Although one might expect parents’ mind-mindedness (MM; the propensity to view children as mental agents) to relate to everyday mental-state talk (MST) and theory-of-mind capacity, evidence to support this view is lacking. In addition, both the uniqueness and the specificity of relations between parental MM, parental MST, and children's false belief understanding (FBU) are open to question. To address these three gaps, this study tracked 117 preschoolers (60 boys) and their parents across a 13-month period (Mage = 3.94 years, SD = 0.53, at Time 1). Parental MM, MST, and theory-of-mind capacity showed little overlap. Both MM and MST were weakly associated with children's concurrent FBU, but in line with social constructivist accounts, only MST predicted later FBU. 相似文献

Four meta-analyses were conducted to examine the magnitude of sex differences in self-estimates of general, mathematical/logical, spatial and verbal abilities. For all but verbal ability males gave significantly higher self-estimates than did females. The weighted mean effect size d for general intelligence was .37, for mathematical .44, for spatial .43 and for verbal .07. As these were significantly heterogeneous, homogeneity analysis was performed to identify moderating factors. These included age, instruction type, country and dominating author's gender. The outcomes were discussed in terms of possible causes of this phenomenon and some concerns about the interpretation of the results were raised. 相似文献

The first comprehensive national survey of all academic libraries in the United States which were conducting chat reference service was carried out to determine: what practices were being used to prepare personnel for chat reference service, what competencies were being taught, how and why training practices may have changed over time, and what modifications to current training practices were anticipated in the future. 相似文献

The purpose of this paper was to establish the variability and typical error of kinematic and kinetic variables representing the maximal instep kick in soccer for both the kicking and support legs. Ten skilled (good amateur or semi-professional) soccer players performed 20 maximal instep kicks of a stationary ball into a goal mouth. Motion of the kicking and support legs was recorded by an optoelectronic motion analysis system, and a six degrees of freedom model was used to compute kinematic and kinetic variables. Participants repeated the kicks on a second day at least 1 week later. The mean within-subject coefficient of variation across the kinematic and kinetic variables, trials, and days was 16% and did not change substantially as trial number increased or between day of test. Increasing trial number reduced the typical error (as determined by the standard error of the mean) such that for 20 trials 75% of the variables were below an arbitrary 5% threshold. It was concluded that for kicking investigations, 10–15 trials could be used and typical errors of 5% should be expected. 相似文献

Student populations in higher education in Australia and elsewhere in the developed world have experienced significant diversity over the past two decades. The existing literature has provided limited clarity about the effects of this diversity on the dimensions underpinning students' study philosophy domain. Based on a large data set from a leading Australian university, this paper analyses students' study philosophy, beliefs and attitudes towards teaching and learning. Factor analysis explored themes (or dimensions) within the survey. Multivariate analysis of variance used these dimensions as dependent variables with age, sex, ethnicity, study discipline, study level, academic performance and sex/ethnicity interaction as grouping variables to identify significant sources of variations. Deep learning, expediency and responsibility reflected the students' study philosophy domain. Deep learning and responsibility varied with ethnicity and academic performance. Expediency differed according to ethnicity, study discipline and academic performance. Students in business-related disciplines displayed greater expediency than peers elsewhere, treating education like any other commodity. The contribution of this study lies in its rigorous analysis of the impact of the diversity of the student population on the study philosophy domain, compared to the existing literature. 相似文献

The widespread adoption of information and communications technologies (ICT) in higher education (HE) since the mid 1990s has failed to produce the radical changes in learning and teaching than many anticipated. Activity theory and Rogers’ model of the adoption of innovations provide analytic frameworks that help develop our understanding of the actual impact of ICT upon teaching practices. This paper draws on a series of large‐scale surveys carried out over a 10 year period with distance education tutors at the UK Open University to explore the changing role of ICT in the work of teachers. It investigates how HE teachers in one large distance learning university have, over time, appropriated ICT applications as teaching tools, and the gradual rather than revolutionary changes that have resulted. 相似文献

The purpose of this study was to pilot an alternative student teaching supervision model at a college of education in a US context. In the study, the collaborators used multiple paired dyads to supervise student teachers with multiple supports from college faculty. This study examined how teachers and university faculty planned the use of paired dyads and how participants responded to the innovation. The findings suggest teachers and junior faculty can undertake bottom-up reform within larger systemic constraints. 相似文献
