La “uberización” de los centros escolares: reorganización del trabajo pedagógico mediante las plataformas digitales de contenidos
2018
El presente trabajo se inscribe en el marco de un proyecto de investigación de I+D que estudia los cambios producidos en los centros de Primaria por la progresiva sustitución de los libros de texto por los materiales digitales. Uno de esos cambios observados es que los materiales digitales se hacen operativos mediante plataformas digitales que, además, se hacen extensibles a otras muchas tareas de centro. A partir de esta constatación nos ocupamos aquí del estudio de la 'uberización' o reestructuración organizativa del trabajo en los centros que operan con estas plataformas. Para alcanzar tal objetivo hemos recurrido a una metodología de corte cualitativo, tanto para el análisis de la prese…
Evaluation of the force generated by gradual deflection of 0.016-inch NiTi and stainless steel orthodontic wires in self-ligating metallic and esthet…
2019
Background The purpose of this study was to evaluate the deflection forces of 0.016-inch Nitinol and stainless steel orthodontic wires, in association to different self-ligating brackets. Material and Methods Specimens were mounted in a clinical simulation model and evaluated in a Universal Testing Machine (INSTRON 3342), using a 10N load cell and ISO 15,841, as a protocol. Eight of these models were prepared, each one for the bonding of each set of self-ligating accessories to be tested: Damon Q, Damon Clear (Ormco), In-Ovation R, In-Ovation C (GAC), BioQuick, QuickClear (Forestadent), SmartClip and Clarity SL (3M). Data were subjected to One-way ANOVA, followed by Tukey tests (P<0.05). Re…
Altered processing of sensory stimuli in patients with migraine.
2014
Migraine is a cyclic disorder, in which functional and morphological brain changes fluctuate over time, culminating periodically in an attack. In the migrainous brain, temporal processing of external stimuli and sequential recruitment of neuronal networks are often dysfunctional. These changes reflect complex CNS dysfunction patterns. Assessment of multimodal evoked potentials and nociceptive reflex responses can reveal altered patterns of the brain's electrophysiological activity, thereby aiding our understanding of the pathophysiology of migraine. In this Review, we summarize the most important findings on temporal processing of evoked and reflex responses in migraine. Considering these d…
Creatividad en alumnos de talento matemático
2019
En el presente trabajo hacemos un estudio exploratorio en el que pretendemos medir la creatividad en relación con el talento matemático, basándonos en los trabajos de Roza Leikin (con su permiso). Seleccionamos dos muestras de alumnos, una formada por estudiantes de entre 15 y 17 años participantes en el programa ESTALMAT (dirigido a estudiantes con talento matemático), y la otra formada por alumnos del máster, con una sólida formación matemática. A cada participante, le pasamos un test con 4 problemas de matemáticas que son tareas de resolución múltiple, y les pedimos que den tantas soluciones como puedan de cada uno en un cierto límite de tiempo. Después, analizamos los resultados, tanto …
Fazer pós-graduação em educação em ciências melhora o ensino?
2018
espanolEn este articulo se indaga como influye el transito por dos maestrias en educacion en ciencias y tecnologia de Cordoba y La Plata (Argentina) en el desempenode docentes cursantes a las mismas. Nuestra hipotesis fue que dicho transito debia mejorar sus practicas y sus habilidades de investigacion. Para tal fin se hicieron preguntas a estos docentes, relacionadas con sus practicas y con los cambios que pueden haber sido promovidos por dichos estudios de posgrado. Ello se complemento con observaciones a sus clases. Los resultados muestran que la maestria genero modificaciones en la practica docente, que desarrollo o perfecciono sus habilidades de investigacion educativa y que la partici…
MEDIA SKILLS AND PROFESSIONAL AWARENESS IN TEACHER TRAINING
2016
The present paper documents the use of an e-portfolio to promote a process of reflection on the digital skills of in-service teachers. Teachers have been involved for 75 hours in experiencing a training methodology for the promotion of media skills necessary to design paths of media education. The use of the e-portfolio as a means of course assessment was evaluated by the participating group of 91 trainee teachers. The methods of data collection took the form of an analysis carried out thanks to the use of a check list with 22 indicators deduced from the research, of which the frequency was observed. The analysis of the e-portfolios revealed a high trainee teachers’ ability to recognize the…
Introducing Dialogic Teaching to Science Student Teachers
2011
It is commonly believed that science teachers rely on language that allows only minor flexibility when it comes to taking into account contrasting views and pupil thoughts. Too frequently science teachers either pose questions that target predefined answers or simply lecture through lessons, a major concern from a sociocultural perspective. This study reports the experiences of science student teachers when introduced to the Communicative Approach to science education drawing on dialogic teacher-talk in addition to authoritative teacher-talk. This approach was introduced to the students in an interventional teaching program running parallel to the student teachers’ field practice. The pract…
The influence of age-based faultlines on team performance: Examining mediational paths
2021
Abstract In a sample of 60 branches of a bank, we examine the influence of age-based faultlines on team performance. Specifically, we propose a model with four mediational paths in the age-based faultline-team performance link. Using a time-lagged design with three data-collection points, we found that task conflict, team reflexivity, and negative team mood mediated the negative relationship between age-based faultline strength and team performance. The results reveal the value of examining different mediational paths to explain the negative impact of teams’ demographic faultlines on team performance, and the need to integrate both task-related and affective aspects of team work in order to…
Experiments on Longitudinal and Transverse Bedload Transport in Sine-Generated Meandering Channels
2021
Bedload grains in consecutive meandering bends either move longitudinally or across the channel centerline. This study traces and quantifies the grains’ movement in two laboratorial sine-generated channels, i.e., one with deflection angle θ0 = 30° and the other 110°. The grains originally paved along the channels are uniform in size with D = 1 mm and are dyed in various colors, according to their initial location. The experiments recorded the changes in the flow patterns, bed deformation, and the gain-loss distribution of the colored grains in the pool-bar complexes. We observed the formation of two types of erosion zones during the process of the bed deformation, i.e., Zone 1 in the foresi…
Demand Response Service Certification and Customer Baseline Evaluation Using Blockchain Technology
2020
The use of Distributed Ledger Technologies such as Blockchain for certifying Demand Response services allows for the creation of a distributed system in which customers can communicate with the system operator to provide their flexibility, in a secure, transparent and traceable way. Blockchain technology also supports incentive mechanisms for users taking part in the service through the generation of utility tokens to recognize the user's contribution. This paper presents the experimental test of a novel methodology for Demand Response programs implementation by using the Blockchain technology. The latter is employed for defining a distributed Demand Response service and a new system for it…
