The present study examines the role of orthographic complexity on Italian children’s word reading. Two experiments are reported in which elementary school children (3rd and 5th graders) read aloud words containing simple or contextual letter-sound conversion rules. In Experiment 1, both groups of participants read words containing contextual rules more slowly and less accurately than words containing simple, non-contextual rules. Experiment 2 showed that the effect of rule complexity held for low but not high frequency words, on both reading speed and accuracy. No interactions with grade were found. This pattern is in line with previous findings on the effects of rule contextuality on adult performance [Burani, C. Barca, L. & Ellis, A. W. (2006). Psychonomic Bulletin & Review, 13, 346–352]. Despite the regularity of the Italian orthography, the presence of complex rules influences both reading speed and accuracy of young readers. Moreover, the reading system of readers of a shallow orthography seems efficient from the first years of reading instruction.  相似文献

We conducted a meta-analysis to investigate the effectiveness of interventions aimed at reducing teacher burnout. Online and reference list searches yielded 513 unique results, and the final sample contains 23 controlled trials (19 journal articles and 4 unpublished dissertations). More than two thirds of the studies had optimal quality, and the risk of bias was not related to the overall effectiveness of the interventions. The overall effects were small, but statistically significant (d = 0.18, SE = 0.05, Z = 3.26, p < 0.001, k = 23). Separate analyses on each burnout component showed similar intervention effects on emotional exhaustion and personal accomplishment, but almost null effects on depersonalization (d = 0.03, SE = 0.06, Z = 0.53, p > 0.05, k = 11). Additional moderator analyses suggested that mindfulness interventions had significant effects on exhaustion and personal accomplishment. Interventions on primary and middle school teachers reported effect sizes below the average effect. Similar to previous findings, interventions that lasted less than 1 month had the smallest levels of efficacy.  相似文献

The creation and the achievements of the Virtual University of Monterrey Tech (Instituto Tecnolo´gico y de Estudios Superiores de Monterrey) in Mexico are briefly described. Monterrey Tech itself, which was founded in 1943, has had a vocation going back a number of years to offer distance education on a number of satellite campuses. The Virtual University was founded in 1996 to carry on the distance education vocation of the institution as a whole in Mexico and in other Latin American countries with the use of the new information and communications technologies (ICTs). The Virtual University is particularly active in the domain of community education, teacher retraining, in-company training programmes, and in the offer of training for Mexican state and local officials. Although a private entity, the Virtual University and its parent organization, Monterrey Tech, are firmly committed to the public development of Mexico.  相似文献

Peer Observation of Teaching has raised a lot of interest as a device for quality enhancement of teaching. While much research has focused on its models, implementation schemes and feedback to the observed, little attention has been paid to what the observer actually sees and can learn from the observation. A multidisciplinary peer observation of teaching program is described, and its data is used to identify the pedagogical aspects to which lecturers pay more attention to when observing classes. The discussion addresses the valuable learning opportunities for observers provided by this program, as well as its usefulness in disseminating, sharing and clarifying quality teaching practices. The need for further research concerning teacher-student relationships and students’ engagement is also suggested.  相似文献

The article investigates the relations between the technological innovation and the usage done, in particular but not exclusively, by the young generation in Italy: the basis for the analysis will be the results of the 2008 edition of the Permanent Observatory on Digital Content. Moreover it presents an overview on how the use of technologies affects the consumption of cultural and entertainment content. It highlights that there is a strong relationship among the level of consumption of these kind of goods and the way technologies are used and, more in particular, shows how the more advanced use of the technologies is depending, more than from the frequency or regularity, from the level of awareness in their use, deriving in general by a strong knowledge and skill, and, especially by the consumption done by the users of the cultural and entertainment goods. The research shows two different clusters of innovative users of technologies: Technofan and Eclectic with very different habits.

Supervised exercise has shown benefits for subjects with asthma, but little is known about the effectiveness of unsupervised physical activity on this population. We investigated the effects of a 12-week unsupervised pedometer-based physical activity program on daily steps and on clinical and psychological parameters of adults with asthma. Clinically stable adults with moderate to severe asthma were encouraged to take daily 30-minute walks and were randomized to pedometer and control groups. The pedometer group received pedometers and individualized daily step targets. Changes in daily steps (average of steps taken during six consecutive days), six-minute walk test (6MWT), health-related quality of life, asthma control and anxiety and depression levels were assessed 12 weeks after intervention and 24–28 weeks after randomization. Thirty-seven participants were recruited and 30 completed the intervention. At 12 weeks, the groups differed significantly in daily steps (adjusted average difference, 2488 steps; 95% confidence interval [CI], 803 to 4172; p = 0.005) and in the 6MWT (adjusted average difference, 21.9 m; 95% CI, 6.6 to 37.3; p = 0.006). These differences were not significant 24–28 weeks after randomization. The program was effective in increasing daily steps of adults with moderate to severe asthma 12 weeks after intervention.  相似文献

This study was conducted to determine the effects of inspiratory muscle training (IMT) on respiratory and peripheral muscles oxygenation during a maximal exercise tolerance test and on repeated-sprint ability (RSA) performance in professional women football players. Eighteen athletes were randomly assigned to one of the following groups: SHAM (n = 8) or IMT (n = 10). After a maximal incremental exercise test, all participants performed (on a different day) a time-to-exhaustion (Tlim) test. Peripheral and respiratory muscles oxygenation by near-infrared spectroscopy, breath-by-breath ventilatory and metabolic variables, and blood lactate concentration were measured. The RSA test was performed on a grass field. After a 6 week intervention, all athletes were reevaluated. Both groups showed increases in inspiratory muscles strength, exercise tolerance and RSA performance, however only the IMT group presented lower deoxyhemoglobin and total hemoglobin blood concentrations on intercostal muscles concomitantly to an increased oxyhemoglobin and total hemoglobin blood concentrations on vastus lateralis muscle during Tlim. In conclusion, these results may indicate the potential role of IMT to attenuate inspiratory muscles metaboreflex and consequently improve oxygen and blood supply to limb muscles during high-intensity exercise, with a potential impact on inspiratory muscle strength, exercise tolerance and sprints performance in professional women football players.  相似文献

Abstract

This study investigated the influence of the regression model and initial intensity during an incremental test on the relationship between the lactate threshold estimated by the maximal-deviation method and performance in elite-standard runners. Twenty-three well-trained runners completed a discontinuous incremental running test on a treadmill. Speed started at 9 km · h?1 and increased by 1.5 km · h?1 every 4 min until exhaustion, with a minute of recovery for blood collection. Lactate–speed data were fitted by exponential and polynomial models. The lactate threshold was determined for both models, using all the co-ordinates, excluding the first and excluding the first and second points. The exponential lactate threshold was greater than the polynomial equivalent in any co-ordinate condition (P < 0.001). For both models, the lactate threshold was lower when all co-ordinates were used than when the first and the first and second points were excluded (P < 0.001). 10-km race pace was correlated with both the exponential and polynomial lactate thresholds for all the co-ordinate conditions (r ≥ 0.75, < 0.001 and r ≥ 0.56, P < 0.05, respectively). The results suggest that the exponential lactate threshold should be used instead of the polynomial equivalent since it is more strongly associated with performance and is independent of the initial intensity of the test.  相似文献
