New concepts of play and the problem of technology,digital media and popular-culture integration with play-based learning in early childhood education

Technology, digital media and popular culture form an important aspect of young children’s life-worlds in contemporary post-industrial societies. A problem for early childhood educators is how to most effectively integrate these aspects of children’s life-worlds into the provision of play-based learning. Traditionally, research has considered barriers to teacher uptake of technologies in the early years, or teacher beliefs and attitudes about using technologies with young children. An alternative perspective focuses on children’s play as the foundation for early childhood curriculum provision and argues that what is needed instead are ‘new’ concepts of play more appropriate for explaining children’s contemporary play experiences in post-industrial societies. This article examines the influence of a new concept of play called ‘web-mapping’ on teachers’ curriculum practices in early childhood education, and finds that, according to Vygotsky’s ideas about explicit and implicit mediation, new concepts of play are likely to provide a fruitful avenue for addressing the ‘problem’ of technology, digital media and popular-culture integration in early childhood education.     

“You need a phone and camera in your bag before you go out!”: Children’s play with imaginative technologies

Early childhood settings value play as the way young children learn and educators encourage children’s re-enactment of cultural practices in the imaginative play spaces provided. From a cultural-historical perspective, children expect these imaginative play spaces to contain objects from their social contexts, but what happens when technologies are not provided? The aim of this study was to explore children’s imaginative play involving working and imaginative technologies within two kindergartens (the year before formal schooling). Imaginative play spaces are designed to replicate social situations relevant to the cultural context in which they occur and as technologies increase in society, their proliferation is reflected within early childhood settings. Understanding the role that imaginative technologies can play in children’s digital literacy learning is important for the early childhood field. Also, these devices are often absent from literature and overlooked in conversations about children’s digital participation. The findings show how the children engaged with the imaginative technologies and raises questions around the influence of these technologies on children’s imaginative play and their technological understandings. The findings have implications for educators’ understandings of children’s play with technologies and the objects they provide in an era where children’s lives are increasingly immersed in technology.     

Computing for all?: Examining critical biases in computational tools for learning

Given the increased need for broadening participation in computing, there must be a focus not just on providing culturally relevant content but also on building accessible and inclusive computational tools. Most efforts to design culturally responsive computational tools redesign surface features, often through making nominal changes to add cultural meaning, yet the deeper structural design remains largely intact. We take a critical perspective towards novice programming environments to elucidate how the underlying structure privileges particular epistemologies and cultures. In this paper, we examine how the cultural practice of storytelling is supported and/or inhibited within novice programming tools. We draw upon the experiences of 38 Native American youth, who worked in teams to create place-based, interactive stories and games for their community. Findings offer insights to the embedded cultural biases that exist in the structures of computational tools. We discuss insights for how to address cultural biases and promote deeper integration of cultural practices in future designs of culturally responsive computational tools.

Practitioner Notes

What is already known about this topic?

• Culturally responsive computing connects computing content heritage and vernacular cultural practices.
• “Black boxing,” or lack of transparency in how it works, in computational tools makes it difficult for novices to enter computing cultures.
• Design tools are embedded with particular ways of being, knowing, valuing and doing.

What this paper adds?

• Thirty-eight novice learners’ computational designs were shaped by the ways in which a computational tool privileged particular knowledge systems.
• Storytelling, as a critical cultural practice, especially in Indigenous cultures, is heavily constrained by the design structure of computational tools.
• Computational tools are cultural artifacts with deeply embedded epistemological, ontological and axiological biases, which directly frame what learners can do with these tools.

Implications for practice

• Collaborative, community-based design processes could mitigate the cultural biases that persist in computational tools.
• Transparency in computation tools in critical to broadening participation in computing cultures.
• Culturally responsive design of computational tools at the structural level is required to build inclusive computing cultures.

Information and communication technologies: transforming views of literacies in early childhood settings

This paper reports on an early childhood technology project that has been conducted in Australia since 2000. The background to the project is that IBM extended their international KidSmart Early Learning program to the Asia‐Pacific region. A partnership with the Australian National Schools Network was formed to implement the program in Australia. This organisation took responsibility for identification of early childhood centres (preschool and day care) serving low socio‐economic status communities across Australia (approximately 100 centres per year), the design and facilitation of professional development for teachers and research and evaluation in conjunction with the program. Whilst this was a national project, this paper deals only with the research conducted in Western Australia with the first round of centres involved in the project. The paper highlights themes emerging from teacher action research based in early childhood centres. The pedagogical considerations, challenges and dilemmas emerging from teachers' use of ICT in early childhood settings are also discussed.

University professor approaches to case studies: virtual field trips

Representatives from more than 20 institutions making up a research and teaching network met to discuss and investigate a web application designed to promote knowledge sharing and understanding. The web application, called Fieldtrip, enables students, professors and researchers to virtually share their experiences and findings from real field trips. This study investigates how professors from the network conceived Fieldtrip and their approach to designing and teaching student learning experiences using it. Results show that the professors had divergent understandings of the potential of the web application, and that qualitatively better ways of conceiving Fieldtrip were related to more robust approaches to design for learning and teaching. The implications of this study as an exploration into professor experiences of web applications are important if universities wish to make the best use of technologies in learning for their students and professors.

Technological trends in Swedish medical libraries

Medical libraries in Sweden are digitised to a large extent, technically advanced and developing rapidly. This paper investigates technological trends among Swedish medical libraries in the near and distant future and their application within different areas of library activities. The authors also present a roadmap to increase technological developments within medical libraries in Sweden. Current technological trends include digital collaboration tools, mobile technologies and visualisation. Artificial intelligence, big data and smart technologies are upcoming trends. Technologies are applied within all areas of library activities, but preconditions for academic and hospital libraries differ. To remain a relevant provider of information services, libraries must be able to monitor, test and adopt new technologies.
