Abstract. In literature on chemistry education it has often been suggested that students, at high school level and beyond, can benefit in their studies of chemical kinetics from computer supported activities. Use of system dynamics modeling software is one of the suggested quantitative approaches that could help students develop knowledge about chemical kinetics and chemical equilibrium and remediate alternative conceptions. The methodology, strengths, and weaknesses of the implementation of graphical system dynamics software for modeling chemical kinetics are presented. An extension of classical graphical modeling is proposed that could make it easier for students to investigate chemical kinetics, especially in cases of non-trivial reaction mechanisms. Illustrative examples are given throughout the paper.
