Mediante la creación y refinamiento iterativo del código, se busca no solo aumentar la eficiencia y precisión de los cálculos, sino también incrementar la participación del alumnado. Para demostrar su potencial, se desarrolló en Excel un simulador con interfaz atractiva capaz de analizar condiciones óptimas y límites en una columna de destilación por etapas de equilibrio. Además, se empleó un ejercicio más sencillo en el aula para mostrar cómo la IA generativa puede integrarse de forma práctica en el proceso de aprendizaje.

The code can be iteratively refined until the desired functionality is achieved. This is not only intended to improve computational efficiency and accuracy but also to boost student engagement. To showcase the full potential of VBA scripting within spreadsheets, a simulator with an appealing interface was designed using Excel, such that optimal and limiting operating conditions were identified in an equilibrium-staged distillation column. Moreover, to underscore the pedagogical value of the approach at this exploratory stage of evaluating its educational scope, a much simpler classroom exercise was used to illustrate the hands-on integration of GenAI (Generative AI) into the learning process.engUpper-Division UndergraduateChemical EngineeringComputer-Based LearningMathematics/Symbolic MathematicsSeparation Sciencejournal article10.1021/acs.jchemed.5c01531embargoed access
