This research focuses on understanding teachers’ conceptions of what constitutes a fair assessment. In recent decades the number of studies seeking to learn about teachers’ conceptions on assessment has multiplied. The idea is simple, and involves the extent to which conceptions have an effect on what happens in practice. With this aim, a phenomenographic study was carried out to understand what is a fair assessment from teachers’ perspectives. Despite the importance of conducting phenomenographic studies in education, in Spain hardly any studies have used this methodology. Participants were 30 teachers at primary/secondary schools in Spain. The results show that teachers' conceptions of fair assessment were divided, some being more closely related to the principle of equality and others to equity. The conclusion of this study highlights the influence of the school context on teachers’ conceptions of what constitutes fair assessment (in the research, there were 15 teachers who worked in schools located in low socioeconomic status contexts and 15 who were in high socioeconomic status environments). 相似文献

In this paper, we explore the developmental challenges facing the academic profession in Europe and especially in some Western Balkan countries, Croatia and Slovenia. First, we look at how the higher education environment determines key changes to the academic profession: expectations to demonstrate professional expertise, internationalisation, segmentation, and precarity. While these processes are mainly considered from the above perspective, we also examine the work of academics from within. Second, we discuss aspects of academic tasks, challenges of synchronising academic work with performance measures, intensification of work and expansion of bureaucratic tasks. Building on these perspectives, we introduce a qualitative pilot study that tests how these general trends described in the literature may be applied to given situations in five countries of former Yugoslavia: Slovenia, Croatia, Serbia, North Macedonia and Kosovo. Although these countries cover a relatively small geographical area, the differences among them with respect to the economy, society and politics are important. Our findings suggest that problems accumulating in academic work in Slovenia and Croatia were in almost all of the surveyed aspects less problematic than in the three other observed countries. 相似文献

新中国成立初期体育学界的探索和体育事业的发展,为当代体育哲学社会科学发展提供了重要的经验启示和思想资源。出于复杂原因,当时被"双百"方针孕育而生的首次体育学术论争,鲜有人提及。在学界内外争鸣氛围的激励下,这次论争系统总结了当时体育发展中的基本问题,空前活跃了体育研究氛围,也促使篮球战术、体育内行与外行、武术渊源和发展等具体问题的讨论得以深入展开;而历史条件的特殊性和局限性,致使其偏离了体育场域且未能充分关注基本国情;从研究者的态度、论争者的遗憾和体育界的反思等层面,对我国首次体育学术论争及其深远影响进行研判。 相似文献

ABSTRACTThe aim of this study was to investigate the differences and long-term reliability in perceptual, metabolic, and neuromuscular responses to velocity loss resistance training protocols. Using a repeated, counterbalanced, crossover design, twelve team-sport athletes completed 5-sets of barbell back-squats at a load corresponding to a mean concentric velocity of ~0.70 m·s?1. On different days, repetitions were performed until a 10%, 20% or 30% velocity loss was attained, with outcome measures collected after each set. Sessions were repeated after four-weeks. There were substantial between-protocol differences in post-set differential ratings of perceived exertion (dRPE, i.e., breathlessness and leg muscles, AU) and blood lactate concentration (B[La], mmol·L?1), such that 30%>20%>10% by small to large magnitudes. Differences in post-set countermovement jump (CMJ) variables were small for most variables, such that 30%<20%<10%. Standard deviations representing four-week variability of post-set responses to each protocol were: dRPE, 8–11; B[La], 0.8–1.0; CMJ height, 1.6–2.0; CMJ PPO, 1.0–1.8; CMJ PCV, 0.04–0.06; CMJ 100ms-Impulse, 5.7–11.9. Velocity loss thresholds control the magnitude of perceptual, metabolic, and neuromuscular responses to resistance training. For practitioners wanting to reliably prescribe training that can induce a given perceptual, metabolic, or neuromuscular response, it is strongly advised that velocity-based thresholds are implemented. 相似文献

Despite the success of academic advising dashboards in several higher educational institutions (HEI), these dashboards are still under-explored in Latin American HEI's. To close this gap, three different Latin American universities adapted an existing advising dashboard, originally deployed at the KU Leuven to their own context. In all three cases, the context was the main ruling factor to these adaptations. In this paper, we describe these adaptions using a framework that focuses on four different elements of the context: Objectives, Stakeholders, Key moment and Interactions. Evaluation of the adapted dashboards in the three different Latin American universities is conducted through pilots. This evaluation shows the value of the dashboard approach in different contexts in terms of satisfaction, usefulness and impact in academic decision-making and advising tasks. The main contribution of this paper is the systematic reporting of the adaptations to an academic advising dashboard and showing the value of an academic advising dashboard on academic decision-making and advising tasks. 相似文献

Research on teacher-student relationships shows their impact on students. However, it typically focuses on teachers’ interactions and instruction, with less attention to motivations/feelings. Specifically, almost no quantitative research has focused on teachers’ caring for students, despite its potential importance. The present multilevel study, comprising 675 students in ages 15–17 and their 33 homeroom teachers, linked students’ feelings that their teacher cares for them with their self-esteem, well-being, and school engagement and indicated that teacher-student relationships quality mediates these links. Furthermore, students’ reports on teachers’ caring were associated with teachers’ sense of meaning at work, suggesting its role in enhancing caring. 相似文献
