Uma análise dos questionamentos dos alunos nas aulas de números complexos

This work presents a contribution for the studies reffering to the use of the History of Mathematics focusing on the improvement of the Teaching and Learning Process. It considers that the History of Matematics, as a way of giving meaning to the discipline and improve the quality of the Teaching and Learning Process. This research focuses on the questions of the students, classified in three categories of whys: the chronological, the logical and the pedagogical ones. Therefore, it is investigated the teaching of the Complex Numbers, from the questions of the students of the Centro Federal de Educação Tecnológica do Rio Grande do Norte (Educational Institution of Professional and Technology Education from Rio Grande do Norte). The work has the following goals: To classify and to analyse the questions of the students about the Complex Numbers in the classes of second grade of the High School, and to collate with the pointed categories used by Jones; To disccus what are the possible guidings that teachers of Mathematics can give to these questions; To present the resources needed to give support to the teacher in all things involving the History of Mathematics. Finally, to present a bibliographic research, trying to reveal supporting material to the teacher, with contents that articulate the Teaching of Mathematics with the History of Mathematics. It was found that the questionings of the pupils reffers more to the pedagogical whys, and the didatic books little contemplate other aspects of the history and little say about the sprouting and the evolution of methods of calculations used by us as well

A leitura e a produção textual no ensino fundamental I: uma proposta de como trabalhar com os gêneros textuais

The little interest in reading and the large presence of deviations in writing observed in the texts of students of the 5th grade of a public school in RN, led us to question the motives of this problem. Thus, the idea to organize and develop teaching sequences with a variety of possibilities of reading and production through the text genres. The practice with the textual genres in elementary school extends the use of reading and writing and improves the quality of learning. In this way, the school, as one of the most active spheres in social practices of the language, we justify this work with the use of text genres as facilitators for teaching and learning the mother tongue. For this purpose, we draw as the main objective to talk about the work with textual genres from the development of didactic sequences, as well as encourage students to take a more reflexive attitude toward language and its uses, as discursive social practices. The development of the study with the text genres was made through the application of didactic sequences in the school context of elementary school classes, from 5th grade. Specifically were chosen, the letter, note, music, poetry, fable and the tale. The study is anchored in the reflections of the following theorists and researchers: Bakhtin (2011), Miller (1994), Marcuschi (2008) and Bronckart (1999) on the text genres; Marcuschi (2005) and Dolz and Schneuwly (2004) that approve a teaching-learning proposal focused on textual genres, giving a meaning to language in the construction of the knowledge and Dolz and Schneuwly (2004) regarding the didactic sequence; other theoretical orientations: PCN (1998), Lerner (2005), among others. The methodology followed the action research guidelines, in a qualitative approach perspective. The instruments of research included questionnaire, observations, readings and productions. The results pointed the students' interest in relation to the activities developed in the didactic sequences and consequently improvement in the students‘ own writings. In this sense, we reiterate the need to contamplate in the teaching activities the diversity of texts and genres and, not only due to its social relevance, therefore the student should be able to use the language in various way and adapt their texts to situations of oral and written interlocution.
