial public issues. Thus, preparing new teachers to consider the role of such discussions is crucial. Building on theories of teacher knowledge development, this study explores how Israeli civics teacher-educators conceptualize discussions as part of their courses. The findings present four approaches that include: discussion as a pedagogical practice; discussion as a means for reflection; discussion as a way to bring the curriculum to life; and discussion as a vehicle that represents disciplinary content. Based on these findings, the role of discussion as an educational goal, not just a secondary means, will be argued.  相似文献

The application of inertial measurement units and functional principal component analysis to evaluate movement in the forward 3½ pike somersault springboard dive     

Cherie Walker  John Warmenhoven  Peter J. Sinclair 《Sports biomechanics / International Society of Biomechanics in Sports》2019,18(2):146-162

Based on technological and analytical advances, the capability to more accurately and finitely examine biomechanical and skill characteristics of movement has improved. The purpose of this study was to use Inertial Measurement Units (IMUs) and Functional Principal Components Analysis (fPCA) to examine the role of movement variability (assessed via angular velocity), on 2 divers (1 international level; 1 national) performing the forward 3½ pike somersault dive. Analysis of angular velocity curves during ive-flight identified 5 fPCs, accounting for 96.5% of movement variability. The national diver’s scatter plots and standard deviation of fPC scores illustrated larger magnitudes of angular velocity variability across dive flight. For fPC1 and fPC3, magnitudes of SD variability were 282.6 and 201.5, respectively. The international diver illustrated more consistent angular velocity profiles, with clustering of fPCs scores (e.g., fPC1 & 3 = SD’s of 75.2 & 68.0). To account for lower variability in the international diver, the ability to better coordinate movement sequences and functionally utilise feedback in response to initiation of the somersault position is highlighted. Overall, findings highlight how both IMUs and fPCA can more holistically and finitely examine the biomechanical and skill characteristics of movement sequences with the capability to inform athlete development.  相似文献   

Twenty-four-hour movement behaviours and fundamental movement skills in preschool children: A compositional and isotemporal substitution analysis     

Jéssica Gomes Mota  Cain Craig Truman Clark  Luís Lemos  Cézane Priscilla Reuter  Jorge Augusto Pinto Silva Mota 《Journal of sports sciences》2020,38(18):2071-2079

ABSTRACT

Studies that have analysed the association between the different movement behaviours and fundamental movement skills (FMS) have considered it in an independent manner, disregarding the compositional nature of 24-h movement behaviours (24-h MB). The aim of this study was to investigate the relationship between the 24-h MB and FMS in preschoolers using a compositional data analysis . Two hundred and four preschoolers (4.5 ± 0.8 years old; 101 boys) provided objectively assessed physical activity (PA) and sedentary behaviour (SB) data (Actigraph wGT3X), and FMS (TGMD-2). Sleep duration (SD) was reported by parents. Association of daily composition of movement behaviours with FMS was explored using compositional analysis and isotemporal substitution (R Core Team, 3.6.1). When considered as a 24-h MB composition (PA, SB and SD), adjusted for age, BMI and sex, the composition predicted locomotor (r² = 0.31), object control (r² = 0.19), and total motor score (r² = 0.35), respectively (all P < 0.001). Reallocation of time from light to moderate-to-vigorous PA was associated with greatest positive changes in total motor score. Achieving adequate balance between movement behaviours over the 24-h period, and its relationship with locomotor and object control skills should be considered and further investigated in early childhood.  相似文献   

Teachers’ epistemic cognition in situ: Evidence from classroom assessment     

《Contemporary educational psychology》2020

Assessment tasks require the coordination of multiple knowledge-related goals for various audiences, and therefore provide an authentic context to observe teachers’ epistemic cognition in practice. In this instrumental case study, we investigated seven, fifth grade English Language Arts teachers’ epistemic cognition as they evaluated students’ classroom assessments. Our analyses revealed that the components of epistemic cognition identified in the literature emerged in these teachers’ assessment processes. Moreover, we found evidence that teachers’ epistemic cognition was iterative and nuanced, and required shifts in aims and reliable processes. This resulted in teachers forming new kinds of “epistemic matters” and questions beyond those ideas noted in existing models of epistemic cognition. Significance and implications are discussed.  相似文献   

Independent reading in rural China’s elementary schools: A mixed-methods analysis     

《International Journal of Educational Development》2020

Independent reading—unassigned reading for personal pleasure—has been shown to be an important driver of reading skills and academic success. Children that commonly read for pleasure exhibit higher academic performance. However, little research has been done on independent reading in rural China, where the education system is charged with schooling tens of millions of students. Many rural students fall behind their urban counterparts in school, with potentially troubling implications for China’s ongoing development. This article explores the prevalence of independent reading and its associations with reading ability and academic performance among rural students. Using a mixed methods approach, we analyze quantitative data from a survey of 13,232 students from 134 rural schools and interviews with students, teachers, principals, and caregivers. We find that independent reading is positively and significantly correlated with reading ability as well as standardized math and Chinese tests scores. Despite such correlations, only 17 percent of students report reading for pleasure for an hour a day. Interview findings suggest that inaccessible bookstores, curriculum constraints, unsupportive home environments, low availability of appealing and level-appropriate books, and insufficient school investment in reading resources may explain the low prevalence of independent reading.  相似文献
