Computer basics - the interactive online book

Computer basics for beginners

Computer basics - the online book!

In 2012, the book "ITG informationstechnische Grundbildung - Computer Basiswissen für die Sekundarstufe 1" was published. In the meantime, a lot has changed and many things have developed further. A book in print form is no longer up-to-date for many users.

The online workbook is aimed at pupils from grade 5 onwards in all types of schools. 

The aim of this online version is to provide an introduction to basic computer knowledge with practical and lesson-related exercises. These are intended to show the pupils the benefits of the programmes. At the same time, they should introduce them to the sophisticated operation of the programmes. Thus, pupils learn about elementary functions of presentation programmes with tasks such as "coordinate system" or "football field". Special emphasis is placed on imparting knowledge about the Internet, e-mail and social networks. They are to point out to pupils the dangers as well as the benefits of these media.
