Lesson Study and their effects on teaching conversations

With the purpose of contributing to the understanding of the conversation processes that are deployed in the development of a methodology for teacher professional development; this study describes the conversation modalities that emerge in the collaborative planning processes of two language classes at the primary level, in the context of the implementation of Lesson Study. From the qualitative analysis of the complete turns of speech in the teacher exchanges and using Mercer's model of analysis of conversation modalities (1991), it is observed that the participating teachers move from a disputative and cumulative modality, to an exploratory modality, based on collaboration and critical analysis.
