Modeling of a Real Situation as a Method of the Algorithmic Thinking Development and Recursively Given Sequences

A method of developing students’ algorithmic thinking is demonstrated in the paper first. This is followed by an example of a physical problem step by step modeling and several approaches to its solution. These approaches demonstrate possible interdisciplinary learning, which is considered to be a very important part of future teachers’ education. Especially the relationship among physics, computer science and mathematics is introduced. Finally the benefit of CAS for explaining and visualizing recursively defined sequences is discussed. Key-Words: Algorithms, interdisciplinary learning, modeling, visualization, motivation, CAS, Maple, recursively defined sequence, linear recursive equation, logistic equation, cobweb plot, bifurcation diagram.
