Sperry, Sperry, and Miller (2018) aim to debunk what is called the 30-million-word gap by claiming that children from lower income households hear more speech than Hart and Risley (1995) reported. We address why the 30-million-word gap should not be abandoned, and the importance of retaining focus on the vital ingredient to language learning—quality speech directed to children rather than overheard speech, the focus of Sperry et al.'s argument. Three issues are addressed: Whether there is a language gap; the characteristics of speech that promote language development; and the importance of language in school achievement. There are serious risks to claims that low-income children, on average, hear sufficient, high-quality language relative to peers from higher income homes.  相似文献

Children with severe to profound intellectual disability have been excluded from education on the basis that their impairment makes them ‘ineducable’. The Western Cape Forum for Intellectual Disability challenged this notion through litigation against the South African Government. The ensuing judgement asserts the right to education of these children and outlines action steps for government to this end. We describe the actions taken by the Western Cape Education Department in responding to the requirements of the court by means of a document review. We then reflect on the implementation process, highlighting key learning points of relevance for others engaged in implementation. We note critical factors to be considered for the child, their families, special care centres, and the broader educational and legal systems. We conclude by outlining important considerations for the inclusion of these children within the education system in South Africa.  相似文献

Science educators have the common goal of helping students develop scientific literacy, including understanding of the nature of science (NOS). University faculties are challenged with the need to develop informed NOS views in several major student subpopulations, including science majors and nonscience majors. Research into NOS views of undergraduates, particularly science majors, has been limited. In this study, NOS views of undergraduates in introductory environmental science and upper-level animal behavior courses were measured using Likert items and open-ended prompts. Analysis revealed similarities in students'' views between the two courses; both populations held a mix of naïve, transitional, and moderately informed views. Comparison of pre- and postcourse mean scores revealed significant changes in NOS views only in select aspects of NOS. Student scores on sections addressing six aspects of NOS were significantly different in most cases, showing notably uninformed views of the distinctions between scientific theories and laws. Evidence-based insight into student NOS views can aid in reforming undergraduate science courses and will add to faculty and researcher understanding of the impressions of science held by undergraduates, helping educators improve scientific literacy in future scientists and diverse college graduates.  相似文献

Trauma symptoms among infants exposed to intimate partner violence   总被引:5,自引:0,他引:5  
OBJECTIVE: To determine whether infants have a traumatic response to intimate partner violence (male violence toward their female partner; IPV) experienced by their mothers, two questions were explored: (1) Is the number of infant trauma symptoms related to the infant's temperament and the mother's mental health? (2) Does severity of violence moderate those relationships? METHODOLOGY: Forty-eight mothers reported whether their 1-year-old infants experienced trauma symptoms as a result of witnessing episodes of IPV during their first year of life. Mothers also reported on their own trauma symptoms that resulted from experiences of IPV. RESULTS: For those infants experiencing severe IPV and whose mothers exhibit trauma symptoms, we were able to predict whether infants exhibited trauma symptoms (b = .53, p < .01). This was not true for children who witnessed less severe IPV (b= -.14, ns). Maternal depressive symptoms and difficult infant temperament did not predict infant trauma symptoms for either group of infants. CONCLUSION: Mothers report that infants as young as 1-year-old can experience trauma symptoms as a result of hearing or witnessing IPV. The significant relationship between infant and maternal trauma symptoms, especially among those infants experiencing severe IPV, are consistent with the theory of relational PTSD. Findings suggest that interventions for mothers and families need to consider the influence of the severity of IPV on very young children.  相似文献

This study follows an ethnically and economically diverse sample of 33 high school students to explore why some who were once very interested in science, engineering, or medicine (SEM) majors or careers decided to leave the pipeline in high school while others persisted. Through longitudinal interviews and surveys, students shared narratives about their developing science identities, SEM participation and aspirations. In analysis, three groups emerged (High Achieving Persisters, Low Achieving Persisters, and Lost Potentials), each experiencing different interactions and experiences within science communities of practice in and outside of school and within the extended family. These different microclimates framed students' perceptions of their SEM study, abilities, career options, and expected success, thereby shaping their science identities and consequent SEM trajectories. School science was often hard and discouraging; there were very few science advocates at school or home; and meaningful opportunities to work with real science professionals were scarce, even in schools with science or health academies. Students expressed positive attitudes toward science and non‐science pursuits where they experienced success and received support from important people in their lives. Results underscore the key role communities of practice play in career and identity development and suggest a need for interventions to help socializers better understand the value and purpose of science literacy themselves so as to encourage students to appreciate science, be aware of possible career options in science and enjoy learning and doing science. © 2009 Wiley Periodicals, Inc.

Teachers’ psychological well‐being is important for teachers and students, but teaching is highly stressful, particularly in special education. We examined the role of experiential avoidance (EA) in the well‐being of 529 middle and elementary school teachers. EA involves the tendency to avoid thoughts, feelings, and other internal experiences, even when doing so causes long‐range consequences. Using a teacher‐specific measure, we investigated EA's relationship to stress associated with student misbehavior and limited social support. We also assessed EA's relationship to burnout and depression, finding EA significantly and moderately correlated with depression and all scales of Maslach's Burnout Inventory. Mediation analyses showed EA mediated the relationship between stress associated with student behavior and measures of well‐being. We found 26.8% of teachers to be mildly, 8.9% moderately, and 2.8% moderately severely or severely depressed. This evidence concurs with studies showing the value of mindfulness‐based interventions and points to the utility of implementing interventions aimed at decreasing EA in teachers.  相似文献
