Daylong at-home audio recordings from 10 Tseltal Mayan children (0;2–3;0; Southern Mexico) were analyzed for how often children engaged in verbal interaction with others and whether their speech environment changed with age, time of day, household size, and number of speakers present. Children were infrequently directly spoken to, with most directed speech coming from adults, and no increase with age. Most directed speech came in the mornings, and interactional peaks contained nearly four times the baseline rate of directed speech. Coarse indicators of children’s language development (babbling, first words, first word combinations) suggest that Tseltal children manage to extract the linguistic information they need despite minimal directed speech. Multiple proposals for how they might do so are discussed. 相似文献

This paper presents evidence from a unique reform model that allowed teachers and other educators in a large urban district to collaborate with one another in the development of an innovation meant to improve student ownership and responsibility. In this longitudinal case study, we describe school stakeholders’ learning about the design, the process of knowledge-transfer to school teams, and how school teams shared their ongoing learning with one another. School implementation teams were initially reluctant to share their learning with one another. By engaging in a shared innovation development process with structures for routine sharing, over time, implementation team members were increasingly interested in sharing their learning with one another. We discuss the implications for school improvement efforts. 相似文献

Mentoring in Teacher Education is a key component in the professional development of student teachers. However, little research focuses on the knowledge shared and generated in mentoring conversations. In this paper, we explore the knowledge student teachers articulate in mentoring conversations under three different post-lesson approaches to mentoring: dialogue journaling, regular conferences and stimulated-recall conferences. Propositional discourse analysis identified 4534 propositions that were subsequently classified into four types of knowledge: recalls, appraisals, rules and artefacts along with the precision of arguments therein. Additionally, log-linear analyses were conducted to search for differences among the three mentoring approaches. The results indicate that dialogue journaling demonstrated more appraisals of practice, regular conferences emphasised rules and artefacts, and stimulated-recall favoured more precision in the type of the arguments stated. The three mentoring styles favour different but complementary understandings of practice and point to the impact of various approaches to mentoring on the sort of knowledge shared and generated in post-lesson mentoring conferences. 相似文献

The conventional approach to scaling up educational reforms considers the development and testing phases to be distinct from the work of implementing at scale. Decades of research suggest that this approach yields inconsistent and often disappointing improvements for schools most in need. More recent scholarship on scaling school improvement suggests that these activities should be integrated into implementation, although this presents challenges in how we evaluate implementation in particular schools. This paper presents a framework to conceptualize implementation when design, implementation, and scaling up are integrated activities. 相似文献

This study examined the effect of imagery interventions for the presentation of novel science vocabulary to fifth grade learners. Eighty-nine students from two schools in Long Island participated in this study and were randomly assigned to four different instructional interventions: a Picture Presentation method, in which a word was paired with a picture; an Image Creation??No Picture method, in which the participants were told to create an image of the word and draw it on paper; an Image Creation??Picture method, in which the students were presented with the picture and then told to draw it; and a Word Only method, which involved the simple verbal presentation of the word. Results demonstrated that students in the imagery intervention groups (Picture Presentation, Image Creation??No Picture, and Image Creation??Picture) scored higher on the outcome measures at both immediate and delayed recall. It was also shown that the deeper the students processed the ??to be learned?? vocabulary words, the higher they scored on the outcome measures. Based on the mean outcome measure scores at both time points, students in the Image Creation??Picture intervention scored the highest, followed by the students in the Image Creation??No Picture intervention, those in the Picture Presentation intervention, and finally the Word Only intervention students. Such a study has implications as to the most effective way to integrate science and literacy and successfully present novel concepts in the classroom. 相似文献

School innovation in district context: Comparing traditional public schools and charter schools 总被引：1，自引：0，他引：1
Market reforms in education are part of the educational policy landscape in many countries. Central to arguments for market reforms is the idea that competition and choice will spur changes in schools to be more innovative, which in turn will lead to better student outcomes. We define innovation in terms of a practice's relative prevalence in a local district context. A charter school is innovative in its use of a practice if the traditional public schools in its local school district are not using that practice. We explore factors based on arguments for charter schools that may affect a charter schools’ propensity toward innovation to explain variation in levels of innovation across charter schools. We find that, on the whole, charter schools do not fulfill their promise of innovation. Teacher tenure is the most notable exception. Parental involvement is the only characteristic of charter schools that significantly predicts variation in levels of organizational innovativeness. 相似文献

In the midst of a generalised HIV and AIDS epidemic in southern Africa, the argument for more coordinated and comprehensive youth sexual health interventions is intensifying. Yet the crucial question of how best to provide young people with these skills and knowledge remains a key challenge for policy-makers, researchers and practitioners in our region. Moreover, amongst the available literature on sex education in southern Africa, few authors have taken an applied perspective, to look at fresh approaches and tools with the potential to be implemented more broadly. This paper argues for a greater focus on concepts of masculinity and sexuality in the development of sexual health efforts in southern Africa. It aims to bridge theory and practice by advancing six promising approaches with the potential to create a suitable space and environment for participants to engage with these issues. Approaches include methods and tools currently being implemented in existing programmes, as well as ideas emerging from recent literature. Our paper is ultimately a call for further ‘out-of-the-box’ thinking to find more effective and creative practical ways of providing the sexual health education our region's youth urgently needs. It is also a call for more applied research, to better inform future sex education programmes in southern Africa. 相似文献

We explored the experiences and emotions women expressed about having a blood clot, including revelations about family members' decision to avoid disclosing inherited risk for clotting. We do this through analysis of in-depth life reflection interviews (N = 20) of women who experienced a first venous blood clot between the ages of 18 and 50 years. Selective coding reduced the data to an overarching story associated with thrombosis survivorship and loss across multiple life domains. The themes identified include participant revelations about living in the shadow of genetic susceptibility for thrombosis. Participants manage changes associated with lingering health effects, and daily routines for work and life, adapting their lives to manage coagulability. A second theme reveals the fallout linked to the severity of thrombosis encompassed in haunting psychological scenarios, persistent emotional concerns, and social discrimination. Participants assumed responsibility to disclose inherited risk, with the women expressing empowerment in knowing risks and acknowledging possible genetic testing mistakes. The overarching perspective was one of hope through proactive actions in occupational, recreational, and relational realms. We offer our findings as a theoretical depiction of thrombosis survivor identity and the need for public health and clinical communication to support disclosing family history for clotting. 相似文献
