The book describes goals and success criteria of early computer science education at pre-primary and primary school age. Two expert reports specify pedagogical content dimensions of computer science education and give recommendations for the further development of the “Haus der kleinen Forscher” Foundation’s offerings. The implementation of these professional recommendations in the programmes of the “Haus der kleinen Forscher” Foundation is also described. In their expert report, Nadine Bergner, Hilde Köster, Johannes Magenheim, Kathrin Müller, Ralf Romeike, Ulrik Schroeder and Carsten Schulte specify the pedagogical and content-related target dimensions of computer science education at early childhood education and care centres, after-school centres, and primary schools. In addition to a theoretical basis for various target dimensions, the authors discuss the success criteria for effective and efficient early computer science education in practise. They also give recommendations for the further development of the „Haus der kleinen Forscher“ Foundation’s offerings and scientific monitoring of the work of the Foundation in the field of computer science. In their expert recommendation, Nadine Bergner and Kathrin Müller describe a selection of informatics systems for children at early childhood education and care centres and primary schools and give suggestions for particularly suitable systems and their use in pre-primary and primary education on the basis of expert criteria. The English version is a partially revised edition of "Stiftung Haus der kleinen Forscher (Hrsg.) (2018). Frühe informatische Bildung – Ziele und Gelingensbedingungen für den Elementar- und Primarbereich. Wissenschaftliche Untersuchungen zur Arbeit der Stiftung „Haus der kleinen Forscher“ (Band 9). Opladen, Berlin, Toronto: Verlag Barbara Budrich. The information has been updated to new developments and offerings of the “Haus der kleinen Forscher” Foundation.
