Initial situation
• Informatics education in the Austrian curriculum since 1984
• Focus on programming and algorithmic concepts
• Overall educational value of CS rarely discussed• Most teachers have their key qualifications in
other domains• Now: educational goal Computer literacy

Motivation
• Status:– Computer science education – use of applications– Curricula left on a general level– Application-related concepts easier to teach– Difficult to „re-educate“ teachers– ECDL oriented lessons
• Aim:– Show core principles of informatics to pupils
AND to teachers

A look at 9th grade CS-lessons
• ECDL curriculum fills the informatics lessons
• Pupils associate informatics with „Word“, „text processing“, „Excel“, „boring“, „presentations“
• Distorted image of informatics as scientific discipline

Where to start from?
• Project Informatik erLeben• Set of interventions• Units for pupils from primary school up to
secondary school• Booklet and website with material for
teachers• Teachers observe and copy the units • Teachers are becoming multiplier for our idea

Aims
• Showing teachers that informatics is not all that difficult (to teach and to grasp)
• Showing teachers that pupils are not basically technology-averse
• Showing pupils, that informatics has to do much more with humans than with the machine

Principles of our concept
• Challenging the curiosity of the children
• Getting part of the underlying concept
• Active participation in games, animations, simulations
• Encourage active observation

Intermediate Evaluation
• Questionnaire with two questions to be answered in free text
• Observation of the pupil’s attention
• Review session with teachers and pupils
• Creation of questions to the topic by the children.

Review session with teachers and pupils
• Some teachers successfully transferred the approach to another class.
• Teachers and pupils would like to have more Informatik erLeben lessons.
• Only one teacher gave a clearly negative feedback.
• Some teachers made follow up lessons with their classes.
• The lecture part should not become too long.
![Page 20: Showing Core-Concepts of Informatics to Kids an their Teachers Roland Mittermeir Ernestine Bischof Karin Hodnigg Institut für Informatik-Systeme Universität](https://reader030.vdocuments.site/reader030/viewer/2022032803/56649e2d5503460f94b1cd74/html5/thumbnails/20.jpg)

Conclusions
• Success is easier reached with primary school kids (and teachers).
• Secondary school teachers already tried our approach on their own.
• One teacher even developed an extension to a unit.
• Interest and awareness have been created.
