This study investigated whether the associations between parental distress with conduct problems (CPs) and prosocial behaviors (PBs) are moderated by children's skin conductance (SC) and heart rate (HR) reactivity to fear. Participants were 147 Greek-Cypriot children (Mage = 7.30, 44.2% girls), selected from a larger screening sample (data were collected from 2015 to 2018). Longitudinal associations suggested that children with high HR reactivity to fear were more likely to display PB, whereas those with low SC reactivity were more likely to engage in CP behaviors. In contrast, interaction effects suggested that children high on SC reactivity to fear were more susceptible to the effects of parental distress, as indicated by their higher vulnerability to engage in CP (cross-sectionally) behaviors and their lower scores on PB (cross-sectionally and longitudinally). 相似文献

Repeated-sprint training often involves short sprints separated by inadequate recovery intervals. The effects of interval duration on metabolic and performance parameters are unclear. We compared the effects of two training programmes, differing in rest interval duration, on muscle (vastus lateralis) metabolism and sprint performance. Sixteen men trained three times a week for 8 weeks, each training session comprising 2-3 sets of two 80-m sprints. Sprints were separated by 10 s (n = 8) or 1 min (n = 8). Both training programmes improved performance in the 100-, 200-, and 300-m sprints, but the improvement was greater in the 10-s group during the final 100 m of the 200- and 300-m runs. Independent of interval duration, training mitigated the drop of muscle ATP after two 80-m sprints. The drop in phosphocreatine and the increases in glucose-6-phosphate and fructose-6-phosphate after two 80-m sprints were greater in the 10-s group. In conclusion, training with a limited number of repeated short sprints (≤10 s) may be more effective in improving speed maintenance in 200- and 300-m runs when performed with a 1:1 rather than a 1:6 exercise-to-rest ratio. This may be due to a greater activation of glycolysis caused, in part, by the limited resynthesis of phosphocreatine during the very short rest interval. 相似文献

The person-fit literature assumes that aberrant response patterns could be a sign of person mismeasurement, but this assumption has rarely, if ever, been empirically investigated before. We explore the validity of test responses and measures of 10-year-old examinees whose response patterns on a commercial standardized paper-and-pencil mathematics test were flagged as aberrant. Validity evidence was collected through postexamination reflective interviews with 31 of the 80 pupils flagged as aberrant and their teachers, and teacher assessment (TA) judgments for the whole examination cohort of 674 examinees. Analysis suggested that interview-adjusted scores were significantly better fitting than expected by chance, but only some adjustments suggest serious mismeasurement. In addition, disagreement between TA and test scores was significantly greater for aberrant examinees, and partially predicted the interview adjustments. We conclude that person misfit statistics when combined with TA might be a useful antidote to mismeasurement, and we discuss the implications for assessment research and practice. 相似文献

This article focuses on the implementation of the Professional Learning through Reflection promoted by Feedback and Coaching (PROFLEC) project in Cyprus. The project aimed to provide valid and reliable feedback to school leaders and support them to interpret this into meaningful practice. A three-step-process, involving a self-assessment inventory and individualized feedback reports, workshops, and coaching sessions was employed. Results suggest that feedback and coaching can be effective learning strategies in school leaders’ professional development programmes. Findings are discussed in light of the potential of these two strategies for future developments of such programmes within the particular setting. 相似文献

AbstractSince a significant percentage of students facing the risk of school failure, educational systems struggle to improve equity in education. Researchers argue that the missing link in establishing educational equity is parental involvement (PI). Τhis study examines three dimensions of PI (home-based, school-based, parental dispositions) as to effects on risk for school failure across two competencies (language and mathematics), while controlling for other variables, e.g. prior achievement and demographic factors. Data is drawn from the national ‘Program for Functional Literacy’ involving 6865 Year 6 students from 226 Cyprus public primary schools. Logistic multilevel modeling analyses, with students nested within schools, lead to interesting findings. Parental dispositions appear to relate significantly to the risk for failure in language and mathematics, confirming that this dimension holds the strongest impact. In addition, from the home-based PI dimension, the availability and number of books at home have statistically consistent effects on the risk across both competencies. Other dimensions or components of these dimensions relate significantly to risk for one competency only. These findings are further discussed in the context of future policy and research directions. 相似文献

Deaf children have been integrated into secondary schools in Cyprus since 1990. This article reports the results of a major study carried out in Cyprus, the aim of which was to evaluate for the first time the support services available for deaf children receiving their education in secondary general schools. For the purposes of our study, four types of questionnaires were designed and administered to all deaf children integrated into secondary general schools, as well as to their parents, teachers, and head teachers. All participants stressed that the support services are vital for the children's academic success and social integration. The main support services identified by the participants in our study were: one-to-one and group sessions; presence of co-coordinators (special teachers of the deaf); "acoustical treatment" of the classrooms; provision and management of personal amplification, psychological support, and counseling; and in-service training for designated teachers. The majority of the participants expressed satisfaction with the support services offered to them. They also made some suggestions for the improvement of the integration of deaf children into secondary schools in Cyprus. 相似文献

Researchers have developed indices to identify persons whose test results ‘misfit’ and are considered statistically ‘aberrant’ or ‘unexpected’ and whose measures are consequently potentially invalid, drawing the test’s validity into question. This study draws on interviews of pupils and their teachers, using a sample of 31 10‐year‐olds who were flagged as most ‘aberrant’ in a standardised mathematics test. The children’s and their teachers’ explanations were analysed and attributed: (i) to item‐, person‐ (self/other) and classroom‐levels; and ii) according to causal dimensions. Children’s and teachers’ explanations were mostly in agreement in relation to unexpected negative results and they included references to previously well‐cited sources of construct‐irrelevant variance (e.g. ineffective test‐taking strategies, careless mistakes) as well as construct‐relevant variance (e.g. misconceptions, weaknesses in particular topics). Findings of this exploratory study are discussed from a test validity and attribution theory perspective: we conclude that this approach offers grounds for multi‐level explanations of person misfit and that this qualitative research approach to unexpected responses is worthy of more attention. 相似文献

Hypotheses about aberrant test-response behavior and hence invalid person-measurement have hitherto included factors like ability, gender, language, test-anxiety, and motivation, but these have not previously been collectively investigated with real data, or with multilevel models. This study analyzes the effect of these factors on person aberrance using a real mathematics assessment data set under the framework of a two-level (person and classroom) hierarchical model. The results suggest that higher-scoring pupils, and, to a lesser extent, second-language learners are significantly more often aberrant. But more importantly, we find that the classroom makes a significant contribution to person aberrance and conclude that studies that investigate the sources of person aberrance with real data should model the classroom as well as individual levels. 相似文献

Self-efficacy is extensively discussed within social cognitive theory. This study aimed to explore the impact of professional development and practice on school leaders’ self-efficacy in Cyprus. A quasi-experimental design involving 2 groups of novice secondary deputy head teachers was employed. All participants practised leadership at the time, but the experimental group also attended a leadership training programme. The School Leaders’ Self-Efficacy Scale addressing 8 dimensions was distributed to both groups at the beginning and the end of the school year. A within-group analysis indicated positive effects on self-efficacy regarding evaluating classroom practices for the experimental group. However, for the control group, effects were negative on self-efficacy with regards to evaluating classroom practices, monitoring learning, and leadership of continuing professional development. Between-group analyses revealed positive gains for the experimental group across the 3 aforementioned self-efficacy dimensions. Arising implications are discussed in the context of professional development programmes for school leaders in Cyprus. 相似文献
