Recent developmental cognitive neuroscience research has supported the notion that puberty and adolescence are periods of profound socio-emotional development. The current study was designed to investigate whether the onset of puberty marks an increase in the awareness of complex, or “mixed,” emotions. Eighty-three female participants (aged 9–16 years) were divided into three groups according to a self-report measure of puberty stage (early-, mid- and post-puberty). Participants were presented with emotional scenarios, and used four linear scales to rate their emotional response to each scenario. Scenarios were designed to evoke social emotions (embarrassment or guilt) or basic emotions (anger or fear), where social emotions are defined as those which require the representation of others' mental states. We measured the relative complexity or “mixedness” of emotional responses, that is, the degree to which participants reported feeling more than one emotion for a given scenario. We found that mixed emotion reporting increased between early- and post-puberty for social emotion scenarios, and showed no relationship with age, whereas there was no change in mixed emotion reporting for basic emotion scenarios across age or puberty groups. This suggests that the awareness of mixed emotions develops during the course of puberty, and that this development is specific to social emotions. Results are discussed in the context of brain development across puberty and adolescence, with speculation regarding the potential implications for education.  相似文献

Children's informal and formal learning experiences with geometric shapes currently result in misconceptions that persist into adulthood. Here, we combine research from mathematics education as well as cognitive science pertaining to concepts, categories, and learning strategies to propose a more optimal progression that is better specified and justified than the current standards. To do so, we reframed what constitutes a “simple” shape from perceptual simplicity to simplicity of properties. Our Property-Based Shape Sequence uses property-based criteria of what makes shapes “simple” and progresses in a way that affords opportunities for learners to develop hierarchical conceptions of two-dimensional and three-dimensional shapes. Our goals are threefold: (1) recommend an optimal, mathematically-correct shape learning sequence, (2) correct misconceptions that adults and children harbor about shapes, and (3) encourage cross-disciplinary collaborations between mathematics education and psychology researchers to validate the proposed learning sequence.  相似文献

This study examined interparental conflict as a curvilinear predictor of children's reactivity to interparental conflict and, in turn, their school problems across three annual measurements. Participants included 243 preschool children (Mage = 4.60 years; 56% girls) and their parents from racially (e.g., 48% Black; 16% Latinx) diverse backgrounds. Interparental conflict was a significant quadratic predictor of children's emotional reactivity (β = .23) and behavioral dysregulation (β = .27) to conflict over a 1-year period. The robust association between interparental conflict and behavioral dysregulation weakened at high levels of interparental conflict. In contrast, interparental conflict more strongly predicted children's emotional reactivity as conflict exposure increased. Children's emotional reactivity, in turn, predicted their greater school problems 1 year later (β = .25).  相似文献

In this article, we argue that teaching is and should be a central element to learning to teach, particularly as teacher education once again turns toward practice. From this perspective, we must elaborate how such a shift addresses the need to bridge the gap between knowledge for teaching and knowledge from teaching, between theory and practice, and among university courses and fieldwork. If the intent of such a shift is to fundamentally change the preparation of teachers, we argue that it requires teacher education programs to do more than increase the amount of time candidates spend in clinical field placements. It requires, we argue, that teacher educators engage in simultaneous innovation in three related, but distinct aspects of program design and implementation: organizational structures and policies, content and curriculum, and teacher education pedagogy. Without such dynamic engagement, the practice-turn will go the way of many past reforms in teacher education—it will be symbolic but not significant or meaningful.  相似文献

The study included an assessment of doctoral students, graduate faculty, and curriculum considerations to determine the degree of infusion of research integrity and responsible conduct of research (RCR) principles within a Doctor of Education program. Study results showed substantial increases in doctoral candidates’ knowledge levels of RCR, and faculty members serving as dissertation committee chairs reported greater understanding of RCR tenets than did non-dissertation chairs. The study also revealed a strong presence of research within the Ed. D. core curriculum.  相似文献

This study evaluated the types and frequencies of pre-examination errors recorded in the chemical pathology laboratory at the University Hospital of the West Indies, Jamaica. This was a retrospective analysis of errors recorded over a three year period. Data analysis was done on an average of 519,084 samples collected and tested per year. Samples included blood, urine, stool and other fluids. Pre-examination errors were identified and recorded following visual inspection of the samples and corresponding request forms by laboratory staff, then subsequently by the Senior Medical Technologist. Errors were generally classified as inappropriate sample (58 %), inappropriate form (23.4 %), inappropriate sample volume (9.3 %) and inappropriate sample tube (9.3 %). Over 90 % of recorded pre-examination errors were related to blood samples while urine samples accounted for 6.8 % error. Pre-examination errors were lower at this study location than elsewhere. Measures aimed at reducing instances of these errors are recommended for improved laboratory quality output.  相似文献

Abstract

The aim of this study was to determine if critical parameters for elite performance could be identified among a population of female shot putters. The performance of seven of the top women shot putters competing at the 2002 USA National Championships was examined. Video data were captured using two Panasonic 60 Hz cameras and the best throws of each athlete were digitized and analyzed using a Peak Motus three‐dimensional motion analysis system. Thirty variables were examined for their effect on the distance of the throw. Correlation analysis indicated that measured distance was positively correlated with release speed (r = 0.97, p < 0.0003) and shoulder‐hip separation (r = 0.72, p < 0.06) and negatively correlated with release angle (r = ‐0.74, p < 0.056), rear knee angle at rear foot touchdown (r = ‐0.93, p < 0.003) and rear knee angle at release (r = ‐0.76, p < 0.047). Greater knee flexion angle at both rear foot touch down and release along with a neutral shoulder‐hip angle at release were identified as the most critical parameters for success among this sample of elite women shot putters. The unique observation about the knee positions at specific events should assist in new training and coaching developments.  相似文献
