    (ELSEVIER, 2017) Ponce Jara, Marcos Antonio; Ruiz Larrocha, Elena; Gil Ortego, Rosario; Sancristóbal Ruiz, Elio; Pérez Molina, Clara María; Castro Gil, Manuel Alonso; https://orcid.org/0000-0002-4450-4740
    The modern struggle to generate electricity reducing our dependence on fossil fuels and decreasing greenhouse gas emissions has found an ally in Smart Grid technology. This new trend involves a renewed perspective on how to generate, transmit, distribute and manage electricity networks, which not only helps to reduce power demand and cost, but can also improve efficiency, reliability, quality and security. This paper aims to study comprehensively the Smart Grid power system by comparing experiences and success stories from around the world. Developed countries, like the United States and those in the European Union, and developing countries, like India and Brazil, have been taken as examples of the current development and state of the Smart Grid concept. Europe and the U.S. lead the development of Smart Grids systems, while Brazil and India strongly depend on foreign technology and investment for their development in their countries. Climate change represents an extra challenge for developing countries, in addition to other issues related to economic and social advancement. Nevertheless, Smart Grids offer an array of possibilities and opportunities that work towards climate change international goals. However, state motivations and national energy resources limit the advancement of Smart Grids on this matter.

    With the rapid proliferation of Internet of things (IoT) devices across various sectors, ensuring robust cybersecurity practices has become paramount. The complexity and diversity of IoT ecosystems pose unique security challenges that traditional educational approaches often fail to address comprehensively. Current curricula may provide theoretical knowledge but typically lack the practical components necessary for students to engage with real-world cybersecurity scenarios. This gap hinders the development of proficient cybersecurity professionals capable of securing complex IoT infrastructures. To bridge this educational divide, a remote online laboratory was developed, allowing students to gain hands-on experience in identifying and mitigating cybersecurity threats in an IoT context. This virtual environment simulates real IoT ecosystems, enabling students to interact with actual devices and protocols while practicing various security techniques. The laboratory is designed to be accessible, scalable, and versatile, offering a range of modules from basic protocol analysis to advanced threat management. The implementation of this remote laboratory demonstrated significant benefits, equipping students with the necessary skills to confront and resolve IoT security issues effectively. Our results show an improvement in practical cybersecurity abilities among students, highlighting the laboratory’s efficacy in enhancing IoT security education.

    (Wiley, 2019-06-28) Blázquez Merino, Manuel; Plaza, Pedro; López-Rey García-Rojas, África; Albert Gómez, María José; Castro Gil, Manuel Alonso; Sancristóbal Ruiz, Elio
    The research work hereby presented shows some findings about the different ways used by girls and boys, at secondary school, to assimilate the electricity concepts and electric magnitudes to be able to design and assemble electric circuits. The methodology applied to learning, the cognitive-motor model (CMM), is also presented, and it is based on the mutual interaction of cognitive skills and motor capabilities. Students have followed a specific course designed under CMM specifications. The course contains a combination of theoretical activities and practical tasks by means of which cognitive and motor skills have been measured. To carry out the practical tasks, the Virtual Instrument Systems in a reality remote lab have been used by students as the technical resource. In the study, different learning strategies between male and female students, what affects each gender effectiveness, and learning performance have been found.

    European Robotics Week to introduce robotics and promote engineering
    (Wiley, 2018-06-28) Plaza, Pedro; Carro Fernandez, German; García Loro, Félix; Blázquez Merino, Manuel; Castro Gil, Manuel Alonso; Sancristóbal Ruiz, Elio
    We present an activity framed within the European Robotics Week event. Robotics and computational practice are ideal tools for developing science, technology, engineering, and mathematics (STEM) pedagogy. A modular and adaptive hands-on workshop is described in detail. The workshop is based on multiplatform educational robotics content as a first step into the robotics world. Three educational tools are used to introduce examples of robotics applications. The operational details, materials, and examples of activities for selected modules are presented with the expectation that all teachers can adapt these activities to their classes. Despite the small number of students, the experience delivered results that might be useful for other instructors to promote workshops with similar or identical content to generate further benefits. This study demonstrates that it is important to combine theory and practice and include fun tasks that intertwine the challenges of applying theory to problem solving. Furthermore, the results show how the same content can be deployed using three different robotics education tools.

    Halloween Educational Robotics
    (IEEE Xplore, 2021-03-30) Menacho, Antonio; Plaza, Pedro; Pérez Molina, Clara María; Blázquez Merino, Manuel; Pancorbo Castro, Manuel; Sancristóbal Ruiz, Elio; https://orcid.org/0000-0001-5455-4250; https://orcid.org/0000-0003-2102-977X; https://orcid.org/0000-0001-8260-4155; https://orcid.org/0000-0003-3559-4235; https://orcid.org/0000-0001-5455-4250
    Today’s society is facing new challenges and opportunities that demand professional profiles specialized in problem solving, with the ability to innovate and exploit the possibilities offered by information and communication technologies (ICTs). Far from being a novelty, the term STEM was coined in the mid-1990s. From then until now, there are a multitude of initiatives focusing on working STEM education with students. In recent years, the use of the arts as an enhancer of the educational experience has been incorporated into STEM education. There has also been a focus on involving the student in the educational process. Despite this, few experiences have been detected in which parents are involved in the educational process. Throughout this work, it is shown the pilot experience which has been developed to motivate parents to be part of the learning process in science, technology, engineering, art, and mathematics (STEAM) subjects.

    Reviewing and analyzing peer review Inter-Rater Reliability in a MOOC platform
    (Elsevier, 2020-09) García Loro, Félix; Martín Gutiérrez, Sergio; Ruipérez Valiente, José A.; Castro Gil, Manuel Alonso; Sancristóbal Ruiz, Elio
    Peer assessment activities might be one of the few personalized assessment alternatives to the implementation of auto-graded activities at scale in Massive Open Online Course (MOOC) environments. However, teacher's motivation to implement peer assessment activities in their courses might go beyond the most straightforward goal (i.e., assessment), as peer assessment activities also have other side benefits, such as showing evidence and enhancing the critical thinking, comprehension or writing capabilities of students. However, one of the main drawbacks of implementing peer review activities, especially when the scoring is meant to be used as part of the summative assessment, is that it adds a high degree of uncertainty to the grades. Motivated by this issue, this paper analyses the reliability of all the peer assessment activities performed as part of the MOOC platform of the Spanish University for Distance Education (UNED) UNED-COMA. The following study has analyzed 63 peer assessment activities from the different courses in the platform, and includes a total of 27,745 validated tasks and 93,334 peer reviews. Based on the Krippendorff's alpha statistic, which measures the agreement reached between the reviewers, the results obtained clearly point out the low reliability, and therefore, the low validity of this dataset of peer reviews. We did not find that factors such as the topic of the course, number of raters or number of criteria to be evaluated had a significant effect on reliability. We compare our results with other studies, discuss about the potential implications of this low reliability for summative assessment, and provide some recommendations to maximize the benefit of implementing peer activities in online courses.

    Some engineering concepts have been proven to be very important not only in engineering degrees but in several areas. This knowledge is difficult to grasp under certain circumstances, and sometimes prior training is needed. This is a special challenge in full or part remote education. Simulations may help in this area, but truly experimental lab practices are crucial to grasp all the required knowledge and not only for fundamental information but for complex or indirect knowledge, where students can apply what they have learnt in classes. In this paper, we have worked on a concept to help professors and students to get new concepts in a more time-efficient and safe manner, using dynamic reconfiguration in Field-Programmable Analog Array. This solution can be easily applied to traditional or remote labs in less time than usual practices, so students can learn more in the same amount of time, especially when time is a constraint.
