In this systematic review of literature that spans 1975–2015, integrated reading and writing interventions for students with learning disabilities (LD) or students with academic difficulties were evaluated to understand the extant research, identify encouraging practices, and guide future research. Ten studies met inclusion criteria and each study was evaluated according to the relevant What Works Clearinghouse (WWC) design standards. Eight of the 10 investigations were conducted with students in grades 4–8. While only 4 of the 10 studies met WWC design with or without reservations, results from these studies are encouraging. Study findings suggest several areas for immediate future research relating to methodological and treatment variables and considerations for classroom instruction in order to respond to advanced expectations for the successful integration of reading and writing across subjects. In addition to employing stronger experimental designs and additional replications of encouraging studies, future research should explore the utility of integrated reading and writing interventions with secondary students with who have academic difficulties.  相似文献

This study investigated five different aspects (mental image, physical image, source of the image, 'scientists around us', and 'my favourite scientist') of Korean students' images of the scientists. The data, quantitative and qualitative, from the responses of a total of 1137 students from three different groups (age 11, 13and 15) were analysed to calculate the relative frequencies of some identified patterns of responses and to make comparisons between different genders and different age groups. Korean students generally showed, but to a slightly lesser extent, some stereotypical images of the scientist which were revealed in previous studies. These were influenced more by affective and ethical personal characteristics of the scientist than by their cognitive and gifted abilities. Some noticeable age-related and gender-related differences were also found and discussed.  相似文献

To alleviate teachers’ reluctance toward practical work, there has been much discussion on teachers’ pedagogical content knowledge, teaching materials, and failsafe strategies for practical work. Despite these efforts, practical work is still regarded as a challenging task for many elementary science teachers. To understand the complexity of teachers’ conflicts in practical work, this study examines teachers’ ideas about teaching and learning that influence teachers’ decision‐making and action on teaching practical work. More important than knowing technical–rational aspects of practical work is to understand the internal contradictions that teachers have to resolve within themselves regarding their capabilities and beliefs about science teaching and practical work. Using stories and experiences of 38 third‐year university students in a science method course in Korea, we seek to understand the conflicts and negotiations that they experience as they make decisions regarding practical work throughout their course. Reflective writings and group discussions on their lived experiences and concerns were used to probe participants’ ideas on teaching using practical work. From written and verbal data, themes were saturated in terms of the aspects which could (dis)encourage their practice. Results suggest that there are multifactorial challenges in pre‐service teachers’ understandings and concerns in practical work. Besides time, materials, and curriculum, pedagogical assumptions and values also compositely challenge the minds of teachers. As the pre‐service elementary teachers negotiated within themselves the importance of science in classroom and social levels, the question is raised about their identities as pre‐service elementary teachers to appreciate the balance between science teaching and practical work.  相似文献

This article maintains that all research involves crossing (i.e., researching across difference) and then explores how scholars have approached issues of cross-group feminist research. The article is divided into three major sections. The first section explores issues of women?s diversity and their meaning for cross-group feminist research. The second investigates concerns raised with regard to contradictions inherent in this type of research. The third section reviews and discusses a number of strategies feminist and other scholars of qualitative research have used to address problematic issues and contradictions involved in cross-group research.  相似文献

In recent years, many U.S. states have introduced growth models as part of their educational accountability systems. Although the validity of growth‐based accountability models has been evaluated for the general population, the impact of those models for English language learner (ELL) students, a growing segment of the student population, has not received sufficient attention. We evaluated three commonly used growth models: value tables or transition matrices, projection models, and student growth percentiles (SGP). The value table model identified more ELL students as on track to proficiency, but with lower accuracy for ELL students. The projection and SGP models were more accurate overall, but classified the fewest ELL students as on track and were less likely to identify ELL students who would later be proficient. We found that each model had significant trade‐offs in terms of the decisions made for ELL students. These findings should be replicated in additional state contexts and considered in the development of future growth‐based accountability policies.  相似文献

The world culture framework posits a convergence in the organisation of education across the world. On the other hand, scholars observing teaching practices inside classrooms find significant variation among nations and regions of the world. This study examined the global change patterns of classroom practices at the between- and within-country levels, drawing on teacher reports from the Trends in Mathematics and Science Study. Results indicate clear between-country convergence toward more student-centred and conceptual instruction. But a nation’s degree of conformity or resistance to this model was contingent upon other nation-specific factors, including centralised curriculum control or world regional location.  相似文献

This study explored the factors affecting repeat theatrical viewing of movies. Integrating content, social influence, and access/competition variables, the analysis reveals that the drivers of theatrical repeat viewing are different from those for box office performance. For example, the effects of genre, transmedia content, and audience review were significant only for the latter and factors such as movie length, critics’ review, and level of news coverage actually played a negative role in the repeat consumption.  相似文献

This study employed the uses and gratification approach to investigate how journalists perceive relational satisfaction with the public on Twitter, specifically the associations between journalists’ motivations to use Twitter, their Twitter use, and their relational satisfaction with the public. Through a survey of South Korean journalists, this study revealed that journalists’ motivations for Twitter use are positively related to their job-related activities on Twitter (e.g., posting/sharing their news and interacting with audience), which consequently influences perceived relational satisfaction with the public. The findings provide new insight into an increasingly important part of the public’s engagement and news/information flows in the digital media environment. This study expands upon the literature by analyzing how journalists’ motivations for using Twitter and their job-related activities on Twitter are associated with relational satisfaction with the public.  相似文献

This study investigated relationships between social media motivation, relative preferences for social media type, and network heterogeneity, using a U.S. national survey. By classifying social media into the symmetrical and the asymmetrical, we showed that relationship motivation was more likely to be associated with a preference for the symmetrical type, whereas information motivation with a preference for the asymmetrical. Network heterogeneity was positively predicted by relationship motivation but not by information motivation. Finally, a relative preference for the symmetrical type was found to mediate the association between relationship motivation and network heterogeneity.  相似文献
