The inconsistencies of regulation and inspection in UK early childhood services are examined. The rationale and regulatory requirements for daycare put forward by the Department of Health are compared with those currently operating within the Department for Education and Employment for schools and nursery education. The policy frameworks within the two departments are based on different assumptions about practice and lead to major inconsistencies of delivery. A more coherent policy is needed to resolve these inconsistencies.  相似文献

This study examines the effects of a scale-reduced play environment on temporal aspects of play behavior. Specifically, it examines the amount of time required to enter complex forms of play, the length of play segments, and the percentage of total play time spent in complex play under normal environmental conditions (full-size, control) and under scale-reduced environmental conditions (experimental). Eleven subjects (mean age of 4 years 2 months) were observed during unstructured play activity with playdough in a small-n, A-B-A-B design. Subjects served as their own controls and were self-motivated relative to the activity. The play structure (scale-reduced environment) consisted of a screened wooden frame 7' (L) x 5' (W) x 5' (H) over a vinyl floor. Results indicate subjects enter complex forms of play more quickly, engage in play segments of longer duration and tend to spend a slightly greater percentage of their overall play time in complex play under experimental conditions, as hypothesized. This study suggests attention span and information processing may be affected by the scale of the play environment. : -.  相似文献

Abstract

This study aimed to produce age- and sex-specific physical fitness reference data for Portuguese youth; to report the prevalence of youth in the healthy zone of physical fitness according to the FITNESSGRAM® criteria; to verify the agreement between the Portuguese physical fitness percentiles and the FITNESSGRAM® healthy zones. In 2008, 22,048 Portuguese children and adolescents (10–18 years) were evaluated. Physical fitness (curl-ups, push-ups, 20-m shuttle run and modified-back-saver-sit-and-reach tests) was evaluated using the FITNESSGRAM® Test Battery 8.0. Smoothed percentile curves were estimated using Cole’s LMS method. Boys consistently outperformed girls in every physical fitness test, except for the modified-back-saver-sit-and-reach tests. In both sexes and for all physical fitness tests, higher percentile values were observed at older ages. The 50th percentile of all physical fitness tests had the highest accuracy to discriminate between under healthy zone and healthy zone of the FITNESSGRAM®. Portuguese schools and physical education teachers may considerer the 50th percentile for age and sex or the FITNESSGRAM® criteria for classifying participants in the healthy zone as acceptable cut-offs, above which youth should be considered fit. These reference values can be used as normative data and for baseline values for subsequent surveillance of the physical fitness of Portuguese youth.  相似文献

Abstract

The aims of the this prospective study were to analyse physical activity (PA) engagement during the first and second trimesters, considering the different guidelines published on PA, to document the individual characteristics associated with the accomplishment of these guidelines and to examine pregnant women’s perceived barriers to leisure PA, using a socioecological framework. A sample of 133 pregnant women in two stages – at 10–12 weeks’ gestation (T1) and 20–22 weeks’ gestation (T2) – were evaluated. PA was assessed by accelerometry during the T1 and T2 evaluation stages. Socio-demographic characteristics, lifestyle factors and barriers to leisure PA were assessed via questionnaire. A large proportion of women (ranging from 32% to 96%) did not reach the levels of PA recommended by the guidelines. There were no significant differences between T1 and T2 with regard to compliance with PA recommendations. A decrease in PA levels from T1 to T2 was noted for all recommendations. No associations were found between participants’ characteristics and adherence to the recommendations in T1 and T2. No significant differences were found in barriers to leisure PA between T1 and T2. The most commonly reported barriers to leisure PA were intrapersonal, not health related. Our results indicate that there were no differences between trimesters regarding compliance of PA recommendations, and perceived barriers were similar in both trimesters.  相似文献

This yearlong study was implemented in seventh-grade life science classes with the students' regular teacher serving as teacher/researcher. In the study, a method of scoring concept maps was developed to assess knowledge and comprehension levels of science achievement. By linking scoring of concept maps to instructional objectives, scores were based upon the correctness of propositions. High correlations between the concept map scores and unit multiple choice tests provided strong evidence of the content validity of the map scores. Similarly, correlations between map scores and state criterion-referenced and national norm-referenced standardized tests were indicators of high concurrent validity. The approach to concept map scoring in the study represents a distinct departure from traditional methods that focus on characteristics such as hierarchy and branching. A large body of research has demonstrated the utility of such methods in the assessment of higher-level learning outcomes. The results of the study suggest that a concept map might be used in assessing declarative and procedural knowledge, both of which have a place in the science classroom. One important implication of these results is that science curriculum and its corresponding assessment need not be dichotomized into knowledge/comprehension versus higher-order outcomes. © 1998 John Wiley & Sons, Inc.

Teacher coaching is essential to support self-directed learning, but requires a lot of time and energy. This mixed-methods study investigated the effects of using an e-portfolio with a self-coaching protocol and limited teacher coaching on the development of self-directed learning skills and motivation. With regard to self-directed learning, students’ overestimation of performance on learning tasks grew over time, while their ability to formulate points for improvement did not change significantly. With regard to motivation, students’ controlled (i.e. largely extrinsic) motivation increased while their autonomous (i.e. largely intrinsic) motivation decreased. Thematic analysis of interviews demonstrated students needed more support and feedback from their teacher. The use of suboptimal cues for performance assessment and an imperfect balance between autonomy and support hampered self-directed learning and motivation. We recommend providing just-in-time feedback about performance on learning tasks and giving students some autonomy over the choice of learning tasks, to enhance reflection and motivation.  相似文献

Although positive teacher‐student relationships are known to aid students’ academic self‐regulation, the emotional aspects of teacher liking are often neglected within research. The present study used a large sample of seventh‐ and eighth‐grade students (N = 1,088; MAge =  13.7) in secondary schools in Germany to investigate whether the motivation students gain from specific well‐liked teachers (i.e., that students identify) can moderate the relation between their perception of teacher‐student relationships overall and academic self‐regulation (intrinsic motivation, identified, introjected, and external regulation). By means of latent moderated structural equations, students’ motivation based on liking one specific teacher was found to moderate the association between teacher‐student relationships and intrinsic motivation. The present study makes a contribution to the existing research on teacher‐student relationships and academic self‐regulation by investigating the role of students’ motivation related to the liking of a specific teacher. Results indicate that when early adolescent students can identify a well‐liked teacher, they tend to have higher levels of academic motivation. Hence, students’ motivation based on liking a single teacher compensates for generally low‐quality teacher‐student relationships and their respective impact on students’ intrinsic motivation.  相似文献

Analysis of interviews obtained from a random sample of 930 adult women in San Francisco revealed that 17% or one out of approximately every six women who had a stepfather as a principal figure in her childhood years, was sexually abused by him. The comparable figures for biological fathers were 2% or one out of approximately 40 women. In addition, when a distinction was made between Very Serious Sexual Abuse (including experiences ranging from forced penile-vaginal penetration to non-forceful attempted fellatio, cunnilingus, and anal intercourse) and other less serious forms, 47% of the cases of sexual abuse by stepfathers were at the Very Serious level of violation compared with 26% by biological fathers. Possible explanations for these startling discrepancies are discussed, and some of the implications for remarriage are considered.  相似文献

The purposes of the study were to analyse the promotion of scientific literacy through practical research activities and to identify children's conceptions about scientists and how they do science. Elementary school children were engaged in two scientific experiments in a marine biology research laboratory. A total of 136 students answered a questionnaire about their previous habits towards science and carried out the following actions: (1) a guided visit to the laboratory, (2) a brief presentation of the research theme, (3) the development of two experiments, and (4) a questionnaire about the experiments and science conceptions. The research methods included observation, document analysis, and content analysis of the answers to the questionnaires. Additionally, each visit was video recorded in order to design learning materials. The results revealed that most of the pupils were able to follow every stage of experimentation. However, some of them misinterpreted results and conclusions. One implication of the study is that this type of outdoor activity is extremely important to promote meaningful science learning in children, but more care should be taken in practical science activities so that children can overcome some common difficulties when performing scientific inquiry.  相似文献
