Narrative media health messages have proven effective in preventing adolescents' substance use but as yet few measures exist to assess perceptions of them. Without such a measure it is difficult to evaluate the role these messages play in health promotion or to differentiate them from other message forms. In response to this need, a study was conducted to evaluate the Perception of Narrative Performance Scale that assesses perceptions of narrative health messages. A sample of 1185 fifth graders in public schools at Phoenix, Arizona completed a questionnaire rating of two videos presenting narrative substance use prevention messages. Confirmatory factor analyses were computed to identify the factor structure of the scale. Consistent with prior studies, results suggest a 3 factor structure for the Perception of Narrative Performance Scale: interest, realism, and identification (with characters). In addition, a path analysis was performed to test the predictive power of the scale. The analysis shows that the scale proves useful in predicting intent to use substances. Finally, practical implications and limitations are discussed. 相似文献

This study features use of case-based pedagogy as a context for exploring science teacher education reform. A central premise of the study is that science teacher education reform is a complex process characterised by the individual and collective narrative histories of teachers. The study was conducted at West Visayas State University in the Philippines as a collaborative research endeavour involving two US and four Filipino science teacher educators. The centrepiece of this study was a case experience prompted by reflection on prospective and practicing elementary teachers' written cases. Results of the study are presented here as a layered narrative. An initial layer explores how a case, written by a prospective teacher, was interwoven with her past and future life history. A second layer looks at sociocultural and professional tensions that mediated the participants' case experience. A third layer represents how the case experience provided a community that supported critical reflection among the research team members. Implications from the study emphasise that case-based pedagogy can serve as a basis for critical reflection to inform community-based approaches to science teacher education pedagogical and research reform. 相似文献

ABSTRACTSMART Education Technologies (SET) are already in place to provide teachers with different software packages and technologies to facilitate their teaching. However, when it comes to mathematics teaching in Russia, the situation here is different as the articulation of such SET in the Russian context is inadequate. This study redefines mathematics teacher education with smart technologies and identifies IT competencies that are needed to cope with the redefined curriculum. The designed course programme was implemented in the Elabuga Pedagogical Institute, involving 7 teachers from the Institute, 123 students (trainee teachers) and 5 schoolteachers (experts) to keep a professional eye on the learning experience. To evaluate the effectiveness of the curriculum, a survey was carried out among teachers and experts. The survey questionnaire captured the progress made in competence development alongside three modules. The progress that students were making throughout the course was evaluated at the ‘mock teaching’ lesson, where students presented their individually prepared parts of a lesson on a given topic using Information and Communication Technologies (ICT). The way the learning process was organised encouraged students to use various software packages to handle maths-related problems. The research results showed that the SET learning path was flexible and allowed modification of the instructional strategy to better meet the needs of individual learners. 相似文献

Selective mutism (SM) is a rare anxiety disorder that compromises children's daily life during critical periods of early development. Because school is a prime context for the manifestation of the disorder, the aim of this study was to investigate the quality of the student–teacher relationship and its effects on behavior and work, and on social and relational skills. The sample consisted of 75 children—15 were affected by SM, with 60 in the control group—and 15 teachers. The results showed greater difficulty on the teacher's part to establish a relationship based on affective closeness with a child affected by SM, compared to that with unaffected children. Nevertheless, an encouraging picture emerges of the inclusion and integration of the child with SM among peers and therefore in the class group. 相似文献

This study examined evidence of equity for English Learners-one of the three targeted student groups–in the early implementation of California’s Local Control Funding Formula (LCFF) across data sets from seven studies. We used social justice inquiry methods and data integration analytic approaches that included purposeful sampling of districts’ Local Control and Accountability Plans (LCAPs), and data integration analyses of interviews with education leaders to examine how equity was advanced for English Learners. Our findings reveal that the quest for equity for English Learners is elusive and requires multilevel efforts to reverse the national, state, and local histories of unequal treatment, deficit orientations, socio-political dynamics, and legacies of unequal funding that still permeate many schools. Further advances in equity will require greater systemic coherence that sharpens the focus on educational outcomes for English Learners. California’s most recent policy shifts–including the passage of Proposition 58 and the English Learner Roadmap–show promise of systemic coherence and alignment to an assets-based approach for English Learners in the state and nation, as tangible evidence of equity in services and outcomes are still works in progress. 相似文献

There has been strong policy interest in universities becoming more entrepreneurial and engaging in knowledge exchange activities as part of an expanding third mission agenda. However, our understanding of the evolution and diversity of such activities is limited. Using longitudinal data from the Higher Education Business Community Interaction (HEBCI) Survey, this study examines the evolving configuration of universities' knowledge exchange activities and stakeholders by analysing distinctive clusters of English universities. We find an increasingly diverse profile of third mission activities across different types of universities: within old, more established universities, Russell Group universities increasingly focus on research‐oriented activities typically in partnership with large firms and non‐commercial organisations; while another group engages in a broad range of knowledge exchange activities with low specialisation over time. Newer, less research intensive, universities increasingly rely on activities such as consultancy and formation of spin‐offs. A decreased engagement with small and medium enterprises and a lower share of knowledge exchange activities at the regional level are observed across the time studied for all universities. 相似文献

We report an in-depth study of the long-term reproducibility and reliability of droplet dispensing in digital microfluidic devices (DMF). This involved dispensing droplets from a reservoir, measuring the volume of both the droplet and the reservoir droplet and then returning the daughter droplet to the original reservoir. The repetition of this process over the course of several hundred iterations offers, for the first time, a long-term view of droplet dispensing in DMF devices. Results indicate that the ratio between the spacer thickness and the electrode size influences the reliability of droplet dispensing. In addition, when the separation between the plates is large, the volume of the reservoir greatly affects the reproducibility in the volume of the dispensed droplets, creating "reliability regimes." We conclude that droplet dispensing exhibits superior reliability as inter-plate device spacing is decreased, and the daughter droplet volume is most consistent when the reservoir volume matches that of the reservoir electrode. 相似文献
