| The use of the computer dynamic simulation environment, Vensim, to improve the learning of the concepts of limiting reactant and stoichiometry of the General Chemistry students at the University of Puerto Rico is presented. The objectives of this educational research are: use visualization tools to promote a deep learning of the course concepts, involve students in a more active way of learning, and introduce students since the first semester of Chemistry in dynamics aspects of chemical change. To accomplish this, Vensim dynamic graph activities includes: identification of the chemicals, determination of changes in moles of chemicals of the reaction, calculate the stoichiometric coefficient and limiting reactant problems. Through these activities a study of the dynamic effects of changing the different parameters associated was performed. An assessment of the process to establish the effectiveness of the activities was done and was compared with the students' academic performance in the class exams. |
