La evaluación de las competencias específicas en titulaciones técnicas suele ser sumativa y articulada en pruebas escritas y memorias a entregar mayoritariamente al finalizar el periodo docente. Los alumnos concentran el estudio entorno a las evaluaciones, con poco margen para “corregir su aprendizaje” y asentar conceptos. El presente trabajo se enmarca en un proyecto de innovación y mejora educativa centrado en el diseño e implantación de actividades de evaluación formativa, orientadas al aprendizaje de competencias específicas en el ámbito de la electrónica. En él participa la asignatura Instrumentación y Control Industrial (ICI), troncal del Máster en Ingeniería Industrial con más de 300 alumnos. Mediante un cuestionario de 21 preguntas se ha analizado el estado actual de ICI respecto del aprendizaje de competencias específicas: seguimiento y tiempo dedicado por los alumnos, metodologías docentes preferidas, conceptos más difíciles de asimilar y valoración de la realimentación recibida. Se obutvo que un 44% de los alumnos concentra su estudio en las semanas próximas a la evaluación. Sólo el 12% ha concertado tutorías. El 55% considera que la realimentación de las actividades es insuficiente, valoran positivamente el aprendizaje basado en problemas (68%), poco la lección magistral (6%) y consideran que ICI les ha permitido mejorar las competencias asociadas al diseño de cadenas de medida industriales. Esta información ha conllevado el rediseño de la asignatura, incluyendo actividades de evaluación formativa basadas en problemas a implantar el próximo curso 22-23.------------------------------------------------------------------------------The evaluation of specific skills in technical degrees is usually summative and articulated in written tests and reports to be delivered mostly at the end of the teaching period. The students concentrate the study around the evaluations, with little margin to “correct their learning” and establish concepts. This work is part of an educational innovation and improvement project focused on the design and implementation of formative assessment activities, aimed at learning specific skills in the field of electronics. The Industrial Instrumentation and Control (ICI) subject, compulsory in the Industrial Engineering Master with more than 300 students, participates in it. Through a questionnaire of 21 questions, the current state of ICI regarding the learning of specific competences has been analyzed: “tracking” and time dedicated by students, preferred teaching methodologies, concepts that are more difficult to assimilate and assessment of the feedback received. It was found that 44% of the students concentrate their study in the next few weeks to the evaluation. Only 12% have arranged tutorials. 55% consider that the feedback of the activities is insufficient, positively value problem-based learning (68%), less master class (6%) and consider that ICI has allowed them to improve the skills associated with the design of measurement chains industrial. This information has led to the redesign of the subject, including formative evaluation activities based on problems to be implemented next academic year 22-23.
La capacidad de búsqueda y valoración de la información y el aprendizaje autónomo de estudiantes y profesionales son de gran relevancia en una sociedad en la que el conocimiento es amplísimo y se genera de forma muy rápida. Con objeto de trabajar estos aspectos relacionados con la competencia aprender a aprender (AaA) y la gestión de la información se desarrollaron materiales (documentación en texto y vídeos) y actividades formativas, que se implantaron en asignaturas del ámbito de la electrónica del Grado de Ingeniería Biomédica. En 3º curso con énfasis en la búsqueda y evaluación de la información y en 4º curso incorporando énfasis en la gestión de dicha información. Asimismo, se generaron rúbricas para la valoración de los aspectos más relevantes y se diseñaron sesiones de evaluación entre pares. Para valorar los resultados de las actividades y materiales desarrollados en este curso, se realizaron encuestas de autoevaluación de la competencia AaA en general, específicas de gestión de la información y sobre las propias actividades; además se realizó una sesión de ‘focus group’. Los resultados muestran una mejora en aspectos como su capacidad de buscar y seleccionar información para estudiar las asignaturas, el pensamiento crítico o en el manejo de TICs. Asimismo, los estudiantes realizan búsquedas de información de forma más habitual; también aumenta la frecuencia en que emplean herramientas para el refinado de búsqueda, repositorios especializados y contrastan la fiabilidad de la fuente. Además, el alumnado muestra una gran satisfacción en general con los materiales y actividades y recomienda su aplicación en otros cursos y ámbitos.------------------------------------------------------------------------------The ability to search for and evaluate information and the autonomous learning of students and professionals are highly relevant in a society in which knowledge is vast and is generated very quickly. In order to work on these aspects related to the learning to learn (LtL) competence and information management, materials (documentation in text and videos) and training activities were developed and implemented in subjects in the field of electronics of the Biomedical Engineering Degree. In the 3rd course with emphasis on the search and evaluation of information and in the 4th course incorporating emphasis on the information management. Likewise, rubrics were generated for the assessment of the most relevant aspects and peer evaluation sessions were designed. To assess the results of the activities and materials developed in this course, self-assessment surveys were carried out on the LtL competence in general, information management in particular and on the activities themselves; in addition, a focus group session was held. The results show an improvement in aspects such as their ability to search for and select information to study the subjects, critical thinking or ICT management. Likewise, students search for information more frequently; it also increases the frequency with which they use search refinement tools, specialized repositories and verify the reliability of the source. In addition, the students show great satisfaction in general with the materials and activities and recommend their application in other courses and areas.

Two new surrogate methods, the Small Shuffle Surrogate (SSS) and the Truncated Fourier Transform Surrogate (TFTS), have been proposed to study whether there are some kind of dynamics in irregular fluctuations and if so whether these dynamics are linear or not, even if this fluctuations are modulated by long term trends. This situation is theoretically incompatible with the assumption underlying previously proposed surrogate methods. We apply the SSS and TFTS methods to microelectrode recording (MER) signals from different brain areas, in order to acquire a deeper understanding of them. Through our methodology we conclude that the irregular fluctuations in MER signals possess some determinism.
A methodology for identifying brain areas from the brain MER signals (microelectrode recordings) is presented, which is based on a nonlinear feature set. We propose nonlinear dynamics measures such as correlation dimension, Hurst exponent and the largest Lyapunov exponent to characterize the dynamic structure. The MER records belong to the Polytechnical University of Valencia, 24 records for each zone (black substance, thalamus, subthalamus nucleus and uncertain area). The detection of each area using characteristics derived from complexity analysis was obtained through a classifier (support vector machine). The joint information between areas is remarkable and the best accuracy result was 93.75%. The nonlinear dynamics techniques help to discriminate the four brain areas considered, since they take into account the intrinsic dynamics of the signals and the structures analysis based on the multivariate statistical procedures is an important step in the data preprocessing.
