A number of recent studies have revealed that taking part in a sail-training-based Adventure Education Programme elevates youths’ self-esteem. Across two studies, we sought to examine the extent to which youths’ sense of belonging contributed to this increase in self-esteem. Study 1 revealed that participants who completed the voyage showed an increase in self-esteem from the first to the last day of the voyage. Partial correlation revealed that group belonging made a unique contribution to this change. Study 2 replicated Study 1 and, further, demonstrated that the relationship between group belonging and self-esteem was not a function of self-efficacy or group esteem. Such findings suggest that an important contributing factor to the benefits of sail-training interventions is their potential to satisfy psychological needs, in this case the need to belong.  相似文献

Purpose: Correlations between fatigue-induced changes in exercise performance and maximal rate of heart rate (HR) increase (rHRI) may be affected by exercise intensity during assessment. This study evaluated the sensitivity of rHRI for tracking performance when assessed at varying exercise intensities. Method: Performance (time to complete a 5-km treadmill time-trial [5TTT]) and rHRI were assessed in 15 male runners following 1 week of light training, 2 weeks of heavy training (HT), and a 10-day taper (T). Maximal rate of HR increase (measured in bpm·s?1) was the first derivative maximum of a sigmoidal curve fit to HR data recorded during 5 min of running at 8 km·h?1 (rHRI8km·h?1), and during subsequent transition to 13 km·h?1 (rHRI8–13km·h?1) for a further 5 min. Results: Time to complete a 5-km treadmill time-trial was likely slower following HT (effect size ± 90% confidence interval = 0.16 ± 0.06), and almost certainly faster following T (–0.34 ± 0.08). Maximal rate of HR increase during 5 min of running at 8 km·h?1 and rHRI8–13km·h?1 were unchanged following HT and likely increased following T (0.77 ± 0.45 and 0.66 ± 0.62, respectively). A moderate within-individual correlation was found between 5TTT and rHRI8km·h?1 (r value ± 90% confidence interval = –.35 ± .32). However, in a subgroup of athletes (= 7) who were almost certainly slower to complete the 5TTT (4.22 ± 0.88), larger correlations were found between the 5TTT and rHRI8km·h?1 (r = –.84 ± .22) and rHRI8–13km·h?1 (r = –.52 ± .41). Steady-state HR during rHRI assessment in this group was very likely greater than in the faster subgroup (≥ 1.34 ± 0.86). Conclusion(s): The 5TTT performance was tracked by both rHRI8km·h?1 and rHRI8–13km·h?1. Correlations between rHRI and performance were stronger in a subgroup of athletes who exhibited a slower 5TTT. Individualized workloads during rHRI assessment may be required to account for varying levels of physical conditioning.  相似文献

This study uses meta-analysis to compare the persuasive effects of metaphorical and literal messages and assess various theoretical explanations for the relatively greater persuasiveness of metaphor. The meta-analysis includes studies from 2001 to 2015 that use various message formats and topics. Results indicate an overall effect size of r = 0.09, p < .001, 95% CI [0.06, 0.12], which supports the conclusion that metaphorical messages are more persuasive than literal messages. Moderator analyses indicate differences in effect sizes based on metaphor target familiarity, message topic, and message format. A meta-regression using the theoretical moderators indicates that message format was the strongest predictor of variation in effect size. This study provides implications related to the theoretical mechanism behind the greater persuasive effects of metaphor.  相似文献

The potential of pictorial and verbal metaphors to gain attention and enhance persuasion is considerable. Few scholars, however, have investigated the persuasive effects of metaphor in health messages. We applied a 2 × 2 factorial experiment to examine the effects of metaphor use (metaphor/literal) and message format (verbal/pictorial) on cognitive processing and persuasive outcomes of condom promotion messages. Results showed no significant differences in cognitive processing according to metaphor or format, but there were differences in attitudes and behavioral intentions according to metaphor and format, with literal and verbal messages performing best. Potential explanations for findings and implications for future research and health message design are discussed.  相似文献

ABSTRACT— Teaching others effectively may rely on knowledge about the mind as well as self-control processes. The goal of this investigation was to explore the role of theory of mind (ToM) and executive function (EF) in children's developing teaching skills. Children 3.5–5.5 years of age ( N = 82) were asked to teach a confederate learner how to play a board game and were administered multitask batteries of ToM and EF with mental age, sex, and memory capacity as controls. There was a developmental increase in children's teaching skills (e.g., older children taught longer, explained more rules, and used more strategies when teaching). Examined separately, both ToM and EF explained unique variance in teaching skills over and above controls. Taken together, EF was a significant predictor of teaching efficacy over and above ToM and controls, whereas the same did not hold true for ToM. These results suggest that ToM may be a necessary prerequisite for teaching to occur; however, EF skills appear to play a vital role in children's teaching efficacy.  相似文献

Educational leadership/management scholars have undertaken work which documents the difficulties particular headteachers face when implementing policy. Some have suggested that headteachers mediate policy, ensuring the best possible outcomes for their schools, but there is also critique of this argument and a counter‐suggestion that heads ought to resist the imposts of conservative, marketised policies which produce and reproduce educational inequities. In this article I consider this position, and argue that if the field is to take up the question of resistance then it will need to extend its theoretical resources, interrogate and test out the limits of the proposition through empirical example, consider instances where resistance appears to occur, and move beyond a focus on individual headteachers to take seriously their collective professional organisations. In making this argument, I generate some suggestions for future research.  相似文献

Science as profession is generally defined narrowly as research. Science education as preparation for a profession in research is usually perceived as course work and laboratory training, even though the necessary knowledge and skills to pursue a research career are more extensive and diverse and are learned in one-on-one interaction with mentors. A complete education of science professionals includes the values, ethical standards and conventions of the discipline since they are fundamental to the profession. Mentoring and education in the responsible conduct and reporting of research and in the ethical dimensions of science are among the professional responsibilities of scientists and need to be discussed as part of science education. Moreover, science as an enterprise is much more than research and includes a number of other components, including science teaching, science journalism, and science policy. Each of these contributes to the nature of science and its role in society.  相似文献

Abstract

The purpose of this study was to compare the long-term effects of 2 first-grade Response to Intervention (RTI) models (Dynamic and Typical RTI) on the reading performance of students in second and third grade. Participants included 419 first-grade students (352 in second grade and 278 in third grade after attrition). Students were classified based on first-grade screeners as at risk or not at risk and then based on their RTI (no risk [NR], relative easy to remediate [ER], and requiring sustained remediation [SR]). Students in the dynamic RTI condition had higher reading comprehension scores at the end of third grade. At the end of second grade, ER and SR students had lower reading scores than NR students. At the end of third grade, there were no differences in reading skills between ER and NR students, but SR students had lower scores than NR students. ER students in the dynamic RTI condition had higher reading scores at the end of second grade than those in the typical RTI condition. Limitations and directions for future research are discussed.  相似文献
