Research Findings: The present cross-sectional study investigated the question of whether 6 different temperament dimensions (inhibition to novelty, social orientation, motor activity, positive emotionality, negative emotionality, and attention) influenced cognitive and affective theory of mind (ToM) in 168 children (86 three/four-year-olds and 82 four/five-year-olds). Temperament was measured via a parent-report questionnaire, cognitive ToM via a classical false-belief task, and affective ToM via a comprehensive test tapping 3 levels of emotion comprehension (external, mental, and reflexive). In addition, language competence was assessed with a direct test evaluating both receptive and expressive language. The results showed that after we controlled for language ability, inhibition to novelty predicted higher levels of cognitive ToM in 4/5-year-old children. In addition, higher levels of social orientation predicted better comprehension of the external aspects of emotion in both younger and older children. Practice or Policy: Our results highlight the importance of the early identification of less sociable children, who might benefit from training interventions aimed at increasing their affective ToM abilities. At the same time, they are also consistent with previous evidence indicating that an inhibited approach to social interaction can promote false-belief understanding.  相似文献

Policies aiming to improve educational outcomes are typically based on academic testing data. However, such data only reflect the performance of students who completed the tests. It is possible that students who were absent have shared characteristics. The proportion of students absent out of all eligible school students and whether they have shared characteristics has not been investigated, as this is only possible through the use of linked administrative data. Participants were born in Western Australia in 1994 and 1995, and their birth records were linked to participation status in the Year 9 academic tests to determine the proportion of students who were absent. Logistic regression was conducted to investigate characteristics which predicted absence on test day. A proportion of non-Aboriginal (3.2 %) and Aboriginal students (21.9 %) were absent on test day. Risk factors which predicted the absence included contact with Child Protection and Family Services, history of maternal mental health problems, and fathers aged below 20 years at the time of their child’s birth. A significant proportion of students was absent and therefore not represented in academic achievement information. These students were more likely to have experienced adverse events and therefore are not randomly absent. As these data are typically used to inform policies which aim to improve educational outcomes, they may lack the necessary information to adequately address the complex needs of students who are absent on test day. However, findings suggest that service providers, as well as schools may play an important role in encouraging participation in school.  相似文献

This study examined whether practice with arithmetic problems presented in a nontraditional problem format improves understanding of mathematical equivalence. Children (M age = 8;0; N = 90) were randomly assigned to practice addition in one of three conditions: (a) traditional, in which problems were presented in the traditional "operations on left side" format (e.g., 9 + 8 = 17); (b) nontraditional, in which problems were presented in a nontraditional format (e.g., 17 = 9 + 8); or (c) no extra practice. Children developed a better understanding of mathematical equivalence after receiving nontraditional practice than after receiving traditional practice or no extra practice. Results suggest that minor differences in early input can yield substantial differences in children's understanding of fundamental concepts.  相似文献

Many schools are beginning to implement multi-tier response to intervention (RTI) models for the prevention of reading difficulties and to assist in the identification of students with learning disabilities (LD). The present study was part of our larger ongoing longitudinal RTI investigation within the Florida Learning Disabilities Center grant. This study used a longitudinal correlational design, conducted in 7 ethnically and socio-economically diverse schools. We observed reading instruction in 20 classrooms, examined response rates to kindergarten Tier 1 instruction, and predicted students' first grade reading performance based upon kindergarten growth and end of year reading performance (n = 203). Teachers followed an explicit core reading program and overall, classroom instruction was rated as effective. Results indicate that controlling for students' end of kindergarten reading, their growth across kindergarten on a variety of language and literacy measures suppressed predictions of first grade performance. Specifically, the steeper the students' trajectory to a satisfactory outcome, the less likely they were to demonstrate good performance in first grade. Implications for future research and RTI implementation are discussed.  相似文献

This paper uses one national case to illustrate how diverse ideological agendas of central state agencies contest the discursive space within which major education policy reforms are developed. In Aotearoa New Zealand in 1988, ‘self‐managed’ schools were promoted ostensibly to allow parents more say in their children’s education and local school administration. The Tomorrow’s Schools reform policy texts included an existing social democratic partnership rhetoric, positioning principals as professional leaders working collaboratively with elected parent boards of trustees. However, the new ideology of ‘parental choice’ of school within a local schooling marketplace, underpinned by a chief executive or market managerial model of principalship, was later operationalised through mechanisms of ‘steerage’ from the centre. To explain this shift, we examine selected policy text pre‐cursors to the reforms and identify how contrasting forms of ‘principal’ and ‘teacher’ identity emerged within social democratic, neo‐liberal and market managerial ideologies. We further show that while radical (Treasury) market liberal arguments for labour market deregulation and consumer choice failed to gain widespread support, the State Services Commission preferred market managerialist strategies for promoting public accountability of schools (based on aggregate student achievement outcome data and centrally determined national educational priorities) were successfully embedded during the 1990s.  相似文献

Research suggests that peer mentoring can positively impact on emotional literacy competencies. This study explored the effects of peer mentoring on the emotional literacy competencies of Year 7 peer mentees using a quasi-experimental pre-test and post-test control group design. Results supported the hypothesis that peer mentoring has a positive impact on the emotional literacy competencies of mentees with low to average levels of emotional literacy at pre-intervention. Results also showed a significant negative correlation between attendance at sessions and perceived Conduct Problems. Unexpectedly, results indicated adverse effects of reading mentoring on the emotional literacy competencies of control participants.  相似文献

The present work investigates the relations between amplitude and type of collaboration (intramural, extramural domestic or international) and output of specialized versus diversified research. By specialized or diversified research, we mean within or beyond the author’s dominant research topic. The field of observation is the scientific production over five years from about 23,500 academics. The analyses are conducted at the aggregate and disciplinary level. The results lead to the conclusion that in general, the output of diversified research is no more frequently the fruit of collaboration than is specialized research. At the level of the particular collaboration types, international collaborations weakly underlie the specialized kind of research output; on the contrary, extramural domestic and intramural collaborations are weakly associated with diversified research. While the weakness of association remains, exceptions are observed at the level of the individual disciplines.  相似文献

In classical model reference adaptive control (MRAC), the adaptive rates must be tuned to meet multiple competing objectives. Large adaptive rates guarantee rapid convergence of the trajectory tracking error to zero. However, large adaptive rates may also induce saturation of the actuators and excessive overshoots of the closed-loop system’s trajectory tracking error. Conversely, low adaptive rates may produce unsatisfactory trajectory tracking performances. To overcome these limitations, in the classical MRAC framework, the adaptive rates must be tuned through an iterative process. Alternative approaches require to modify the plant’s reference model or the reference command input. This paper presents the first MRAC laws for nonlinear dynamical systems affected by matched and parametric uncertainties that constrain both the closed-loop system’s trajectory tracking error and the control input at all times within user-defined bounds, and enforce a user-defined rate of convergence on the trajectory tracking error. By applying the proposed MRAC laws, the adaptive rates can be set arbitrarily large and both the plant’s reference model and the reference command input can be chosen arbitrarily. The user-defined rate of convergence of the closed-loop plant’s trajectory is enforced by introducing a user-defined auxiliary reference model, which converges to the trajectory tracking error obtained by applying the classical MRAC laws before its transient dynamics has decayed, and steering the trajectory tracking error to the auxiliary reference model at a rate of convergence that is higher than the rate of convergence of the plant’s reference model. The ability of the proposed MRAC laws to prescribe the performance of the closed-loop system’s trajectory tracking error and control input is guaranteed by barrier Lyapunov functions. Numerical simulations illustrate both the applicability of our theoretical results and their effectiveness compared to other techniques such as prescribed performance control, which allows to constrain both the rate of convergence and the maximum overshoot on the trajectory tracking error of uncertain systems.  相似文献
