Publicación Vulnerability Assessment of Learning Management Systems(Institute of Electrical and Electronics Engineers (IEEE), 2023-03-21) San Cristóbal Ruiz, Elio; Pastor Vargas, Rafael; Gil Ortego, Rosario; Meier,Russ; Saliah-Hassane, Hamadou; Castro Gil, Manuel AlonsoThis paper presents a vulnerability assessment of a class of web applications designed to serve educational coursework to online users. We describe the deployment landscape, the known vulnerabilities institutions must be aware of, and document how non-supervised deployment puts institutions at risk from cybercriminals.Publicación 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.; Sancristobal, Elio; Castro Gil, Manuel AlonsoPeer 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.Publicación New scenarios and trends in non-traditional laboratories from 2000 to 2020(IEEE Xplore, 2024-04-10) Fernandez, Ricardo M.; García Loro, Félix; Alve, Gustavo; López-Rey García-Rojas, África; Meier, Russ; Castro Gil, Manuel AlonsoFor educational institutions in science, technology, engineering and mathematics (STEM) areas, the provision of practical learning scenarios is, traditionally, a major concern. In the 21st century, the explosion of information and communication technology (ICTs), as well as the universalization of low-cost hardware, has allowed the proliferation of technical solutions for any field, in the case of experimentation, encouraging the emergence and proliferation of nontraditional experimentation platforms. This movement has resulted in enriched practical environments, with wider adaptability for both students and teachers. In this article, the evolution of scholar production has been analyzed at the global level from 2000 to 2020. Current and emerging experimentation scenarios have been identified, specifying the scope and boundaries between them.Publicación Influence of Technological Resources on the Development of Mathematical Competence in High School(IEEE Xplore, 2021-03-01) Albert Gómez, María José; Blázquez Merino, Manuel; López-Rey García-Rojas, África; Castro Gil, Manuel AlonsoThe use of information and communication technologies in the process of learning through technological resources can be strongly motivating for students. The use of appropriate digital content through simulations and animations can facilitate the understanding of complex content. In this work, the incidence of the use of technological devices by students of the mathematics subject in Secondary Education in Madrid (Spain) is presented. Specifically, in relation to the use of an explanatory video made with the Camtasia application. The sample was of 31 students with a low level of competence in the subject. A quasi-experimental method of pretest/posttest design was used through an experimental group and a control group. Specific materials were designed and produced for this research. All these materials were subjected to expert judgement. The results show that the use of the instructional video was more than positive in the different variables under study.Publicación Overview of embedded systems to build reliable and safe ADAS and AD systems(IEEE (Institute of Electrical and Electronic Engineers), 2020-02) Belmonte, Francisco J; Martín Gutiérrez, Sergio; Sancristobal, Elio; Ruipérez Valiente, José A.; Castro Gil, Manuel AlonsoAutomotive industry is a key sector in developed countries, taking advantage from Electronic and Semiconductor industries, for which this work is focused on, including an overview of embedded systems and related technologies for Advanced Driver Assistance Systems (ADAS) development, end user applications and their implementation (SoCs, Application Processors-APs, MCUs, software and boards), manufacturers solutions, architectures, trends and other aspects (like methodologies) to improve functional safety, reliability and performances. The current status to permit the transition from ADAS to Autonomous Driving (AD) systems and Self-Driving Cars (SDC) is also explored.Publicación Dynamic reconfiguration in FPAA for technical and nontechnical education in a global environment(Wiley, 2021) Macho Aroca, Alejandro; García Teruel, Manuel; García Loro, Félix; Baizan, Pablo; Blázquez Merino, Manuel; Sancristobal Ruiz, Elio; Díaz Orueta, Gabriel; Gil Ortego, Rosario; Castro Gil, Manuel Alonso; https://orcid.org/0000-0003-3978-0692; https://orcid.org/0000-0002-5454-456X; https://orcid.org/0000-0001-5445-2377; https://orcid.org/0000-0003-0117-8794; https://orcid.org/0000-0002-6462-9196; https://orcid.org/0000-0003-2102-977XSome 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.
