AbstractUniversity rankings are increasingly important internationally, and in the UK include a sustainability ‘Green League’. However, there is little evidence about experiences of studying in ‘sustainable universities’. We report an empirical study at five universities in varied positions in the Green League, exploring students’ energy literacy, environmental attitudes and perceptions of their institution’s energy-saving efforts. Although the link to energy literacy is not clear, findings suggest that there are significant differences between students’ environmental attitudes at universities placed at different points in the league. In addition, students at higher ranked universities are more positive about their university’s energy-saving efforts, suggesting that these institutions may exhibit more overt manifestations of sustainability. This is important since students report being more likely to choose energy-conservation behaviours if there is visible representation of energy use. The study is the first to attempt a comparison between universities at different positions in a sustainability ranking. 相似文献

A pool of 116 14-18-year-old secondary school pupils who had been given the computer-presented Cognitive Styles Analysis was used to provide two sub-samples to explore the relationship between style and motor skills and sports performance. The Motor Skills sub-sample of 69 (32 males and 37 females) did a battery of motor skills tests. A factor analysis suggested four skills factors - bodily movement, interactive skills, mechanical skills and aiming. All of these except the mechanical skills showed a significant relationship to style. The Sports Performance sub-sample of 99 (46 males and 53 females) were rated on a five-point scale by their teachers on performance in rugby, soccer and cricket for the boys, and hockey, netball and tennis for the girls. Here, there was a significant effect of style for tennis but not for the team games. The findings were discussed in terms of their practical implications. 相似文献

The development of online and virtual teaching and learning environments to augment formal face-to-face environments raises questions about the way the new communication and information technologies (CITs) are being incorporated into the on-campus environment. More importantly, this development challenges the meaning of the on-campus student learning experience. The new CITs require institutions, teachers and researchers to reconsider the relationship of the physical setting to the student learning experience. This paper highlights examples of recent developments of new learning environments which have been enhanced by the contribution of educational developers at several Australian universities. It also proposes a set of pedagogically informed principles to guide the development of on-campus teaching and learning environments which may feature the use of CITs. 相似文献

Adolescent success providing satisfying support in response to a close friend's call in a caregiving task was examined as a potentially fundamental developmental competence likely to predict future social functioning, adult caregiving security, and physical health. Adolescents (86 males, 98 females; 58% White, 29% African American, 8% mixed race/ethnicity, 5% other) were followed from ages 13 to 33 (1998–2021) using multiple methods and reporters. Early caregiving success was found to predict greater self- and partner-reported caregiving security, lower negativity in adult relationships, and higher adult vagal tone. Results are interpreted as advancing our understanding beyond simply recognizing that adolescent friendships have long-term import, to now identifying specific capacities within friendships that are linked to longer-term outcomes. 相似文献

Gill, P. E. 1976. The Relationship Between Mental Ability and Eight Background Variables. Scand. J. educ. Res. 20, 135‐145. Multiple regression is seen as a search technique when applied to IQ. test data. The results from such a search are stochastic rather than deterministic. Because of this it is imperative that comprehensive samples be studied. The sample in this study (n = 3,695) was representative of the population of Irish 6‐ to 12‐year‐olds. The results are surprising in that the total variance explained by predictors such as SES, sex, family size, position in family, absenteeism and urbanity is never more than 8 %. Differences in how predictors behave with IQ and Vocabulary are noted. SES, family size and urbanity are the most significant predictors. When Vocabulary is the criterion, sex differences (in favour of girls) emerge consistently. It is contended that pupils of low intelligence go absent more often than their peers. The total variance explained was increased when homoscedasticity was reduced by stabilizing criterion variance (by reducing age span). 相似文献

This paper reports an investigation into Australian primary school teachers’ knowledge and confidence for mental health promotion. Questionnaires were delivered to 1397 teachers. In-depth interviews were held with 37 teachers. Quantitative results showed that half to two thirds of teachers felt efficacious and knowledgeable about selected components of mental health promotion. Independent judgments by staff about students’ mental health status concurred with students’ scores on the Strengths and Difficulties Questionnaire in about 75% of cases, indicating a good level of staff awareness about students’ mental health status. Exposure to the KidsMatter Primary mental health promotion initiative was associated with improvements in teachers’ efficacy, knowledge and pedagogy, with small to medium effect sizes. Qualitative analysis indicated that teachers’ subject-matter and pedagogical knowledge were heavily reliant on curriculum resources. Implications of the findings for the implementation of school-based mental health promotion initiatives are discussed. 相似文献

Findings are presented from the first randomized control trial of the effects of encouraging symbolic gesture (or “baby sign”) on infant language, following 40 infants from age 8 months to 20 months. Half of the mothers were trained to model a target set of gestures to their infants. Frequent measures were taken of infant language development and dyadic interactions were scrutinized to assess mind‐mindedness. Infants exposed to gesture did not differ from control conditions on language outcomes; thus, no support was found for previous claims that encouraging gesturing with infants accelerates linguistic development. Microgenetic analysis revealed mothers in the gesture training conditions were more responsive to their infants' nonverbal cues and encouraged more independent action by their infant. 相似文献

Teachers can help minority children close the academic achievement gap in intermediate and middle school by combining literacy instruction and content-area material. This connection improves reading achievement and increases curriculum knowledge, even if students have previously experienced difficulty with primary school reading. Fortunately, upper-elementary and middle-level learners are still naturally curious, are developing cognitively, and have acquired some basic reading skills. Teachers can therefore extend students' previous learning by using a spiral curriculum, in which curricular concepts are introduced at an appropriate level and then revisited at more challenging levels. Teachers can also increase the academic complexity for students by using strategies that include picture books, word recognition skills, intensive subject matter, vocabulary in a meaningful context, Readers Theater, and after-school activities. 相似文献

The Trolley Problem as defined in this paper is a series, or continuation, of increasingly difficult ethical riddles successfully implemented in a classroom environment to spur complex, critical thinking and dialogue. The activity is designed upon the scenario of a runaway train with different and challenging choices, segueing neatly into group discussions of ethics while limiting potential disruptions or controversies. It fits nicely with multiple standards, goals and/or outcomes and can be accommodated to multiple grade levels and courses. It is a powerful, yet easily implemented classroom exercise for educators to develop higher order thinking and dialogue for their students. 相似文献
