Recognition of EEG Signals from Imagined Vowels Using Deep Learning Methods

The use of imagined speech with electroencephalographic (EEG) signals is a promising field of brain-computer interfaces (BCI) that seeks communication between areas of the cerebral cortex related to language and devices or machines. However, the complexity of this brain process makes the analysis and classification of this type of signals a relevant topic of research. The goals of this study were: to develop a new algorithm based on Deep Learning (DL), referred to as CNNeeg1-1, to recognize EEG signals in imagined vowel tasks; to create an imagined speech database with 50 subjects specialized in imagined vowels from the Spanish language (/a/,/e/,/i/,/o/,/u/); and to contrast the performance of the CNNeeg1-1 algorithm with the DL Shallow CNN and EEGNet benchmark algorithms using an open access database (BD1) and the newly developed database (BD2). In this study, a mixed variance analysis of variance was conducted to assess the intra-subject and inter-subject training of the proposed algorithms. The results show that for intra-subject training analysis, the best performance among the Shallow CNN, EEGNet, and CNNeeg1-1 methods in classifying imagined vowels (/a/,/e/,/i/,/o/,/u/) was exhibited by CNNeeg1-1, with an accuracy of 65.62% for BD1 database and 85.66% for BD2 database.

Digital educational environment as a factor of developing teacher’s professional reflection

The article explores the problem of teachers’ reflexivity, its influence on the educational process and the specifics of teachers’ professional activity. The research purpose is a theoretical and empirical study of teachers’ reflexivity and its developmental specifics. The main forms of reflexivity development are lecturing, training, analysis, self-analysis and testing. To improve the personality traits which are important for reflexivity development (self-awareness, communication skills, empathy, identification of professional and personal value guidelines, etc.), a teacher may also use different games and tasks, along with various methods of analyzing the lessons and his/her own contribution to them. All these resources should be included in the annual plan of an educational organization. The results of the study allow concluding about the effectiveness of the declared measures for teachers’ reflexivity development. Within the changing domestic education system, one of the key challenges is training teachers who meet the requirements of the modern professional standard. A possible solution to this problem can be systematic work in an educational organization to improve the teacher’s underdeveloped qualities. One of these characteristics, which can influence the improvement of the teacher’s professionalism and ensure the compliance with the professional standard, is reflexivity. Along with the fact that reflexivity is among the most important components of the pedagogical activity, it is necessary to recognize the poor criterial basis for the professional reflexivity of teachers working in educational organizations, namely the applied aspects of its development within teachers’ methodological activity.

En el ámbito del entrenamiento deportivo la estructuración pedagógica de las tareas comprende un importante eje de investigación, ya que constituye una práctica básica en el desempeño del entrenador deportivo. El objetivo de este estudio fue analizar la estructura pedagógica de las tareas de entrenamiento técnico-táctico en categorías en formación de balonmano. El diseño del presente estudio se encuadra dentro de la investigación descriptiva, cuantitativa y observacional, con 27 atletas y dos entrenadores, de dos equipos de balonmano femeninos de la categoría sub-16 del estado de Santa Catarina. La recopilación de datos se basó en la observación indirecta y sistemática de 36 sesiones de formación, que fueron transcritas en el Sistema Integral para el Análisis de las Tareas de Entrenamiento (SIATE) y analizadas a partir de estadísticas descriptivas e inferenciales. Los resultados obtenidos demuestran que, aunque los entrenadores tienen años de experiencia distintos en la modalidad de balonmano, el proceso de entrenamiento y el desarrollo de las tareas de entrenamiento fue similar, y ambos entrenadores buscan aplicar situaciones técnicas y tácticas simultáneas en las sesiones de entrenamiento. La investigación sugiere la posibilidad de mapear las tareas de entrenamiento, lo que permite a estos profesionales desarrollar una perspectiva más clara y detallada de la estructuración técnico-táctica del proceso. === In the field of sports training, the pedagogical structuring of tasks includes an important research axis, since it constitutes a basic practice in the performance of the sports coach.

THE SPECIFICS OF A DANCE TEACHER’S WORK IN THE CRISIS OF 2020

The 2020 has been a year of many challenges in many professions and also for dance teachers. The daily challenge is to replace existing dance classes with a totally different class structure, which is defined by the governmental restrictions. The dance teachers must react to these restrictions immediately and without any methodological materials and support. In the crisis the dance teachers must use such learning organizational forms as: group, individual and online, and use them as alternatives to one another. Can a dance teacher reach their professional (curriculum) goals by alternating components of the study process? How do the changing circumstances affect dancers and their attendance? The aim of this article is to analyse the possibilities of a dance teacher to reach their professional goals with group, individual and online classes and to determine the dancers satisfaction with these classes. The research is realized in terms of one dance studio and in two stages. The first stage (March-July 2020) were an experimental video-instruction independent training analysis. 40 video materials were grouped in 20 classes and sent to 20 dancers. The second stage (September-January 2020) were group, individual and online class analysis from the teacher’s and dancers perspective.
