The issue that this article introduces grew out of an event, the UNESCO Mobile Learning Week, but also out of a wider and growing movement of people and organisations exploiting mobile technologies, as they pursue varied educational missions. The UNESCO Mobile Learning Week represented by contributions here was a focus for contributions from across the field. This article provides a wider discussion of these contributions, first by looking at the achievements of UNESCO and then by considering these achievements more critically. In particular, it highlights several sets of inherent challenges facing UNESCO and other organisations engaging in mobile learning: those around evidence, evaluation, and sustainability; the problematic tension between large-scale interventions, based on scale and content delivered by national governments, and the language and culture of marginal or indigenous people; the absence of appropriate ethics procedures to manage educational interventions delivered by a powerful and ubiquitous technology; and the absence of learners in the forums that address all these various issues. 相似文献

A random sample of language arts, social studies, and science middle school teachers from the United States were surveyed about their preparation to teach writing, beliefs about responsibilities for teaching writing, use of evidence-based writing practices, assessment of writing, use of technology, and adaptations for struggling writers. The findings from this survey raised concerns about the quality of middle school writing instruction. Many teachers believed their preservice and inservice preparation to teach writing was inadequate. Middle school students spend little time writing or being taught how to write. While most teachers used a variety of evidenced-based writing practices and made adaptations for struggling writers, such methods were applied infrequently. Most teachers did not appear to use assessment data to shape how they taught writing, and computers played a relatively minor role in middle school writing instruction. Even though teachers generally agreed that writing was a collective responsibility, language arts teachers placed a greater emphasis on writing instruction than social studies and science teachers. 相似文献

Does spelling instruction make students better spellers,readers, and writers? A meta-analytic review
Despite the importance of spelling for both writing and reading, there is considerable disagreement regarding how spelling skills are best acquired. During this and virtually all of the last century, some scholars have argued that spelling should not be directly or formally taught as such instruction is not effective or efficient. We conducted a comprehensive meta-analysis of experimental and quasi-experimental studies to address these claims. The corpus of 53 studies in this review included 6,037 students in kindergarten through 12th grade and yielded 58 effect sizes (ESs) that were used to answer eight research questions concerning the impact of formally teaching spelling on spelling, phonological awareness, reading, and writing performance. An average weighted ES was calculated for each question and the quality of included studies was systematically evaluated. Results provided strong and consistent support for teaching spelling, as it improved spelling performance when compared to no/unrelated instruction (ES = 0.54) or informal/incidental approaches to improving spelling performance (ES = 0.43). Increasing the amount of formal spelling instruction also proved beneficial (ES = 0.70). Gains in spelling were maintained over time (ES = 0.53) and generalized to spelling when writing (ES = 0.94). Improvements in phonological awareness (ES = 0.51) and reading skills (ES = 0.44) were also found. The positive outcomes associated with formal spelling instruction were generally consistent, regardless of students’ grade level or literacy skills. 相似文献

This study explores the relationship between several structural level variables and repeat viewing of prime‐time public television programming. A strong positive correlation was found between audience ratings and repeat viewing. Analyses of variance were performed on repeat viewing using program scheduling, presence/absence of continuing dramatic story line, and household cable status, and significant effects for repeat viewing occurred for all. A regression model utilizing these variables accounted for a moderate degree of variance in repeat viewing. 相似文献

This article examines the promotion and adoption of action research as an instrument of institutional change by academic staff in a Brazilian rural university. The results of the research are presented showing the mobilisation of a group of volunteers, the implementation of their action research projects and the sustainability of the process. Particular attention is drawn to the significance of an insider change agent/facilitator as the initiator of the action research process and how his role became superfluous as the networks evolved into true communities of practice. On reflection the original composite daisy model of Melrose and Reid has been discarded in favour of a simpler buttercup‐type flower model of analysis to describe the process. 相似文献

Abstract This article explores the experience of a group of young people who experienced difficulty attending school. Young people's reasons for not attending school and the support provided for them by their teachers are examined. Finally, an analysis based on a shift in identity from school refuser to effective learner is offered as an explanation for the students' success in coping with school. The authors draw on Paul Klee's metaphor of art as a development that can go forwards, backward, up and down as similar to the processes of working with such young people. They argue that to expect linear progress is both unrealistic and sets unfair expectations on students and their teachers. 相似文献
