Este trabajo examina discusiones de aula de un grupo de escolares de segundo curso de Educación Primaria implicados en una actividad de indagación experimental. Se han analizado de manera simultánea las preguntas de la docente y las operaciones epistémicas realizadas por las y los estudiantes. Nuestros resultados muestran que las preguntas productivas y las estrategias dialógicas utilizadas por la maestra son determinantes para promover las operaciones epistémicas vinculadas a la indagación. Además, la comparación con un grupo control que no participó en el diseño del experimento ni en las discusiones durante la indagación demuestra que el hecho de involucrar al alumnado en dichos procesos promueve que emerjan algunos aspectos de la naturaleza de la ciencia en el discurso de los niños y las niñas.

This essay studies the acting epistemological operations in current Argentinean poetic criticism, taking into account the theoretical-philosophical statement of its speech. For that purpose, it postulates an emerging tradition located in the last decades of the 20th century, from the constitution of a foundational work: the essay performed by Noé Jitrik entitled "Alturas de Machu Picchu. Una marcha piramidal a través de un discurso poético incesante". Afterwards, it was possible to see in two eminent critics of the next generation -Cristina Piña and Daniel Freidemberg- the coexistence of opposite trends regarding aesthetics elections, typical of the poetics of the sixties, and continued to the eighties, but with the common feature of productive processing of modern literary theory.

This essay studies the acting epistemological operations in current Argentinian critics of poetry, taking into account the theoretical-philosophical statement of its discourse. For that purpose, it postulates an emerging tradition located in the last decades of the 20th century, from the constitution of a foundational work: the essay by Noé Jitrik entitled "Alturas de Machu Picchu. Una marcha piramidal a través de un discurso poético incesante". Afterwards it was shown, by two eminent critics of the next generation —Cristina Piña and Daniel Freidemberg— the coexistence of opposite trends regarding aesthetics choices, typical of the poetics of the sixties, and continued to the eighties, but with the common feature, by the critics, of productive processing of modern literary theory.
