Explanation:

In order to support transformational learning experiences by strengthening digital citizenship an infrastructure must have:

Ubiqutous connectivity: this means that high-speed Internet should be available for every student everywhere and at any time. Powerful learning devices: Students need to be able to access devices that connect them to their teachers and other learners, as well as all the resources available on the internet. This enhances the way they co-create new knowledge with others by enhancing and facilitating communication and collaboration. For this purpose it is important that educators collaborate with one another as well as with students, looking for ways to connect students with their learning in a contextual and critical manner.High-quality digital learning content: This means that the content available for students should be relevant for the context they live in, so they can engage with knowledge in a meaningful way.  This relates with how learning environments support a meaningful connection with learning, by going beyond the classroom and aiming for students to apply what they learn. Responsible Use Policies: Guidelines available for students so they can access the infrastructure safely.
