Re-visioning Action: Participatory Action Research and Indigenous Theories of Change   总被引：2，自引：0，他引：2  

Eve Tuck 《The Urban Review》2009,41(1):47-65

This article observes that participatory action research (PAR), by nature of being collaborative, necessitates making explicit theories of change that may have otherwise gone unseen or unexamined. The article explores the limits of the reform/revolution paradox on actions and theories of change in PAR. Citing examples from two recent youth PAR projects on educational issues, the author submits that when met with such a paradox, one can only move to a new vantage point. Four alternative vantage points, drawn from Indigenous epistemologies, are illustrated; they are sovereignty, contention, balance, and relationship.

Local amenities,unobserved quality,and market clearing: Adjusting teacher compensation to provide equal education opportunities     

Bradford Tuck  Matthew BermanAlexandra Hill 《Economics of Education Review》2009

Local school districts differ in their ability to pay for teacher quality, and in the amenities they offer as places to live and work. Market clearing with heterogeneous quality yields geographically varying teacher salary levels that confound scarcity with unobserved differences in quality. The paper discusses identification and estimation of a model of quality-adjusted teacher salaries in local markets with unobserved market-clearing prices. Exogenous variables in the model include community and district characteristics, job characteristics and working conditions, and individual characteristics. We apply the model to estimate the relative cost of providing comparably qualified teachers for urban and rural public schools in the state of Alaska, which has high geographic variation in amenities and local financial resources. The quality-adjusted geographic salary differentials implied by the results suggest much larger compensation differentials for isolated rural schools than most of these school districts can afford under current levels of state support.  相似文献   

The impact of gross anatomy on the future head and neck surgeon     

David J. Archibald  Matthew L. Carlson 《Anatomical sciences education》2009,2(2):89-90

Gross anatomy is not only a rite of passage for medical students as they enter the world of practicing medicine but may also be an unrecognized fork in the road in their pursuit of choosing a medical specialty. Otolaryngology: head and neck surgery tends to be poorly represented in medical school curriculum, often only offered as an elective rotation. However, head and neck anatomy remains a constant in most medical schools, granting some exposure to otolaryngology whether students realize it or not. A common thread among most head and neck surgeons in their decision to pursue this surgical specialty is a love for head and neck anatomy, spawned in that first year gross anatomy course. This first and potentially only exposure to otolaryngology should be optimized, as it can have a profound effect in the selection of otolaryngology as a specialty. This introduction can be facilitated by (1) inviting otolaryngology residents to assist during the dissection of the head and neck, (2) soliciting otolaryngology attending physicians to provide clinical correlation lectures, and (3) anatomy professors should identify students who excel in the head and neck portion of the curriculum and direct them towards otolaryngology mentors. There may be a great missed opportunity if a career in otolaryngology is not discussed with students during the dissection of the head and neck.

Evaluating Intervention Effects in a Diagnostic Classification Model Framework          下载免费PDF全文

Matthew J. Madison  Laine Bradshaw 《Journal of Educational Measurement》2018,55(1):32-51

The evaluation of intervention effects is an important objective of educational research. One way to evaluate the effectiveness of an intervention is to conduct an experiment that assigns individuals to control and treatment groups. In the context of pretest/posttest designed studies, this is referred to as a control‐group pretest/posttest design. The transition diagnostic classification model (TDCM) was recently developed to assess growth, defined as change in attribute mastery status over time, in a diagnostic classification model framework. The TDCM, however, does not model multiple groups, and therefore is not able to analyze data from a control‐group pretest/posttest designed experiment. In this study, we extend the TDCM to model multiple groups, thereby enabling the examination of group‐differential growth in attribute mastery and the evaluation of intervention effects. The utility of the multigroup TDCM is demonstrated in the evaluation of an innovative instructional method in mathematics education.  相似文献

Rolling Back Zero Tolerance: The Effect of Discipline Policy Reform on Suspension Usage and Student Outcomes     

Johanna Lacoe  Matthew P. Steinberg 《Peabody Journal of Education》2018,93(2):207-227

Beginning in the early 1990s, states and districts enacted zero-tolerance discipline policies that relied heavily on out-of-school suspensions. Recently, districts nationwide have revised these policies in favor of more tempered disciplinary responses. In 2012–2013, Philadelphia reformed its discipline policy to limit suspensions for nonviolent student misconduct and granted principals greater discretion in responding to more serious occurrences of student misconduct. Employing a difference-in-differences approach, we find that Philadelphia's reform resulted in a modest decline in suspensions for nonviolent infractions in the year of reform; however, total suspensions remained unchanged while serious incidents of student misconduct increased. Further, the truancy rate increased and district math and English language arts achievement declined following the policy reform. These findings should inform policymakers and practitioners on the implications of district-level reforms for suspension usage and the potential consequences for student outcomes.  相似文献   

The influence of successive matches on match-running performance during an under-23 international soccer tournament: The necessity of individual analysis     

Matthew C. Varley  Valter Di Salvo  Mattia Modonutti  Warren Gregson  Alberto Mendez-Villanueva 《Journal of sports sciences》2018,36(5):585-591

This study investigated the effects of successive matches on match-running in elite under-23 soccer players during an international tournament. Match-running data was collected using a semi-automated multi-camera tracking system during an international under-23 tournament from all participating outfield players. Players who played 100% of all group stage matches were included (3 matches separated by 72 h, n = 44). Differences in match-running performance between matches were identified using a generalised linear mixed model. There were no clear effects for total, walking, jogging, running, high-speed running and sprinting distance between matches 1 and 3 (effect size (ES); ?0.32 to 0.05). Positional analysis found that sprint distance was largely maintained from matches 1 to 3 across all positions. Attackers had a moderate decrease in total, jogging and running distance between matches 1 and 3 (ES; ?0.72 to ?0.66). Classifying players as increasers or decreasers in match-running revealed that match-running changes are susceptible to individual differences. Sprint performance appears to be maintained over successive matches regardless of playing position. However, reductions in other match-running categories vary between positions. Changes in match-running over successive matches affect individuals differently; thus, players should be monitored on an individual basis.  相似文献   

Six-year body composition change in male elite senior rugby league players     

Ben Jones  Kevin Till  Gregory Roe  John O’Hara  Matthew Lees  Matthew J. Barlow 《Journal of sports sciences》2018,36(3):266-271

This study investigated the change in body composition and bone mineral content (BMC) of senior rugby league (RL) players between 2008 and 2014. Twelve male professional RL players (age, 24.6 ± 4.0 years; stature, 183.4 ± 8.4 cm) received a dual-energy X-ray absorptiometry scan during preseason in 2008 and 2014. Between 2008 and 2014, very likely increases in leg lean mass (LM), total trunk and leg BMC, and a likely increase in arm BMC and possible increases in body mass (BM), total and trunk fat mass (FM), and total, trunk and arm LM were observed. Unlikely decreases and unclear changes in leg and arm FM were also found. Large negative correlations were observed between age and BM (r = ?0.72), LM (r = ?0.70), FM (r = ?0.61) and BMC (r = ?0.84) change. Three participants (19.1 ± 1.6 years) increased LM by 7.0–9.3 kg. Younger players had the largest increases in LM during this period, although an older player (30-year old) still increased LM. Differences in body composition change were also observed for participants of the same age, thus contextual factors should be considered. This study demonstrates the individuality of body composition changes in senior professional rugby players, while considering the potential change in young athletes.  相似文献   

Are habitual runners physically inactive?     

Timo Rantalainen  Arto J. Pesola  Matthew Quittner  Nicola D. Ridgers  Daniel L. Belavy 《Journal of sports sciences》2018,36(16):1793-1800

The World Health Organisation’s (WHO) physical activity guidelines recommend 150min/week of moderate- to vigorous-intensity physical activity (MVPA) accumulated in 10 min bouts. To see whether people performing habitual exercise for recreation meet these guidelines, 25 long-distance runners [mean 67 km/wk], 25 joggers [mean 28 km/wk], and 20 sedentary adults wore an ActiGraph GT3X+ accelerometer for 7 days. Sedentary time and bouts were similar in runners and sedentary adults (p > 0.46). Sedentary adults performed 20 ± 16 min/day of MVPA (usual bout duration (W50%): 9.53 ± 3.45min), with joggers and runners performing 45 ± 31min (W50%: 16.92 ± 9.53min) and 83 ± 58min (W50%: 20.35 ± 8.85min), respectively (p ≤ 0.001 versus sedentary group). Data showed that 65% of the sedentary group, 32% of joggers and 4% of long-distance runners did not meet the WHO guideline for MVPA. Failure to meet the guideline was most prominent in, but not restricted to, runners who reported ≤50km running per week. Self-reported running does not ensure adults meet physical activity guidelines or offset daily sedentary behaviours. On the other hand, the sedentary group was very close in accumulating recommended bouts of MVPA in incidental activities. Future studies should assess whether modification of work and leisure physical activity would be more fruitful than encouraging recreational exercise per se in meeting physical activity guidelines.  相似文献
