Experiencias en investigación-acción con educadores en proceso de formación en Colombia José Federman Muñoz Giraldo Josefina Quintero Corzo Raúl Ancízar Munévar Molina Educación acción investigación práctica educativa Formación inicial del profesorado Este artículo presenta procesos y resultados de las experiencias llevadas a cabo por ungrupo de profesores y alumnos en programas de formación de educadores en la Universidad de Caldas (Colombia). El propósito del artículo consiste en presentar losresultados de un proceso de asesoría a educadores en proceso de formación durante susprácticas en colegios oficiales, aplicando los ciclos de la investigación-acción-reflexión. Laparticipación, el trabajo colaborativo, la toma de decisiones y la reflexión crítica de laacción son evidencias que permiten demostrar cómo un educador en proceso deformación aprende a investigar mientras está aprendiendo a enseñar. 2002 artículo científico 1607-4041 https://www.redalyc.org/articulo.oa?id=15504104 es http://www.redalyc.org/revista.oa?id=155 REDIE.
