Alcances para una Conceptualización Constructivista del Concepto de Acción Social Rodrigo Flores Guerrero Filosofía Acción social Epistemología Constructivismo Estudios sociales Estudios culturales El acusado interés por el conocimiento y explicación de los fenómenos humanos .y posteriormente por las formas instauradas y mayormente validadas de conocimiento occidental, como es la ciencia y en especial las ciencias sociales, ha llevado a la proposición de múltiples definiciones y conceptualizaciones acerca de los acontecimientos que cotidianamente vivimos. La misma diferenciación interna y especialización temática de las disciplinas que se dedican al estudio de lo sociocultural, unido al aumento considerable de complejidad en su objeto de estudio, con el transcurrir del tiempo ha llevado a la revisión y reformulación de muchas de las definiciones y conceptos que se daban por conocidos y aceptados. Ante ello no es difícil identificar diferentes formulaciones explicativas que pueden ser enmarcadas de acuerdo al desarrollo de diferentes epistemologías. 1997 artículo científico 0717-554X https://www.redalyc.org/articulo.oa?id=10100209 es http://www.redalyc.org/revista.oa?id=101 Cinta de Moebio application/pdf Universidad de Chile Cinta de Moebio (Chile) Num.2
