What media are available? How do I use books, newspapers, and the internet? What does an author do? And how does a journalist work? Issue 19 of the series "Learning on the Net" allows for engagement with the topic of "media" using the internet. Students have the opportunity to collaboratively and action-orientedly discover solutions to problems, as these can be found in various forms online; they just need to be located. "Learning on the Net" takes on this task for you. Each issue includes 20 worksheets as copy templates, which can be independently solved by students through research on designated websites. The interdisciplinary approach in subjects such as social studies, German, and mathematics for elementary school has been taken into account. However, the issues can also be used in secondary education.
