RESUMEN En el ámbito de la didáctica de las ciencias se evidencian cada vez más trabajos científicos enfocados en las ideas previas de los estudiantes por su relevancia e influencia a la hora de afrontar la enseñanza-aprendizaje en el aula. Apoyando esta idea, este artículo muestra los resultados obtenidos del instrumento de recolección de información aquí denominado "mitos y realidades", dicho instrumento se empleó en la fase preliminar de una investigación que busca la articulación del Proyecto Pedagógico Productivo Huerta Escolar con la construcción del concepto ecosistema en una escuela rural de Bogotá. El objetivo de dicho instrumento fue indagar las ideas previas de los estudiantes, a su vez, las respuestas obtenidas se organizaron en dos grandes categorías de análisis¨diversidad análisis¨diversidad e interacciones¨. El análisis permite establecer que, uno de los aportes de la huerta escolar en la construcción del concepto ecosistema es ubicar al estudiante en una transición entre el nivel de progresión de concepción aditiva del ecosistema y el ecosistema como organización simple, propuestas por García, 2003, además se concluye que el escenario huerta escolar fortalece la observación e integración del mesocosmos en la construcción del concepto ecosistema. ABSTRACT In the field of didactics of science, there is an increasing evidence of scientific work focusing on students' previous ideas because of their relevance and influence when facing teaching-learning in the classroom. Supporting this idea, this article shows the results obtained from the information gathering instrument here named "myths and realities"; this instrument was used in the preliminary phase of an investigation that seeks the articulation 1 Estudiante de licenciatura en biología, Universidad Distrital Francisco Josè de Caldas, angiemartinez.
This article reveals the interplay between assessment policies in Uruguay and the nature of State-societal relations. The central State has been historically a staunch defender of public education and has championed the cause of equalizing opportunities for the most disadvantaged sectors of society. The national evaluation system of student performance has been constructed as an expression of this tradition. The Uruguayan government sought to build a wide level of consensus with respect to the assessment instruments by encouraging educators to participate and buy into the assessment initiative. Moreover, the national government shifted the focus of the national evaluation from measuring schooling outcomes to addressing the social wants that condition student learning. Hence, the national evaluation has come to symbolize an agreed-upon mechanism of social accountability by which the central government upholds its responsibility for educational provision as it intervenes on behalf of impoverished communities.
