Identifying high-quality centre-based childcare using quantitative data-sets: what the numbers do and don't tell us

Quantitative approaches to defining and measuring quality in early childhood education and care (ECEC) have provided a key platform for policy development. Yet their strengths and limitations as informants of high-quality ECEC have not been tested. In this study we examine two sources of quantitative data collected over a five-year period for 74 long day care centres: (1) the Early Childhood Environment Rating Scale-Revised and Infant-Toddler Environment Rating Scale instruments which are well-established observational measures; and (2) Australia's nationally administered Quality Improvement and Accreditation System which involves a self-study and validation process. Correspondence over time and across measures was more consistent for the centres identified as providing lower quality ECEC. Variability in ratings of quality was more evident in lower quality centres, whereas high-quality centres showed less variability over time. High quality, however, was less consistently identified across measures. Discussion focuses on the strengths and limitations of these measures of quality, and the implications these have for policy development and future research.     

Energy expenditure and dietary intake in professional football players in the Dutch Premier League: Implications for nutritional counselling

ABSTRACT

Selecting effective dietary strategies for professional football players requires comprehensive information on their energy expenditure (EE) and dietary intake. This observational study aimed to assess EE and dietary intake over a 14-day period in a representative group (n = 41) of professional football players playing in the Dutch Premier League (Eredivisie). Daily EE, as assessed by doubly labelled water, was 13.8 ± 1.5 MJ/day, representing a physical activity level (PAL) of 1.75 ± 0.13. Weighted mean energy intake (EI), as assessed by three face-to-face 24-h recalls, was 11.1 ± 2.9 MJ/day, indicating 18 ± 15% underreporting of EI. Daily EI was higher on match days (13.1 ± 4.1 MJ) compared with training (11.1 ± 3.4 MJ; P < 0.01) and rest days (10.5 ± 3.1 MJ; P < 0.001). Daily carbohydrate intake was significantly higher during match days (5.1 ± 1.7 g/kg body mass (BM)) compared with training (3.9 ± 1.5 g/kg BM; P < 0.001) and rest days (3.7 ± 1.4 g/kg BM; P < 0.001). Weighted mean protein intake was 1.7 ± 0.5 g/kg BM. Daytime distribution of protein intake was skewed, with lowest intakes at breakfast and highest at dinner. In conclusion, daily EE and PAL of professional football players are modest. Daily carbohydrate intake should be increased to maximize performance and recovery. Daily protein intake seems more than adequate, but could be distributed more evenly throughout the day.     

Looking at the Social Aspects of Nature of Science in Science Education Through a New Lens

Particular social aspects of the nature of science (NOS), such as economics of, and entrepreneurship in science, are understudied in science education research. It is not surprising then that the practical applications, such as lesson resources and teaching materials, are scarce. The key aims of this article are to (a) synthesize perspectives from the literature on economics of science (EOS), entrepreneurship, NOS, and science education in order to have a better understanding of how science works in society and (b) illustrate how such a synthesis can be incorporated in the practice of science education. The main objectives of this article are to (1) argue for the role and inclusion of EOS and entrepreneurship in NOS and re-define entrepreneurship in the NOS context; (2) explore the issues emerging in the “financial systems” of the Family Resemblance Approach (FRA) to NOS and propose the inclusion of contemporary aspects of science, such as EOS and entrepreneurship, into NOS; (3) conceptualize NOS, EOS, and entrepreneurship in a conceptual framework to explain how science works in the society; and (4) transform the theoretical knowledge of how science operates in society into practical applications for science teaching and learning. The conceptual framework that we propose illustrates the links between State, Academia, Market and Industry (the SAMI cycle framework). We suggest practical lesson activities to clarify how the theoretical discussions on the SAMI cycle framework can be useful and relevant for classroom practice. In this article, science refers to physics, chemistry, and biology. However, we also recommend an application of this framework to other sciences to reveal their social-institutional side.     

Facilitating invented spelling through language analysis instruction: An integrated model

Invented spelling ability reflects young children's developing awareness of the internal structure of words-at syllabic, phonemic, and morphemic levels, as well as their lettersound knowledge. Controlled intervention studies have demonstrated that these language analysis skills can be taught in kindergarten, with a significant effect on early spelling. This paper examines the effects of an instructional approach that emphasized integration of language analysis teaching into the whole-language kindergarten curriculum. Children who received this type of instruction were, on average, representing all of the phonemes in written words at the end of kindergarten, and their performance continued to improve into first grade.     

Emotion Regulation, Parenting and Display of Social Reticence in Preschoolers

The study of social reticence in early childhood has focused primarily on those dispositional, intra-individual factors that might account for its demonstration among peers. Little is known, however, about the relations between social reticence and its association with the quality of parenting behaviors. Indeed, the independent and interactive “contributions” of dispositional and parenting factors to children's demonstration of socially reticent behavior have not received adequate attention. In this study, 188 preschool children and their mothers were observed during unstructured Free-play and a structured Lego-building teaching task. Additionally, the children were observed in quartets of same-sex, same-age unfamiliar peers. Results indicated that children's shy, socially reticent behavior was predicted by the extent to which mothers were over-solicitous during Free-play. In addition, preschooler's expressions of reticent behavior were predicted by the interactions between emotion dysregulation and the lack of maternal guidance and control during a teaching task. Emotionally dysregulated children whose mothers provided little control in this putatively stressful teaching task were more likely to be shy and reticent. This relation was non-significant for dysregulated children with mothers who provided high levels of guidance. The results suggest that early childhood educators offer reticent/shy children opportunities to explore their impersonal and social milieus and to warmly encourage such exploratory activities. Without such encouragement and opportunity building, reticent preschoolers may suffer from not having experienced sufficient exploration-to-play sequences thereby stifling the problem-solving competencies derived from such experiences.
