Resumo O texto analisa os saberes docentes mobilizados pelos professores dos cursos de Licenciatura em Ciências Naturais e Matemática na modalidade de educação a distância (EAD) nos Institutos Federais (IF) de Educação, Ciência e Tecnologia. O método de investigação, fenomenológico, estruturou-se em três etapas. Na primeira etapa foram localizados, entre todos os IF do Brasil, os que possuíam cursos de Licenciatura em Ciências Naturais e Matemática na modalidade de EAD. Na segunda etapa, foram analisados seus ordenamentos institucionais. E, na terceira etapa, por meio da análise ideográfica e nomotética, buscou-se identificar elementos para elucidar os saberes docentes no contexto das licenciaturas nos IF. Considerou-se que os saberes oriundos da profissionalização docente são frutos de formação inicial e continuada, consciente, ética, crítica e pautada em trajetórias que reflitam continuamente sobre o processo de formação, sobre o espaço de trabalho e sobre o mundo desejado para si e para os outros.

Abstract This paper analyzes the teaching knowledge used by professors of Natural Sciences and Mathematics distance education degree undergraduate programs at Federal Institutes (FI) of Education, Science and Technology. The method of investigation, phenomenologically, was structured in three phases. In the first step, there was the identification, among all the Institutes in Brazil, among those that offer the Natural Sciences and Mathematics in the distance education mode. The second step involved the analysis and institutional framework of the Institutes. And in the last stage, through the ideographic and nomothetic analyses, there was the identification of elements to enlighten the teaching knowledge in the context of the degree courses at FI. It was considered that the teaching knowledge coming from the teaching profession is a result of an initial and consciously continued formation, which is also ethical and critical and which is guided by trajectories that continuously reflect upon the process of teaching formation, upon the work space and upon the desired world for the professor and for others.

This is a case study on the reading and writing practices of six year old children engaged in the daily use of digital technology, conducted in a public school in Porto Alegre (RS/Brazil) and made possible by the One Laptop per Child (OLPC) project. Its aim was to investigate the practices carried out by students and the possibilities and conditions under which the computer can become a tool that enables them to enter the "literate world". The students' practices were examined based on three units of analysis: practices proposed by a teacher, spontaneous practices and representative cases. These practices were categorized into three areas: literacy, fluency of written language and technological fluency. The research began with a theoretical proposal that had to be modified as a result of the study, and emphasizes the importance of pedagogical proposals for children in the initial process of written language learning.

Estudio de caso sobre las prácticas de lectura y escritura de niños de seis años de una escuela pública de Porto Alegre (RS / Brasil), inmerso en la cotidianidad digital, lo que hace viable el proyecto de una computadora por Niño. El objetivo fue investigar las prácticas realizadas por los estudiantes, así como las posibilidades y condiciones necesarias para que la computadora sea una herramienta para que puedan entrar en el "mundo alfabetizado". Las prácticas de los estudiantes fueron examinadas en tres ejes de análisis: prácticas propuestas por el profesor, las realizadas de manera espontánea y los casos emblemáticos; esas prácticas se clasificaron en tres ejes: alfabetización, fluidez de la lengua escrita y fluidez tecnológica. La investigación inició con una propuesta teórica que tuvo que ser modificada como resultado del estudio, haciendo hincapié en la importancia de las propuestas pedagógicas para los niños en el proceso inicial de aprendizaje de la lengua escrita.
