Introduction: Cerebral palsy (CP) encompasses permanent disorders of movement and posture, attributed to non-progressive brain injury occurring in the fetal or infant brain, resulting in significant functional limitations. Objective: To investigate the influence of the environment on the manual performance of 14 children with CP, aged 1 to 4 years, using the Mini-MACS in clinical and home contexts. Materials and Methods: The study was publicized in clinics located in Jundiaí and São Carlos. Fourteen children participated; after obtaining parental consent, they were filmed in a clinical setting performing manual activities to be classified using the Mini-MACS. Subsequently, the researcher interviewed the caregivers about the child’s manual performance and requested that the same activities be carried out at home. The videos were independently analyzed by two researchers for Mini-MACS classification. The qualitative assessment was conducted by researcher 1 and the caregivers. Data were organized in tables to facilitate interpretation. Results: The Mini-MACS classification remained stable across environments, confirming its reliability. However, the qualitative analysis revealed differences: some children demonstrated greater spontaneity and functionality at home, while others performed better in the clinical setting, benefiting from therapeutic stimuli. Conclusion: Assessments that integrate quantitative and qualitative data are essential to understanding child functionality and to planning interventions centered on the child, the family, and the context.

This study arises from the concerns, knowledge exchanges, and questions experienced within the Quilombo Cafundó community, located in Salto de Pirapora (SP), Brazil. The case study was developed from the extension project “Roots and Resistances,” focused on adult literacy, which has been active since 2017. The main objective of this research is to analyze how the absence of a school in the Quilombo Cafundó territory and the limited access to quilombola school education impact the life trajectories of quilombola residents, in dialogue with the knowledge exchanges between a teacher/researcher and community members. This qualitative study was guided by Stake’s (1995) case study methodology and oral life history interviews (Meihy; Holanda, 2023), emphasizing the memories and narratives of residents. The interviews focused on access to education and the possibilities of continuing and completing basic education. Notably, the community lacks a quilombola school, and students attend nearby schools. The study is grounded in the reflections of Antonio Bispo dos Santos (Nêgo Bispo) (2015, 2018, 2023), translator and recorder of quilombola knowledge, and his concept of counter-colonization. The research frames education as a space for knowledge sharing and confluence, reaffirming ancestral practices and quilombola ways of learning and teaching. The study further examines how quilombola school education, as recommended by the National Curriculum Guidelines for Quilombola School Education in Basic Education (2012), is being implemented, or not, in the Cafundó community. Findings contribute to expanding research on quilombola education and strengthening public policies that recognize the knowledge, historical, and social relevance of quilombos.

This project modeled and optimized a prototype of a fuzzy temperature controller for use in microalgae cultivation in a photobioreactor, employing Simulated Annealing for controller tuning and optimization of the fuzzy defuzzification equations. The prototype consisted of a thermal bath with two temperature sensors, a vessel with electric heating, a cooling water vessel, a water pump, a solenoid valve, and the use of an open-source prototyping platform in C++ (Arduino), LabVIEW for thermal control supervision, and MATLAB for system modeling and optimization. The fuzzy controller was developed using temperature membership functions: Very Low, Low, Optimal, High, and Very High. These parameters were incorporated into the manipulation of electrical heating power, associated with adjustable constants, so that the optimizer could tune the controller to maintain the photobioreactor temperature as close as possible to the desired value. For cooling, the membership functions were also incorporated into the manipulation of the cold-water valve opening, along with other constants. To optimize the constants used in the fuzzy logic, the system developed experimentally was modeled in MATLAB using an energy balance and the Simulated Annealing optimization method. As a result, it was possible to determine the best parameters for the defuzzification equations of this system for application in the temperature controller prototype.

Once upon a time, there were Alice (not the one from Wonderland) and Dorothy (not the one from Oz), but two dedicated teachers from the municipal public school system, passionate about mathematics. Alice spent her childhood on a farm surrounded by nature, amid the affection of her family and playing with her two sisters. Dorothy grew up in a bustling, urbanized capital city, where she shared her daily life with two brothers and the constant presence of her mother. One day, both decided to follow paths far from their origins. They faced challenges, took unexpected routes, but ended up rediscovering the meaning of their trajectories in teaching. Children, education, and research groups welcomed them back, allowing their enchantment with the profession to flourish in a different way. This thesis narrates the formative adventures of these two teachers, guided by the following research question: How do teachers who participate in research groups strengthen their teaching practices in Early Childhood Education when addressing mathematical knowledge? The general objective of the research is to understand the strengthening of teaching practice in relation to the mathematical knowledge of Early Childhood Education teachers, based on narratives about their experiences in research groups. As specific objectives, this research problematizes aspects of the formative processes and knowledge construction revealed by early childhood education teachers in relation to mathematical knowledge in childhood through their oral narratives; and identifies evidence of the strengthening of these teachers' pedagogical practice in the pedagogical work developed with early childhood education children involving mathematical knowledge. To answer this question and meet the research objectives, I mapped the research groups registered in the CNPq Directory that address Mathematics Education in Basic Education, selecting those that specifically address Early Childhood Education. It was during this process that I met Alice and Dorothy, through narrative interviews conducted online. Based on research with narratives and hermeneutics, the analyses were organized into narrative notes, based on the contributions of Jovchelovitch and Bauer (2002) and Clandinin and Connelly (2015), highlighting the intertwining and distancing that emerged from the stories of these teachers. With Alice and Dorothy, I learned about the power of continuous training movements in research groups and how these collaborative spaces impact pedagogical work in early childhood education. Both invite us to (re)think mathematical knowledge in a sensitive and situated way—a mathematics that is possible, lived, and experienced by children in their daily lives. They taught me that, in early childhood education, “there are no students or homework, but experiences; there are no tasks, but experiences.” Thus, mathematics takes shape and meaning in experience—a meaningful mathematics that arises from listening to children and is built on what they live and feel.

This research proposes an investigation into sugarcane production in Brazil and Latin America, using a Science, Technology, and Society (STS) perspective to analyze the environmental, social, and economic impacts of the sugarcane industry and its potential for science education. The study seeks to understand how technological choices influence the daily lives of communities in producing regions and how to promote teaching practices focused on these aspects. Our discussions aim to highlight the interaction between science, technology, and society in science education, addressing sugarcane as an interdisciplinary theme that allows for the discussion of historical, biological, chemical, and social aspects, as well as its labor and environmental implications. The research was conducted through bibliographic and documentary research, which involved the collection, selection, and critical analysis of various scientific publications related to sugarcane cultivation and its relationship with science education. For data analysis, we used Content Analysis, a method that enabled the identification and organization of relevant thematic categories to understand the contributions of the topic to science education guided by STS (Science, Technology, and Society). The selected sources address technological, socio-environmental, and educational aspects of sugarcane production, allowing for an interdisciplinary and critical approach to the topic. Through this approach, we aim to develop in students the competence to interpret and critically question socio-scientific dilemmas, encouraging conscious and responsible action in the face of current socio-environmental challenges.

Drying is an essential unit operation in various industrial processes. For the efficient design of dryers on an industrial scale, bench and pilot-scale studies are fundamental, as they provide specific kinetic information about the products, such as the film coefficients associated with heat and mass transfer phenomena. However, experimental data obtained in drying systems often exhibit noise and uncertainties, frequently resulting from limitations in the methodology used for data collection, such as fluctuations in the electrical network or interference during weighing caused by vibrations and equipment instability. In this context, the objective of this work was to develop a software aimed at processing experimental data from a forced convection oven, focusing on data treatment and the extraction of relevant kinetic information for the study of drying. For testing the program, drying data of manganese ore were applied, and an analysis of the results obtained with the developed tool was also performed. Python routines were created for the processing and analysis of balance data, capable of: generating drying curves; comparing experimental data with theoretical diffusion models and with literature data; applying filters to the data; and storing the results. The program was complemented with textual material and instructional videos to facilitate its use. The test with manganese ore demonstrated the efficiency of the tool in visualizing the drying stages. A critical moisture content value between 0.10 and 0.15 kg water/kg dry solid was identified for 21 mm manganese spheres, dried at 90 °C. The theoretical models of Lewis and Page proved to be suitable for describing the drying rate, showing correlation coefficients greater than 0.98.

The present Final Course Project, entitled “Drying Behavior Analysis of Iron Oxide in an Oven”, proposes the study and characterization of the drying process of two important inorganic pigments widely used in industry: yellow iron oxide (Goethite, α-FeOOH) and black iron oxide (Magnetite, Fe3O4). The drying stage is a fundamental unit operation in the manufacture of pigments, exerting direct influence on the properties of the final product, such as crystallinity, particle size, and tinting strength. The main objective of this work was to analyze the variation of moisture content and the drying rate of samples of these materials in an oven under controlled temperature conditions, aiming to obtain empirical data to optimize energy efficiency and processing time. Gravimetric tests were conducted at temperatures of 100 °C, 110 °C, and120 °C. The theoretical foundations indicate that the structural differences between Goethite, an oxyhydroxide with high affinity for water, and Magnetite, an anhydrous oxide with a compact structure, are determining factors for their kinetic behavior. The experimental results confirmed that Goethite exhibited higher moisture retention and a longer drying time, with kinetics predominantly in the falling-rate period, limited by internal diffusion of bound moisture. Magnetite, on the other hand, demonstrated a significantly faster drying process. Increasing the temperature from 100 °C to120 °C resulted in a reduction of the total drying time for both samples. It was concluded that the drying process of Magnetite is more favorable in terms of speed and potentially energy consumption, providing important comparative results that serve as a reliable starting point for the analysis and further investigation of the materials in question.

Natural gas and refinery gas conditioning requires the removal of carbon dioxide (CO2) and hydrogen sulfide (H2S), contaminants that affect operational safety, equipment integrity and environmental performance and must comply with strict quality limits established by Brazilian regulation for commercial gas. In this context, thermodynamic models able to represent, with reasonable accuracy and moderate complexity, the solubility of acid gases in aqueous amine solutions are key tools for the design and optimization of gas sweetening units. This work aims to model the equilibrium between CO2, H2S and aqueous solutions of monoethanolamine (MEA) and diethanolamine (DEA) using the Kent–Eisenberg model, formulated with apparent equilibrium constants and effective Henry coefficients regressed from experimental data. The methodology is based on the numerical implementation of chemical-equilibrium relations, elemental balances and electroneutrality, coupled to vapour–liquid equilibrium equations, and on the iterative solution of this system for different acid-gas loadings, temperatures (25 – 140 °C) and solvent concentrations representative of industrial operation (15 – 40 % m/m). Model validation was carried out by comparing simulation results with solubility data from the literature for aqueous MEA (15.3 wt% at 40 °C) and DEA (19.3 wt% at 40 °C) solutions in the presence of CO2 and H2S simultaneously. The results show satisfactory quantitative agreement, with average deviations of 6% for H2S and 16% for CO2 in MEA, and consistent performance for the DEA system, with average deviations of 12% for H2S and 10% for CO2. The equilibrium curves correctly reproduce the increase in partial pressure with temperature and gas loading, as well as the higher relative solubility of H2S compared with CO2. Predicted pH trends and speciation patterns are physically consistent and highlight the different roles of carbamate and bicarbonate in primary and secondary amines. It is concluded that the Kent–Eisenberg model satisfactorily describes CO2 and H2S solubility in MEA and DEA over the analysed operating ranges, providing a consistent basis for process design and for improving the energy and environmental performance of acid-gas removal units.

The separation of benzene and thiophene is a relevant challenge in chemical engineering due to the low relative volatility difference between the components and the presence of sulfur in thiophene, which compromises fuel quality and catalytic activity in refining processes, making it essential to employ thermodynamic models capable of accurately representing the vapor–liquid equilibrium (VLE). In this work, different models available in the Aspen Plus simulator were evaluated to represent the binary benzene–thiophene system, using experimental data available in the literature as reference. The qualitative analysis consisted of comparing simulated T–x–y curves with experimental points, while the quantitative analysis was carried out through the calculation of root mean square deviations (RMSD) in temperature and vapor-phase composition. The results showed contrasting performances: the Peng–Robinson equation of state presented the lowest deviation in temperature (RMSD = 0.1845 °C), confirming its robustness in thermal prediction, while the Soave–Redlich–Kwong model stood out in representing the vapor phase, with RMSD in composition of only 0.0009, evidencing greater fidelity in predicting equilibrium compositions. The UNIQUAC model demonstrated balanced performance, with RMSD of 0.2364 °C in temperature and 0.0017 in composition, followed by NRTL, which presented 0.3448 °C and 0.0032, respectively, confirming intermediate results. In contrast, the correlational models Chao–Seader and Grayson–Streed exhibited the largest deviations, with RMSD in temperature of 1.0735 °C and 1.2690 °C and composition errors above 0.008, while UNIFAC, despite its predictive nature, showed RMSD of 0.8707 °C in temperature and 0.0090 in composition, confirming its limitations for aromatic systems containing sulfur. Therefore, it is concluded that Peng–Robinson and SRK are the most suitable models to represent the studied system, each excelling in a specific variable, with UNIQUAC emerging as an intermediate alternative capable of providing consistent results in both variables, although without surpassing the performance of cubic equations of state.

This research take as its central theme the concept of Museum Education and its epistemology. Considering the current state of the field in a phase of consolidation, there are theoretical challenges to be faced on the path toward its emergency, such as the precarious conditions of the area or of the lack of recognition among peers. For this the study utilizes translation as its methodology which enables the articulation of different points of view, inspired by an anarchism, both political and epistemological. The thesis is presented through the narrative of a simbolic journey that initiates in the desert of difficulties, translating the current limitations of the field; after this, in order to heal and rehydrate, it seeks out the fountains, historical fountains to estabilish a relationship of appropriation, translating autonomy and creation; continuing, the path goes into the forest to describe the educational process of discovery, translating language into educational action; further ahead, it presents the Navigation Map, as a structuring metaphor of the work organizing epistemological elaboration, translating an orientation tool into an instrument of action; from this theoretical-methodological basis, a process of cartography is initiated to imagine the possibilities of the emergence of this concept, composed of a territory and a settlement, a space of political articulation among dispersed perspectives with the goal of collective recognition; in the end, the path takes a detour into the woods to explore an insurgent subjectivity which caracterizes the proposal of Museum Education as it is experimented within this work.

Introduction: Pregnancy is a period in which uncertainties, fears, and anxieties may emerge, in addition to confrontation with myths lacking scientific evidence and the changes that occur in the social context and, especially, within the pregnant woman’s family environment. Primary Health Care (PHC) is responsible for comprehensive, continuous, and person-, family-, and community-centered care. In this context, educational groups are understood as resources that provide biological, social, and psychological care, creating a space for the exchange of experiences, support, empowerment, sharing of doubts, and strengthening of bonds among pregnant women, family members, and health professionals. Objective: This study aimed to analyze the implementation of Health Education Groups for Pregnant Women in Primary Health Care in Brazil through a literature review. Methodology: The search for theoretical references was conducted in the CAPES Journal Portal, which initially identified 192 studies; of these, 33 were analyzed in depth, and 29 met the inclusion criteria. Results: The findings of the review made it possible to propose updates and suggestions that may contribute to improving the quality of the Ministry of Health’s guiding materials by incorporating new and emerging themes that are still scarcely addressed in pregnancy groups. The studies also showed that these groups contribute to improving the quality of prenatal care, expanding pregnant women’s knowledge, strengthening autonomy and self-care, and including the family in the gestational process. Conclusion: Educational groups for pregnant women in PHC in Brazil are essential tools for promoting a safer and more humanized pregnancy. In this sense, the results of this review support and expand the focus of current policy, demonstrating that pregnancy groups in PHC have the potential to meet contemporary demands proposed by the Alyne Network. Furthermore, the renewal of themes highlights the relevance of integrating Occupational Therapy into this context.

Brazil’s citrus industry is the global leader in orange juice production and exportation. However, fruit processing generates a significant amount of residues, such as peel, seeds, and pulp, which account for nearly 50% of the total mass, creating both environmental and economic challenges. Currently, these residues are largely converted into Citrus Pulp Pellets (CPP), a low value-added byproduct used as animal feed. Considering the need to improve biomass utilization efficiency and align the sector with circular economy principles, this study evaluated alternative routes for the valorization of orange processing residues by characterizing the production chain, describing the main waste streams, and reviewing technological pathways based on market data and scientific literature. The assessment identified relevant opportunities to produce pectin, ethanol and biogas. Based on these findings, an integrated biorefinery configuration was proposed, designed to complement the existing juice-processing infrastructure and optimize material flows, reduce losses and increase product diversification. Although the economic analysis considered only the potential market value of the resulting coproducts, without accounting for operational or capital costs, the results indicate that the valorization of orange residues represents a promising strategy to make the citrus chain more sustainable, innovative, and aligned with global demands for low-impact industrial processes.

The increasing demand for bone implants to treat diseases or injuries has driven the search for new approaches capable of providing functional substitutes. These solutions, known as scaffolds, aim to address tissue scarcity and adapt in a personalized manner to the individual needs of each patient. To be effective, these scaffolds must exhibit biocompatibility, controlled bioresorbability, mechanical stability, and the ability to promote cell adhesion, proliferation, and differentiation. Therefore, this study aimed to develop biocomposite scaffolds composed of a blend of poly(lactic acid) (PLA) and poly(butylene succinate) (PBS) in a 75:25 (% w/w) ratio, incorporating two biofillers: β-tricalcium phosphate (TCP) or bone powder (BP). The biocomposites were produced by melt mixing in an internal mixer and subsequently subjected to rheological and thermal characterizations before being used to manufacture 3D-printed scaffolds. The incorporation of biofillers resulted in a small reduction in the viscosity and thermal stability of the blend, indicating possible polymer degradation induced by the addition of these biofillers. Despite this, the 3D printing process demonstrated excellent morphological reproducibility, resulting in scaffolds with adequate structural integrity for bone repair applications. Mechanical tests revealed that the addition of biofillers (10% and 20% w/w) did not significantly enhance mechanical performance and ensured compatibility with natural bone tissue. In vitro cytotoxicity tests, performed with mouse pre-osteoblastic cells (MC3T3-E1), confirmed the biocompatibility of the scaffolds, evidenced by good cell adhesion and the absence of toxic effects. The results indicate that PLA/PBS (75/25) scaffolds with TCP and BP have great potential for applications in bone tissue engineering, as they combine processability, mechanical stability, and bioactivity.

Lubricants are of paramount importance in all facets of modern industries. Most are of fossil or mineral origin, which makes the production chain of such materials harmful to the environment. These resources are finite and, although it may take time, they will eventually run out. In this context, biolubricants emerge as a viable alternative to traditional lubricants due to their biodegradability and the possibility of being produced from renewable sources. One possibility is the production of biolubricants from ester synthesized with castor oil. This involves first undergoing hydrolysis reactions of the castor oil, catalyzed by an enzyme Eversa Transform 2.0 to obtain free fatty acids from the oil, a process that had a conversion rate of 86%. This is followed by esterification reactions, also catalyzed by Eversa Transform 2.0, of these fatty acids with isoamyl alcohol, obtained from fusel oil, a byproduct of ethanol production, which had a conversion rate of 81%. Finally, epoxidation reactions of the formed ester were conducted as a strategy to improve its performance as a biolubricant. This epoxidation reaction yielded 14% of epoxidized ester. This work discusses the main challenges of biolubricant as well as ways to mitigate these challenges.

Galactooligosaccharides (GOS) are nondigestible oligosaccharides composed of chains of 2 to 8 units of galactose and glucose. Their production starts with lactose, an abundant byproduct of the dairy industry, via an enzymatic reaction known as β-galactosidase-catalyzed lactose transgalactosylation, generating a complex mixture of di-, tri-, and tetrasaccharides. Key benefits of GOS include the stimulation of the intestinal microbiota, the blocking of pathogen adhesion in the digestive tract, and the enhancement of mineral absorption. In addition to their physiological effects, GOS are widely applied in food formulations due to their high water solubility, thermal stability, and resistance to pH variations. These characteristics make GOS highly attractive to the food industry and motivate the development of optimized processes for their production. Such processes, when operated at scale, require effective reactor control to minimize product losses from hydrolysis and determine a satisfactory stopping point for batch processes. This highlights the need for robust and precise monitoring methods capable of providing real-time process information. Direct online measurement techniques, such as spectrometric methods, can provide real-time measurements of some process variables. However, these techniques have limitations both in terms of the variables they can measure and the noise present in their measurements, which can restrict their usefulness for control purposes. By combining a fundamental model of the system with online measurements, it is possible to leverage more system information, thereby achieving improved monitoring and control performance. This combination is enabled through state estimators which, in general, first perform a prior estimate of the state based on the model and then receive a system measurement and apply a correction, providing a posterior estimate. The present study seeks to explore the capabilities of two types of state estimators - the Particle Filter (PF) and the Extended Kalman Filter (EKF) - for performing real-time monitoring of a GOS synthesis, described mathematically by a kinetic model and measured using a UVVis probe. Despite the greater complexity and computational cost of the PF, the results showed that, when starting from well-defined initial conditions with low uncertainty, the performance of both estimators was similar. However, when using an initial condition far from reality and with higher uncertainty, the PF showed superior performance compared to the EKF, converging more rapidly to the experimental data and achieving errors approximately half those obtained by the EKF for most of the estimated species.

The Node.js platform is widely used for JavaScript applications, employing an asynchronous execution model that is essential for its performance. However, the non-determinism of this model can lead to event races, which are subtle and hard-to-reproduce concurrency bugs that compromise software reliability. Current approaches to detect event races often require exhaustive analyses on the entire test suite, resulting in high computational costs and a lack of effective mechanisms to select and prioritize automated tests that are more susceptible to event races. This work proposes and evaluates an approach called NodeRock, which uses dynamic analysis to identify and select tests susceptible to event races in Node.js projects. NodeRock collects detailed execution traces, extracts a set of 15 dynamic features that characterize asynchronous behavior, and uses machine learning to select the tests. The results provide evidence that the approach identifies tests susceptible to event races with 75% accuracy and recall exceeding 84%, suggesting that the analysis of dynamic metrics is a promising strategy for prioritizing the investigation of these tests.

The health of Indigenous populations is a topic that remains underexplored in the health field, especially with regard to policies that guide the provision of differentiated care for these groups. Understanding such policies and Indigenous health care practices is essential for Occupational Therapy professionals and other health professionals to promote intercultural care that respects the cultural specificities of each people/ethnic group. Currently, it is estimated that approximately 1.6 million Indigenous people live in Brazil, belonging to more than 300 ethnic groups and speaking 274 different languages. These groups face historical and contemporary challenges related to the guarantee of their rights, ways of life, and cultures, which are marked by prejudice and stereotypes. Objective: To identify and analyze the existing literature on the implementation of practices and strategies carried out by health professionals with Indigenous social groups, as well as to understand how the National Policy for Health Care of Indigenous Peoples (PNASPI) has been addressed and implemented in this context. Methodology: This study consists of a literature review conducted using the integrative review method, with the aim of highlighting how health professionals have provided care to Indigenous populations. The review seeks to understand which care practices and interventions have been implemented, as well as how the National Policy for Health Care of Indigenous Peoples has been put into practice. The selection of materials included different types of academic productions, with no restrictions regarding the period of publication.

This final course project (TCC) is part of a larger Scientific and Technological project and focuses on mental health and the intersectionalities of gender, class, and race, intending to study the promotion of mental health among and with women in peripheral areas through everyday knowledge and practices. Goals: This research aimed to identify, understand, and analyze with a group of women the activities they perform in their daily lives to promote care and mental health for themselves and other women. Methodology: This was a qualitative, participatory study conducted with a group of seven women who are members of a community collective and residents of a peripheral region of a municipality in the interior of the state of São Paulo. Data was collected through four meetings. Data analysis was carried out in a procedural manner, together with the women, so that each meeting could be aligned with the previous one. All syntheses were constructed and validated collectively, as they constituted the new knowledge produced by the participants with the support of the responsible researchers. Results: The results that were explored in depth and presented in this final project point to the importance of denaturalizing care by women, revealing the intersections that traverse it, the possibilities of access or lack thereof, the problematization surrounding care practices and their analysis, indicating that the act of caring for women is a revolutionary act, often not performed even to ensure one's own life. It is considered that the study provided important insights for thinking about women's health within the SUS, providing clues for the construction of participatory and popular care technologies. Finally, it is indicated that the work contributed to the fields of Mental Health and Occupational Therapy, Popular Education in Health, Psychosocial Care, and other areas that work with women living in vulnerable regions.

This Final Course Project aimed to examine how Brazilian education for students with disabilities and social vulnerability enrolled in basic education occurs. From a critical and reflective perspective, the study seeks to understand how social vulnerability intensifies educational exclusion processes and how teacher training can contribute to the implementation of truly inclusive pedagogical practices. The work was developed through bibliographic and qualitative research, based on scientific articles, legislation, and official documents published between 2015 and 2025. Productions addressing the National Policy on Special Education from the Perspective of Inclusive Education, the role of public schools, and the performance of teachers in the face of structural and social inequalities permeating the Brazilian educational context were analyzed. The results showed that, although Brazil has a solid framework focused on inclusion, there is still a significant gap between what is stipulated in legislation and the reality experienced in schools. The research indicates that the lack of ongoing teacher training, the absence of adequate infrastructure, the scarcity of pedagogical resources, and the fragility of intersectoral policies are factors that compromise the effectiveness of inclusion. Furthermore, the analysis shows that neoliberalism and capitalist logic contribute to the maintenance of educational inequalities, since quality education remains a privilege of the most favored social classes.
