Firstly, was made an analysis of the introduction of the concept of limit in Calculus textbooks, based on the theoretical framework. Then, a mapping of articles on the ideas of David Tall was done, as well as a search of dissertations and theses that were based on these ideas. In the last phase, a test on limits of functions was applied to students of mathematics teaching courses, who had already studied the discipline of Calculus I and were interviewed professors of this discipline in both courses. The analysis of the textbooks made it possible to verify that, in the introductory chapters, there is a work that advocates features of the symbolic and embodied worlds, especially the first, with some aspects of the formal world. In relation to the interviews with the teachers, they affirmed that begin with graphical examples and tables of functions values to introduce the concept and only then try to reach the formal definition, crossing the Three Worlds of Mathematics. In the test applied to the students, it was concluded that most of them use the natural language to conceptualize limit, presenting characteristics of the embodied world, with some symbolic elements, but without achieving a development compatible with the formal axiomatic world. / Esta pesquisa, de caráter qualitativo, tem como objetivo geral analisar o conceito de limite de uma função em um ponto, apresentado por estudantes de dois cursos de Licenciatura em Matemática, bem como suas estratégias de resolução de questões, à luz da Teoria dos Três Mundos da Matemática. Primeiramente, foi realizada uma análise da introdução do conceito de limite em livros didáticos de Cálculo, com base no quadro teórico. Em seguida, foi feito um mapeamento de artigos sobre as ideias de David Tall, bem como uma busca de dissertações e teses que se basearam nessas ideias. Na última etapa, foi aplicado um teste sobre limites de funções a alunos que já haviam cursado a disciplina de Cálculo I e foram entrevistados docentes dessa disciplina nos dois cursos. A análise dos livros didáticos possibilitou verificar que, nos capítulos introdutórios, há um trabalho que preconiza características dos Mundos Simbólico e Corporificado, especialmente do primeiro, com alguns aspectos do Mundo Formal. Em relação às entrevistas com os professores, estes declararam partir de exemplos gráficos e tabelas de valores de função para introduzir o conceito e só depois tentam chegar à definição formal, perpassando os Três Mundos da Matemática. Em se tratando do teste aplicado aos estudantes, concluiu-se que a maior parte dos alunos utiliza a linguagem natural para conceituar limite, apresentando características do Mundo Corporificado, com alguns elementos simbólicos, mas sem atingir um desenvolvimento compatível com o Mundo Axiomático Formal.

Considering that the textbook is the material with which the teacher has more contact, start with reading historical texts present in these books. Choose a theme and choose from that we observed limitations ranging from the search for sources of research in relation to the actual historical content. There are many studies that show the importance of the history of mathematics in teacher education and also in the teaching and learning of mathematics. These works , in particular the work of Feliciano (2008 ) entitled : " The use of history of mathematics in the classroom " , along with the information , experiences and opinions given by Professor Anderson Lu?s de Azevedo Paulo , in some meetings , point to need for materials for teaching , since they show that recognizes the importance of this knowledge and the ability to use it in the classroom , but several factors have pushed aside , even the texts present in textbooks. From the analysis of some of the work and contributions of Professor Anderson Paulo we pointed out some of the factors that make historical texts being ignored by teachers and among them are characteristics in appearance and content in the text. To assist in the preparation of materials that meet the expectations of the teacher, we present a manual with suggestions and / or features to choose or produce a good text. These suggestions can make the history books more enjoyable and thus approach the teacher of historical knowledge and later encouraged to seek, in fact, a historical formation / Este trabalho ? resultado de um estudo que teve como objetivo inicial pontuar dificuldades que o professor de matem?tica encontra ao tentar buscar uma forma??o hist?rica. Tendo em vista que o livro did?tico ? o material com o qual o professor tem mais contato, come?amos com a leitura de textos hist?ricos presentes nesses livros. Escolhemos um tema e a partir dessa escolha pudemos verificar limita??es que v?o desde a busca por fontes de pesquisa at? em rela??o ao pr?prio conte?do hist?rico. Muitos s?o os trabalhos que mostram a import?ncia da Hist?ria da Matem?tica na forma??o do professor e tamb?m no processo de ensinoaprendizagem de Matem?tica. Esses trabalhos, em especial o trabalho de Feliciano (2008) intitulado: O uso da Hist?ria da matem?tica em sala de aula , juntamente com as informa??es, experi?ncias e opini?es dadas pelo professor Anderson Lu?s de Azevedo Paulo, em alguns encontros, apontam a necessidade de materiais para o docente, pois mostram que reconhece a import?ncia desse conhecimento e a possibilidade de us?-lo em sala de aula, mas por diversos fatores tem deixado de lado, at? mesmo os textos presentes nos livros did?ticos. A partir da an?lise de alguns trabalhos e das contribui??es do professor Anderson Paulo pontuamos alguns dos fatores que fazem os textos hist?ricos serem ignorados pelos professores e entre eles est?o caracter?sticas na apar?ncia e no conte?do presente no texto. Para ajudar na elabora??o de materiais que atendam ?s expectativas do professor, apresentamos um manual com sugest?es e/ou caracter?sticas para escolha ou produ??o de um bom texto. Essas sugest?es podem deixar os textos de hist?ria mais agrad?veis e assim aproximar o professor do conhecimento hist?rico e posteriormente incentivado a buscar, de fato, uma forma??o hist?rica

The author shares some of the findings of the research he conducted in 2007 on grade 11 mathematics learners in two schools, one experimental and the other one control. In his study, the author claims that an open-ended approach towards teaching and learning of mathematics enhances understanding of mathematics by the learners. The outcomes of the study can be summarised as follows: 1. In the experimental school, where the author intervened by introducing an open-ended approach to teaching mathematics (by means of giving the learners an open-ended approach compliant worksheet to work on throughout the intervention period), the performance of the learners in the post-test was better than that of the learners from the control school. Both schools were of similar performance in the pre-test. The two schools wrote the same pre-test and same post-test. Both schools were following common work schedule. 2. Within the experimental school, post-test performance of the learners in the class where the intervention was monitored throughout the intervention period (thus ensuring compliance of the teacher to the open-ended approach) out-performed those in which monitoring was less frequent. 3. There was no significant difference in performance between learners from the unmonitored experimental class and those from the control class.
