Visual input during development seems crucial in tactile spatial perception, given that late, but not congenitally, blind people are impaired when skin‐based and tactile external representations are in conflict (when crossing the limbs). To test whether there is a sensitive period during which visual input is necessary, 14 children (age = 7.95) and a teenager (LM; age = 17.38) deprived of early vision by cataracts, and whose sight was restored during the first 5 months and at age 7, respectively, were tested. Tactile localization with arms crossed and uncrossed was measured. Children showed a crossing effect indistinguishable from a control group (Ns = 28, age = 8.24), whereas LM showed no crossing effect (Ns controls = 14, age = 20.78). This demonstrates a sensitive period which, critically, does not include early infancy. 相似文献

Research Findings: Pretend play is an essential part of child development and adjustment. However, parents, teachers, and researchers debate the function of aggression in pretend play. Different models of aggression predict that the expression of aggression in play could either increase or decrease actual aggressive behavior. The current study examined pretend play and classroom behavior in preschoolers. Children (N = 59) were administered a measure of pretend play, and teacher ratings of classroom behavior were obtained. Pretend play skills were positively associated with prosocial behavior in the classroom and negatively associated with physical aggression in the classroom. In particular, expression of oral aggression in play related to less physical aggression and more prosocial behavior in the classroom. Practice or Policy: These findings suggest that pretend play should be encouraged, as these skills relate to positive behaviors in the classroom. In addition, it was found that aggression in pretend play was not an indicator of actual aggressive behavior, as it related to positive behaviors in the classroom. Implications for parents and teachers are discussed. 相似文献

Lesbian, gay, bisexual, transgender, queer, questioning, intersex, asexual, and ally (LGBTQQIAA) students are not commonly discussed in teacher education programs. Issues related to LGBTQQIAA learners need to be addressed in schools and in teacher education programs. Extant research shows that LGBTQQIAA students often face hostile school climates, with few resources and little support, which can lead to higher levels of absence and truancy, lower levels of academic achievement, and numerous negative health outcomes. This article uses autoethnographic methods to examine the experiences of an activist group working with preservice teachers, teacher educators, and other social justice advocates on a long-term service project for undergraduate teacher candidates aimed at increasing recognition of and giving voice to K—12 LGBTQQIAA students' experiences. Issues related to agency and resistance are addressed, and implications for teacher preparation programs are discussed. 相似文献

This study examines the evolution of 11 prospective teachers’ understanding of mathematical modeling through the implementation of a modeling module within a curriculum course in a secondary teacher preparation program. While the prospective teachers had not previously taken a course on mathematical modeling, they will be expected to include modeling as part of the school curriculum under current state standards. The module consisted of readings, analysis of the Common Core State Standards, carefully designed modeling activities, individual and group work, discussion, presentations, and reflections. The results show that while most prospective teachers had misconceived definitions of mathematical modeling prior to the module, they developed the correct understanding of modeling as an iterative process involving making assumptions and validating conclusions connected to everyday situations. The study reveals how the prospective teachers translated the modeling cycle into practice in the context of a carefully designed open-ended problem and the strong connections between modeling activities and promoting mathematical practices. 相似文献

Doula Support and Attitudes of Intrapartum Nurses: A Qualitative Study from the Patient's Perspective 
下载免费PDF全文
下载免费PDF全文 Although the roles of the intrapartum nurse and professional doula differ markedly, they serve women best if their roles complement each other. For doulas and nurses to work well together in order to facilitate a positive birth experience for the patient, they would logically need to develop a relationship based on mutual respect. The purpose of this pilot qualitative study was to examine the level of acceptance shown by intrapartum nurses for doula support, as perceived by the parturient woman. Implications for further research are addressed. 相似文献

Moderate physical exercise acts at molecular and behavioural levels, such as interfering in neuroplasticity, cell death, neurogenesis, cognition and motor functions. Therefore, the aim of this study is to analyse the cellular effects of moderate treadmill running upon substantia nigra during early neurodegeneration. Aged male Lewis rats (9-month-old) were exposed to rotenone 1mg/kg/day (8 weeks) and 6 weeks of moderate treadmill running, beginning 4 weeks after rotenone exposure. Substantia nigra was extracted and submitted to proteasome and antioxidant enzymes activities, hydrogen peroxide levels and Western blot to evaluate tyrosine hydroxylase (TH), alpha-synuclein, Tom-20, PINK1, TrkB, SLP1, CRMP-2, Rab-27b, LC3II and Beclin-1 level. It was demonstrated that moderate treadmill running, practiced during early neurodegeneration, prevented the increase of alpha-synuclein and maintained the levels of TH unaltered in substantia nigra of aged rats. Physical exercise also stimulated autophagy and prevented impairment of mitophagy, but decreased proteasome activity in rotenone-exposed aged rats. Physical activity also prevented H2O2 increase during early neurodegeneration, although the involved mechanism remains to be elucidated. TrkB levels and its anterograde trafficking seem not to be influenced by moderate treadmill running. In conclusion, moderate physical training could prevent early neurodegeneration in substantia nigra through the improvement of autophagy and mitophagy. 相似文献

Through our understanding of decolonizing Hispanophone curriculum, our synoptic rendering seeks to better situate US-based research on testimonio within Latin American literary traditions. Specifically, we provide a synoptic rendering that outlines the testimonio tradition’s literary criticism and an analysis of key testimonio texts. Of particular emphasis in our analysis, we provide representations from Latin American testimonio traditions’ sociological, journalistic, fictionalized, and poetic dimensions. Our synoptic rendering concludes with implications for the advancement of testimonio traditions in education research with emphasis on testimonio resources for Latin@ graduate students. 相似文献
