A Colaboração na Formação de Professores que Ensinam Matemática Márcia Cristina de Costa Trindade Cyrino Educación Colaboração espaços formativos grupos colaborativos formação de professores que ensinam matemática A colaboração tem se destacado pelo seu potencial na formação de professores que ensinam matemática, por promover processos de interação entre professores, futuros professores, formadores, coordenadores, dentre outros agentes educacionais, e, por conseguinte, um ambiente de aprendizagem para todas as pessoas envolvidas nesses processos de interação. Esse número especial é constituído por nove artigos que podem contribuir para um debate qualificado a respeito dessas potencialidades e de dificuldades encontradas na busca de um ambiente colaborativo. 2021 editorial 2182-8474 https://www.redalyc.org/articulo.oa?id=575769046001 https://www.redalyc.org/journal/5757/575769046001/ https://www.redalyc.org/journal/5757/575769046001/html/ https://www.redalyc.org/journal/5757/575769046001/575769046001.epub https://www.redalyc.org/journal/5757/575769046001/movil 10.25749/sis.24924 pt http://www.redalyc.org/revista.oa?id=5757 Sisyphus — Journal of Education application/pdf Universidade de Lisboa Sisyphus — Journal of Education (Portugal) Num.2 Vol.9
