Assessments and examinations play a critical role in certifying student achievement in secondary education. Prompted by concerns about the negative effects of examinations on curriculum, teaching and learning, elements of School-Based Assessment (SBA) have been introduced into certification systems, sometimes modelled on practice in other jurisdictions. This case study investigates factors influencing efforts to introduce SBA in lower secondary education in the Republic of Ireland and reactions from the main stakeholders. Policymakers’ perspectives were informed by national consultations, results of international assessments, trends towards skills-based curricula and practices in relation to SBA as part of high-stakes assessment internationally. Despite broad enthusiasm for the reforms from most stakeholders, teachers remained opposed. A series of compromise proposals shifted the reforms far from their intended nature, leaving in place a dual system of assessment that incorporates continued centralised examining by the state along with some non-certified SBA by teachers. The efficacy of this solution in relation to the original aims of the reform remains to be seen. The analysis explores relevant substantive and methodological issues. The complex interplay between international, national and very local influences on policy implementation is highlighted, suggesting the need for due diligence in anticipating and managing stakeholder responses to reform initiatives. Readers’ attention is also drawn to the intricacy of undertaking qualitative case study inquiry and the need for awareness in relation to possible alternative interpretations of data.  相似文献

This article seeks to provide a school perspective on the nature and quality of the partnerships which schools form with businesses in order to deliver work placements and workplace learning in Australia. It found that the ability of schools to engage with external partners depended on the ability of school leaders to define and communicate the role of VET within the school and its broader community. This dependence on individuals and leadership is vulnerable to changes in key personnel and the informality of some of the processes and relationships can lead to problems in monitoring, evaluating and replicating programmes. Our study shows that a balance is required between carefully documented processes and the flexibility required to operate programmes successfully. The study also noted the tension between the perceived needs of the school and those of industry. A successful partnership necessarily requires school flexibility – in the decisions as to what programmes should be offered and how work placements and timetabling should be organised.  相似文献

Improvements in running economy (RE) are thought to lead to improvements in running performance (P). Multiple interventions have been designed with the aim of improving RE in middle and long-distance runners. The aim of this study was to assess the effect of interventions of at least 2-weeks’ duration on RE and P and to determine whether there is a relationship between changes in RE (ΔRE) and changes in running performance (ΔP). A database search was carried out in Web of Science, Scopus and SPORTDiscus. In accordance with a PRISMA checklist 10 studies reporting 12 comparisons between interventions and controls were included in the review. There was no correlation between percentage ΔRE and percentage ΔP (r = 0.46, P = 0.936, 12 comparisons). There was a low risk of reporting bias but an unclear risk of bias for other items. Meta-analyses found no statistically significant differences between interventions and controls for RE (SMD (95% CI) = ?0.37 (?1.43, 0.69), 204 participants, p = 0.49) or for P (SMD (95% CI) = ?0.65 (?26.02, 24.72, 204 participants, p = 0.99). There is a need for studies of greater statistical power, methodological quality, duration and homogeneity of intervention and population. Standardised measures of performance and greater control over non-intervention training are also required.  相似文献

There is little published data in relation to the effects of caffeine upon cycling performance, speed and power in trained cyclists, especially during cycling of approximately 60 s duration. To address this, eight trained cyclists performed a 1 km time-trial on an electronically braked cycle ergometer under three conditions: after ingestion of 5 mg x kg-1 caffeine, after ingestion of a placebo, or a control condition. The three time-trials were performed in a randomized order and performance time, mean speed, mean power and peak power were determined. Caffeine ingestion resulted in improved performance time (caffeine vs. placebo vs. control: 71.1 +/- 2.0 vs. 73.4 +/- 2.3 vs. 73.3 +/- 2.7 s; P = 0.02; mean +/- s). This change represented a 3.1% (95% confidence interval: 0.7-5.6) improvement compared with the placebo condition. Mean speed was also higher in the caffeine than placebo and control conditions (caffeine vs. placebo vs. control: 50.7 +/- 1.4 vs. 49.1 +/- 1.5 vs. 49.2 +/- 1.7 km x h-1; P = 0.0005). Mean power increased after caffeine ingestion (caffeine vs. placebo vs. control: 523 +/- 43 vs. 505 +/- 46 vs. 504 +/- 38 W; P = 0.007). Peak power also increased from 864 +/- 107 W (placebo) and 830 +/- 87 W (control) to 940 +/- 83 W after caffeine ingestion (P = 0.027). These results provide support for previous research that found improved performance after caffeine ingestion during short-duration high-intensity exercise. The magnitude of the improvements observed in our study could be due to our use of sport-specific ergometry, a tablet form and trained participants.  相似文献

School self-evaluation allows staff to review the quality of their work in relation to local contexts. In this article, Peter Neil, senior lecturer in education, Alex McEwen, professor of education, and Karen Carlisle and Damian Knipe, both research assistants in the Graduate School of Education at Queen's University, Belfast, discuss a research project focusing on the process of self-evaluation carried out by staff at a special school in Northern Ireland. The project involved the participants in the completion of a research journal over a four-week period. The authors describe the ways in which the outcomes of the project were fed back to staff and the impact the project had on a range of issues, including teaching and learning and the school's professional development agenda.  相似文献

Whether hierarchical logistic regression can reduce the sample size requirement for estimating optimal cutoff scores in a course placement service where predictive validity is measured by a threshold utility function is explored. Data from courses with varying class size were randomly partitioned into two halves per course. Non-hierarchical and hierarchical analyses were performed on each half. Compared to their nonhierarchical counterparts, hierarchically estimated cutoff scores from different halves were more stable and predicted course outcomes in the other half more accurately. These differences were most pronounced with small samples. Sample size requirements for developing cutoff scores for course placement can be substantially reduced if hierarchical logistic regression is used.  相似文献

No Child Left Behind (NCLB) performance mandates, embedded within state accountability systems, focus school AYP (adequate yearly progress) compliance squarely on the percentage of students at or above proficient. The singular importance of this quantity for decision-making purposes has initiated extensive research into percent proficient as a measure of school quality. In particular, technical discussions have scrutinized the impact of sampling, measurement, and other sources of error on percent proficient statistics. In this article, we challenge the received orthodoxy that measurement error associated with individual students' scores is inconsequential for aggregate percent proficient statistics. Synthesizing current classification accuracy research with techniques from randomized response designs, we establish results which specify the extent to which measurement error—manifest as performance level misclassifications—produces bias and increases error variability for percent at performance level statistics. The results have direct relevance for the design of coherent and fair accountability systems based upon assessment outcomes.  相似文献
