The research is based on the understanding that mathematical knowledge is not present only in the school environment, but also in the everyday practices of different social groups, especially those who build their knowledge through experience, social interaction, and work-related needs. The study is grounded in the perspective of Ethnomathematics and values the knowledge produced within the cultural context of artisanal fishermen. The researcch is characterized as qualitative and exploratory, conducted through interviews with three artisanal fishermen from the municipality of Baía da Traição-PB. The participants’ statements revealed that, even with limited formal schooling, they mobilize mathematical knowledge in several fishing-related situations, such as the use of measurements of length, capacity, and mass, as well as calculatchionns involving division, proportion, estimation, and percentage. These forms of knowledge appear in the organization of fishing activities, in boat preparation, in the division of the catch, in the making of fishing nets, and in the use of traditional measurement units, such as the handspan and the fathom. The results show that the mathematical knowledge present in artisanal fishing is constructed through practice, transmitted across generations, and closely connected to the culture and lived reality of the fishermmen Editor: Universidade Federal da Paraíba Tipo: TCC 2026-03-30T00:00:00Z https://repositorio.ufpb.br/jspui/handle/123456789/38226 Título: A Heurística de Polya no ensino de sistemas lineares: um estudo de caso em uma escola pública do município de Itapororoca-PB Autor(es): Paulo, Kianny Yris Santos de Orientador: Santana, Agnes Liliane Lima Soares de Abstract: This study analyzed the application of George Polya's heuristic in solving problems involving linear systems in high school, in two 2nd-year classes at a public school in the city of Itapororoca. The objective was to investigate whether the use of this approach would contribute to minimizing difficulties related to the interpretation of statements and the development of problem-solving strategies. A quantitative-qualitative methodology was adopted, based on the application of activities with two classes: one that received guidance on Polya's heuristic and another that did not have access to this strategy. The proposal was based on the four stages of the method: comprehension, plan establishment, plan execution, and reflection, applied to solving problems with linear systems. The research also relied on the guidelines of the National Common Curriculum Base, especially regarding the development of skills related to problemsolving. The results showed that the students who used the heuristic performed better in interpreting the statements and organizing problem-solving strategies, compared to the class that did not receive guidance. It was also observed that the students' initial difficulty was strongly associated with understanding the problems, which was partially overcome with the systematic application of the steps proposed by Polya. It was concluded that the use of Polya's heuristic significantly contributed to making the learning of linear systems more accessible, favoring the development of mathematical thinking and bringing the discipline closer to the students' reality.

Para alcanzar este objetivo, se establecieron tres objetivos específicos: explorar estrategias y metodologías inclusivas ya utilizadas en la enseñanza de Geometría adaptadas para estudiantes sordos; ejecutar una secuencia didáctica para la enseñanza de conceptos de Geometría a alumnos sordos de la EJA; y analizar la secuencia didáctica aplicada a la luz del debate realizado con la comunidad científica y referencias teóricas contemporáneas. La justificación de esta investigación surge de la urgencia de desarrollar prácticas pedagógicas inclusivas que atiendan adecuadamente a los estudiantes sordos en la enseñanza de Matemáticas, dado que solo el 7% de las personas sordas en Brasil poseen educación superior completa. Metodológicamente, la investigación se caracteriza como básica en cuanto a su naturaleza; cualitativa en cuanto al enfoque; exploratoria en cuanto a los objetivos; y en cuanto a los procedimientos, se trata de un estudio de caso combinado con una revisión bibliográfica, en la cual se consultaron 37 obras de 34 autores, datadas entre 1893 y 2026, proporcionando una base teórica sobre la enseñanza para sordos, aplicaciones, adaptación de materiales y Educación Matemática. Los instrumentos de recolección de datos incluyeron entrevistas con gestores, profesores e intérpretes a través de preguntas abiertas para identificar el perfil de los alumnos sordos, la disponibilidad de ambientes apropiados; observación durante las clases con registro de los comportamientos, interacciones y aprendizajes de los estudiantes durante la aplicación de la secuencia didáctica. La secuencia didáctica fue aplicada en tres clases en el ambiente de Atención Educativa Especializada, para dos estudiantes sordos con mediación de un intérprete de Libras, siendo los hallazgos parciales compartidos con la comunidad científica a través de la presentación a un congreso internacional, al portal educativo de la Capes y a un evento de extensión de la UFPB de Libras para sordos. Los resultados encontrados indican que los estudiantes lograron una comprensión satisfactoria de los conceptos de Geometría trabajados. Como sugerencias para futuras investigaciones, la comunidad científica recomendó extender la presente investigación a nivel de maestría/doctorado con fines de mayores seguimientos longitudinales. La relevancia de esta investigación se manifiesta en la dirección de la justicia educativa, ya que las personas sordas y el público de la Educación de Jóvenes y Adultos son, históricamente, víctimas de la falta de acceso al conocimiento escolar. De esta forma, es de interés académico fomentar el debate sobre metodologías inclusivas en la enseñanza de Geometría para un público históricamente vulnerable.

The study was based on Mathematics Education in a contextualized perspective, articulated with the valorization of everyday knowledge and the relationship between school and social reality, considering Mathematics as knowledge present in social and professional practices. The research was characterized as qualitative, exploratory in nature, being carried out in the context of the field activities of the Agents to Combat Endemic, with the participation of professionals working in the health surveillance of the municipality. Data were collected through observation of the activities developed in the territory, records of practices related to LIRAa, the use of ovitraps, vector control and larvicide application, as well as descriptive notes on the planning of home visits, organization of routes and analysis of epidemiological indices. The data analysis was developed in an interpretative way, seeking to identify situations in which mathematical concepts were mobilized in professional actions, such as counting properties, estimations, proportionality, calculating dosages, interpreting tables, reading graphs, spatial organization of the territory and analysis of infestation percentages. The results showed that the agents used, in a continuous and functional way, various mathematical knowledge in the planning and execution of their activities, although they often do not explicitly recognize these actions as mathematical practices. It was observed that Mathematics manifested itself in a concrete way in the organization of work, in decisionmaking in the field, in the analysis of epidemiological data and in the definition of strategies to control endemics, demonstrating a strong relationship between mathematical knowledge and social reality. It was also found that the professional practices of the agents presented a significant approximation with the mathematical contents worked in High School, especially in the fields of Numbers, Quantities and Measures and Statistics, which reinforced the pedagogical potential of the daily life of these professionals for the contextualization of teaching. It was concluded that the work of the Agents to Combat Endemic Diseases constitutes a legitimate space for the mobilization of mathematical knowledge and that the valorization of these practices can contribute to a more meaningful, contextualized and socially relevant Mathematics Education, by bringing school knowledge closer to the concrete experiences lived in the Community.
