Read full description

With iTeo stories in any target language can be produced while relying on the native language for discussing and negotiating the contents of the story as well as the language forms needed. Within schools iTeo can perform a differentiated lot of didactical approaches to oral language learning. iTeo outgrows the β€˜simple’ tool metaphor so often referred to when it comes to describe the implementation and the role of technological devices in the learning and educational processes. iTeo offers opportunities of language production and of sustained language learning in the distributed network and association of human and non-human.

About

ProtAct17

Read full description

The app aims to provide children and adolescents with a playful approach to the complex topic of sustainability and the 17 sustainability goals of the United Nations. ProtAct17 imparts knowledge in an age-appropriate and interactive way, arouses curiosity and the spirit of research through virtual and real experiments, addresses current and future challenges for the environment, economy and society and shows their own – albeit small – possibilities for action. Inspiring and empowering students to protect the environment (Protect) and to take action in line with the 17 sustainability goals of the United Nations (Act) – this is the idea behind the app. Using the scan mode, children can bring the app's poster to life and explore the topics step by step.
