This article addresses how methodological approaches relying on video can be included in literacy research to capture changing literacies. In addition to arguing why literacy is best studied in context, we provide empirical examples of how small, head‐mounted video cameras have been used in two different research projects that share a common aim: understanding the complex ways in which literacy is a part of school practices. The complexity of literacy practices taking place in classrooms, where students draw on a number of texts for a variety of purposes and different literacy discourses co‐exist in the same setting, poses a serious challenge for those who wish to study literacy in educational settings. The methodology presented in this article is our attempt to meet this challenge. Our approach relies on using video equipment in innovative ways to capture multiple perspectives, involving research participants in the data collection process and the early stages of analysis, and analysing video data with digital coding software. These methods are combined to obtain a more systematic and detailed insight into the contexts in which literacy takes place. 相似文献

Touchscreens are being integrated into classrooms to support collaborative learning, yet little empirical evidence has been presented regarding how children collaborate using touchscreens in classrooms. In particular, minimal research has been directed towards how teachers can design for and guide children’s touchscreen-based collaboration. Concurrently, the Programme for International Student Assessment and other international organisations have highlighted collaboration and ICT skills as crucial competencies for mastery in the twenty-first century. Accordingly, this article presents three narrative cases from a touchscreen project in Denmark, where 41 second-grade children and three teachers from two classrooms participated. The cases are based on ethnographic field data and 150 hours of video footage of natural occurring interaction in classroom settings. The ethnographic field data and video footage are examined using a collaboration model and embodied interaction analysis. Each case presents features of the subtle processes of children’s collaboration around touchscreens and teachers’ role in designing and guiding such collaboration. Thus, this article illustrates teachers’ and children’s situated processes of integrating touchscreens for collaborative activities in their classrooms. 相似文献

Audio- and video-recordings are increasingly popular data sources in contemporary qualitative research, making discussions about methodological implications of such recordings timelier than ever. This article goes beyond discussing practical issues and issues of ‘camera effect’ and reactivity to identify three major challenges of using video to ‘capture’ social practices: (1) getting close enough to details without losing context, (2) encountering the most severe consequence of ‘death by data’ – namely magnifying events that may not be significant to participants, and finally, (3) representing data so that an audience can actually assess whether inferences drawn from the data are plausible. These important issues directly impact the credibility of qualitative research relying on video. The article combines existing literature with contemporary examples from educational research to critically discuss these three key challenges and some possible ways of addressing them. 相似文献

This study examined how YouTube creates a unique, nonformal cyberspace for Black females to vlog about natural hair. Specifically, we utilized qualitative video data analysis techniques to understand how using YouTube as a facilitation tool has the ability to collectively capture and maintain an audience of more than a million adult learners. After analyzing 30 videos, 4 themes emerged reflective of how using the technology of video assists these nonformal adult educators with regard to: (a) Demystifying Black Natural Hair Myths, (b) Digital Storytelling as an Educational Tool, (c) The Use of Humor, Honesty, and Humility While Facilitating Adults, and (d) The Natural Hair Thing Extends Beyond Cultural Differences. Lastly, we offer implications for future research with regard to the availability and credibility of YouTube as a data source and alternative qualitative video data analysis techniques. 相似文献

This paper discusses a year‐long technology integration project during which teachers and researchers joined forces to explore children's collaborative activities through the use of touch screens. In the research project discussed in this paper, 16 touch screens were integrated into teaching and learning activities in two separate classrooms; the learning and collaborative processes were captured by using a video, collecting over 150 hours of footage. By using digital research technologies and a longitudinal design, the authors of the research project studied how teachers and children gradually integrated touch screens into their teaching and learning. This paper examines the methodological usefulness of video‐based multimodal analysis. Through reflection on the research project, we discuss how, by using video‐based multimodal analysis, researchers and teachers can study children's touch‐screen supported collaboration and how researchers and teachers can learn together. 相似文献

This paper explores the use of the video sharing site, YouTube, as a platform for enhancing moral and psychosocial development through increased awareness of moral values and models of moral behavior. The research involved a qualitative design whereby video snippets illustrating moral issues were identified from YouTube. These video snippets were analyzed in terms of their viewership, the moral dilemma and the levels of moral judgment that they presented. The comments made by viewers in response to the video contents were then captured and their contents analyzed for evidence of moral reasoning and ego (psychosocial) development. The findings showed that the video sharing websites such as YouTube offered opportunities for moral issues to be featured, shared and discussed at a global level, as well as moral judgments and ego development to be made evident through viewers' comments. From an educational viewpoint, it also paves the way for the use of appropriate video footage for promoting moral values and moral development. 相似文献

Approaches to rectifying the inequities Black female students encounter in U.S. educational institutions are rarely discussed in the body of research in which these individuals are the foci. In this critical race feminist auto-ethnography, the author used qualitative data from a two-year study of a girls' empowerment program that she established at an urban public high school. Through an analysis of Black feminist curricula, in-class video footage, student artifacts, and interviews with former participants, the author argues that Black feminist pedagogy may promote the development of positive social and academic identities among African American female youth. Concrete, research-based guidelines for developing culturally responsive pedagogical interventions are discussed. 相似文献

As applications of multilevel modelling in educational research increase, researchers realize that multilevel data collected in many educational settings are often not purely nested. The most common multilevel non-nested data structure is one that involves student mobility in longitudinal studies. This article provides a methodological review of three statistical methods for handling student mobility in longitudinal studies: a multilevel approach, a cross-classified approach, and a cross-classified multiple membership approach. The strengths and weaknesses of each approach and the essential differences between the three approaches are discussed. The Early Childhood Longitudinal Study Kindergarten Cohort data are analysed to demonstrate the differences in parameter estimates and statistical inference between the three approaches. Potential applications of the three approaches in educational research and beyond and directions for further methodological investigations are discussed. 相似文献

ABSTRACT: This paper considers the use of secondary data analysis in educational research. It addresses some of the promises and potential pitfalls that influence its use and explores a possible role for the secondary analysis of numeric data in the 'new' political arithmetic tradition of social research. Secondary data analysis is a relatively under-used technique in Education and in the social sciences more widely, and it is an approach that is not without its critics. Here we consider two main objections to the use of secondary data: that it is full of errors and that because of the socially constructed nature of social data, simply reducing it to a numeric form cannot fully encapsulate its complexity. However, secondary data also offers numerous methodological, theoretical and pedagogical benefits. Indeed by treating secondary data analysis with appropriate scepticism and respect for its limitations, by demanding that tacit assumptions about the unreliability of secondary data are applied equally to other research methods, and crucially by combining secondary data analysis with small-scale in-depth work, this paper argues for a return to prominence of secondary data analysis in its own right as well as becoming a central component of the new political arithmetic tradition of social research. 相似文献

教育理论的特质及其研究使命 总被引：5，自引：0，他引：5
新世纪中国的教育研究需要承担一种理论的使命,这就要求梳理教育理论的知识类型和确立其理论形态。这种理论形态,不是单一理论,而是一个理论连续统, 包括由抽象命题构成的具有反思功能的一般理论,呈现方法论要求的中层理论,表现具体经验的微观理论。它们之间不是孤立分离的,而是相互联系,彼此互动的。探讨教育理论的问题结构及其独特意义,可以认为教育理论的进步也意味着对教育条件的认识所取得的进步。 相似文献

Hispanics/Latinos are the fastest growing minority group in the US, and represent a diverse variety of ethnic groups with unique heritages. Yet educational and social research often analyzes this group in aggregate. This research, employing 1980 high school senior longitudinal data from the High School and Beyond project, demonstrates substantial differences in post-secondary educational attainment between some Hispanic/Latino groups. Net of a number of individual, socio-economic, family and high school background variables, logit analysis shows that Mexican Americans are significantly below others in post-secondary educational attainment after high school. The results are discussed in regard to future research adopting analysis of individual Hispanic/Latino groups rather than employing the aggregate measure which can substantially misrepresent the relationship between component Latino/a groups and educational attainment.We are indebted to Robert Kaufman for consultation on methodological and statistical approaches; and to Michael Hughes, James Michaels, and Ellen Plummer for helpful suggestions for revision on earlier versions of this paper. This paper is based in part on a Master’s thesis by the first-named author. 相似文献
