    O processo de construção do conhecimento geométrico de estudantes do ensino médio com o GeoGebra
    (Universidade Federal de Catalão, 2023-08-30) Paiva, Fabricio Berigo de; Borges, Marta; http://lattes.cnpq.br/6407324517825514; Borges, Marta; http://lattes.cnpq.br/6407324517825514; Barbosa, Fernando da Costa; Barros, Ana Paula Paula Rodrigues Magalhães de
    The research aims to use digital technologies in teaching Mathematics with GeoGebra in High School. The research had a qualitative and participatory approach and was developed as a Training Itinerary in the Geometric Constructions in Everyday Life elective, with the aim of identifying Constructionist actions in the construction of geometric knowledge to reflect on student productions in activities developed with GeoGebra in an elective class. composed of students from the 1st and 2nd years of high school, in which some student constructions selected by the researcher were analyzed, aiming to answer the following question: How did GeoGebra contribute to the process of building students' knowledge? Based on Constructionism, created by Papert, as the student builds their knowledge using means that stimulate them and that hold meaning. Valente, a precursor of Constructionism who created the learning cycle that later gave rise to the learning spiral, highlights the importance of the student “getting their hands dirty” in which, through experimenting with their autonomy and creativity, they will discover concepts and conjectures. It was developed based on participant observation in three moments: First moment: presentation of the GeoGebra website and community, in addition to the procedures necessary to install the program on computers and cell phones. Second moment: presentation of its basic functionalities and activities were carried out with basic geometric constructions in order to teach students how to manipulate the program and remember geometry concepts. Third moment: application of an activity related to everyday life with the creation of a roof with a rectangular slab. The research was developed in five meetings with double classes. The concepts of midpoint, perpendicular bisector, median, triangle congruence and similarity, ratio and proportion were worked on, as well as the theorems of Thales and Pythagoras. The data was produced through photos, notes and at the end of the meetings, recording the narration of the activities and dialogues that took place in the laboratory and production of activities with GeoGebra. After talking about the construction of some students, it was possible to verify that the movement of the construction in this environment makes the students verify the conservation of important geometric properties, starting, from experimentation, to question themselves about the properties, to formalize conjectures. capable of verification and to plan, with solid arguments, the solution of problems.

    Lógica Fuzzy aplicada ao gerenciamento de redes definidas por software
    (Universidade Federal de Catalão, 2023-10-03) Ribeiro Júnior, Jaime; Costa, Vaston Gonçalves da; http://lattes.cnpq.br/5192533875584788; Costa, Vaston Gonçalves da; http://lattes.cnpq.br/5192533875584788; Stoppa, Marcelo Henrique; Gonçalves, Anderson Cavalcante
    This paper presents the results of a research study that utilizes Fuzzy Logic to investigate the equitable allocation of bandwidth in networks, considering various user profiles. Fuzzy Logic offers flexibility in bandwidth distribution, taking into account Fuzzy variables such as bandwidth requirements, traffic priorities, and usage patterns. The goal is to develop applications for Software-Defined Networks (SDNs) that incorporate Fuzzy Logic, thereby enhancing the efficiency of network resource allocation in complex environments. This research is motivated by the growing need for network management automation, driven by the rise of the Internet of Things (IoT) and the demand for connectivity. SDNs offer a promising approach to this automation, allowing for the separation of the logical and physical network planes and the integration of intelligent applications. Efficient bandwidth allocation is critical for optimizing network performance and user satisfaction, making this research field significant. In addition to cataloging SDN technologies, conducting a literature review on AI with an emphasis on Fuzzy Logic, and developing intelligent algorithms, this paper also presents results from a prototype implemented in Python. The analysis of these results evaluated the equity and quality of bandwidth allocations. This work contributes to the fields of SDNs and AI, highlighting how Fuzzy Logic can enhance bandwidth distribution in computer networks. Automation and efficient resource allocation are crucial to meet the demands of modern networks, and this research advances toward intelligent solutions.

    Avaliação da influência do uso de embeddings no reconhecimento de entidades nomeadas para o português
    (Universidade Federal de Catalão, 2023-08-31) Gomes Junior, Carlos Silvio; Silva, Nádia Félix Felipe da; http://lattes.cnpq.br/7864834001694765; Silva, Nádia Félix Felipe da; http://lattes.cnpq.br/7864834001694765; Moura Júnior, José dos Reis Vieira de; Cordeiro, Douglas
    Named Entity Recognition (NER) is a crucial task in today's context, as there is an increasing demand for automated tools capable of extracting information from texts. Although NER is a widely studied area, it remains complex and requires a high cost in terms of time and computational resources, especially in languages with few resources, such as Portuguese, which lacks annotated data and high- performance trained models. In order to contribute to the development of this task in Portuguese language, this work applied the Deep Learning (DL) architecture, BiLSTM-CRF, using the FlairNLP Framework, testing different types of Word Embeddings, Static Embeddings, Contextualize Embeddings, and their concatenations, to analyze their influence on the results obtained. The trained models showed a significant gain in the use of Contextualize Embeddings and Embeddings concatenation, achieving a new state of the art with an F1 score of 98.88% for the general domain in the MultiWikiNER multilingual corpus, in the legal domain 89.31% for the LeNER-Br Corpus and 86.86% for the Pl-Corpus, which is part of the UlyssesNER-Br.

    O social nas práticas escolares: o letramento e o ensino de história na educação de jovens e adultos (EJA) em Paracatu – MG (2012 – 2022)
    (Universidade Federal de Catalão, 2023-09-04) Fernandes, Wanderlândia Silva Neiva; Carmo, Luiz Carlos do; Carmo, Luiz Carlos do; Carmo, Maria Andréa Angelotti; Silva, Jeanne; Inácio Paulo César; Abreu, Jean Luiz Neves
    This master's dissertation analyzes the dynamics of social functioning in school practices and the teaching of History, with the main objective of understanding how they can contribute to the consolidation of literacy and reading skills of young and adult students in Elementary Education - Final Years of the Youth and Adult Education (EJA). To do so, it examines the historical and social trajectory of a group of students, combined with the implementation of EJA programs in Brazil. This study also relies on the investigation of federal and state educational resolutions and legislation related to the literacy of young adults. A specific research focus was carried out at the Cacilda Caetano de Souza Municipal School, located in Paracatu-MG. The research timeframe covered the period from 2012 to 2022, during which part of the formative efforts of a group of EJA students from the aforementioned school was observed. In terms of methodology, the strategy involved analyzing how a group of students and former students consider important aspects of their experiences. To generate data, the researcher adopted the technique of a focus group and the application of questionnaires. The questionnaires were administered by the responsible researcher to obtain insights into how the participants perceive and process their personal and collective trajectories. The questionnaire data were tabulated and analyzed, with the responses treated using graphs to construct the profile of EJA in the municipality of Paracatu- MG. During History classes, which were used as a focus group and a stimulus for learning, an enhanced performance was observed, facilitated by workshop classes and pedagogical intervention activities. The results underscore the significance of the History teacher in today's society, as a transformative agent through their pedagogical work in the classroom. Additionally, they point to a continuous political advocacy to materialize laws at the school level, emphasizing the crucial role of idealistic teachers, researchers, and facilitators of the teaching and learning process.

    A pedagogia da violência e da obediência aplicadas: a militarização do Colégio José Pio De Santana em Ipameri-GO entre os anos de 2017 e 2019
    (Universidade Federal de Catalão, 2023-10-03) Freitas , Maíra Aparecida Brandão de; Inácio, Paulo Cesar; http://lattes.cnpq.br/7919002505765437; Inácio, Paulo Cesar; http://lattes.cnpq.br/7919002505765437; Silva, Jeanne; Carmo, Maria Andréa Angelotti
    This research dealt with a study about the implementation process of the State College of the Military Police of the State of Goiás-CEPMG José Pio de Santana in the city of Ipameri-GO, therefore, it aims to seek understanding about its implementation and its implications and transformations that occurred in the organization of pedagogical work with a time frame from 2017 to 2019. In this sense, an attempt was made to understand the questions contained about the implementation of this model of public education, interpreting the meanings that these changes had in the lives of those involved, students, family members, teachers, school management, about the transition period from the school to militarization and how this new model can shape the education and teaching of students. We identified that effective militarization is an apparatus that privileges the use of instruments that value fear, violence, hierarchy and obedience, as instruments that not only allow the pedagogical relationship, but also implement an applied pedagogy. In the research we interpreted interviews produced with teachers, family members. In interpreting the interviews, we approached authors such as Alessandro Portelli and Miguel Arroyo. To carry out this work, it was used as an oral source, through interviews with students' parents, teachers, the school's management group, and bibliographical analysis of some authors. Adhering also to the study of oral history whose intention was to appeal to people who participated or witnessed the fact.
