Metodologia de ensino do conceito de função exponencial à luz da teoria das situações didáticas

This essay presents a proposal on methodology over the mathematical object Exponential Function which enables the development of interpretative and creative skills with potential meaning to the students starting from a didactic sequence structured on the light of The Theory of Didactic Situations from Guy Brousseau and, from the Records of Semiotic Representation of Duval, providing interactions among the students, the teacher and the environment of cooperative learning where the students feel free to express their own ideas as well as to suggest their own approaches. The methodology presented has been developed according to the students first knowledge, valuing their different ways of registering, which have such an important role during the teaching and learning processes. The proposal has been applied to the students from the first year of high school of Colégio Estadual José de Anchieta Ensino Fundamental e Médio, located in a town called Dois Vizinhos –Paraná. In order to the development of the research the methodological tool Didactic Engineering Artigue which consists in a methodology developed only to the research with didactic situations. The main goal has been reached at first, which was to work on the conceptual part of the Exponential Function, the relation of dependence and its main characteristic so that the variable part is in the exponent. Moreover with no imposition but starting from suitable didactic situations, the students were able to realize that they could solve the problems which involve the exponential function and furthermore create new problems (according to their universe) modeled by this kind of function. Its believed that the methodology based on the theory of didactic situations, analysis of students registers, observation on mistakes and obstacles as well as reflections over the aspects of the didactic contract are of fundamental importance to the teaching practice and determinant during the teaching-learning process.

Concepções de interdisciplinaridade: o Programa Ensino Médio Inovador

The Interdisciplinary practice opens in the context of Basic Education guiding new looks in the production of knowledge. It is necessary to reflect the interdisciplinarity as scientific and epistemological stance and its conditions of possibility of expanding the horizon before the theoretical and methodological challenges posed by modernity. Thus, this work aimed to analyze interdisciplinary concepts present in the proposal of the High School Program Innovator. Therefore, the theoretical route initially had the search for understanding of high school in Brazil, interdisciplinarity as the possibility of tensioning the production of scientific knowledge, mainly anchored in the studies of Acácia Kuenzer, Dermeval Saviani, Boaventura de Sousa Santos, Claude Raynaut, Henrique Leff and Edgar Morin. The study was methodological subsidy document research and principles of content analysis. The analysis took place from the seven documents that make up the construction path of High School Program Innovator and a semi-structured interview. So, we sought to understand the concepts of the documents establishing analytical categories from more evoked content. In this process identified three categories with regard to the construction of the Program proposal: pedagogical innovations, curriculum organization and teaching quality and three categories with regard to interdisciplinary concepts present in the program: dialogue between curriculum components, joint knowledge and role of high school students. From the studies it was observed that the program came up with the prospect of directing a new identity for the final stage of basic education, listing Documents Guiding Plans and actions for a new curricular organization of secondary education. It was noted that the Program, though explicit in its guiding documents of the interdisciplinary perspective, in no time he calls himself as interdisciplinary. Interdisciplinary actions should run or from school understanding, as well as the preparation of the Redesign Project Curriculum encompassing dialogue between disciplines. Realized by the analysis of the guiding documents is a back program even for a technical rationality practiced by the particular understanding of the school and the practice being expressed from the same concepts that high school is developed, with each teacher teaching the contents of their disciplines and performing cross designs. Break the existing paradigm is still one of the challenges to the teaching-learning process. Break the existing paradigm is still one of the challenges to the teaching-learning process.

Demonstração de fórmulas matemáticas no ensino médio

The objective of this study is to analyze the validity of working with proofs in the classroom and to present a partial list of proofs of mathematical formulae of the Brazilian secondary/high school curriculum. The adaptation of the proofs into the knowledge and abilities of a secondary school student should also be considered. How the teaching of proofs is treated in official publications in Brazil and other countries is also described. Working with proofs provides a number of benefits to the students, including: the development of logical reasoning, argumentative capacity, analytical skills on a daily basis, as well as motivation and a better understanding of mathematics as a science. The convenience of including the teaching of proofs in Brazilian secondary school curriculum and the need of a balance between the abstraction of proofs and contextualization of the school programmes is discussed. The approach of the proof teaching in the classroom can become a motivating factor or, conversely, a discouraging one. The conclusion is that it would be very useful to create a reference list covering the mathematical expressions of school programmes with their respective proofs that can be understood by secondary school students.
