Educação Inclusiva: perfil e formação inicial de estagiários que auxiliam estudantes da Educação Especial

The aim of this study was to analyze the profile of trainees who work with special education students, focusing on the training they received from a public school system to support this public. The research was carried out with undergraduates from a public state university, using document analysis was carried out and an online questionnaire was administered to 67 undergraduate students. The results indicated a low number of subjects related to Special Education from the perspective of Inclusive Education during initial training, insufficient training, as well as a need for knowledge about resources that can be used in daily school activities, more specific guidance on the trainee's role in the school environment and on their duties and rights. It is considered that the internship plays a fundamental role in professional and personal development, providing an opportunity to apply the theoretical knowledge acquired, in a real work environment, which can stimulate reflections on Inclusive Education, providing students with humanized professional support. El objetivo de este estudio fue analizar el perfil de los aprendices que trabajan con alumnos de educación especial, centrándose en la formación que recibieron de un sistema público de enseñanza de apoyo a este público. La investigación se llevó a cabo con estudiantes de pregrado de una universidad estatal, analizando documentos y aplicando un cuestionario en línea a 67 estudiantes de pregrado. Los resultados indicaron un bajo número de asignaturas relacionadas con la Educación Especial desde la perspectiva de la Educación Inclusiva durante la formación inicial, una formación insuficiente, la necesidad de conocimientos sobre los recursos que se pueden utilizar en las actividades escolares diarias, orientaciones específicas sobre el papel del alumno en el entorno escolar y sobre sus deberes y derechos.

Aplicação Prática das Heurísticas de Nielsen na Avaliação de um Sistema de Análise da Não Conformidade de Softwares com a LGPD

ABSTRACTIn recent years, technological advancements have markedly intensifiedthe collection, processing, and storage of personal data, makingit essential for current systems to conform to Brazil’s General DataProtection Law (Lei Geral de Proteção de Dados — LGPD) to ensurelegal compliance and effectively safeguard user privacy. This paperexplores the practical application of Nielsen’s usability heuristics inevaluating the Adequa 2.0 system, a tool developed to identify softwareproducts’ non-compliance with the LGPD. Adequa 2.0 seeksto automate the assessment process through a dynamic questionnairethat fosters effective and intuitive user interaction. Usabilitywas measured using Nielsen’s 10 heuristics. Tests were carried outwith students in the technical Informatics program at the FederalCenter for Technological Education of Minas Gerais (CEFET-MG),Leopoldina campus, who used the tool to evaluate their projects’compliance with the LGPD. The findings underscore the importanceof uniting regulatory requirements with best practices in interfacedesign to ensure LGPD conformity without compromising userexperience

Análise de Escalabilidade para Armazenamento e Processamento de Arquivos de Áudio Utilizando Transformers

ABSTRACTIn a continental-sized country like Brazil, collecting feedback ongovernmental services such as education, healthcare, and securityis challenging and impractical to perform manually, exceptthrough sampling techniques. With advancements in machine learning,particularly models based on transformers, it is now possibleto automate this process on a large scale, enabling, for instance,the dissemination of health campaign information or the collectionof citizen opinions on recently used services. This paper focuseson speech-to-text transcription, a crucial step for enabling largescalevoice-based responses.We explored scalability challenges andevaluated combinations of transcription models and audio formats(WAV, FLAC, and MP3), aiming to balance the computational costand transcription quality. Our results showed that MP3 files sampledat 14 kHz provide transcription quality comparable to WAVfiles sampled at 16 kHz while requiring only 11% of the storagesize. Furthermore, we demonstrated that smaller models, such asWav2Vec2-XLSR-53 with 3.17 × 108 parameters, can achieve resultssimilar to larger models, such as Seamless M4T, which hasapproximately an order of magnitude more parameters

Reconhecimento de Voz Aplicado ao Jogo de Xadrez Usando a Plataforma Arduino

AbstractChess is a strategic game that enhances cognitive skills, yet itsphysical demands can exclude players with motor disabilities. Thisstudy presents a voice recognition system that enables chess piecemovement through verbal commands, enhancing accessibility. Theproposed solution integrates the VoiceRecognitionV3 module withthe Arduino Uno to recognize spoken commands related to gameactions. The methodology involves training the system to interpreta structured set of voice commands, organizing the chessboard intoquadrants for efficient processing. Initial tests confirm the feasibilityof voice-controlled chess interactions, demonstrating potentialbenefits for accessibility. However, limitations include the module’sconstraint of recognizing only seven commands simultaneously andthe necessity for user-specific voice training. Future improvementsmay involve integrating advanced speech recognition algorithmsand machine learning to expand command recognition and adaptability.This research highlights the potential of voice recognition ininteractive and inclusive gaming environments

FlipUFSC Estratégia de Gamificação como Alternativa Pedagógica para o Período Pré-vestibular

ABSTRACTThe Federal University of Santa Catarina’s entrance exam is the primary means of admission to the institution. This period often induces anxiety, fear, insecurity, and distress among students. Reflecting on the potential of teaching methodologies to ensure the necessary competencies and mitigate tensions during exam preparation, the inclusion of digital games in education has proven to be a positive approach. This work presents the development process of the educational game FlipUFSC — modeled after an arcade game and employing the Design Science Research Methodology (DSRM) — which integrates questions sourced from UFSC’s entrance exams. Thus, it aims to contribute to ensuring inclusive, equitable, and quality education, as established in Goal 4 (Quality Education) of the United Nations Sustainable Development Goals (SDGs), by making this preparatory period more engaging in order to support access to higher education
