La Irresolubilitat dels problemes clàssics grecs. Recurs didàctic per a l'ensenyament i l'aprentatge

Actualment, a Catalunya, l'ordenació curricular integra el concepte de competència bàsica per establir com han de desenvolupar-se l'acció educativa i el procés d'ensenyament-aprenentatge, cosa que comporta la necessitat d'actualitzar els continguts i els recursos que s'estan emprant diàriament a les aules. Els nous recursos han d'estar definits i planificats en funció d'una sèrie de pautes com són: la concreció dels criteris metodològics, organitzatius i d'avaluació, la duració de cada activitat, la contextualització per reforçar els aprenentatges, les mesures adequades d'atenció a la diversitat i a la bona gestió de l'aula... En definitiva, la planificació prèvia dels recursos i la màxima concreció possible en la definició seran condicions necessàries, que no suficients, per a l'èxit de l'acció educativa. Entre altres tipus de continguts més teòrics i conceptuals (nombres, mesures, símbols, elements geomètrics, etc.), el currículum de l'assignatura de matemàtiques considera la història de les matemàtiques com un contingut més. I no aaatan sols contempla la història com un contingut, sinó que, a més, suggereix aproximacions de caràcter històric a determinats continguts teòrics matemàtics amb les quals es pretén mostrar el desenvolupament històric de les matemàtiques com a ciència en evolució i evidenciar contextos on els continguts adquiriren significat. La utilització de la història de les matemàtiques per dissenyar activitats té múltiples opcions: pot servir com a introducció d'un tema o d'un concepte nou, pot situar un concepte matemàtic en el temps, contribueix a fer l'aprenentatge més significatiu, ajuda a finalitzar una seqüència d'activitats, pot servir també per aprofundir en un tema concret i té la capacitat d'interrelacionar transversalment les diferents àrees de les matemàtiques. Veient la necessitat de crear nous recursos didàctics i aprofitant totes aquestes opcions que la història de les matemàtiques ens proporciona, es van crear les tres activitats proposades a partir de la «falsa» irresolubilitat dels problemes clàssics grecs.Currently in Catalunya, the «ordenació curricular» integrates the concept of «competència bàsica» to establish how they should develop educational activities and teaching-learning process, which implies the need to update the content and resources we are using every day in the classroom. The new resources must be defined and planned according to a series of guidelines as: specification of methodological, organizational and assessment criteria, the duration of each activity, the context to reinforce the learning, appropriate measures to attention to diversity and good classroom management ... In short, the pre-planning of resources and the highest possible precision in the definition be necessary, but not sufficient, for the success of an educational activity. Among other more theoretical and conceptual content (numbers, measurements, symbols, geometric elements, etc.), themathematics curriculum considers the history of mathematics as a content. And not only covers the history as a content, but also suggests a historical approach to certain theoreticalmathematics as an attempt to show the historical development ofmathematics as a science in evolution and demonstrate contexts where contents achievemeaningful. Using the history ofmathematics hasmany options for design activities: it can serve as an introduction to a topic or a new concept, amathematical concept can be located in time, help to make learningmoremeaningful, help to finish a sequence of activities, can also be used to further a particular topic and has the ability to interact across different areas ofmathematics. Seeing the need to create new educational resources and taking advantage of all the options that the history ofmathematics provides, three activities were created and proposed from the «dummy» insolvability of classical Greek problems

Innovando en el siglo XV: una propuesta de innovación docente en el Análisis filológico del Cuatrocientos

En este trabajo presentamos los cambios y avances metodológicos en la planificación de la asignatura Análisis filológico de textos hispánicos con especial atención a las innovaciones introducidas en el tema que trata el cambio lingüístico del siglo XV. Nuestro objetivo principal es dotar al alumno de herramientas procedimentales que le permitieran elaborar hipótesis sobre la datación de un documento desconocido a través del estado de lengua que presenta. Nos centramos, por tanto, en establecer un modelo metodológico basado en problemas con el fin de reforzar y afianzar la confianza del alumnado a la hora de elaborar hipótesis sobre lingüística diacrónica

Looking for students' enthusiasm: flipped classroom

The “flipped classroom” is a pedagogical model that consists of putting certain learning processes outside the classroom so that the teacher can devote more class time to students’ acquisition of practical skills, for example. In this way, the teacher is not limited to the transmission of course content, but in addition assumes the role of a mediator in the cognitive process, allowing students to actively construct their own knowledge. In this role, the teacher’s main task is to encourage students to become independent learners. This paper describes the implementation and initial results of the application of the flipped classroom in higher education. This study is part of a larger research project to improve our students’ motivation through the use of the flipped learning. The sample consisted of about 3000 students taking 17 different subjects, in Management and Administration Business, Finance and Accounting, Marketing and Market Research, and Chemistry, at the University of Málaga, and in Accounting and Administration, Business Communication and Marketing at the Polytechnic of Porto. According to our results, students’ motivation and class attendance increased with the application of this model; a comparison of the final exam results from two years with traditional classes and from two years with flipped learning shows that the proportion of students failing the exam decreased, which confirms that the use of this pedagogic model improves student learning.Universidad de Málaga.

Gamificacion in education and active methodologies at Higher education

In recent years, there has been an increasing interest in applying Gamification in Education, which can be defined as the application of game design elements to learning activities. Its purpose is to motivate students by creating an engaging learning experience that can keep students focused on the learning task and its application in the classroom, is still in its emergent stages. Gamification is a great challenge for education, particularly in Higher Education Institutions (HEI) in such a traditional context, as is the case with courses like Management and Administration Business, Finance and Accounting, Marketing and Market Research, Chemistry, Accounting and Administration and Business Communication. This paper presents a study, applied in the 2016/2017 and 2017/2018 academic years, in which the teaching method focuses on a blended learning approach, through the implementation of a flipped classroom model and also through the introduction of online gamification activities such Kahoot! application. Kahoot is a game-based learning platform, used as educational technology that can easily be used for initial, formative and summative assessment of students’ knowledge using individual or collaborative team work mode, adding vitality, student engagement, and also meta-cognitive supports to higher education classrooms with limited instructor or student training required. The participants, in the study, were about 3 000 students of 17 different subjects from the aforementioned courses, of the Malaga University and Polytechnic of Porto. The results of this study suggest that this model improves student learning and are of relevance to researchers, educators and game-based learning designers.Universidad de Málaga.

Tomografía corneal en pacientes intervenidos de LASIK con láser de femtosegundos. Estudio pre-operatorio y post-operatorio a los 3 meses

El objetivo principal del presente estudio consiste en diseñar un nuevo método para el análisis normalizado de mapas tomográficos y utilizarlo para comparar los mapas de pacientes antes de ser intervenidos mediante la técnica LASIK utilizando el láser de femtosegundos, y 3 meses después de la intervención. Para la realización del estudio se seleccionaron 50 ojos de 25 pacientes que tuviesen tomografías pre-cirugía y 3 meses después de la misma. A partir de ellas se tomaron los datos en 17 puntos corneales previamente definidos y los mismos en cada mapa: origen de coordenadas, 1, 2, 3, 4 mm temporal, nasal, inferior y superior. Dichos datos se volcaron en un archivo Excel para el posterior análisis. Los mapas corneales escogidos para el estudio fueron los de curvatura, elevación anterior y paquimetría. Se encontraron diferencias significativas (p<0.05) entre los valores pre y post-operatorios en todo el mapa de curvatura anterior y solamente en la parte temporal de curvatura posterior. En paquimetría, se encontraron diferencias en todo el mapa excepto a 4 mm del origen de coordenadas. Por otro lado, existe una correlación fuerte entre las diferencias pre y post-operatorias en el radio de los mapas de curvatura anterior y el equivalente esférico corregido (a mayor ablación, mayor diferencia) y sólo una correlación leve en paquimetría. Este estudio establece una nueva aproximación de medida para analizar mapas tomográficos, con unos puntos predefinidos en córnea que serán siempre los mismos, y que permite estudiar la superficie corneal de una forma más precisa y normalizada a las propuestas hasta el moment

An integrated targeted and untargeted approach for the analysis of ergot alkaloids in cereals using UHPLC - hybrid quadrupole time-of-flight mass spectrometry

An ultra-high performance liquid chromatography hybrid quadrupole time of flight (Q-TOF) mass spectrometry (MS) method is described for the simultaneous quantitative determination of common ergot alkaloids and the screening, detection and identification of unexpected (less studied or novel) members of this class of toxic fungal secondary metabolites. The employed analytical strategy involves an untargeted data acquisition (consisting of full scan TOF MS survey and information dependent acquisition MS/MS scans) and the processing of data using both targeted and untargeted approaches. Method performance characteristics for the quantitative analysis of 6 common ergot alkaloids i.e. ergometrine, ergosine, ergotamine, ergocornine, ergocristine, ergokryptine and their corresponding epimers in rye were comparable to those previously reported for triple-quadrupole (QqQ) MS/MS. The method limits of quantification (LOQ) were in the range from 3 to 19 mu g/kg, and good linearity was observed for the different ergot alkaloids in the range from LOQ to 1000 mu g/kg. Furthermore, the method demonstrated good precision (relative standard deviations at 50 mu g/kg not higher than 14.6 and 16.2% for the intra-day and inter-day precision, respectively), and the trueness values at different concentration levels were all between 89 and 115%. The method was applied for the analysis of a set of 17 rye samples and demonstrated the presence of these ergot alkaloids in the range from <LOQ to 2,811 mu g/kg. Further mining of the same data based on a 'non-targeted peak finding' algorithm and the use of full MS and MS/MS accurate mass data allowed the detection and identification of 19 ergot alkaloids that are commonly not included in most analytical methods using QqQ instruments. Some of these alkaloids are reported for the first time in naturally contaminated samples

How to scape from a killer fungus : a study of the epithelial microbiota as the main barrier to Batrachochytrium dendrobatidis infection

Amphibians are the world's most threatened class of vertebrates. Habitat loss and the emerging fungal infectious disease, chytridiomycosis, have been singled out as the causes that inflict the most damage on amphibian biodiversity. Chytridiomycosis is causing mass mortality and population declines worldwide. This disease is the greatest challenge for amphibian conservation as no proven implementable strategy in the field exists that can combat this disease. The community composition of the cutaneous microbiota has a strong effect on the morbidity caused by chytridiomycosis and is essential in the survival of the populations. The experiments proposed later try to recognize if different species of wild amphibians can promote beneficial anti-Bd bacteria when they are exposed to the fungus and acquire more information about the microbiota's role in the resistance of amphibians to chytridiomycosis
