Título: Funções convexas com aplicações no ensino médio Abstact: In the context of high school education, understanding the principles of convex functions not only enriches students' mathematical comprehension but also prepares them to face practical challenges across various fields. However, the study of this topic faces obstacles related to the complexity of the subject and the need for essential didactic resources. This study aimed to identify effective strategies for teaching sets and convex functions, promote the development of students' critical thinking and analytical skills, and evaluate the impact of these strategies on students' preparation for advanced studies and their perception of the relevance of mathematics. To achieve this, a literature review on mathematics education was conducted, analyzing pedagogical practices and implementing a didactic approach based on visualizations, real-world examples, and interactive activities. The study indicated that introducing the concepts of sets and convex functions in a contextualized and practical manner enhances students' understanding and increases their engagement with mathematics. It highlights that a well-structured pedagogical approach, incorporating practical examples and associative activities, transforms abstract mathematical concepts into practical and relevant tools, preparing students for critical thinking development and future perspectives.

Título: Relações entre a filogenética via DNA Barcode e traços funcionais de minhocas na Amazonia Oriental Abstact: Understanding the causes of variability in functional traits is an important question in earthworm ecology. While interspecific variation in anatomical dimensions for the same trait is well accepted, the role of environmental filters, soil degradation, and environmental stress in affecting the variability of functional traits is not well understood. In this study, we sought to determine the relative importance of environmental factors and earthworm species taxonomy on the variability in functional traits within species (intraspecific variability). We focused on eight functional traits including body mass, body length, body diameter, gizzard, gizzard thickness, septum thickness, typhlosole, and gut organic matter. We sampled earthworms of 11 different species in various regions of the eastern Amazon to determine the general responses of different species' characteristics when exposed to various ecosystem and soil conditions. Our results suggest that the functional traits of earthworms are influenced in different ways by environmental conditions. One set of traits, including body mass, body length, and body diameter, was more constant and independent of environmental variability, while another set, including gizzard diameter and length, gizzard muscle thickness, septum thickness, typhlosole, and intestinal organic matter, was more sensitive. The most affected by different environmental variables was septum thickness. We also examined which environmental factors are most important for trait variability. Our study highlights the importance of considering both environmental factors and taxonomic classification when studying the variability of functional traits within earthworm species. Overall, our results suggest that taxonomic classification alone is a good guide for estimating the major functional traits of earthworms in the Brazilian Amazon, but local conditions can their variability is which is essential for informing conservation efforts and maintaining ecosystem function. In the second chapter of this thesis, we focused on the utilization of the molecular tool known as DNA Barcodes, which enables the identification of species groups with unknown taxonomy. The utilization of DNA Barcodes produces UOTMs (Molecular Taxonomic Operational Units), which can serve as morphospecies to characterize the diversity and structure of communities, as well as to investigate the relationships between soil attributes and ecological processes. Thus, the objective of this study was to explore the potential of DNA Barcodes in assessing phylogenetic diversity. Specifically, we utilized the COI gene region to analyze new species of annelids and compare their identification with classical taxonomy. We extracted DNA from a total of 1,014 earthworm samples; however, only 56 samples were successfully sequenced. Despite encountering technical challenges during the sample amplification and sequencing process, our results revealed the formation of clusters among earthworm species and certain genus-level groups, which had already been identified through classical taxonomy and were further supported by phylogenetic analysis (e.g., Pontoscolex and Andiorhinus) due to their significant similarity to existing databases. In conclusion, the data presented in this chapter necessitate revisiting and repeating the amplification and sequencing procedures to ensure accuracy and reliability

Título: O ensino de matemática sob a ótica da educação inclusiva: diálogos, desafios e possibilidades Abstact: Inclusion has been a subject of great debate and relevance worldwide, awakening different opinions and feelings. Thus, the research addresses the intersection between mathematics education and inclusion, providing perspectives, resources and strategies necessary to ensure that all students have access to quality and inclusive mathematics education. Through a qualitative approach, the research addresses the theme: Mathematics teaching from the perspective of inclusive education, investigating the main challenges encountered by teachers and pointing out possibilities for pedagogical practices. To this end, we sought to answer the following question: How can teaching mathematics contribute to inclusive education in the sense of enabling dialogues that challenge and promote learning? In order to answer the question we highlight the general objective of investigating possibilities and challenges of teaching mathematics from an inclusive perspective in the final grades of Elementary School in the city of Brejo - MA. The research aimed to identify theoretical bases of inclusion policies at national, state and/or municipal level, in addition to building reflections on the difficulties encountered by mathematics teachers in the context of inclusion, on the training of mathematics teachers to meet diversity, but also proposes thinking about ways to promote accessible mathematics teaching through trends in mathematics education. To this end, it presents a didactic sequence that explores the use of news as a pedagogical tool to encourage inclusion in Mathematics classes. The foundation of the research is established in the conviction that Mathematics teaching can should be accessible to all students. The expected result is the recognition that although there are significant challenges to be faced, there are reasons to be optimistic about inclusive mathematics teaching.

Título: Metodologias ativas aplicadas ao ensino de matemática: o STEAM como ferramenta pedagógica nas aulas de matemática Abstact: Active methodologies when combined with STEAM Education can provide opportunities to prepare students to face the challenges of the future as they take on the protagonist role in their learning, however, teachers need to use teaching strategies that encourage active participation, in the context of transformation that took place in recent years, impacted the profile of students, diverting their interests within the school, since they are completely immersed in the digital world and traditional practices of teaching math in education basic education did not reach the educational objectives, therefore, we sought understand “How the active methodologies – with a STEAM approach – can be used as important pedagogical tools in math classes?” The problematizing question was guided by the general objective, researching how active methodologies, with an approach to STEAM, can be applied in math teaching taking into account the stipulated guidelines by BNCC. The proposed objective was detailed in smaller actions, such as: carrying out bibliographical research on active methodologies, focusing on STEAM education - its characteristics, principles and applications in the school context. identify at BNCC guidelines that stipulate condition and encourage the use of active methodologies in the teaching of math. Examine educational practices, with emphasis on robotic tournaments from FIRST, who applied STEAM as enhancers in teaching science and math, in addition to developing three didactic sequences with objects of knowledge described in BNCC, which has as background the use of STEAM education. In the effort of proving the effectiveness of active methodologies mediated by STEAM alternatives, a didactic sequence was applied with a first year of high school in a private school in São Luís. To collect research data, two questionnaires were administered, one to students from the research field school that has participated in robotics tournaments, and other for students who participated in the application of the didactic sequence, the researched data suggests that technology-mediated teaching can offer attractives and awaken young people to more meaningful learning, as teachers need to be trained to meet society's criteria.
