The aim of the this study was to establish age- and gender-specific physical fitness normative values and to compare percentiles and Z scores values in a large, nationwide sample of Greek children aged 6–18 years. From March 2014 to May 2014, a total of 424,328 boys and girls aged 6–18 years who attended school in Greece were enrolled. The studied sample was representative, in terms of age–sex distribution and geographical region. Physical fitness tests (i.e. 20?m shuttle run test (SRT), standing long jump, sit and reach, sit-ups, and 10?×?5?m SRT) were performed and used to calculate normative values, using the percentiles of the empirical distributions and the lambda, mu, and sigma statistical method. Normative values were presented as tabulated percentiles for five health-related fitness tests based on a large data set comprising 424,328 test performances. Boys typically scored higher than girls on cardiovascular endurance, muscular strength, muscular endurance, and speed/agility, but lower on flexibility (all p values <0.001). Older boys and girls had better performances than younger ones (p?相似文献

This study examined the relationship between adolescents’ attachment style and their decision to enter mentoring relationships. The participants were 569 Greek Cypriot high school students. It was found that adolescents who have a mentor are more secure in their attachment than those who do not. Girls with low scores in secure attachment do not enter easily into mentoring relationships. Older adolescents are more anxious in their attachments, probably because they can better appreciate the possible difficulties if something goes wrong; thus, they are more reluctant to take the risk of starting a mentoring relationship than younger students. Furthermore, secure attachment was found to be positively correlated to the perceived impact of the whole experience: the more secure the attachment, the stronger the mentoring bond seems to be. 相似文献

The present study investigated the direction of the relationship between parental rejection and children’s engagement in bullying and victimization. Using a cross-lagged design, we examined whether (a) bullying and victimization predict an increase in parental rejection six months later, (b) parental rejection predicts an increase in bullying and victimization six months later, and (c) there is a reciprocal association between bullying/victimization and parental rejection. The participants were 846 early adolescents (mean age = 12.63 years) randomly selected from primary and secondary schools in Cyprus and Greece (375 Cypriots, 471 Greek students) and their parents. Children completed a translated version of the Personal Experiences Checklist – (PECK) and the Rejection subscale of the Parental Acceptance/Rejection Questionnaire. The results showed that parental rejection at Time 1 predicted significantly victimization at Time 2. Parental rejection however, was not a significant predictor of bullying. Moreover, bullying and victimization at Time 1 predicted significantly parental rejection at Time 2. These results provide further insight at the theoretical level in as far our understanding of the familial dynamics in bullying victimization and may provide clinical implications in relation to counselling of victimized children and their parents. 相似文献

The purpose of this study was to use three-dimensional methods to determine whether there are distinct kinematic differences between sprint and distance front crawl swimmers when swimming at a sprint pace. Seven sprint and eight distance specialists performed four 25-m sprints through a 6.75-m(3) calibrated space recorded by six gen-locked cameras. The variables of interest were: average swim velocity, stroke length, stroke frequency, upper limb and foot displacement, elbow angle, shoulder and hip roll angles, duration of stroke phases, and the time corresponding to particular events within the stroke cycle relative to hand entry. Differences between sprint and distance swimmers were assessed with an independent t-test for each variable, in addition to effect size calculations. Differences between sprint and distance front crawl swimmers were generally small and not significant when swimming at a sprint pace. Differences were limited to temporal aspects of the stroke cycle. These findings suggest that coaches should not train sprint and distance specialists differently in terms of technique development. 相似文献

The aim of this study was to examine whether there are gender differences in actual maths achievement, in attitudes towards maths, and in relevant achievement attributions among early adolescents. The participants were 255 eighth grade students (mean age 14.2) from 10 randomly selected public junior high schools in Cyprus. They completed a questionnaire that measured their attributions of their own maths achievement and their attitudes towards the subject (how attractive and useful it is). Then they took a maths achievement test and immediately afterwards they reported their affective reactions towards the test (how challenging or threatening they thought it was). No significant differences were found between boys and girls in actual maths achievement. Significant differences were found, however, in the way the two genders explain their performance. Boys tend to believe more than girls do that their intellectual abilities are causing their high marks in maths. Also, it was found that high achievement could predict a positive attitude towards mathematics, but not vice versa. These findings contradict the widespread beliefs that (a) girls are not as good at maths as boys are; and (b) better attitudes towards maths lead to better performance. 相似文献

Beliefs of experienced and novice teachers about achievement 总被引：1，自引：0，他引：1

The aim of this study was to examine the beliefs that experienced and novice teachers hold about school achievement. It is important to investigate these beliefs and attributions because of the significant role that teachers play in the lives of most children. A group of Greek Cypriot elementary school teachers (n = 154) and a comparable group of teacher education students (n = 159) completed the Beliefs About School Achievement (BASA) scale. It was found that, in comparison to student teachers, experienced teachers tend to attribute achievement more to factors that are biologically determined, uncontrollable by the child, and stable over time – such as intellectual ability. They also believe significantly more than student teachers that factors such as gender and family background play an important role in child achievement. In contrast, novice teachers believe more in the role that teachers play in student learning and in the importance of student effort. 相似文献

Designing and deploying programming courses is undoubtedly a challenging task. In this paper, an attempt to analyze important aspects of a sequence of two courses on imperative-procedural and object-oriented programming in a non-CS majors Department is made. This analysis is based on a questionnaire filled in by fifty students in a voluntary basis. The issues of the programming courses that are investigated refer to: the strategy selected for the introduction to programming; the sequence of the programming techniques and languages taught and the transition from the one to the other; students’ difficulties with programming in general and with imperative-procedural and object-oriented programming in specific; the teaching and learning design of both courses; and the material that students rely on for learning programming. Based on the analysis of students’ replies on the questionnaire, related work and the instructor’s experience on teaching the courses, conclusions are drawn regarding all the aforementioned aspects of designing and deploying programming courses. The main contribution of the paper is the fact that all the important and interrelated aspects of a sequence of two programming courses are investigated in conjunction, providing realistic implications and guidelines for improving the quality and effectiveness of existing programming courses and designing and deploying new courses. The main results refer to the usage of a pseudo-language for an introduction to programming, the transition from procedural to object-oriented programming, the intrinsic difficulties of learning programming, and practices for a more successful teaching and learning design of programming courses. 相似文献

Abstract Young, healthy varsity swimmers were studied over a period of 14 months with regard to the effect of a typical training and competitive collegiate swimming program on plasma cholesterol and phospholipids. Chemical analyses on blood cholesterol and phospholipids were made and compared for competitive and noncompetitive seasons. A dietary analysis was also made during the competitive season. In both the original and subsequent study involving the current (1960–61) varsity swimmers analyses were made of the acute effect of physical exertion on plasma cholesterol and phospholipids. The exercise, used for conditioning varsity swimming athletes did not significantly lower blood cholesterol and phospholipids. However, this result is not necessarily at variance with the view of some investigators that exercise does exert a hypocholesterilizing effect. Several factors are discussed which are thought to have influenced ultimate results. 相似文献

The project My house of value was implemented at a fourth grade primary school classroom for 10-year-old students in Nicosia, Cyprus. The main goal of the project was to examine how pupils realise identity and diversity in their broad sense, how they deal with stereotypical thoughts and how they understand interaction in both positive and negative ways. This was achieved through certain activities during the art lesson, which gave them the opportunity to express themselves in various ways. The method included observation and discussion in classroom, analysis of teachers' diaries and students' works and interviews with students reflecting on the various activities of the project. The final results showed that many pupils could realise that the diversities between identities are more than similarities, but this fact was not necessarily negative. They also became aware of stereotypical thinking concerning the self and the other. They also realised the complication of human intercultural encounters since emotions and experiences are involved. Finally, they concluded that the different ways of knowing the other include different means of communication. The implementation of the project showed that such activities can have a positive impact on pupils especially if they are incorporated in everyday curriculum and classroom practice. 相似文献
