A Pragmatic Framework for Assessing Learning Outcomes in Competency-Based Courses
(Institute of Electrical and Electronics Engineers, 2024-01-19) Vargas Oyarzún, Héctor; Heradio Gil, Rubén; Farias, Gonzalo; Lei,,Zhongcheng; Torre Cubillo, Luis de la
Contribution: A competency assessment framework that enables learning analytics for course monitoring and continuous improvement. Our work fills the gap in systematic methods for competency assessment in higher education. Background: Many institutions are shifting toward competency-based education, thus encouraging their educators to start evaluating their students under this paradigm. Previous research shows that structured assessment models are fundamental in guiding educators toward this adoption. Intended outcomes: An assessment model for competency-based education that is easy to adopt and use, while facilitating the application of learning analytics techniques. Application design: The new framework considerably extends a prior model we proposed three years ago. Two engineering competency-based courses used the framework for assessment. Assessment rubrics were prepared and used for evaluating and collecting the students’ data progressively, thus enabling the use of learning analytics for decision-making. Findings: Thanks to the model, (i) students received a detailed report of their achievements, including a thorough explanation and justification of the evaluation criteria; and (ii) instructors could improve the course and provide objective evidence of their actions to quality assurance agencies. As a result, the framework is presently being used in fifteen courses taught at eight different university degrees at the Pontifical Catholic University of Valparaiso (PUCV).
Adding automatic evaluation to interactive virtual labs
(Taylor and Francis Group, 2015-04-07) Farias, Gonzalo; David Muñoz de la Peña; Fabio Gómez-Estern; Torre Cubillo, Luis de la; Gómez Sánchez, Carlos; Dormido Canto, Sebastián
Automatic evaluation is a challenging field that has been addressed by the academic community in order to reduce the assessment workload. In this work we present a new element for the authoring tool Easy Java Simulations (EJS). This element, which is named automatic evaluation element (AEE), provides automatic evaluation to virtual and remote laboratories built with EJS by using the server application Goodle grading management system (GMS). The integration of both tools entitles a professor to create interactive virtual and remote laboratories and automatically evaluate the work of their students. As a test bed two case studies are presented; a non-linear controller design virtual laboratory used in an advanced control master course and a servomechanism virtual laboratory used in an undergraduate basic control course.
Aproximación al uso de blockchain para la gestión de accesos a laboratorios en línea
(Universidad Nacional de Educación a Distancia (UNED) E.T.S. de Ingeniería Informática. Departamento de Informática y Automática, 2023-09-19) Ramos Villalón, Juan Luis; Torre Cubillo, Luis de la
El uso de laboratorios en línea para la enseñanza de la ciencia y la tecnología lleva creciendo y evolucionado intensamente en las dos últimas décadas. Disponer de estos recursos a través de Internet permite que las instituciones propietarias puedan colaborar entre ellas compartiéndolos o cediendo su uso a cambio de un desembolso económico. En paralelo, los avances en el desarrollo de las tecnologías blockchain más allá de las criptomonedas y su capacidad para generar aplicaciones descentralizadas, así como la necesidad creciente de securizar el acceso de forma automatizada a dispositivos autónomos conectados (IoT), se puede hacen converger para gestionar la publicación y acceso a los laboratorios en línea y efectuar intercambio de fondos en la transacción de forma nativa. En este trabajo se hace una revisión del estado del arte de los componentes antes mencionados. Se considera a los laboratorios en línea como objetos de aprendizaje y a la vez como sistemas ciberfísicos, se revisan algunas técnicas de control de acceso a activos digitales y la forma en que se pueden utilizan las cadenas de bloques para gestionar esa funcionalidad, así como los enfoques que se están utilizando al aplicar estas técnicas en los ecosistemas IoT. Se ha elaborado una pequeña prueba de concepto con herramientas de software libre en la que se simula la publicación, reserva y acceso a laboratorios en línea con intercambio de fondos. Finalmente, tras las conclusiones, se plantean líneas de trabajo futuro, profundizando en la modelización del problema planteado y su solución.
Assisted Creation and Deployment of Javascript Remote Experiments
(International Federation of Engineering Education Societies, 2016-09-28) Torre Cubillo, Luis de la; Faustino Andrade, Tiago; Sousa, Pedro; Sanchez, Jose; Restivo, Maria Teresa
In order to disseminate and encourage the use of remote experiments, their creation and deployment need to be simplified. This work presents a method to easily develop remote experiments interfaces in Javascript and to quickly embed them in Moodle. This solution requires the use of Easy Java/Javascript Simulations for the development of the interfaces and the EJSApp Moodle plugin to deploy them in the web platform. The proven flexibility of such solution has fostered the integration of two new experiments and also the easy adaptation of an already existing one, opening new remote labs flexibility to educational and/or training activi- ties.
Automated assessment and monitoring support for competency-based courses
(IEEE Xplore, 2019-03-28) Vargas, Héctor; Heradio Gil, Rubén; Chacón, Jesús; Torre Cubillo, Luis de la; Farias, Gonzalo; Galán, Daniel; Dormido Canto, Sebastián
Competency-based education is becoming increasingly adopted by higher education institutions all over the world. This paper presents a framework that assists instructors in this pedagogical paradigm and its corresponding open-source implementation. The framework supports the formal definition of competency assessment models and the students' evaluation under these models. It also provides distinct learning analytics for identifying course shortcomings and validating corrective actions instructors have introduced in a course. Finally, this paper reports the benefits of applying our framework to an engineering course at the Pontifical Catholic University, Valparaíso, Chile for three years.
Automatic Generation and Easy Deployment of Digitized Laboratories
(IEEE, 2020-12-01) Torre Cubillo, Luis de la; Neustock, Lars Thorben; Herring, George K.; Chacon, Jesus; García Clemente, Félix J.; Hesselink, Lambertus
This article presents a general way to enable automatic generation of digitized laboratories (a sort of digital twin for laboratory experimental setups) from remote laboratories and their easy deployment and publication. To demonstrate its effectiveness, we use two existing tools to generate and publish two digitized laboratories online from two implementations of a Snell's law remote laboratory, although they could be applied to many other remote laboratories. The first of these tools is a communication protocol that was designed to manipulate laboratory equipment through the Internet. This protocol can be used to automatically loop through different possible laboratory states and store them. The second one is a web platform that allows uploading files, that contain data sets of the laboratory states, to publish the digitized laboratory as a web application that is generated automatically.
The Ball and Beam System: A Case Study of Virtual and Remote Lab Enhancement With Moodle
(IEEE (Institute of Electrical and Electronics Engineers), 2015-06-10) Torre Cubillo, Luis de la; Guinaldo Losada, María; Heradio Gil, Rubén; Dormido Canto, Sebastián
Web-based labs are key tools for distance education that help to illustrate scientific phenomena, which require costly or difficult-to-assemble equipment. Easy Java Simulations (EJS) is an authoring tool that speeds up the creation of these kind of labs. An excellent proof of the EJS potential is the open source physics (OSP) repository, which hosts hundreds of free EJS labs. Learning management systems, such as Moodle, provide social contexts where students interact with each other. The work described in this paper looks for the synergy of both tools, EJS and Moodle, by supporting the deployment of EJS labs into Moodle and thus enriching them with social features (e.g., chat, forums, and videoconference). To test this approach, the authors have created the ball and beam lab, which helps students of automatic control engineering to train different advanced techniques (robust, fuzzy, and reset control), and compare their performance in relation to a conventional proportional-integral-derivative control.

(ELSEVIER, 2023-03-17) Rossiter, John Anthony; Cassandras, Christos G.; Hespanha, João; Dormido Canto, Sebastián; Torre Cubillo, Luis de la; Ranade, Gireeja; Visioli, Antonio; Hedengren, John; Murray, Richard M.; Antsaklis, Panos; Lamnabhi Lagarrigue, Francoise; Parisini, Thomas
This article focuses on extending, disseminating and interpreting the findings of an IEEE Control Systems Society working group looking at the role of control theory and engineering in solving some of the many current and future societal challenges. The findings are interpreted in a manner designed to give focus and direction to both future education and research work in the general control theory and engineering arena, interpreted in the broadest sense. The paper is intended to promote discussion in the community and also provide a useful starting point for colleagues wishing to re-imagine the design and delivery of control-related topics in our education systems, especially at the tertiary level and beyond.
Customized Online Laboratory Experiments: A General Tool and Its Application to the Furuta Inverted Pendulum [Focus on Education]
(Institute of Electrical and Electronics Engineers (IEEE), 2019-09-17) Galán Vicente, Daniel; Chaos García, Dictino; Torre Cubillo, Luis de la; Aranda Escolástico, Ernesto; Heradio Gil, Rubén
Because of online laboratories (labs), students can perform experimental activities from their mobile devices and/or computers. This article proposes an experimentation environment (EE) that extends the capabilities of interactive online labs with scripting language support. Thus, control engineering students can specify complex experiments, avoid routine tasks, and empirically test controllers they made themselves.
A decentralised approach to cyber-physical systems as a service: Managing shared access worldwide through blockchain standards
(ELSEVIER, 2025-02-18) Ramos Villalon, Juan Luis; Torre Cubillo, Luis de la; Lei, Zhongcheng; Hu, Wenshan; Tadashi Kussaba, Hugo; Lemieux, Victoria
Cyber-physical systems (CPSs) is a general concept that encompasses a wide variety of systems. Depending on their nature, application, and accessibility needs and restrictions, CPSs can differ a lot from each other. This paper proposes a classification of CPSs based on their accessibility needs and restrictions and, more importantly, presents an approach to create a decentralised and worldwide common access management framework for CPSs for non-critical infrastructures that are meant to be shared and accessed remotely (i.e., offered as a service). The presented solution uses a permissionless blockchain, existing fungible tokens, and a combination of smart contracts based on nonfungible token standards/proposals to enable CPS owners to manage secure, flexible access without centralised oversight. In addition, the proposed framework provides built-in mechanisms for: (i) charging for the use of CPSs, (ii) availability calendar configuration, (iii) worldwide visibility, (iv) easy integration with authentication/authorisation methods, and (v) access control flexibility.
Design of a low-cost air levitation system for teaching control engineering
(MDPI, 2017-10-12) Chacón, Jesús; Sáenz Valiente, Jacobo; Torre Cubillo, Luis de la; Díaz Martínez, José Manuel; Esquembre, Francisco; MDPI
Air levitation is the process by which an object is lifted without mechanical support in a stable position, by providing an upward force that counteracts the gravitational force exerted on the object. This work presents a low-cost lab implementation of an air levitation system, based on open solutions. The rapid dynamics makes it especially suitable for a control remote lab. Due to the system’s nature, the design can be optimized and, with some precision trade-off, kept affordable both in cost and construction effort. It was designed to be easily adopted to be used as both a remote lab and as a hands-on lab.
An event-based adaptation of the relay feedback experiment for frequency response identification of stable processes
(Elsevier, 2023-04-13) Sánchez Moreno, José; Torre Cubillo, Luis de la; Chacón Sombría, Jesús; Dormido Canto, Sebastián; Elsevier; https://orcid.org/0000-0003-0898-3462
An event-based modification of the classical relay feedback experiment without the inclusion of additional elements (integrator, time delay, . . . ) for identification of the spectrum of stable processes between zero and the phase cross-over frequency is presented. By inserting an event-based sampler in the control loop, the natural behaviour of a classical relay is simulated and the system is forced to work in two modes. The event-based sampler activates the first mode by sending control actions to the process every time the error signal crosses zero; this mode is to discover the approximated value of the cross-over frequency ω180◦ . During the second mode, the event-based sampler sends samples to the process simulating that the error signal crosses zero at ω180◦ /N where N is the number of points to identify in the range 0 ≤ ω ≤ ω180◦ . One advantage of this procedure is that the logic used in an already existing relay feedback experiment to fit a transfer function model or tune a controller could be maintained just replacing the relay block by the event-based sampler block presented in the paper. Simulations and experiments with different processes and in presence of noise demonstrate the effectivity of the procedure.
Evidence-Based Control Engineering Education: Evaluating the LCSD Simulation Tool
(IEEE, 2020-09-25) Marin, Loreto; Vargas, Héctor; Heradio Gil, Rubén; Torre Cubillo, Luis de la; Díaz Martínez, José Manuel; Dormido Canto, Sebastián
The advance in control engineering education needs well-designed studies that validate what methods and tools work best. This paper addresses the lack of empirical evidence supporting innovations in control engineering education by proposing a methodology that works at different abstraction levels. Hence, innovations' impact on students' performance can be statistically analyzed either globally or locally by examining competencies or fine-grained indicators, respectively. The article reports the application of the methodology for evaluating an interactive simulation tool, named LCSD, on 101 students at the Pontifical Catholic University of Valparaiso in Chile. According to the experimental results, LCSD is an effective free alternative to enhance the student's skills on control system analysis for our automatic control course. Also, some improvements have been identified for future LCSD versions.
Evolutionary Trajectory Planner for Multiple UAVs in Realistic Scenarios
(IEEE Xplore, 2010-05-24) Besada Portas, Eva; Torre Cubillo, Luis de la; de la Cruz, Jesús M.; de Andrés-Toro, Bonifacio
This paper presents a path planner for multiple unmanned aerial vehicles (UAVs) based on evolutionary algorithms (EAs) for realistic scenarios. The paths returned by the algorithm fulfill and optimize multiple criteria that 1) are calculated based on the properties of real UAVs, terrains, radars, and missiles and 2) are structured in different levels of priority according to the selected mission. The paths of all the UAVs are obtained with the multiple coordinated agents coevolution EA (MCACEA), which is a general framework that uses an EA per agent (i.e., UAV) that share their optimal solutions to coordinate the evolutions of the EAs populations using cooperation objectives. This planner works offline and online by means of recalculating parts of the original path to avoid unexpected risks while the UAV is flying. Its search space and computation time have been reduced using some special operators in the EAs. The successful results of the paths obtained in multiple scenarios, which are statistically analyzed in the paper, and tested against a simulator that incorporates complex models of the UAVs, radars, and missiles, make us believe that this planner could be used for real-flight missions.
Exemplar driven development of software product lines
(Elsevier, 2012-12-01) Heradio Gil, Rubén; Fernández Amoros, David José; Torre Cubillo, Luis de la; Abad Cardiel, Ismael
The benefits of following a product line approach to develop similar software systems are well documented. Nevertheless, some case studies have revealed significant barriers to adopt such approach. In order to minimize the paradigm shift between conventional software engineering and software product line engineering, this paper presents a new development process where the products of a domain are made by analogy to an existing product. Furthermore, this paper discusses the capabilities and limitations of different techniques to implement the analogy relation and proposes a new language to overcome such limitations.
The experiment editor: supporting inquiry-based learning with virtual labs
(IOP Science, 2017-03-08) Galán, Daniel; Heradio Gil, Rubén; Torre Cubillo, Luis de la; Dormido Canto, Sebastián
Inquiry-based learning is a pedagogical approach where students are motivated to pose their own questions when facing problems or scenarios. In physics learning, students are turned into scientists who carry out experiments, collect and analyze data, formulate and evaluate hypotheses, and so on. Lab experimentation is essential for inquiry-based learning, yet there is a drawback with traditional hands-on labs in the high costs associated with equipment, space, and maintenance staff. Virtual laboratories are helpful to reduce these costs. This paper enriches the virtual lab ecosystem by providing an integrated environment to automate experimentation tasks. In particular, our environment supports: (i) scripting and running experiments on virtual labs, and (ii) collecting and analyzing data from the experiments. The current implementation of our environment supports virtual labs created with the authoring tool Easy Java/Javascript Simulations. Since there are public repositories with hundreds of freely available labs created with this tool, the potential applicability to our environment is considerable.

The impact of take-home laboratories on student perceptions of conceptual and professional learning in electronic engineering across four European universities
(Taylor & Francis, 2024-09-27) O’Mahony, Tom; Hilla, Martin; Onet, Raul; Neag, Marius; Torre Cubillo, Luis de la; Zhou, Dao
Research exploring the advantages and limitations of different laboratory modes on student learning is critical so that engineering instructors can design hybrid/blended laboratories to maximise student learning. However, limited research explores the impact of take-home laboratories on student learning. This article documents the impact that the "HELP" take-home laboratory had on student perceptions of conceptual and professional learning across four European universities within the discipline of electronic engineering. Impact was evaluated through a student questionnaire that included Likert-scale and open-ended questions and was completed by 74 participants. The research extends what is known by revealing how take-home laboratories supported student understanding. Participants report that having flexible access and more time to build and test real circuits enhanced their understanding. Participants also reported that take-home laboratories supported the development of specific professional skills. Based on the student perspective, an implication of this research is that take-home laboratories can legitimately complement other laboratory modalities.
Improving the accuracy of COPLIMO to estimate the payoff of a software product line
(Elsevier, 2012-07) Heradio Gil, Rubén; Fernández Amoros, David José; Torre Cubillo, Luis de la; Alberto Perez Garcia-Plaz
Software product line engineering pursues the efficient development of families of similar products. COPLIMO is an economic model that relies on COCOMO II to estimate the benefits of adopting a product line approach compared to developing the products one by one. Although COPLIMO is an ideal economic model to support decision making on the incremental development of a product line, it makes some simplifying assumptions that may produce high distortions in the estimates (e.g., COPLIMO takes for granted that all the products have the same size). This paper proposes a COPLIMO reformulation that avoids such assumptions and, consequently, improves the accuracy of the estimates. To support our proposal, we present an algorithm that infers the additional information that our COPLIMO reformulation requires from feature diagrams, which is a widespread notation to model the domain of a product line.
