Com base num estudo de caso, procuramos compreender em que medida a participação de uma professora em estudos de aula tem reflexos na sua prática letiva. A recolha de dados incluiu observação participante (com realização de diário de bordo e gravações áudio/vídeo), recolha documental (tarefas e planos de aula) e entrevista. Os resultados indicam que participar em estudos de aula, planeando discussões coletivas a partir das respostas dos alunos, contribuiu para mudanças na prática da professora. Ela propôs uma tarefa que permitiu aos alunos estabelecerem conexões entre representações, e, na discussão coletiva, incentivou a participação de vários alunos e desafiou-os a ir além da tarefa, o que não fez nos estudos de aula.
在个案研究的基础上,我们试图了解教师参与课堂学习在多大程度上反映了她的教学实践。数据收集包括参与者观察(包括日志和音频/视频记录)、文献收集(任务和课程计划)和访谈。结果表明,参与课堂学习,根据学生的反应计划集体讨论,有助于教师实践的改变。她提出了一个任务,让学生在表现之间建立联系,在集体讨论中,鼓励几个学生的参与,并挑战他们超越任务,这是他们在课堂学习中没有做的。

This investigation explores the combination of Instrumental Meta-Orchestration (IMO) and the Lesson Study methodology (LS) in teacher training. Under the Theory of Instrumental Orchestration (IO) and the knowledge domains of Ball and colleagues, and of Koehler and Mishra, the knowledge mobilized by mathematics undergraduates from a Brazilian public university was analyzed following a research-action-training design. The results indicate the relevance of combining the IMO and the LS to foster both future teachers’ development on mathematics topics and their knowledge on preparing and implementing an IO.
本研究探讨了器乐元编曲(IMO)与课程研究方法论(LS)在教师培训中的结合。在器乐编曲理论和Ball等人、Koehler和Mishra等人的知识领域的指导下,采用研究-行动-训练设计对巴西某公立大学数学专业本科生的知识动员进行了分析。研究结果表明,将国际教学组织与外语教学组织结合起来,既有助于培养未来教师在数学主题方面的发展,也有助于培养他们在准备和实施国际教学组织方面的知识。

Se analiza la presencia de los procesos matemáticos en libros de texto de Educación Infantil de Chile y España. Para ello, se ha realizado un análisis de contenido de las tareas matemáticas de: números, geometría, medida, álgebra, estadística y probabilidad. Los resultados muestran un predominio de los procesos de resolución de problemas y representación. Los procesos matemáticos menos presentes son: comunicación y razonamiento y prueba. Por otro lado, se observa el rol trascendental de la guía didáctica del docente al ofrecer sugerencias para la gestión de las tareas orientadas a ofrecer oportunidades de aprendizaje vinculadas con los procesos matemáticos.
本文分析了智利和西班牙儿童教育教科书中数学过程的存在。为此,对数学任务进行了内容分析:数字、几何、测量、代数、统计学和概率。结果表明,问题解决和表征过程占主导地位。最不常见的数学过程是:沟通、推理和证明。此外,我们还观察到教师的教学指南在为任务管理提供建议方面的重要作用,这些建议旨在提供与数学过程相关的学习机会。

Figural patterns have a unique capacity to promote functional thinking. This study aimed to identify the mental constructs of 7th-grade students in Figural Pattern Generalization (FPG) by using the Action, Process, Object, Schema (APOS) theory in order to develop a framework for evaluating students' understanding of FPG. A sample of 220 students completed a test designed based on the APOS framework and 19 students participated in a semi-structured interview. Results showed that there are emergent and partial action levels before the action stage and pre-emergent, and partial process/object levels before the process/object stage.
图形模式具有促进功能思维的独特能力。本研究旨在运用动作-过程-对象-图式(APOS)理论,识别七年级学生在图形模式概括(FPG)中的心理构念,以建立一个评估学生对图形模式概括理解的框架。220名学生完成了基于APOS框架设计的测试,19名学生参加了半结构化访谈。结果表明,在动作阶段和前反应阶段前存在着紧急和部分动作水平,在过程/对象阶段前存在着部分过程/对象水平。
