225 children (ages 4 to 8, 103 girls, 37.5% Mexican-American) participated, reporting who provides support, frequency of receiving different types of support, and satisfaction with support received. These reports were subjected to factor analyses and results did not fit a prior conceptualization. Exploratory factor analyses resulted in a three factor solution that was both more interpretable and the solutions were more similar for reports of frequency of receiving support and satisfaction. A total of six subscale scores were computed, three each for the frequency and the satisfaction items, which were subsequently labelled: informational/emotional, recreational, and practical support. Analyses of the empirically derived subscale scores suggested that young, pre- and early elementary school-aged children responded to questions about their social support in reasonably reliable and valid ways. Significant correlations with indices of perceived competence and acceptance resulted. Remarkably little is known about young children's perceptions of their social worlds, or specifically the nature of support they think is available or that they actually receive. These data suggest that gathering this information from the children themselves is feasible. Ultimately such information should be critical for the design and evaluation of early childhood curricula instructing children about social relations generally, and specifically, who they can turn to for support. 相似文献

Current policy in relation to special needs prioritises early intervention and inclusive education, at least as 'good intentions' This article argues for a paradigmatic shift away from individualist models of learning and disability. The social context of play is emphasised as the crucial arena for realising such good intentions, as long as it is geared to responding to, and developing, the self-determination, control, and identity of young disabled children becoming disabled adults in a disabling society. 相似文献

Adults experience greater self-other bodily overlap in romantic than platonic relationships. One of the closest relationships is between mother and infant, yet little is known about their mutual bodily representations. This study measured infants’ sensitivity to bodily overlap with their mother. Twenty-one 6- to 8-month-olds watched their mother’s face or a stranger’s face being stroked synchronously versus asynchronously with their own face. Infants preferred synchrony only when viewing their mother, not when viewing the stranger. Infants who strongly preferred synchrony with their mother also experienced less coordination with her in naturalistic interactions. Infants thus appear sensitive to bodily overlap with their mother, and this overlap reflects dyadic coordination, supporting theoretical accounts of intersubjectivity in the development of the bodily self. 相似文献

This study investigated the effect of including explicit nature of science (NOS) content in read-alouds of elementary science trade books on the teaching and learning of NOS. We focused on three aspects of NOS: the creative, the empirical, and the inferential NOS. The trade books were read aloud by teachers in three hierarchical levels: Level I served as a control and consisted of a trade book that remained unmodified, Level II consisted of a trade book that had been modified to include explicit references to NOS, and Level III consisted of a modified trade book accompanied by educative curriculum materials that were aimed at improving the teachers' views of NOS as well as supporting teaching about NOS. We used the Views of Nature of Science Questionnaire-form CE (VNOS-CE) preintervention and postintervention to determine changes in teachers' views of NOS and interviews preintervention and postintervention to determine changes in students' views. Audio recordings of read-alouds were used to determine changes in teaching practice, including the frequency and the quality (i.e., naïve or informed) of the NOS references in the discussions. Interviews were used to determine teachers' perceptions of the modified trade books and educative curriculum materials. We found that both teachers and students developed more informed views of the targeted NOS aspects after the intervention and that teachers addressed NOS more often, and in a more informed manner, when they had trade books that explicitly supported NOS instruction and educative curriculum materials that supported their learning about NOS. Furthermore, they perceived the intervention materials favorably. Teachers' views and practices were able to change in tandem because of the intervention materials that supported explicit NOS instruction. We highlight the need for more widespread development of similar educative curriculum materials. 相似文献

This study examines the process of change among grade 4 teachers (students aged 9–10 years) who participated in a yearlong
Teacher Quality Grant innovation program. The concerns-based adoption model (CBAM), which informed the design and implementation
of the program, was used to examine the process of change. Two questions guided the investigation: (1) How did teachers’ concerns
about and levels of use of the innovation evolve during the course of the project? (2) What changes in teachers’ perceptions
and practices arose as a result of the innovation? Results showed that several of the teachers’ concerns evolved from self/task
toward impact. With continued support, several participants achieved routine levels of use, which they sustained beyond the
project. 相似文献

In 2009, the North Carolina Community College System (NCCCS) began the process of redesigning developmental mathematics (DMA) courses. The first classes were offered in 2012 with final state implementation in fall 2013. The purpose of this study was to examine the subsequent gateway course success rates achieved by former DMA students in relation to the delivery method (i.e., teacher-centered, student-centered, and computer-centered) used in the redesigned North Carolina DMA courses. Students included in this study took a gateway math course and a developmental math course during the same or previous academic year. Students who participated in student-centered and computer-centered instruction in their DMA course had a statistically significant pass rate in subsequent gateway courses compared with students receiving teacher-centered instruction. Along with the findings, this paper discusses considerations for redesign, including the choice of delivery methods and instructional techniques, and recommendations for further research. 相似文献

Twenty highly trained, eumenorrhoeic female endurance runners were studied over three consecutive menstrual cycles. Average training distance per week, total years training and mood states were recorded throughout the three cycles. Salivary progesterone and menstrual cycle diaries were recorded over the first two cycles to identify luteal phase onset and the presence of any menstrual irregularities. Saliva samples were collected daily over the third cycle for analysis of immunoglobulin A (IgA) concentration and secretion and saliva flow rate. Twoway analysis of variance (ANOVA) revealed no significant differences in mood states across the phases of the menstrual cycle ( P > 0.05). Training logs indicated that training did not alter throughout the 3 month study. One-way ANOVArevealed no significant differences in IgA concentration ( P = 0.92), secretion rate ( P = 0.84) or saliva flow rate ( P = 0.95) across the phases of the menstrual cycle. Pearson's product-moment correlation revealed no relationship between IgA concentration and progesterone between the phases of the cycle ( r = 0.39). We conclude that, in ovulatory female endurance runners whose physical and emotional stress are stable, IgA concentration is not significantly affected by fluctuations in progesterone during the menstrual cycle. 相似文献

Limited information exists about the movement patterns of field-hockey players, especially during elite competition. Time–motion analysis was used to document the movement patterns during an international field-hockey game. In addition, the movement patterns of repeated-sprint activity were investigated, as repeated-sprint ability is considered to be an important fitness component of team-sport performance. Fourteen members of the Australian men's field-hockey team (age 26±3 years, body mass 76.7±5.6?kg, [Vdot]O2max 57.9±3.6?ml?·?kg?1?·?min?1; mean±s) were filmed during an international game and their movement patterns were analysed. The majority of the total player game time was spent in the low-intensity motions of walking, jogging and standing (46.5±8.1, 40.5±7.0 and 7.4±0.9%, respectively). In comparison, the proportions of time spent in striding and sprinting were 4.1±1.1 and 1.5±0.6%, respectively. Our criteria for ‘repeated-sprint’ activity (defined as a minimum of three sprints, with mean recovery duration between sprints of less than 21?s) was met on 17 occasions during the game (total for all players), with a mean 4±1 sprints per bout. On average, 95% of the recovery during the repeated-sprint bouts was of an active nature. In summary, the results suggest that the motion activities of an elite field-hockey competition are similar to those of elite soccer, rugby and Australian Rules football. In addition, the investigation of repeated-sprint activity during competition has provided additional information about the unique physiological demands of elite field-hockey performance. 相似文献
