Heavy parent digital technology use has been associated with suboptimal parent–child interactions, but no studies examine associations with child behavior. This study investigates whether parental problematic technology use is associated with technology‐based interruptions in parent–child interactions, termed “technoference,” and whether technoference is associated with child behavior problems. Parent reports from 170 U.S. families (child Mage = 3.04 years) and actor–partner interdependence modeling showed that maternal and paternal problematic digital technology use predicted greater technoference in mother–child and father–child interactions; then, maternal technoference predicted both mothers’ and fathers’ reports of child externalizing and internalizing behaviors. Results suggest that technological interruptions are associated with child problem behaviors, but directionality and transactional processes should be examined in future longitudinal studies.  相似文献

In this mixed-methods study, we examine the potential of place-based stewardship education (PBSE) for nurturing rural students’ community attachment and aspirations to contribute to the preservation of the environmental “commons.” Analyzing pre- and post-experience surveys (n = 240) and open-ended responses (n = 275) collected from middle school students in a Northeast Michigan school district, we found significant increases in students’ environmental sensitivity, environmentally responsible behaviors, community attachment, and confidence in their capacities for civic action. Analyses of open-ended responses pointed to the potential of PBSE to nurture students’ identification with their community and to increase their commitment to stewardship of their community's natural resources. This study makes a unique contribution to the literature on rural schools by focusing on the environmental commons and younger generations’ commitments to preserve it as an asset of rural communities. By linking students’ learning with collective action to preserve the environmental commons, PBSE can expand students’ aspirations for the kind of world they want to live in and the roles they might play in it.  相似文献

This project developed and studied The Source, an alternate reality game (ARG) designed to foster interest and knowledge related to science, technology, engineering, and math (STEM) among youth from populations underrepresented in STEM fields. ARGs are multiplayer games that engage participants across several media such as shared websites, social media, personal communications, and real-world settings to complete activities and collaborate with team members. The Source was a five-week summer program with 144 participants from Chicago aged 13 to 18 years. The Source incorporated six socio-contextual factors derived from three frameworks: Chang’s (ERIC Digest, 2002) recommendations for engaging underrepresented populations in STEM careers, Lave and Wenger’s (Cambridge University Press, 1991) situated learning model, and Barron’s (Human Development, 49(4); 193-224, 2006) learning ecology perspective. These factors aligned with the program’s aims of promoting (1) social community and peer support, (2) collaboration and teamwork, (3) real-world relevance and investigative learning, (4) mentoring and exposure to STEM professionals, (5) hands-on activities to foster transferable skill building, and (6) interface with technology. This paper presents results from 10 focus groups and 10 individual interviews conducted with a subset of the 144 youth participants who completed the game. It describes how these six factors were realized through The Source and uses them as a lens for considering how The Source functioned pedagogically. Qualitative findings describe youth’s perception of The Source’s potential influence on STEM interest, engagement, and identity formation. Despite limitations, study results indicate that underrepresented youth can engage in an immersive, narrative, and game-based experience as a potential mechanism for piquing and developing STEM interest and skills, particularly among underrepresented youth.  相似文献

This article documents the critical friendship of an experienced teacher educator and a doctoral student through our joint exploration of student teaching supervision. By adopting a co/autoethnographic approach, we learned from biographical and contemporaneous critical incidents that informed short- and long-term practices. In particular, we learned about supervision from our experiences as student teachers, mentors, and university supervisors. We learned about supervision through experiences and insights as they occurred and from the relational dynamics provided by our critical friendship. We dissect critical moments that resulted in a series of key understandings. Autobiography informs practice: in sharing our biographies, we developed an understanding and vision for the type of supervision practice we wished to enact. Reflection and discussion inform practice: by journaling and discussing the supervision process, we reconsidered and acted upon practice. Finally, critical friends provide transformative insights into practice: we learned from each other through interaction and critique of past actions, current practices and future actions. Our collaboration was instrumental in providing a vision that defined our individual pedagogies of supervision. Consistent with other scholarship on the learning of student teacher supervision, this article promotes the provision of a support space for both novice and experienced supervisors to deconstruct and improve practice.  相似文献

Objective

The goal of this study was to investigate the adverse childhood experiences (ACEs) in youth in a low-income, urban community.

Study design

Data from a retrospective chart review of 701 subjects from the Bayview Child Health Center in San Francisco are presented. Medical chart documentation of ACEs as defined in previous studies were coded and each ACE criterion endorsed by a traumatic event received a score of 1 (range = 0-9). This study reports on the prevalence of various ACE categories in this population, as well as the association between ACE score and two pediatric problems: learning/behavior problems and body mass index (BMI) ≥ 85% (i.e., overweight or obese).

Results

The majority of subjects (67.2%, N = 471) had experienced 1 or more categories of adverse childhood experiences (ACE ≥ 1) and 12.0% (N = 84) had experienced 4 or more ACEs (ACE ≥ 4). Increased ACE scores correlated with increased risk of learning/behavior problems and obesity.

Conclusions

There was a significant prevalence of endorsed ACE categories in this urban population. Exposure to 4 or greater ACE categories was associated with increased risk for learning/behavior problems, as well as obesity.

Practice implications

Results from this study demonstrate the need both for screening of ACEs among youth in urban areas and for developing effective primary prevention and intervention models.  相似文献

The work of teacher education during student teaching typically takes place in two distinct “spaces”: placement sites and college/university settings. The program featured in this article is structured in ways that clearly mark out those two spaces. Yet this configuration led our university supervisors, whose work primarily took place in the field, to feel like “outsiders.” To redress this concern, a third learning space was incorporated into our student teaching seminar. We suggest that “third spaces” in combination with return-to-campus courses not only mitigates the peripherality of university supervisors, but also amplifies the influence of a teacher preparation program.  相似文献

The purpose of this study is to develop and validate a new instrument to measure the multidimensional nature of motivations to engage in healthy behavior practices among older adults. The Healthy Aging Incentives Scale (HAIS) was developed empirically from data collected from 158 older adults participating in a health and wellness clinic located within a multipurpose senior center in the United States. A factor analysis of the HAIS revealed five themes prompting older adults to participate in health aging practices: health and fitness, psychological well-being, locus of control, social functions, and socialization attributes. Additional data are provided that support reliability and validity of the HAIS including convergent validity of the 20-item scale by its correlation with healthy behavior habits. Conclusions are drawn showing literature support for the multidimensional scale and the important determinants for promoting healthy outcomes for this population.  相似文献

Purpose: The purpose of this study was to characterize pelvic displacement and cardiorespiratory responses to simulated horseback riding and walking in youth with cerebral palsy and to compare responses to youth without cerebral palsy before and after 8 weeks of hippotherapy. Method: Eight youth with cerebral palsy (Mage = 10 ± 4 years; Mheight = 137 ± 24 cm; Mweight = 32 ± 16 kg) and 8 youth without cerebral palsy (Mage = 11 ± 2 years; Mheight = 149 ± 14 cm; Mweight = 48 ± 15 kg) underwent a hippotherapy intervention. Participants completed simulated horseback riding at an intensity approximating a fast walk (0.65 Hz) and walked on a treadmill (1 mph, 0% grade) before and after hippotherapy. Pelvic displacement along the anterior-posterior, vertical, and medial-lateral axes, heart rate, oxygen consumption, ventilation, and blood pressure were measured at rest and during steady-state exercise in both exercise modes. Results: Kinematics and cardiorespiratory responses were similar between the 2 groups during simulated horseback riding (p > .05 for all) before the intervention. Significantly greater cardiorespiratory responses were observed in the youth with cerebral palsy compared with the group without cerebral palsy while walking before and after the intervention (p < .05, effect sizes 26% to 237% greater). Eight weeks of hippotherapy did not alter responses, but anecdotal improvements in gait, balance, posture, and range of motion were observed in those with cerebral palsy. Conclusion: These results contribute to our understanding regarding the efficacy of hippotherapy as an intervention to improve functional abilities in those with cerebral palsy.  相似文献
