Broad‐band or multidimensional behavior‐rating scales are common tools for evaluating children. Two popular behavior‐rating scales, the Behavior Assessment System for Children, Second Edition (BASC‐2; Reynolds & Kamphaus, 2004) and the Child Behavior Checklist (CBCL; Achenbach & Rescorla, 2000), have undergone downward extensions so that the preschool versions are available for children as young as 18 months. Limited research, however, has been conducted on the preschool versions of the BASC‐2 and CBCL. This study examined the consistency of results from the two preschool versions when completed by parents of clinically referred preschoolers. Comparisons of similarly named scales found significant correlations. Mean scores for several of the constructs were significantly different, however, and often resulted in inconsistent classification decisions. © 2010 Wiley Periodicals, Inc.  相似文献

Schooling and the knowledge acquired at school have been considered both a cause of loss of indigenous knowledge (because it opens pathways to the non-indigenous world and worldviews) and a potential remedy to its demise (if educational curricula is aligned with indigenous realities by giving instruction in local languages and incorporating local knowledge in school content). We test the association between academic and local environmental knowledge using data from a society of forager-horticulturalists in the Bolivian Amazon who were exposed to a partially contextualized school curriculum. We found that although schooling and academic knowledge bear a negative association with local knowledge the magnitude is low, probably because schooling was partially contextualized. Contextualized learning might help avoid that the provision of universal education comes at the cost of humanity's cultural diversity.  相似文献

At a time when government funding cuts mean that public libraries face an uncertain future and need to make sure they stay relevant to young users and their families, this paper explores what counts as literacy for young children in a public library in a town in the East Midlands, UK. It is based on a study which adopted an ethnographic approach, drawing on Lefebvre's spatial theory to understand how a library space presents literacy to young children and their carers, and how this then shapes the literacy practices and events that happen in this space. The study shows that dominant discourses are bound up in what the library staff understand to be their role in promoting and supporting young children's literacy, and that, often, they organise the space and literacy events in ways that reflect these discourses. However this paper argues that it is not only the library staff that create space in the library, as carers and their children are sometimes seen to create alternative spaces which challenge and subvert the way the librarians would like the space to be used and understood.  相似文献

This research presents a review of the literature around meeting students’ learning needs in Australian schools. It is referenced to one group of students with refugee experience who have been in Australian schools for over 15 years; students with a background of oracy from Southern Sudan. The development of psychological health and literacy competencies are two of the most critical and complex responsibilities undertaken by education, and, in the case of these students two of the most significant when considered in relation to successful settlement, acculturation and assimilation. In presenting this literature, the bigger picture of how schools can fail, not only these students, but for any number of students from diverse backgrounds, becomes startlingly obvious, as do the ways in which the current political agenda inherent in the public education system in Australia privileges students of specific class and culture. Finally, recommendations are made regarding the development of policy and the concentration on pedagogical practices which acknowledge and respect the strengths and capabilities of this group of students.  相似文献

Abstract

Few researchers have used social cognitive theory and environment-based constructs to predict physical activity (PA) and fitness in underserved middle-school children. Hence, we evaluated social cognitive variables and perceptions of the school environment to predict PA and fitness in middle school children (N = 506, ages 10-14 years). Using multiple regression analyses we accounted for 12% of the variance in PA and 13-21% of the variance in fitness. The best predictors of PA were barrier self-efficacy, classmate social support, and gender; whereas, only gender predicted fitness. The results affirmed the importance of barrier self-efficacy and gender differences. Our findings regarding classmate social support are some of the first to illuminate the importance of school-specific peers in promoting PA.  相似文献

Abstract

The aims of this study were two-fold: (1) to consider the criterion-related validity of the multi-stage fitness test (MSFT) by comparing the predicted maximal oxygen uptake ([Vdot]O2max) and distance travelled with peak oxygen uptake ([Vdot]O2peak) measured using a wheelchair ergometer (n = 24); and (2) to assess the reliability of the MSFT in a sub-sample of wheelchair athletes (n = 10) measured on two occasions. Twenty-four trained male wheelchair basketball players (mean age 29 years, s = 6) took part in the study. All participants performed a continuous incremental wheelchair ergometer test to volitional exhaustion to determine [Vdot]O2peak, and the MSFT on an indoor wooden basketball court. Mean ergometer [Vdot]O2peak was 2.66 litres · min?1 (s = 0.49) and peak heart rate was 188 beats · min?1 (s = 10). The group mean MSFT distance travelled was 2056 m (s = 272) and mean peak heart rate was 186 beats · min?1 (s = 11). Low to moderate correlations (ρ = 0.39 to 0.58; 95% confidence interval [CI]: ?0.02 to 0.69 and 0.23 to 0.80) were found between distance travelled in the MSFT and different expressions of wheelchair ergometer [Vdot]O2peak. There was a mean bias of ?1.9 beats · min?1 (95% CI: ?5.9 to 2.0) and standard error of measurement of 6.6 beats · min?1 (95% CI: 5.4 to 8.8) between the ergometer and MSFT peak heart rates. A similar comparison of ergometer and predicted MSFT [Vdot]O2peak values revealed a large mean systematic bias of 15.3 ml · kg?1 · min?1 (95% CI: 13.2 to 17.4) and standard error of measurement of 3.5 ml · kg?1 · min?1 (95% CI: 2.8 to 4.6). Small standard errors of measurement for MSFT distance travelled (86 m; 95% CI: 59 to 157) and MSFT peak heart rate (2.4 beats · min?1; 95% CI: 1.7 to 4.5) suggest that these variables can be measured reliably. The results suggest that the multi-stage fitness test provides reliable data with this population, but does not fully reflect the aerobic capacity of wheelchair athletes directly.  相似文献

Abstract

The purpose of the study was to determine which laboratory-based modality provides the most valid physiological and biomechanical representation of over-ground sports wheelchair propulsion. Fifteen able-bodied participants with previous experience of wheelchair propulsion performed a 3-minute exercise trial at three speeds (4, 6 and 8 km ? h–1) in three testing modalities over separate sessions: (i) over-ground propulsion on a wooden sprung surface; (ii) wheelchair ergometer propulsion; (iii) treadmill propulsion at four different gradients (0%, 0.7%, 1.0% and 1,3%). A 0.7% treadmill gradient was shown to best reflect the oxygen uptake (7.3 to 9.1% coefficient of variation (CV)) and heart rate responses (4.9 to 6.4% CV) of over-ground propulsion at 4 and 6 km ? h–1. A 1.0% treadmill gradient provided a more valid representation of oxygen uptake during over-ground propulsion at 8 km ? h–1 (8.6% CV). Physiological demand was significantly underestimated in the 0% gradient and overestimated in the 1.3% gradient and wheelchair ergometer trials compared to over-ground trials (P<0.05). No laboratory-based modality provided a valid representation of the forces applied during OG (≥ 18.4% CV). To conclude, a 0.7% treadmill gradient is recommended to replicate over-ground wheelchair propulsion at lower speeds (4 and 6 km ? h–1) whereas a 1.0% gradient may be more suitable at 8 km ? h–1.  相似文献
