Abstract
Mass transfer unit operations are of extreme importance to chemical engineers.
However, they involve complex and tedious calculations which provoke real fear
among the students who end up failing and, sometimes, quitting. The exclusive
use of hand calculations in engineering studies is discouraging, old‐fashioned,
and a primary source of mistakes. The integration of software packages very
much facilitates the calculations and engages the students. Computing skills
using the latest technologies are prized by employers and can be critical in a
recruitment process. This paper reports an example of the unique capabilities of
the Mathcad software for the implementation of more appealing teaching stra-
tegies. Unknowns and equations are easily associated with specific process
variables and engineering phenomena. Thus, if used conveniently, Mathcad
Prime can improve the students’ predisposition to learn.

1 | INTRODUCTION
Mass transfer operations constitute the basis of well‐
established separation procedures extensively used by the
chemical industry. Hence, a solid knowledge of mass
transfer processes is expected from a practicing chemical
engineer [24]. In many engineering courses, in general,
the difficulties experienced by the students very often
reside in the calculations rather than in understanding
the physical phenomena. Mass transfer operations in-
volve a number of complex mathematical operations like
simultaneous solution of nonlinear algebraic equations,
integral equations, ordinary or partial differential equa-
tions, numerical methods, and so forth. All these con-
tents are covered over the Bachelor's degree first course.
Even so, students not always attain a meaningful learning
because the unknowns are not associated with specific
process variables, neither are the equations to specific
engineering phenomena. Contextualization into real en-
gineering scenarios makes the students improve the un-
derstanding of the maths core principles and realize why
they need them [8].
Moreover, the traditional teaching practice is no longer
useful as such. The new students have grown up in a so-
ciety ruled by the massive use of technology, which changes
very fast [4]. Brown [5] stated that “today's digital kids think
of ICT (information and communication technologies) as
something akin to oxygen: they expect it, it's what they
breathe, and it's how they live.” In that sense, our experi-
ence tells us that the use of numerical and graphical hand
calculations discourages the students and makes them feel
uncomfortable. An approach based on the use of compu-
tational tools to put theoretical contents into practice can
make the classes more attractive to students.
The integration of the most advanced computational
tools into engineering courses is gaining acceptance over
