Esta dissertação é fruto de um processo de reflexão sobre a minha experiência pro fissional de nove anos de serviço, como docente de matemática, bem como do interesse pela análise do processo de aprendizagem que os alunos do sétimo ano de escolaridade fazem das noções elementares da álgebra. Para realizar esta investigação, foi selecionada uma turma de sétimo ano, em que a maioria dos alunos é interessada pelo seu percurso escolar, embora, por vezes, não sejam constantes na sua prestação em sala de aula, bem como na realização do estudo correto em casa. Neste estudo, optou-se por uma metodologia de natureza qualitativa, de caráter interpretativo. O estudo das noções elementares da álgebra no sétimo ano de escolaridade é um marco de suma importância no percurso escolar dos alunos. É no sétimo ano de escolaridade que estes têm o primeiro contacto com noções elementares da álgebra. Por isso as experiências iniciais tornam-se fulcrais para uma aprendizagem significativa da álgebra. Assim, neste estudo, pretende-se estudar o impacte das várias tarefas aplicadas em sala de aula, quer individualmente, quer aos pares, ou em turma, a fim de se perceber o que, efetivamente, o aluno aprendeu das noções elementares da álgebra, mais concretamen te das equações. Com estas tarefas foi possível identificar algumas das dificuldades sentidas pelos alunos, neste ramo da matemática.

We developed this dissertation aiming its in the process of teaching and learning of the Principle of Mathematical Induction and we set our efforts so that the students of the first year of the high school can assimilate the content having the knowledge seen in the basic education as foreknowledge. With this, we seek to awake in the student the interest on proofs, showing how much it s needed in examples that involve contents that he is already seen

Generally, arithmetic and geometric progressions are taught separately from ane and exponential functions, only by the use of memorized formulas and without any concern of showing students how these contents are related. This paper aims at presenting a way of teaching such contents in an integrated way, starting with the definition of ane and exponential functions relating them to situations from the daily life of the students. Then, characteristics and graphics of those functions are presented and, subsequently, arithmetic and geometric progression are shown as a restriction of the ane and exponential functions. Thus, the study of the progressions is introduced based on the functions mentioned above using situations from students daily lives as examples

In this study, we sought to address the weaknesses faced by most students when they were studying trigonometric functions sine and cosine. For this, we proposed the use of software Geogebra in performing a sequence of activities about the content covered. The research was a qualitative approach based on observations of the activities performed by the students of 2nd year of high school IFRN - Campus Caicfio. The activities enabled check some diculties encountered by students, well as the interaction between them during the tasks. The results were satisfactory, since they indicate that the use of software contributed to a better understanding of these mathematical concepts studied

The objective of this work if constitutes in creation a proposal for activities, in the discipline of mathematics, for the 6th year of Elementary School, that stimulates the students the develop the learning of the content of fractions, from the awareness of the insufficiency of the natural numbers for solve several problems. Thus, we prepared a set with twelve activities, starting by the comparison between measures, presenting afterward some of the meanings of fractions and ending with the operations between fractions. For so much, use has been made of materials available for use in the classroom, of forma ludic, for resolution of challenges proposed. Through these activities, it becomes possible students to recognize the necessity of using fractions for solve a amount larger of problems

This thesis aims to show teachers and students in teaching and learning in a study of Probability High School, a subject that sharpens the perception and understanding of the phenomea of the random nature that surrounds us. The same aims do with people who are involved in this process understand basic ideas of probability and, when necessary, apply them in the real world. We seek to draw a matched between intuition and rigor and hope therebyto contribute to the work of the teacher in the classroom and the learning process of students, consolidating, deepening and expaning what they have learned in previous contents

The aim of this work is to provide a text to support interested in the main systems of amortization of the current market: Constant Amortization System (SAC) and French System, also known as Table Price. We will use spreadsheets to facilitate calculations involving handling exponential and decimal. Based on [12], we show that the parcels of the SAC become smaller than the French system after a certain period. Further then that, we did a comparison to show that the total amount paid by SAC is less than the French System
