Edma 0-6 : educación matemática en la infancia
2018
There are numerous studies that support the interest of starting the development of algebraic thinking in Primary School. In this paper, we present a part of a research project aimed to explore the processes of solution of geometric pattern problems by students in Primary grades 4th to 6th. We analyze the behavior of students who were administered a teaching unit based on the resolution of this type of problems in the GeoPattern application, created by the authors for this purpose. A characteristic of the application is that it informs the students on the correctness of their answers and allows them to respond again to the same question when their answer was wrong. This causes the students …
Adolescents' postural control learning according to the frequency of knowledge of process
2019
Feedback is one of the most influential factors for motor skills learning. Physical Education teachers commonly use verbal cues to provide knowledge of process (KP) when teaching motor skills, but the ideal presentation frequency for KP in adolescents is unclear. The aim of this study was to compare the effectiveness of the frequency of KP (i.e., 100%, 67%, 0%) on dynamic balance. Thirty adolescents, age 14–15 years, participated in the study. Performance on a stabilometer platform was used to assess dynamic balance. Participants received feedback after each trial (100%), in two out of three trials (67%), or no feedback during 12 30-s trials of practice. Adolescents who received feedback (6…
La evaluación del aprendizaje: de la retroalimentación a la autorregulación. El papel de las tecnologías.
2015
Este artículo recoge una revisión sobre la evaluación en el ámbito universitario focalizada sobre la información que se aporta a los estudiantes a partir del análisis de sus resultados de aprendizaje. Para ello, define conceptos como retroalimentación, proalimentación y autorregulación del aprendizaje y los sitúa dentro del proceso de evaluación. Tras segmentar dicho proceso en sus componentes fundamentales, este trabajo se detiene en la relación entre el modo en que se aporta información sobre la evaluación (con especial atención al papel de las TIC) y la forma en que dicha información se utiliza por parte de los estudiantes, considerando variables que afectan a sus antecedentes académicos…
Infralow neurofeedback in the treatment of substance use disorders: a randomized controlled trial
2022
Background Infralow neurofeedback (ILF-NF) was recently developed as a subtype of traditional, frequency-based neurofeedback that targets cerebral rhythmic activity below 0.5 Hz and improves brain self-regulation. The efficacy of ILF-NF in the treatment of substance use disorder has not yet been evaluated, but clinical evidence suggests that it may prevent relapse by improving functioning in various life domains. The current study aimed to fill this research gap and extend empirical evidence related to this issue. Methods Ninety-three patients with substance use disorders at an outpatient unit in Norway were randomized to receive 20 sessions (30 minutes each) of ILF-NF training combined wit…
Manipulating feedback on schizophrenia: Evidence from a Posner task.
2021
Abstract Individuals with schizophrenia show difficulties in achieving vital objectives. Abnormal behavioral and emotional responses to environmental feedback may be some of the psychological mechanisms underlying this lack of goal attainment in schizophrenia. The present study aims to assess how different types of feedback may affect performance in a computerized affective Posner task (non-monetary vs. monetary rewards; contingent vs. non-contingent feedback). The sample was composed of 32 patients with schizophrenia and 35 controls. Reaction times and error rates were the behavioral measurements. The emotional experience was assessed through self-reported affective scales. The results ind…
Trajectory robust control of autonomous quadcopters based on model decoupling and disturbance estimation
2021
In this article, a systematic procedure is given for determining a robust motion control law for autonomous quadcopters, starting from an input–output linearizable model. In particular, the suggested technique can be considered as a robust feedback linearization (FL), where the nonlinear state-feedback terms, which contain the aerodynamic forces and moments and other unknown disturbances, are estimated online by means of extended state observers. Therefore, the control system is made robust against unmodelled dynamics and endogenous as well as exogenous disturbances. The desired closed-loop dynamics is obtained by means of pole assignment. To have a feasible control action, that is, the fo…
Intermittent decoherence blockade in a chiral ring environment
2021
It has long been recognized that emission of radiation from atoms is not an intrinsic property of individual atoms themselves, but it is largely affected by the characteristics of the photonic environment and by the collective interaction among the atoms. A general belief is that preventing full decay and/or decoherence requires the existence of dark states, i.e., dressed light-atom states that do not decay despite the dissipative environment. Here, we show that, contrary to such a common wisdom, decoherence suppression can be intermittently achieved on a limited time scale, without the need for any dark state, when the atom is coupled to a chiral ring environment, leading to a highly non-e…
Effects of Timing and Level of Integration of Formative Feedback in Question-Answering for Concept Learning
2019
De acuerdo con la literatura previa dentro del contexto de la retroalimentación formativa (Bangert-Downs et al., 2013; Butler & Roediger, 2008; Butler & Winne, 1995; Hattie & Timperley, 2007; Kapp et al., 2015; Karpicke, & Roediger, 2007, 2008; Llorens, et al., 2014; Máñez, Vidal-Abarca & Martínez, 2016; Máñez, Vidal-Abarca, Martínez & Kendeu, 2017; Newman, Williams & Hiller, 1974; Narciss, 2013; Narciss et al., 2014 ; van der Kleij, Eggen, Timmers, & Veldkamp, 2012; van der Kleij, et al., 2015; Vidal-Abarca et al., 2017; Vidal-Abarca, Martínez, Ferrer & García, 2017), el objetivo general de la presente tesis es la evaluación de la efectividad de un procedimiento formativo de lectura y cont…
Antagonistic feedback loops involving Rau and Sprouty in the Drosophila eye control neuronal and glial differentiation.
2013
During development, differentiation is often initiated by the activation of different receptor tyrosine kinases (RTKs), which results in the tightly regulated activation of cytoplasmic signaling cascades. In the differentiation of neurons and glia in the developing Drosophila eye, we found that the proper intensity of RTK signaling downstream of fibroblast growth factor receptor (FGFR) or epidermal growth factor receptor required two mutually antagonistic feedback loops. We identified a positive feedback loop mediated by the Ras association (RA) domain-containing protein Rau that sustained Ras activity and counteracted the negative feedback loop mediated by Sprouty. Rau has two RA domains t…
Dataset of a globally relevant stock of soil nitrogen in the Yedoma permafrost domain
