Modeling: A computer science concept for general education

For all computer scientists the term `modeling' is well known. It displays an often-used method, which is applied in each field of computer science to investigate, describe and plan problems or structures. With the help of models, large and complex structures are divided into smaller parts, which leads to a better understanding of the problem and often provides input for the solution. With the help of different types of models, different perspectives of one problem can be observed and discussed. These processes are not only part of computer science respectively computational thinking. Problem solving skills are needed in any domain and should be trained as well as possible in primary and secondary education. This could be supported by the computer science concept of modeling including processes like reduction, decomposition, abstraction, generalization etc. and appropriate techniques like UML Unified Modeling Language or the Entity-relationship model. We suppose that a consequent use of modeling beginning in different subjects during primary and secondary education can train and improve problem-solving skills. Before being able to verify this hypothesis, it is necessary to find a way to integrate modeling in schools despite of not being part of the curriculum. This is one aim of our project “Informatics - A Child's Play”, which tries to implement different computer science concepts in different subjects of primary and secondary education. To reach this goal we firstly have to convince and train teachers. In this paper some topics of modeling are presented as they were adapted for workshops in primary and early secondary education considering the age and interests of the students as well as topics taken from their surroundings. Furthermore, we present first evaluation results concerning its acceptance and usefulness for teachers and students as well as their performance in understanding and applying modeling in different lessons.
