On the Representation of Algorithmic Concepts
In the following paper we will report from the aspect of concept representation on fundamental experiments, which we have performed during the last few years. These experiments ask how thirteen-year-old pupils form concepts in the area of algorithms and in which way they use these concepts in problem solving. Our fundamental hypothesis is that the central problem in programming is to organize a sequence of actions which has to be executed by the computer. From this hypothesis we were led to develop didactical material and a suitable curriculum, by which pupils may readily acquire a fundamental insight in central concepts of automatization and computer programming (Cohors-Fresenborg, 1976, 1978; Cohors-Fresenborg,et al. 1982).
