“Relocating the Personal” to engender critically reflective practice in pre-service literacy teachers

This case study mapped candidates' responses to a pre-service literacy course designed to relocate teacher candidates' literacy histories and beliefs from a personal to political frame with the intent of promoting critical reflection and complex understandings of literacy, teaching, and learning. As part of a broader qualitative case study including 71 participants over 8 months, this paper focuses on data gathered from 7 candidates. Through a modified constant comparative method, the analysis confirmed the effectiveness of certain conditions created in the course while pointing to a need for further attention to issues of power and the unconscious in learning to teach literacy.     

Diversity study circles in teacher education practice: An experiential learning project

This paper addresses the dilemma of trying to prepare primarily white preservice teachers for educational arenas in which they will interface with students of colour and many who are socially disadvantaged. This paper describes how diversity study circles can be integrated as integral to education that is multicultural in the development of preservice teachers’ critical self-reflection as a bridge to developing a critical lens for classroom practice and a democratic society.     

A contextual critique of critical literacy: Freirean ‘generative themes’ and their impact on pedagogic practice

Public education in post-industrial societies has been restructured based on a human capital model that prioritizes the economic value of citizens for the benefit of globally competitive national economies. In a policy-as-numbers climate [Lingard, B. (2011). Policy as numbers: Ac/counting for educational research. The Australian Educational Researcher, 38(4), 355–382], school administrators and teachers struggle to ‘produce results’ and ‘close gaps’ within accountability systems built on standardized measures of learning. What possibilities exist for critical literacy as viable classroom pedagogy in such an environment? This article offers a contextual–empirical analysis of efforts to implement critical literacy in mainstream secondary classes in Singapore. Drawing on Freire’s notion of generative themes, it identifies key political-policy constraints, showing how they impacted the pedagogical enactment of critical literacy tenets and pinpointing a focal direction for critical literacy in Singapore’s English education. More generally, the article argues that critical literacy, more than ever, must be a localized practice responding to exigencies emerging at the global–local nexus.     

数字素养概念与内涵辨析——兼与信息素养、媒介素养、技术素养的比较

数字素养是计算机、教育学等学科研究热点。但随着技术素养、信息素养等新概念被提出,出现了混淆或误解的情况。因此,为避免今后研究中出现概念模糊、重点要素遗漏等问题,采用文献研究法,从概念时代背景、内涵等多个方面进行探讨,并以对比的形式理清相关概念区别和联系。研究发现,不同的概念均是依据时代对不同知识技能需求而产生的,且各有侧重,概念之间既有补充也有包含关系,数字素养作为最近提出的概念,具备更深层和更广泛的特点。     

Latinx* popular culture imaginaries: examining Puerto Rican children’s social discourses in interpreting telenovelas

Abstract

In this paper, we present a collaboration project within one urban Puerto Rican classroom, focused on constructing a critical literacy inquiry curriculum grounded in the students’ out-of-school literacy practices in their communities, including their experiences with media and popular culture. We focused on a critical literacy and media inquiry unit centered on the students’ self-selected subject of the telenovela. Here, we examine one student’s work to highlight two overarching findings: (1) the visibility of the students’ complex understanding of the media landscapes in telenovelas, particularly the construction of dominant social discourses across telenovela worlds, and (2) the ways that bringing children’s mediatized cultural imaginaries in their creative work supports an approach to literacy in classrooms, where explorations of discourses of power emerge from the students’ knowledge. In order to articulate how children actively examine and construct discourses across multiple social worlds, we examine these findings using the Four Resource Model, and elements of discourse analysis, as theoretical and analytical frameworks, focusing on the construction of identities, worlds and meanings in relation to the social discourses of telenovelas.     

Reading the Web—Students' Perceptions about the Internet

This study explores the perceptions of Finnish 15‐year‐olds on the advantages and disadvantages of the Internet. The data, students' written responses (N = 3112), were gathered in the context of the OECD Programme for International Student Assessment (PISA) in the spring of 2000 as a national option. The data were analysed by close reading and using the Atlas.ti application for coding. Students regard easy access to a variety of current information as the most important advantage of the Internet. Finding new friends and chatting with old ones was also emphasised, as well as the downloading capacities of the Internet. Although problems of finding reliable and truthful information were recognised, students' main concerns were related to issues such as violations towards computers and people, and getting addicted or marginalised.

高中生技术素养的维度与水平--基于北京的调查

技术素养已经成为公民必备的基本素养,与科学素养并列,关系到国家的综合实力和科技竞争力。本研究整合国外成果将技术素养分成知识、能力、批判性思维和决策、态度四个维度,横向领域结构包括技术和社会、设计与系统、信息与通信技术,具体分为4个一级指标,12个二级指标和36个三级指标。对北京1520名高中生进行了实证调查,从技术素养的知识、能力、批判性思维和决策、态度这4个一级指标进行了基本水平的统计,具体涉及三级指标的描述性分析、典型指标的频率分析等。调查研究结果表明：在知识维度,学生对于核心产品、形式产品、附加产品、核心概念、故障诊断、工具、材料的知识掌握很好,这7项的得分都达到高分的类别,但是学生在设计系统和其他资源的知识掌握欠佳。整体来看,高中生技术素养整体水平薄弱,尤其在技术素养的核心维度表现不佳,对于学生技术素养的培养不仅需要在政策层面得以重视,也应该在实际教学中显化。     

Digital play as a means to develop children’s literacy and power in the Swedish preschool

Abstract

This paper presents different angles on the subject of digital play as a means to develop children’s literacy and power, using an online ethnographical study of Swedish preschool teachers’ discussions in informal online forums. Question posts (n = 239) were analysed using the Technological Pedagogical Knowledge framework and the Caring, Nurturing and Teaching framework, with the aim of understanding how teachers intended to support children’s literacy development with tablets. Literacy development can be understood as a social practice that needs to develop along with changes in society’s demands on citizens. The results presented indicate that school subject oriented skills are predominantly present in the mind-set of these preschool teachers. When digital play is increasingly used for pedagogical purposes in preschools, that also means that preschools have expanded their opportunities to work with children’s literacy development. For preschool teachers, it is important to discuss how literacy development can be supported in a contemporary media landscape.     

Dimensions of digital literacy based on five models of development / Dimensiones de la alfabetización digital a partir de cinco modelos de desarrollo

Abstract

Digital literacy has been an emerging and increasing priority in many governments’ educational and assessment policies since the first decade of the twenty-first century because it is a priority in citizenship training. The difficulty with understanding and developing it comes from its changing, transversal and flexible nature; for this reason, the fundamental objective of this research is to offer an exhaustive study of the concept by analysing the main models of digital literacy in the international context in order to offer a holistic model that incorporates the contributions from all of these initiatives. The theoretical study presented herein provides an objective, rigorous perspective on the main models of development of digital literacy: the DIGCOMP Project (European Commission), the Krumsvik model (Norway), the TPACK model (USA), the JISC model (UK), the ISTE Standards (USA) and the P21 model (USA). The conclusion offers an innovative proposal of four dimensions that should define digital literacy today, taking into account the five initiatives studied, which could be very worthwhile for researchers, educators and policymakers.

Splicing the Divide: A Review of Research on the Evolving Digital Divide Among K–12 Students

The digital divide has narrowed with regard to one definition of access to technology—the binary view of the “haves” and “have-nots.” However, use of technology at home and in school is not equitable for all students. According to recent literature, a broader and more nuanced definition of the technological divide is necessary in order to express the ways technology is used or not used. The purpose of this research review is to examine the defining characteristics of technology use by K–12 students, highlighting the complexities of the evolving digital divide. This review integrates findings from empirical studies, theoretical articles, research reviews, and government surveys in the United States in order to present a renewed look at an evolving digital divide, explore the underlying causes of the unequal student use of technology, suggest directions for future research, and provide current implications for practice.
