Research Findings: Integrated services for young children and families are part of the new policy landscape in early childhood, but there is limited evidence of the effectiveness of these programs and how they develop on the ground. This study examined the use of the Early Development Instrument (EDI) as both a summative program evaluation tool and as a formative program improvement tool supporting practitioners in Toronto First Duty, an integrated services demonstration project that combined kindergarten, child care, and parenting supports in public schools. Pre-post comparisons at community demonstration sites and comparisons with matched community sites using the EDI suggested that the demonstration program was associated with modest improvements in emotional and social domains of children's development. Mixed methods and multiple measures were used to contextualize summative findings in case studies across demonstration sites. The case studies explored how integration was implemented at different sites and how dimensions of enacted integration might contribute to positive outcomes for children and families. A case study of one site showed how an integrated staff team used EDI school-level profiles, along with formative feedback on program quality, to target and improve programming. Over the course of implementation, the integrated program environment quality ratings and EDI scores improved in relevant areas assessing quality of interaction and social–emotional development. Practice or Policy: Findings are discussed in terms of the role of the EDI in program evaluation and in improvement of practice. The potential value of integrated early childhood services and the challenges of evaluating complex community initiatives are also discussed.  相似文献

The synchrotron characterisation of archaeological and heritage materials has undergone a steep development in the past years, among a range of other advanced characterisation techniques. For synchrotron techniques alone, close to a hundred articles were published in 2011 on such materials, prompting new developments at large scale facilities. However, few publications have discussed the speci?c characteristics of heritage materials in their advanced spectroscopic and imaging study. Here, we suggest that a greater consideration be put on the speci?cities of ancient materials and their theoretical implications on the analytical process. In particular, we discuss the importance of the a posteriori framework of the study of heterogeneous materials considered in their historicity as structuring parameters of their study. Major implications are the relevance of trace analyses, those of majors and we suggest, more importantly, the dynamics between both endpoints. The on-going development of multimodal spectral imaging appears as a way to better address corresponding difficulties. Epistemologically, we suggest that a re?exive approach be developed to explain, structure and possibly contribute to narrowing down the ?eld of possible methodological research.  相似文献

In this paper, we describe an experiment that compared the use of a Tangible User Interface (physical objects augmented with digital information) and a set of Contrasting Cases as a preparation for future learning. We carried out an experiment (N?=?40) with a 2?×?2 design: the first factor compared traditional instruction (“Tell & Practice”) with a constructivist activity designed using the Preparation for Future Learning framework (PFL). The second factor contrasted state-of-the-art PFL learning activity (i.e., students studying Contrasting Cases) with an interactive tabletop featuring digitally enhanced manipulatives. In agreement with prior work, we found that dyads of students who followed the PFL activity achieved significantly higher learning gains compared to their peers who followed a traditional “Tell & Practice” instruction (large effect size). A similar effect was found in favor of the interactive tabletop compared to the Contrasting Cases (small-to-moderate effect size). We discuss implications for designing socio-constructivist activities using new computer interfaces.  相似文献

Abstract

This article looks at the French state’s approach to the “colonies de vacances” between 1944 and 1958. Created in 1876 by the Reverend Bion in Zurich, these summer camps originated as a charitable institution: their initial purpose was to provide rural retreats and to restore the health of poor urban youth. Set up on French soil in 1880, these institutions gradually grew in France in the late nineteenth and early twentieth centuries. Considered both as complements to the republican school and as extensions of the “patronages” (parish unions), they were important for children and adolescents from the industrial city suburbs, and were enshrined in the leisure policies of the Popular Front from 1936 onwards. After the Second World War, summer camps in France became a major social institution (300,000 children went to summer camps in 1945, 900,000 in 1949) in response to both hygiene and educational needs. Based on the archives of the Directorate of Youth Movements and Popular Education (1944–1947) and the General Directorate of Youth and Sports (1948–1958), this article aims to examine the politics behind the organisation of these summer camps and to demonstrate the social and political importance of these popular educational institutions which, in 1957, involved 1.35 million French children and teenagers. Although the history of French summer camp federations (UFCV, CEMEA, CPVC, UFOVAL, etc.) has been widely studied, how the state sees its role and influences these organisations has mostly been considered indirectly. The intention is to show that among the educational, cultural and sports policies implemented during the Fourth Republic in France, those related to the organisation of “colonies de vacances”, and therefore the organisation of holidays for a very large number of children and teenagers, occupy a significant place. In 1944, the summer camps were widely supported by the French state, which also planned to regulate this booming sector. The creation of qualifications for summer camp staff and directors in 1949 obliged organisations to start training schemes: they trained staff and directors to work in the municipal camps, associations, etc. Security issues led to the state tightening control of the summer camps, their recruitment and their activities. There was a great deal of political investment in these “colonies de vacances” during this period, and this was reflected in the creation of a Ministerial Education Committee in 1950, a general and regional body of inspectors for these camps, etc. However, the considerable expansion of summer camps posed increasing problems at the national political level resulting in changes to the initial subsidy policies. The State played a major part in crucial issues such as the sociological diversification of these institutions and the changes in their social role according to evolving sociocultural trend. The fact remains that the “colonies de vacances” were for the French state a centrepiece of the “popular education” that the political actors of the Fourth Republic wanted to implement in order to build the France of the post-war period..  相似文献

This study examines gender-based attributional ambiguity among higher education administrators in the US, specifically academic deans. Attributional ambiguity involves situations in which members of underrepresented groups cannot determine whether interactions both negative and positive have occurred because of their minority status or for some unrelated yet plausible reason. A conceptual model of attributional ambiguity in higher education administration is presented highlighting the types of situations that produce this ambiguity, two variants of attributional ambiguity (i.e. cognitive and social), and the psychological and organizational consequences of such ambiguity. Reasons that attributional ambiguity is inherent to higher education administration are examined including the fluidity of gender roles, the culture of academia, and leaders’ minimization of discriminatory experiences. Implications for professional practice are also presented such as the need for curricula, trainings, mentoring, and coaching that addresses attributional ambiguity and greater publicity related to women’s underrepresentation in leadership roles in higher education.  相似文献

The primary aim of this study was to determine whether facial feature tracking reliably measures changes in facial movement across varying exercise intensities. Fifteen cyclists completed three, incremental intensity, cycling trials to exhaustion while their faces were recorded with video cameras. Facial feature tracking was found to be a moderately reliable measure of facial movement during incremental intensity cycling (intra-class correlation coefficient = 0.65–0.68). Facial movement (whole face (WF), upper face (UF), lower face (LF) and head movement (HM)) increased with exercise intensity, from lactate threshold one (LT1) until attainment of maximal aerobic power (MAP) (WF 3464 ± 3364mm, < 0.005; UF 1961 ± 1779mm, = 0.002; LF 1608 ± 1404mm, = 0.002; HM 849 ± 642mm, < 0.001). UF movement was greater than LF movement at all exercise intensities (UF minus LF at: LT1, 1048 ± 383mm; LT2, 1208 ± 611mm; MAP, 1401 ± 712mm; P < 0.001). Significant medium to large non-linear relationships were found between facial movement and power output (r2 = 0.24–0.31), HR (r2 = 0.26–0.33), [La?] (r2 = 0.33–0.44) and RPE (r2 = 0.38–0.45). The findings demonstrate the potential utility of facial feature tracking as a non-invasive, psychophysiological measure to potentially assess exercise intensity.  相似文献

In this paper, the characteristics of fluid mixing time in a novel extra-loop fluidized bed were studied. The results showed that the mixing time was shortened with the increase of fluid velocity. All the discrete numbers of the reactor were above 0.2. The serial number n was 2.5 -3.0. It was judged accordingly that the reactor fluid state was continous stirred tank reactor (CSTR) mainly. When the inspiratory capacity increased the mixing time of the reactor was shortened. Thus the air input was beneficial for the fluid mixing. During the three phases mixing process, the mixing time of the reactor could be decreased by the n increase of carrier and air loading together, but the change was not significant. The parameters affecting the reactor fluid state were fluid velocity, inspiratory capacity and carrier. KLa could be increased with the air loading increase, and at the same gas/liquid ratio when the pressure drop was high, KL~ value was increased. The amount of carrier complex influence on KLa. As the carrier loading continued to increase, its value had been dropped but the changes was not significant, and optimization condition was found at above 800 1 000 g carrier loading (pouzzolane) or 600 g PVC. Under gas/liquid ratio of 0.8% -5.2%, KLa was (0.62-1.37)×10^-2· s^-1.  相似文献

Abstract

A large body of research in support of the reciprocal effects model of causal ordering demonstrates that prior academic self-concept predicts subsequent academic achievement beyond what can be explained in terms of prior achievement. Here we evaluate the generalizability of this support for the reciprocal effects model to a physical activity context in which achievement is reflected in gymnastics skills on a standardized gymnastics performance test evaluated by expert judges. Based on the responses of 376 adolescents collected at the start (T1) and end (T2) of a gymnastics training programme, there is support for a reciprocal effects model in which there are significant paths leading from both T1 gymnastics self-concept to T2 gymnastics skills and from T1 gymnastics skills to T2 self-concept. Although there were gender and age effects (girls and older participants had better gymnastics skills, boys had higher self-concepts), multiple group structural equation models indicated that support for the reciprocal effects model generalized over responses by boys and girls. In summary, self-concept and performance are both determinants and consequences of each other.  相似文献

Abstract

The aim of the current study was to investigate the validity and reliability of a radio frequency-based system for accurately tracking athlete movement within wheelchair court sports. Four wheelchair-specific tests were devised to assess the system during (i) static measurements; (ii) incremental fixed speeds; (iii) peak speeds; and (iv) multidirectional movements. During each test, three sampling frequencies (4, 8 and 16 Hz) were compared to a criterion method for distance, mean and peak speeds. Absolute static error remained between 0.19 and 0.32 m across the session. Distance values (test (ii)) showed greatest relative error in 4 Hz tags (1.3%), with significantly lower errors seen in higher frequency tags (<1.0%). Relative peak speed errors of <2.0% (test (iii)) were revealed across all sampling frequencies in relation to the criterion (4.00 ± 0.09 m · sˉ1). Results showed 8 and 16 Hz sampling frequencies displayed the closest-to-criterion values, whilst intra-tag reliability never exceeded 2.0% coefficient of variation (% CV) during peak speed detection. Minimal relative distance errors (<0.2%) were also seen across sampling frequencies (test (iv)). To conclude, the indoor tracking system is deemed an acceptable tool for tracking wheelchair court match play using a tag frequency of 8 or 16 Hz.  相似文献
