Abstract

MENDOZA, Dina; MARTINEZ, Juan M.  and  REALPE, Alvaro. Validation of didactic learning tool for the design of a binary mixing distillation tower by McCabe-Thiele. Form. Univ. [online]. 2020, vol.13, n.5, pp.147-154. ISSN 0718-5006.  http://dx.doi.org/10.4067/S0718-50062020000500147.

The objective of this work was to validate a didactic tool in the unit operations subject, to verify the achievement of meaningful learning in students on the subject of design of binary mixture distillation towers. The study was done at the Comfenalco Technological University Foundation and at the University of Cartagena (Colombia). Two groups were initially considered for validation, an experimental group using the didactic tool and a control without the tool. A measuring instrument was applied to assess the students at the start and the end of the activity. Data were analyzed using weighted and unweighted Gwet’s AC1 and Fleiss’ kappa agreement coefficients. It is concluded that using the validated software presented here improves the acquisition of meaningful learning in the teaching-learning process.

Keywords : meaningful learning; distillation tower design; didactic tool; McCabe-Thiele method.
