Fitting Lesson Study to the Portuguese Context

The adaptation of lesson study to different national contexts raises problems that are attracting the attention of researchers. In this chapter, we show how we have conducted lesson study in Portugal, taking into account the national educational context and our perspective on the teaching of mathematics, the exploratory mathematics curriculum approach, with particular attention on the development of students’ mathematical reasoning. We present two examples of lesson study, one conducted with in-service teachers of grades 5–6 and another in initial teacher education with prospective teachers of grades 7–12. We reflect on what we have identified as the main obstacles to the realization of lesson study in these contexts due to cultural factors and teachers’ concerns. We conclude with a summary of the adaptations that we have made in this teacher education process, with a view to the suitability and potential of lesson study in our country.

Teachers’ involvement and learning in a lesson study

The aim of this study is to analyse the way a group of basic education teachers got involved in a lesson study and their views, as they discuss the features of tasks, students’ expected difficulties and how to conduct exploratory work in the mathematics classroom. The conceptual framework draws on notions of task design and considers the features of lesson study. Data collection was made through a research journal made by one of the authors in the role of observer, video recording with transcription of the sessions, teachers’ written reflections and interviews. The results underscore the value of focusing on students’ reasoning in working in mathematical tasks as well as the need to address affective issues, regarding the way teachers are invited to become involved and participate in lesson studies.

Que historia, para qual cidadania? O ensino de historia na educacao basica no Mexico No Mexico a reflexao acerca dos vinculos entre a historia como disciplina escolar e os processos sociais de construcao de cidadania, requer conceber este objeto de estudo como apenas uma parte de um processo muito mais complexo que o vincula tanto a educacao civica e etica, como as praticas cotidianas conformadoras de uma certa cultura escolar. E necessario situar historicamente as origens e formas de funcionamento de cada uma dessas facetas, assim como a maneira em que entre elas se reforcam em suas pretensoes formativas. Somente desse modo e possivel reconhecer os fins, utilidades e limites do ensino de historia tal qual e concebido hoje em dia, assim como sua impossibilidade de assumir como objetivos educativos a construcao de nocoes democraticas referidas a uma concepcao moderna de cidadania. Palavras-chave: Cidadania. Historia e seu ensino. Formacao para a democracia. Resumen En Mexico la reflexion acerca de los vinculos entre la historia como disciplina escolar y los procesos sociales de construccion de ciudadania, requiere concebir este objeto de estudio como solo una parte de un proceso mucho mas complejo que lo vincula tanto a la educacion civica y etica, como a las practicas cotidianas conformadoras de una cierta cultura escolar. Es necesario ubicar historicamente los origenes y formas de funcionamiento de cada una de esas facetas, asi como la manera en que entre ellas se refuerzan en sus afanes formativos. Solo de esa forma es posible reconocer los fines, utilidades y limites de la ensenanza de la historia tal cual es concebida hoy en dia, asi como su imposibilidad de asumir como objetivos educativos la construccion de nociones democraticas referidas a una concepcion moderna de ciudadania. Palabras claves: Ciudadania. Historia y su ensenanza. Formacion para la democracia. Abstract Which history, to which citizens? History teaching in basic education in Mexico In Mexico, a reflection on the links between History as a school subject and the processes of social construction of citizenship requires conceiving the object of study as only part of a much more complex process that binds it both to civic education and ethics, and to everyday forming practices of a certain school culture. It is necessary to historically locate the sources and forms of operation of each of these facets as well as the way they reinforce their training claims.Only in this way it is possible to recognize purposes, uses and limits of teaching History as it is conceived today, as well as its inability to take as an educational goalthe building of democratic notions related to a modern conception of citizenship. Keywords: Citizenship. History and its teaching. Training for democracy.Resumen En este trabajo se evaluan algunos elementos del conocimiento matematico comun y especializado del contenido y del conocimiento del contenido y los estudiantes en relacion con la probabilidad elemental en una muestra de profesores en formacion. El conocimiento comun del contenido se evalua a partir de las soluciones de 157 profesores en formacion a tres problemas. Una vez discutidas con los participantes estas soluciones, se analizan dos componentes del conocimiento de 81 de ellos, trabajando en pequenos grupos: (a) El conocimiento especializado del contenido se evalua a partir de los contenidos matematicos identificados en los problemas; (b) el conocimiento del contenido y los estudiantes a partir de la identificacion y justificacion de respuestas de alumnos de educacion primaria. Aunque en la evaluacion inicial se observo un bajo razonamiento probabilistico, en la segunda los participantes son capaces de identificar y explicar las respuestas incorrectas de los alumnos.

Abstract Normal 0 21 false false false PT-BR X-NONE X-NONE MicrosoftInternetExplorer4 Prospective primary school teachers’ mathematical knowledge for teaching probability: an exploratory study This study assesses some elements of common and specialized mathematical knowledge and of knowledge of content and students in relation to elementary probability from a sample of prospective primary school teachers. Common knowledge of content is assessed from the individual solution of 157 prospective teachers to three problems. Once the solution to these problems was discussed with the participants, two additional components of these teachers’ mathematical knowledge for teaching were analyzed based on small group work developed by 81 participants: (1) To assess specialized knowledge of content we asked participants to identify the tasks mathematical content; (b) to assess their knowledge of content and students we asked them to identify and justify correct and incorrect answers to the problems given by primary school children. While in the initial assessment we observed a poor probabilistic reasoning, in the second part they were able to identify and explain incorrect answers given by students.

O artigo pontua, tambem, que a formacao de estudiosos e de profissionais da educacao tem, como tarefa principal, a consolidacao do habito intelectual de sensibilidade e de criatividade diante de qualquer manifestacao da vida humana, tal como aflora nos varios processos culturais, na diversidade e na complexidade de cada um deles, na concreticidade das praticas sociais que os engendram.

Abstract Meaning of knowledge production in Postgraduate studies and its communication with social practices This paper highlights the need, which a Postgraduate Programme in Education may have, of producing knowledge from a continuous effort of integral human experience openness, not closing itself to narrow epistemological positions of that experience. This paper also enphasizes that the education of scholars and education professionals has as main task the consolidation of the intellectual habit of being creative and sensitive towards any manifestation of human life, just as it emerges in various cultural processes, in the diversity and complexity of each one of them and in the reality of social practices that give birth to them.
