ObjectiveTo examine the relationship between the use of preventive software on the home computer and unwanted exposure to sexual material online.MethodsThe Youth Internet Safety Survey-2 was a national, RDD telephone survey conducted in March–June 2005. Eight hundred households (one caregiver and one child between the ages of 10 and 17 years) with home Internet access answered questions pertaining to Internet prevention activities in the household and adolescent behaviors and exposures online.ResultsUnwanted exposure to sexual material occurred in 32% of youth in homes with pop-up/spam blockers and 25% of youth in homes with filtering, blocking, or monitoring software on the home computer, compared to 43% of households without preventive software installed on the home computer. Among otherwise similar youth, pop-up/spam blockers installed on the home computer were significantly associated with 59% lower odds of reporting unwanted exposure to sexual material on the home computer; and filtering, blocking, or monitoring software was significantly associated with 65% lower odds. When data were stratified by youth sex, associations between preventive software and unwanted exposure were similar for boys and girls. When stratified by age, preventive software was associated with significantly reduced risk of unwanted exposure for 10–12-year olds and 13–15-year olds, but not for 16–17-year olds.ConclusionAlthough these correlational analyses are far from providing conclusive evidence that preventive software protects children from unwanted exposure to sexual material online, findings suggest that caregivers of boys and girls 15 years of age and younger who want to reduce the likelihood of unwanted exposure to sexual material on the home computer should consider including preventive software—especially filtering, blocking, or monitoring software—in their Internet safety plan.Practice implicationsPractitioners should partner with caregivers in developing an Internet safety plan, including proactive caregiver-youth discussions about expected Internet behavior appropriate for their household.  相似文献   

Can Inquiry and Reflection be Contagious? Science Teachers, Students, and Action Research     

Kimberly Lebak  Ron Tinsley 《Journal of Science Teacher Education》2010,21(8):953-970

This study reports the transformations of 3 science teachers who conducted action research projects following a model, unique to our graduate program, which follows the theoretical tenets of adult and transformative learning theory. Teachers video their teaching, engage in weekly peer group collaborative reflection sessions, collaborate with students, and consult with other sources to identify goals for improving their teaching practices, develop action plans, and analyze the results of their actions. As a result of this process, all 3 teachers changed their pedagogical approach from a teacher centered textbook driven approach to a student centered inquiry based approach. Implications of using this model as a powerful means of professional development for science teachers are explored.  相似文献   

Disability in higher education: a position paper     

King LH  Aguinaga N  O'Brien C  Young W  Zgonc K 《American annals of the deaf》2010,155(3):386-391

Leadership in education, particularly special education, implies both knowledge and application of professional behaviors, decisions, and ethics within the field. University students look for best practices in education to be modeled by faculty; this, in turn, underscores a fundamental belief in inclusionary principles. Such modeling is important on every level in teacher education programs, particularly special education programs. The higher a student's level (i.e., undergraduate vs. doctoral), the more notice that student will take of disparities between rhetoric and actions. While reflective practices are explicitly taught in teacher preparation programs to enable professionals to reflect on their own personal and professional practices, teacher education faculty need to employ the same strategy to ensure that they are indeed modeling the practices they teach. This position paper documents the impressions of a doctoral cohort in special education in terms of inclusionary practices demonstrated in a real-life context.  相似文献   

A Small‐Scale Randomized Efficacy Trial of the Identity Project: Promoting Adolescents’ Ethnic–Racial Identity Exploration and Resolution          下载免费PDF全文

Adolescents’ ethnic–racial identity (ERI) formation represents an important developmental process that is associated with adjustment. The Identity Project intervention, grounded in developmental theory, was designed to engage adolescents in the ERI processes of exploration and resolution. The current small‐scale efficacy trial involved an ethnic–racially diverse sample of adolescents (N = 215; M_age = 15.02, SD = .68) from eight classrooms that were randomly assigned by classroom to the intervention or attention control group. Differences between conditions in ERI exploration at Time 2 were consistent with desired intervention effects; furthermore, higher levels of ERI exploration at Time 2 predicted increases in ERI resolution at Time 3 only for youth in the treatment condition. Findings provide preliminary evidence of program efficacy.  相似文献   

A Developmental Neuroscience Study of Moral Decision Making Regarding Resource Allocation          下载免费PDF全文

Kimberly L. Meidenbauer  Jason M. Cowell  Melanie Killen  Jean Decety 《Child development》2018,89(4):1177-1192

Distinguishing between equity and equality is essential when making social and moral decisions, yet the related neurodevelopmental processes are unknown. Evaluations of contextually based third‐party distributions incorporating recipient need and resource importance were examined in children and adolescents (N = 82; 8–16 years). Spatiotemporal neurodynamic responses show distinct developmental profiles to viewing such distributions. Event‐related potentials (ERPs) differentially predicted real‐life behaviors based on age, where older children's (8–10 years) evaluations were related to a fairly rapid, automatic ERP component (early posterior negativity), whereas adolescent and preadolescent (11–16 years) evaluations, first‐person allocations, and prosocial behaviors were predicted by later, cognitively controlled ERP components (P3 and late positive potential). Together, these results reveal age‐related changes regarding the neural responses that correspond to distributive justice decisions.  相似文献   

Failing with grace: kids,Improv and embodied literacies          下载免费PDF全文

Kimberly Lenters  Alec Whitford 《Literacy》2018,52(3):117-127

In this article, we explore the idea that comedy, with its often unorthodox ways of looking at, experiencing, and responding to the world, offers untold possibility for classroom literacy instruction. The article focuses on the potential of Improv comedy as socio‐materialist literacy in the classroom. It provides an account of Improv as a form of embodied literacy that operates as an assemblage created collectively between many people, practices, and material objects. We present findings from interviews with professional comedians regarding the possibilities of comedy for language and literacy instruction with elementary school children. The article then examines a moment from the subsequent classroom phase of the study to look at ways Improv can help students create stories and ways that laughter can be used to create a cohesive assemblage based around students' spontaneous creation of texts. The aim of the article is to provide educators with a practical means to apply socio‐materialist literacy in their classrooms through Improv, which will, in turn, allow students to create collectively generated texts and assemblages.  相似文献   

Beyond health messaging: a behavioural economics approach to increasing self-selected distance during an acute bout of cycling     

Aaron T. Piepmeier  Jennifer L. Etnier  Kimberly S. Fasczewski 《European Journal of Sport Science》2018,18(9):1264-1270

The purpose of this study was to explore the effects of the perceived purpose of exercising on the self-selected distance peddled during an acute cycling task. Participants were randomly assigned to one of three groups (health, wealth, charity). All participants watched a video emphasizing the health benefits of performing at least 30?min of daily exercise. Those in the health group were not provided any additional information. Those in the wealth group were then informed that they would earn money for every two kilometres cycled. Those in the charity group were informed that they would earn money for a charity for every two kilometres cycled. Participants were not given a time/distance limit and were instructed to cycle until they chose to stop. Analyses revealed that participants in the wealth and charity group cycled significantly farther than those in the health group (approximately twice as far). Additionally, a significant sex by group interaction showed that women cycled farther for charity while men cycled farther for wealth. These results suggest that health messages used to increase exercise behaviour may benefit from exploring how paradigms from behavioural economics influence behaviors that have relevance to public health.  相似文献   

Private Speech Moderates the Effects of Effortful Control on Emotionality     

Kimberly L. Day  Amy Neal  Julie C. Dunsmore 《Early education and development》2018,29(2):161-177

Research Findings: In addition to being a regulatory strategy, children’s private speech may enhance or interfere with their effortful control used to regulate emotion. The goal of the current study was to investigate whether children’s private speech during a selective attention task moderated the relations of their effortful control to their anger and sadness. The private speech of 156 preschoolers (age in months: M = 52.10, SD = 9.24, min = 36.20, max = 69.50) was transcribed and coded during a selective attention task. Effortful control was observed and reported by parents. Anger and sadness were reported by parents and observed in a frustration task. Children who used more inaudible muttering had higher levels of sadness. Effortful control interacted with private speech to explain anger. The negative relation of effortful control to anger was significant for children who used low and moderate but not high levels of task-irrelevant private speech. Practice or Policy: The presence of private speech, although it may support regulatory abilities within a task, may be an additional form of evaluation that might help teachers and caregivers decide how best to support children’s learning. These findings suggest that private speech can be used as an indicator of how well children use other regulatory abilities, such as effortful control.  相似文献
