Abstract To determine the energy cost of low impact aerobic dance while varying arm movement height and the use of hand weights, 10 adults volunteered to participate in four choreographed trials. All trials consisted of identical leg movements. Arm movements, however, were performed above shoulder level both with and without 0.9-kg hand weights and below shoulder level both with and without 0.9-kg hand weights. Open circuit spirometry was employed throughout the 10-min videotape guided trials, and heart rate was measured by telemetry. Neither the use of hand weights nor the change in arm position height significantly altered the energy cost of low impact aerobic dance. However, heart rate responses were significantly different. Caution should be observed by aerobics instructors and participants as to the use of heart rate as an indicator of intensity for low impact aerobic dance. 相似文献

When conducting longitudinal research, the investigation of between-individual differences in patterns of within-individual change can provide important insights. In this article, we use simulation methods to investigate the performance of a model-based exploratory data mining technique—structural equation model trees (SEM trees; Brandmaier, Oertzen, McArdle, & Lindenberger, 2013)—as a tool for detecting population heterogeneity. We use a latent-change score model as a data generation model and manipulate the precision of the information provided by a covariate about the true latent profile as well as other factors, including sample size, under the possible influences of model misspecifications. Simulation results show that, compared with latent growth curve mixture models, SEM trees might be very sensitive to model misspecification in estimating the number of classes. This can be attributed to the lower statistical power in identifying classes, resulting from smaller differences of parameters prescribed by the template model between classes. 相似文献

ABSTRACTFirst-generation students are often described as disadvantaged in university adjustment, self-efficacy and grades. Yet this deficit model of understanding first-generation students ignores their cultural capital, which could increase resilience and resourcefulness. Here, 844 students (31% first-generation) in South Africa and Canada completed measures of resilience, resourcefulness, university adjustment, academic self-efficacy and self-reported grades. Overall, the results reveal that the characterisation of first-generation students is culturally specific and, in some ways, differs between Canada and South Africa. That is, the deficit model may better describe Canadian than South African first-generation students. Yet, in many ways first-generation students are like their peers and their academic outcomes are predicted by their culturally specific levels of resourcefulness and resilience. This study support the notion that the positives students bring to university should be considered and that students would benefit from being taught the requisite skills involved in increasing resourcefulness and resilience. 相似文献

Teachers’ positive attitude is most critically and consistently associated with successful inclusion. However, little is known about teachers’ first-hand encounters with inclusive education in Singapore. We present findings from a qualitative study on inclusion based on focus group interviews with 202 teachers from 41 resourced primary schools. The data were transcribed and coded using Interpretive Phenomenological Analysis and NVIVO software. Two broad clusters identified were teachers’ positive and negative experiences in implementing inclusion. More reference was made to negative than positive experiences. The most dominant negative experience was stress from challenging behaviours and instructional difficulties of catering adequately for diverse needs in the same classroom. The most salient positive experience was satisfaction with pupils’ progress and new learning for teachers. Classroom practices that facilitated inclusion and the value of training in shaping teachers’ attitudes towards inclusion were highlighted. 相似文献

This paper investigates children's use of converging obliques in their drawings of objects. Adults and adolescents, as well as 7‐year‐old children, were not very successful in using converging obliques in their drawings of small‐scale objects; they tended to use parallel edges. When confronted with the apparent convergence of a real road receding into the distance adults and adolescents switched to using converging obliques; 7‐year‐olds still drew parallel roadsides. Children were induced to use converging obliques, however, when asked to copy from a line drawing of a road or from a photograph, particularly when the convergence of the road in the photograph was more dramatic. 相似文献

The research described in this article is a case study of a fifth grade teacher's (Melissa) efforts to construct a teaching
and learning environment within her science teaching. Qualitative research methods were used to examine and analyze Melissa's
science teaching practice. Drawing from socio-cultural theories, I argue that her teaching and learning environment was constructed
as a form of mediated action through which she articulated and transformed the context, meaning, and action of her science
teaching. In particular, she forged links between a number of factors, such as historically recognizable forms of pedagogy,
perceptions of her students' socio-economic positions, knowledge of appropriate science teaching, and her experiences in a
preservice teacher education program. Through her pedagogical work, the teaching and learning environment was articulated
into a complex network of meanings, physical spaces, and concrete actions in which each element transformed the other. I suggest
that mediated action is a form of transformation that constitutes context, meaning, and action into a dynamic and constantly-shifting
teaching and learning environment.

5‐year‐olds, 7‐year‐olds and 9‐year‐olds were asked to draw three figures, one standing still and facing them, one standing still in profile and one running in profile. Half drew from imagination and half drew from models. The 5‐year‐olds made fewest distinctions in the way they drew the figures, the most notable being the greater spread of the legs of the running figure. With increasing age, more features were used to differentiate the three figures. There was little evidence of 5‐year‐olds adapting their figures in the presence of a model. Only among the older children was there a significant effect of the presence of a model when the 7‐year‐olds and, to a greater extent, the 9‐year‐olds drew their running figure with bent arms and legs and also with more transparencies and partial occlusions. 相似文献

Relationally and physically aggressive children's intent attributions and feelings of distress for relational and instrumental peer provocations 总被引:13,自引:0,他引:13
Numerous studies have demonstrated that physically aggressive children exhibit hostile attributional biases in response to instrumental peer provocations, a social information-processing pattern that has been recognized as a contributor to peer-directed aggression. The present studies (N = 127 and N = 535) were designed to extend past research by evaluating the intent attributions and feelings of emotional distress of relationally and physically aggressive children in response to instrumental and relational provocation contexts. Results indicated that physically aggressive children exhibited hostile attributional biases and reported relatively greater distress for instrumental provocation situations, whereas relationally aggressive children exhibited hostile attributional biases and reported relatively greater distress for relational provocation contexts. Implications of these findings for the understanding of factors that may contribute to relational as well as physical aggression are discussed. 相似文献

At the heart of all curriculum decision-making is the learner. Contemporary early childhood education theory and practice emphasises young children’s agency and voice in their learning paying particular attention to valuing each child’s sociocultural contexts. As learners, children are considered capable and active participants rather than as deficit and passive recipients. How does the implementation of godly play in prior-to-school and school early years settings sit within a contemporary view of childhood? To what extent does this programme align with early childhood theory and practice? This paper seeks to evaluate the presence and place of godly play (which is not a curriculum and nor does it claim to be a curriculum) in the religiously affiliated early childhood education context in either prior-to-school or school settings. It is to be emphasised that this paper is not evaluating the presence and place of godly play in the faith community of the local parish where all who participate are believers coming together to share that faith and to have that faith strengthened. However, its presence and place in formal educational settings outside of parish faith communities is questionable and requires closer critique. 相似文献
