[EN] The Engineering Education requires that students acquire an appropriate knowledge on a mathematical
computational language as well as on a numerical simulation procedure. The computational language of
mathematics usually is taught in advanced courses, once that the curriculum mathematical education is
mainly completed; in addition, the numerical simulation is usually located late or even in doctoral studies.
In this paper, we propose that the Computational Fluid Dynamics (CFD) become to be a teaching-learning
tool, instead of a strategic resource only. CFD can be regarded as a transversal skill i.e., as a useful educational
tool for the Hydraulic Turbomachines learning, which achieves to overcome some epistemological

[EN] Virtual labs can be adopted as a complement of the university traditional teaching methodologies. This
paper describes the results of a teaching pilot project which enabled the use of a commercial processsimulator
(Hysys) in the implementation of five virtual labs related to three important unit operations in
Chemical Engineering: liquid-liquid extraction, distillation, and heat exchange. The software provided a
new approach to the analysis and interpretation of lab results by students. The educational effectiveness
of the implemented project was evaluated through questionnaires, and the results showed that in average
more of 85% of the student considered Hysys of great utility in their learning process. Project...

[EN] Linear Elasticity is a discipline that studies the elastic solids which generate a mechanical response in
linear elastic regime under external forces. In particular, is of special interest to study the stresses and
strains at any point of the solid, which is known as the elastic problem. In Elasticity it is necessary to
know the so-called state of stress in the differential environment of a point of the elastic solid, and also
the associated deformations.
To this end, in this paper we present the virtual laboratories TENSIONES and DEFORMACIONES,
made with the package Matlab through its graphical user interface (GUI). These two virtual laboratories

[EN] Nonlinear Programming (NLP) is a widely applicable tool in modeling real life problems
applied to business, economics and engineering. Is to maximize or minimize a scalar
field whose domain is given as a set of constraints given by equalities and/or inequalities
not necessarily linear. In this paper we present a virtual laboratory to study the PNL
graphically and numerically in the case of two variables

[EN] The Kriging is an interpolation method which in practical terms is to find the best estimate
of the value of a variable. For this weighting performed, ie a weight attached to each
measured value so as to minimize the variance of the estimation error. In this paper we
present a virtual laboratory to study from a teaching perspective this technique in the case
of dimension two.

[EN] The software used for making educational tools allows analyze the engineering phenomena in a more
complete and explained way, by means of simulation and experimentation. It is necessary to know the
equations about the behaviour of the object under study for the generation of these tools, and to solve
them through the right software, obtaining the output values from the input values. With this software it
is possible to realize new studies only modifying the parameters of the model or the input values. In this
work the alternating current electric circuits are analyzed. Joined with the simulation, this technology
also allows the experimentation through the...

[EN] Celtic or Rattleback Stone is a solid that if it is rotated as top exhibits a surprising behaviour.
Using a stereoscopic camera and digital monitoring techniques, we capture its
movement. According the laws of classical mechanics, justify its evolution “rattling” and
emphasize the high didactic potential that have these amazing systems for engineering students.

[EN] In the present article, a methodology for teaching modeling problem of mixed torsion for thin-walled open
sections. The mathematical analogy of warped twist as a problem of Euler-Bernoulli beams is exploited. In
fact, the paper proposes to represent the warped torsion differential equation as a perturbation of the pure
torsion or also called the Saint-Venant theory. Thus, it is demonstrated that under certain conditions
related to the value of the torsional slenderness the response of a beam is the addition of infinite pure
warped problems, that is, infinite bending problems, according to the analogy. We call this the asymptotic

[EN] In this paper we describe the process of designing and developing of interactive digital resources adapted to each student. It is shown the process which the authors have followed during the last years in order to generate virtual learning objects for the learning and teaching of Statistics. It is also shown the main features that the digital resources must fulfil and the different possibilities of use. Finally we describe the advantages of the designing of digital resources using author tools, and the integration of several tools as LaTeX, R, GeoGebra, etc. which let us obtain educational resources adaptable for...

[EN] There exists a wide range of CAD systems devoted to model three-dimensional objects. Based on an
intuitive creation and transformation of basic geometrical objects, the mathematical foundation of such
systems is generally unknown to their users. The incorporation of this kind of software in Math classes is
a fundamental key to get the attention of students of those degrees for which CAD systems are not only
attractive, but also extremely important in the future professional career. The current paper deals with
the experience carried out in this regard during the last five years by students of the Building Engineering
Degree of the University of Seville....

[EN] In this study we present an experience carried out in an 11th grade class. We use a teaching
model designed to work the concepts of family of functions and parameter through the
modelling. This model has the characteristic that the data are obtained by students in
classroom using tablets and it includes elements that allow them to manage the modelling
process. The analysis of the results revealed that the realization of a previous qualitative
analysis of the phenomenon studied and the students’ knowledge about the families of functions
and the meaning of the parameters are key elements in the management and control
of the entire process....
[EN] Mechanical vibrations as subject can be found within many Engineering and Science Degrees.
To achieve that the students understand the mathematics and its physical interpretation
is the objective we should get as docents. In this paper we describe how to create a
simple graphical model of a single degree of freedom vibrating system allowing us to visualize
concepts like above concepts damping, resonance or forced vibrations. For that, we
use the popular symbolic software Wolfram Mathematica with which, without an excessive
programming complexity, we can obtain a very satisfactory visual model capable to move
itself, controlled by parameters. In addition, the model incorporates the curve-response,
