Resumo
No ensino da matemática um dos assuntos mais desa adores aos alunos do Ensino Médio é o de funções exponenciais e logarítmicas, sendo que grande parte dos alunos possuem difi culdades de compreensão e resolução dos exercícios propostos. Dessa maneira o trabalho em tela tem como objetivo precípuo o ensino de funções exponenciais e logarítmicas, visando apresentar aos docentes a possibilidade de ensinar o conteúdo de maneira mais atrativa e acessível aos seus alunos. Para tanto, a pesquisa se valeu de levantamento bibliográ fico e documental acerca da temática abordada. Salienta-se que ao iniciar o ensino de funções é preciso fazer um resgate histórico do conteúdo, buscando desvelar suas origens. Posteriormente o trabalho traz as concepções do tema segundo os documentos o ciais. A m de concretizar o estudo trabalha-se com o uso das defi nições aritméticas e geométricas, pois são fundamentais para o entendimento das funções, e também com situações problema contextualizadas, buscando envolver os alunos no processo de ensino aprendizagem promovendo o levantamento de hipóteses e consolidando a aprendizagem. Essas situações problemas serão difundidas por meio de atividades propostas nas quais pretende-se explorar a caracterização da função logarítmica e exponencial, buscando relacioná-las ao contexto do educando, em situações que poderiam ocorrer em seu cotidiano, para isso propomos alguns exemplos de atividades, como: a utilização do BRO ce Calc no Ensino de potenciação com números irracionais, o jogo de xadrez, mágica do baralho e a resolução de problemas da OBMEP e do ENEM.
In teaching mathematics one of most challenging subjects to middle school students is of exponential and logarithmic functions, being that most of the students have difficulties in understanding and addressing the proposed exercises. In this way the work on canvas aims foremost teaching of exponential and logarithmic functions, n order to present to teachers the possibility to teach the content more attractive and accessible to his students. To this end, the research used for bibliographical and documental about the theme addressed.It should be noted that the starting teaching duties must make a historic rescue of the contents, looking for their origins unveiling. In order to implement the study works with the use of arithmetic and geometric definitions, because they are fundamental to the understanding of the functions, and also with contextualized problem situations, seeking to engage students in teaching learning process promoting the survey of hypotheses and consolidating learning. These problems will be disseminated through activities in which it is intended to explore the characterization of logarithmic and exponential function, seeking to relate them to the context of educating, in situations that could occur in their daily lives, for this we propose some examples of activities, such as: libreoffice Calc use in teaching empowerment with irrational numbers, the game of chess, magic of the deck and the troubleshooting of OBMEP and ENEM.
