With RSA Cryptography as background, we present, generally speaking, the mathematical theory that underlies that encryption model, as well as its contextualization as part of the modern way of life and its security, and then proposes a product for Basic Education (BE). For this, we show the Brazilian National Common Core Curriculum (BNCC) view about the use of technologies in the mathematics teaching in addition to possibilities for the use of calculators in Elementary School (ES) classes. Before, however, basic elements of Modular Arithmetic are presented, building the mathematical model that supports RSA Cryptography - in addition to the totient function, as an additional topic. Thus, guided by the question “Is it possible to bring the RSA Cryptography theme to the Basic Education classroom?” our goal is to createactivities in which, from the use of technologies, modular arithmetic concepts are addressed, leading students to understand the RSA Encryption method. As a result, we present the final product, aimed at Basic Education, consisting of a proposal for didactic sequence for the 6th year of Elementary School, which aims to introduce the concept of primality using calculators, and two proposals for classes for the High School, approaching the calculation of residual powers through Modular Arithmetic, sometimes with manual calculations, sometimes with electronic spreadsheets. There are also suggestions on how can be approached the activities proposed in the High School. Finally, it is concluded that this work can be a guideline for future studies, research and practices, so that its elaboration and conclusion were successful in the sense of giving continuity to the formation of a teacher who teaches mathematics in Basic Education.

Financial Education promotes the development of personal skills, enabling greater conditions for the individual to make decisions in the financial framework. Regarding its relevance, Financial Education area has been increasingly growing, gaining space in several fields over the last years, especially in school context. Such scenario justifies this masters research conducted in Programa de Mestrado Profissional de Matemática em Rede Ampla (PROFMAT) at the Centro Federal de Educação Tecnológica de Minas Gerais-CEFET-MG, that aims to address and discuss issues regarding Financial Education in Basic Education, with the objective of creating a didactic sequence that addresses financial investments theory, for students in the 9th year of Basic Education (in Brazilian system) and investigate whether this sequence contributes to the financial education of these students. This research is qualitative and the methodological procedures used were participant observation, questionnaires, audio and video recordings. The development of activities was based on a didactic sequence, elaborated within the perspective of Scholar Financial Education under the guidelines provided by the Brazilian National Strategy for Financial Education - ENEF (2011) and the Brazilian National Common Curriculum Base - BNCC (2018). Thus, the didactic sequence explores themes such as Financial Education, Financial Mathematics, the Citizen Calculator (Calculadora do Cidadão), interest rates, the Brazilian Selic rate, inflation, fixed income investments and variable income investments. The sequence was remotely performed due to the COVID-19 pandemic, in a mini out-of-class course format consisting in four meetings of one-and-a-half-hour duration each. Then, we analyzed the discussions raised during the mini-course and the material collected. The analyzed data lead us to believe that the development of this sequence provided an opportunity to discuss concepts and financial aspects, promoting the students' Financial Education. Reiterating the importance of School Financial Education, we expect that this research and its results could also stimulate and assist teachers that wish to work with Financial Education in Basic School.

The RPG, an acronym for Roleplaying Game, is a game that mixes roleplay and a set of probability-based luck tests. The objectives of this dissertation are to explore the application of RPG in mathematics education in order to develop a system that is easy to apply in a school environment and, based on this system, a Probability manual for Elementary School. To develop the system, the following was explored: the trend of Games in Education, Roleplay in education and the existing works with similar objectives. For the Probability manual, we explored three Brazilian syllabuses and the mathematical definition of the topics to be discussed in class.

With the great popularity of microcomputers, smartphones and Internet access, developing methodologies that meet the needs of a generation of digital natives is a new challenge for educators. In this context, gamification can be applied to teaching and learning processes. However, making use of gamification requires much more than using games, being necessary for the teacher to understand how this tool is structured, putting him in the role of a facilitator, instead of a transmitter of knowledge. The aim of this work is to comprehend how to use and insert into teaching practices the mechanics, dynamics and aesthetics present in games. Furthermore, we propose the implementation of a game for teaching first degree polynomial equations. We present the context and dynamics of the game and schemas that specify a future implementation.

Resumen Espectáculo

The concept of Probability is part of a society’s day-to-day, whether it is in simple situations, for instance event occurrence; or more complex circumstances, like decision-making processes that require logical thinking. Therefore, understanding probability is fundamental both in and outside the academic environment. That way, we have explored interesting and relevant ways to deal with this subject in a dynamic and playful approach, choosing to apply it on educational-biased games. Thus, the present study uses the Monty Hall Problem (MHP), greatly discussed by scholars, as a background to improve assimilation and comprehension of probability conceptions and properties. In doing so, we have developed a GeoGebra Book, made of theoretical materials involving diverse complexity levels of probability content. In addition, the digital book includes solved exercises in games, such as dice and cards, as well as applets that allow its use through adapted games and PMH expansion into other doors. The final product will serve as support material for high school students and teachers, or anyone enthusiastic about the topic. The proposed e-book connects applied probability axioms to game playing; encouraging users to foster and enhance concepts that will help them solve problems on a daily basis.

Considering the importance of Numerical Calculus as a mathematical tool, in this paper we study some of the main techniques for approximating roots of real functions and explore their application for teaching this subject in Basic Education (BE). After the theorization of three of the main numerical methods for calculating roots of real functions, we explore some of their potential for application in the BE classroom. For this, besides using computer environments in the construction of the classes, we took into account skills related to computational thinking from the perspective of the NCCB (National Common Curriculum Base). Then, we analyze a selection of productions the PROFMAT (Professional Master in Mathematics in National Network), in order to investigate how this post-graduate program produces for the BE, focusing on the topic of calculus of function roots and numerical approximation techniques. Finally, we present our final product, a proposal for a Didatic Sequence, composed of lesson plans that work as skills related to computational thinking through computerized environment. We conclude that the composite activities have relevance to bring the subject of Numerical Calculus to the BE classroom.

Several are the difficulties reported by teachers and students throughout the teaching-and- learning process in mathematics, particularly in what regards the content of Probability. The present dissertation has as its objective to analyze how a didactic sequence, developed through the use of Team-based learning (TBL) strategy may contribute to enhance not only teaching, but also student learning outcomes. The sequence in question, had initially been planned to be developed in remote (online) environment due to the COVID-19 pandemic. Nevertheless, in August 2021, students were allowed to partially return to school in smaller groups. Each of these groups would attend school, in person, every two weeks. After that, the nearly total return of students finally took place in September 2021. Hence, it was decided to adapt and change our initial planning and apply both the questionnaires and the didactic sequence in presential manner. In order to develop the project and the didactic sequence, an initial diagnostic questionnaire was applied, two different methodological paths were built and developed and students were subjected to a final questionnaire. The methodological path 1, involved the concepts of Sample Space, Event and Randomized Experimentation, the classic definition of Probability and the Probability of the union of two or more events. The methodological path 2, referred to the Probability of Independent Events and Conditional Probability. Both methodological paths were developed, based on TBL Teaching-and-Learning Strategy, in a class of 43 students of the 11th grade of high school, from a private school in Belo Horizonte. The data collected along the applications was registered and analyzed through a qualitative approach of interpretative base, being open-ended answers of students analyzed in a way that these would reveal relevant information regarding the students’ learning in what regards the content of Probability. These answers showed, for instance, that students apprehended the classic definition of Probability, but they also highlighted that the same students presented gaps related to contents from junior high school and from the 10th grade. It is important to emphasize that we were returning from an extended period of pandemic, what might have worsened this perception of possible learning gaps and in knowledge regarding the content of previous years. With the development of the didactic sequence, the participation and the answers from students,it was possible to notice that the teacher, as a mediator/tutor, has an important role in the construction of the students’ mathematical knowledge and that the teacher should always follow the signs of time, proposing different teaching-learning strategies in order foster the construction of learners’ mathematical knowledge, placing them as protagonists in the process, making mathematics interesting and meaningful for them.

In our daily lives, wherever we look, we find applications of Mathematics. However, this is not always easily noticed by everyone. This work produced a booklet intended to show the application of Mathematical methods and techniques to calculation of materials in Civil Construction. We offer straightforward solutions to problems that individuals may encounter in their lives, whether working in construction or planning a renovation or construction. In this approach, we present the concepts of proportion, perimeter, area and volume at high school level. We also propose digital technologies as teaching motivators for Mathematics, therefore we use the free program Sweet Home 3D, which can be used to model a building. We believe that presenting concrete and specific examples of the application of Mathematics is a motivator that contributes to student learning.

This work is based on the studies of Markov Chains and Chapman-Kolmogorov Equations. To understand the text in Annexes A and B, there is a relevant review about Matrix and Probability, topics covered in the basic education level, usually in the second year of high school. After the review of those topics, it is possible to approach basic concepts of Markov Chains and their different applications. Markov Chains have numerous applications in economics, genetics, mathematical problems, and their main characteristic is that the determination of future probability does not depend on past probabilities, but it only depends on present probability. The objective of this work is to introduce the basic concepts of Markov Chains to second year high school students using an approach of Matrices and Probability that they are already familiar with, presenting them with interesting examples, instigating their curiosity, seeking to motivate them during the learning process and demonstrating how mathematics is useful, necessary and can be applied in several ways in the world around us. Finally, with the suggestion of a didactic sequence, we want teachers and students to have a rich experience and a significant learning of the basic concepts of Markov Chains and Chapman-Kolmogorov Equations after Matrices and Probability. The didactic sequence has five consecutive stages with an increasing degree of complexity, seeking to provide students with a specific, defined learning process and that they, through their abilities, reach new levels of learning.

The study of functions in Basic Education represents an important moment in the evolution of mathematical thinking and the development of modeling problems involving the content of functions. In order to support teachers and students in the teaching and learning process of the content of functions, as well as to bring practical applications that solidify knowledge and bring together mathematical concepts and everyday situations, this work contains a booklet for autonomous studies and video lessons for better guidance. learning development. It is expected that, with the support of teachers and textbooks, the student will be able to understand phenomena and model them. For the development of this work, we surveyed the dissertations produced within the scope of PROFMAT that deal with the teaching of functions and are intended for classes from 9th grade of Fundamental II, 1st to 3rd grade of High School and we rely on teaching strategies and learning such as flipped classroom and problem-based learning (PBL). The application must take place in the classroom, in the face-to-face model, so that it is possible to recover important content in the development of mathematics teaching, especially considering the gaps perceived in the post-COVID-19 pandemic period.
