How the digital divide hinders children’s right to education: Online learning in Brazil

The digital divide in Brazil is both well-known and well documented. Although trends show growth in the general use of the internet, almost 5 million Brazilian children live in homes without internet access. In terms of quality, the situation is aggravated by the fact that there is a predominance in the use of mobile phones for internet access, especially by poor children.

TikTok, Tweens and Influencers: Exploring Children’s Digital Playgrounds

Rarely does a day pass without TikTok mentioned in the media: whether it is a report of the latest viral video, a social media influencer’s shocking behaviour, or the platform itself allegedly failing to protect children’s safety and data, all of which leave many adults worried and puzzled at the appeal of the platform. For children, however, when it comes to TikTok, it is a different story altogether.

About CO:RE

Children and young people go online virtually every day. International data on children and online media is extensive, heterogeneous and partly contradictory.

Our aim is to create a comprehensive pan-European knowledge platform with the participation of international researchers, educators, policy makers and concerned dialogue groups. Providing an overview of the research situation, enabling access to empirical data, distributing policy recommendations and offering resources for education lie at the heart of our work.


Our mission

The aim of the coordination and support project “Children Online: Research and Evidence (CO:RE)” is the conception and implementation of a comprehensive and at the same time dynamic, pan-European knowledge platform on the experiences of children and young people in digital communication spaces and the effects of technological changes on children and young people.

The CO:RE knowledge platform provides a holistic overview of the current research landscapes and enables access to empirical data for re-analysis. Furthermore, it offers a range of resources and materials, such as blog posts, reports, and e-brochures for researchers, educators, and policy-makers alike for more than 30 European countries.

The project is funded within the EU framework of DT-TRANSFORMATIONS-07-2019: “The impact of technological transformations on children and youth” and has a duration of three years.

CO:RE Project Structure

Structure of the Project

The work of the CO:RE consortium is structured in eleven distinct work packages (WPs) over the project duration of three years (2020-2022).

Thereby, the objectives, tasks and deliverables within the WPs are closely interlinked to achieve the CO:RE project goals. WPs 1 and 10 support and coordinate the overall project framework.

WP 1: Management

WP 1 coordinates the project and the consortium and ensures that all project objectives are achieved and that the CO:RE platform is implemented.

Further, it coordinates the communication and dissemination activities that both promote the CO:RE platform to researchers and other stakeholders, i.e. educators, policymakers and industry partners. Ultimately, the goal is to anchor the CO:RE platform as the central hub for children’s and youth’s ICT research, evidence, and data for all concerned actors.

CO:RE Evidence Base

WP 2: Evidence Base

WP 2 collects existing research evidence about how children and young people behave and interact online, as well as the risks they may encounter while online. Thereby, particular attention is devoted to the vulnerabilities of children and young people in the digital environment, published in all participating and affiliate countries since 2010 (2010-2013: EU Kids Online; as of 2014: CO:RE).

In doing so, WP 2 provides a structured database identifying and describing research evidence to make them available and researchable to European researchers and stakeholders.

Additionally, the CO:RE Evidence Base cross-references to the CO:RE Data Archive for data sets applicable for re-analysis.

WP 2 Lead: Università Cattolica del Sacro Cuore

WP 3: Data Archive

WP 3 identifies and collects existing data sets that can be used for re-analysis.

In this process, it builds a systematic and comprehensive data archive on the impact of digital technologies on children and youth in Europe since 2010 (2010-2013: EU Kids Online; as of 2014: CO:RE). Furthermore, the CO:RE Data Archive cross-references to the CO:RE Evidence Base and links together published evidence and data sets.

WP 4: Key Topics

WP 4 identifies and monitors the most relevant topics in the broad and multidisciplinary research area of children and youth in digital media environments.

In doing so, WP 4 interlinks vital issues with existing theoretical insights and empirical evidence and publishes a series of short reports and blog postings to inform stakeholders and to instruct policy recommendations in national as well as international contexts.

WP 4 Lead: University of Tartu

WP 5: Theories

WP 5 provides a series of cross-fertilising mechanisms and activities to coordinate and support the theoretical plane of research on the impact of technological transformations on children and youth.

By identifying disciplinary perspectives, interrogating theoretical and conceptual assumptions and bringing together contrasting academic positions, WP 5 explores new theories, ideas and disciplinary viewpoints to refresh established lines of inquiry and thus aiding innovation and advancement in the field.

In doing so, WP 5 develops a series of constructive and practical tools to support theoretical development, such as multidisciplinary webinars, online fora and workshops.

CO:RE Methods

WP 6: Methods

WP 6 provides a digital portfolio of resources on qualitative, quantitative and mixed research methods to researchers, universities and youth education interested in the field.

By catering to various disciplines concerned with children and youth online, WP 6 enhances the understanding of how to research the long-term impact of digital media on children and youth, including the standards, practices and particularities of co-research together with children. In doing so, WP 6 provides workshops, a summer school, as well as an online handbook on mixed methods and validation of research treating children and youth as media users as well as empirical experts.

WP 6 Leader: Tampere University

WP 7: Ethical Issues

WP 7 delivers a digital portfolio of resources on research ethics to researchers, informants (including children) and others, enhancing the understanding of how to conduct research with children in an ethical manner and in accordance with relevant law.

Thereby, the principles of good scientific practice, including reliability, honesty, respect and accountability, as described in the European Codes of Conduct for Research Integrity, are critical aspects.

In doing so, WP 7 provides an online one-stop-shop for researchers, explaining relevant laws, presenting standards of informed consent in different European countries, and offering checklists, templates and guidelines to students and researchers. Further, WP 7 gives workshops and training seminars, and publishes a handbook directed at children on participating in research and their roles as informants, which will be available in different European languages.

CO:RE Policies

WP 8: Policies

WP 8 facilitates and promotes the uptake of state of the art scientific research by policymakers, while fostering feedback loops that allow policymakers to bring attention to under-researched, yet necessary aspects for policy making.

In doing so, WP 8 publishes a series of Policy Briefs in close collaboration with other WPs publications of reports, e-brochures, and blog postings.

Furthermore, WP 8 provides an online directory of European policymakers relevant to children, youth and digital media, offers an annual policy seminar, arrange a youth policy forum ensuring seldom heard voices’ appropriate representation and inclusion in policymaking, and hosts a joint research-industry forum, promoting exchange on topics of mutual relevance between scholars and industry policy specialists.

WP 8 Leader: TU Dublin

WP 9: Education

WP 9 bridges CO:RE to the educational sector and establishes cooperations, which aim at increasing recognition of existing evidence on the impact of technological transformations on children and youth with educational stakeholders in Europe and beyond.

Further, WP 9 engages with the educational stakeholder group in teachers training, informing curricular developments, project work as well as peer-to-peer training and parents’ information sessions around online safety.

WP 9 establishes, beyond that, a robust feedback look from the educational community that helps initiating future research and informing the work of the CO:RE project.
