Based on two case studies of Third Sector Organizations (TSOs) working with schools and parents in Catalonia and London, this paper aims to discuss some of the implications of ‘participative’ programmes aimed at involving those migrant families seen by schools as ‘hard to reach’. First, we describe how an ambiguous notion of participation can shift responsibilities to families and leave internal school practices free from critical gaze. Second, we focus on the complexities and tensions involved in the process of partnering TSOs with schools because of the bureaucratic nature of educational institutions and unresolved conflicts of interests and responsibilities. Finally, we argue that the potential of these initiatives were limited and diluted by being stand-alone and time-limited. Our analysis suggests that, in spite of their apparent success, they ended up being part of powerful authorising narratives that justify the outsourcing of public services and the abdication of the State’s responsibilities. 相似文献

The present study, based on the construct comparability approach, performs a comparative analysis of general points average for seven courses, using exploratory factor analysis (EFA) and the Partial Credit model (PCM) with a sample of 1398 student subjects (M = 12.5, SD = 0.67) from 8 schools in the province of Alicante (Spain). EFA confirmed a one-factor model which explains 74.44% of the variance. Cronbach’s alpha value for this factor was .94. The PCM supported the one-factor model, and an optimal fit was achieved in all of the courses. The analysis of differential item functioning showed no significant differences in any course. Equitable distribution was observed in the evolution of the difficulty indices along the measurement scale for each course. This type of analysis confirms the measurement of a single latent construct in the different topics analysed, despite addressing various theoretical and procedural contents. 相似文献

Homework has traditionally been considered positive for students’ academic achievement, to the extent that it makes children more responsible while learning. Nevertheless, making students do a large amount of homework has been one of the most criticised practices in recent years. Parental associations have long held the view that Spanish elementary school pupils spend too much time on homework. This situation is so alarming that it has recently caused a ‘homework strike’, which has been supported by many children's parents. Furthermore, being assigned an excessive amount of homework is a serious problem which extends well beyond Spain. In light of this context, this article aims to provide new evidence on the relationship between homework and academic performance. To carry out this research, rich longitudinal census data, together with a twin fixed-effects approach and value-added models, have been used. In this way, we can control for variables that are the same within twins, allowing us to generate a better understanding of the association between homework time and primary children's academic achievement. Our main finding is that homework is not associated with young people's academic achievement (at least within this specific country context). 相似文献

Anatomical sciences curricula have been under constant reform over the years, with many countries having to reduce course hours while trying to preserve laboratory time. In Mexico, schools have historically been autonomous and unregulated, and data regarding structure and methods are still lacking. A national survey was sent by the Mexican Society of Anatomy to 110 anatomical sciences educators. The questionnaire consisted of 50 items (open and multiple choice) for gross anatomy, microscopic anatomy, neuroanatomy, and embryology courses in medical schools across Mexico. A clinical approach was the most common course approach in all disciplines. Contact course hours and laboratory hours were higher in Mexican anatomy education compared to other countries, with the highest reported contact hours for embryology (133.4 ± 44.1) and histology (125 ± 33.2). There were similar contact hours to other countries for gross anatomy (228.5 ± 60.5). Neuroanatomy course hours (43.9 ± 13.1) were less than reported by the United States and similar to Saudi Arabia and higher than the United Kingdom. Dissection and microscopy with histological slides predominate as the most common laboratory activities. Traditional methods prevail in most of the courses in Mexico and only a few educators have implemented innovative and technological tools. Implementation of new methods, approaches, and curricular changes are needed to enhance anatomical sciences education in Mexico. 相似文献

Despite calls for more attention to the preparation of those who prepare teachers, there have been few examples of institutionally sanctioned and structured learning opportunities created to equip faculty with the knowledge and skills necessary to become effective teacher educators. In this paper, we describe a cross-disciplinary and collaborative initiative that involves shadowing of colleagues as a means of supporting the professional learning of science teacher educators. We illustrate the unique affordance of this model and highlight our professional learning across multiple dimensions: cognitive, practical, relational, and emotional. We illustrate how shadowing can support the learning of faculty at different career stages and from different disciplinary backgrounds and entry points to teacher education through a series of vignettes of shadowing in a variety of course contexts. Finally, we offer considerations for the transferability of our model to other institutions and contexts, and how further research conducted in the context of shadowing could help deepen our understanding of the knowledge base of science teacher educators and how this knowledge is developed.

This article examines the ways a social networking site for language learning (SNSLL) enhances or hinders intercultural communicative competence (ICC). The study identifies the components of intercultural competence that emerge from students’ interactions and reflections about the SNSLL Livemocha. The research was conducted with second-year students of an English class in a Colombian university. Data were collected through screen recordings, students’ logs, surveys, and a focus group. Findings indicate that, of the five dimensions of ICC, the components of Attitudes, Knowledge, Skills of Interpreting and Relating, and Skills of Discovery and Interaction featured strongly on students’ exchanges and reflections. SNSLLs hold potential to enhance intercultural skills; however, pedagogical adjustment and refocusing of some of their activities are required to expand opportunities for intercultural engagement. 相似文献

The purpose of this study was to analyse the effect of players’ dismissals on the outcome of attacks in elite futsal matches, and to establish the performance profile of the attacks made in numerical superiority by elite futsal teams. One hundred and twenty five attacking game situations in numerical superiority (dismissal of opponents from defensive team) were analysed from the regular season of the Spanish professional Futsal League. The effect of contextual-related variables (quality of opposition, match-location, match-periods, opponent team’s fouls, match-status, attack-duration and match-type) on goal effectiveness was analysed using binomial logistic regression and two-step cluster analysis. Results from the binary logistic regression showed that the highest attack effectiveness was achieved when the teams play at home, perform the attack during minutes 33–36 and the opposing team has 3 fouls. Secondly, the two-step cluster analysis technique allowed identifying four types of attacks when the teams were playing with numerical superiority. The results showed the great importance (in order) of match-type, match-status, attacking team’s fouls, match-period, quality of opposition, opposing team’s fouls, match-location, goal situation, and attack duration. The identified trends may help coaches to design the superiority/inferiority scenarios more specifically during training and to monitor them during competition. 相似文献

Purpose: The aim of the present study was to determine which of the published anthropometric equations is the most appropriate to estimate body-fat percentage (BF%) in adolescent swimmers. Method: Eighty-eight swimmers (45 boys, 43 girls) participated in this study. Following the recommendations of the International Society of the Advancement of Kinanthropometry, biceps, triceps, subscapular, iliac-crest, supraspinale, front-thigh, and medial calf skinfold thicknesses were measured. Waist, hip, midthigh, calf, relaxed arm, and arm flexed and tensed girths were also registered. BF% was measured with dual-energy X-ray absorptiometry (DXA) to obtain the reference value. Existing anthropometric equations were applied, and BF% results obtained from anthropometric equations were compared to DXA BF% results with the modified Bland-Altman. Results: The Flavel, Durnin-Rahaman-Siri, and Durnin-Rahaman-Brozek were the only equations that did not demonstrate statistically significant differences when compared with DXA. Conclusion: The present study showed that the best anthropometric equation from existing literature to estimate BF% in swimmers is that proposed by Durnin-Rahaman (independently of applying the Siri or Brozek equation). 相似文献

This study aimed to (1) assess the reliability of the force, velocity, and power output variables measured by a force plate and a linear velocity transducer (LVT) for both the unconstrained and constrained loaded countermovement jump (CMJ), and (2) examine the effect of both the CMJ type and the measurement method on the magnitudes of the same variables. Twenty-three men were tested on the free CMJ and the CMJ constrained by a Smith machine. Maximum values of force, velocity, and power were recorded by a force plate and by a LVT attached to a bar loaded by 17, 30, 45, 60, and 75 kg. The reliability of all mechanical variables proved to be high (ICC > 0.70; CV < 10%) and similar for two CMJ types. However, force plate-derived measures displayed greater reliability than the LVT. The LVT also markedly overestimated the magnitudes of the mechanical variables, particularly at lower external loads. Therefore, although both jump types and both methods could be acceptable for routine testing, we recommend the force platform due to a higher reliability and more accurate magnitudes of the obtained variables. The unconstrained loaded CMJ could also be recommended due to the simpler equipment needed. 相似文献
