Efectos de las bases de conocimiento hipertextuales semánticamente estructuradas en las estructuras de conocimiento de los usuarios

David H. Jonassen

Resumen


Algunos investigadores y diseñadores de hipertextos creen que las estructuras de información de los hipertextos deberían reflejar las estructuras de la memoria humana y que, al derivar empíricamente y cartografiar la estructura semántica de la información sobre el hipertexto, y al ilustrar explícitamente esa estructura en la interfaz hipertextual, se efectuarán mayores cambios en las estructuras de conocimiento de los usuarios (Jonassen, 1990, 1991b; Lambiotte et al., 1989; McAleese, 1990; McDonald, Paap y McDonald, 1990). Este capítulo presenta técnicas para averiguar la estructura del conocimiento de un experto y organizarla en un hipertexto. Después, se analizarán los resultados de una serie de estudios en curso que comprueban dichas ideas. Estos estudios muestran que el mero hecho de representar las estructuras de contenido en la interfaz no es suficiente para ayudar a los estudiantes a adquirir dicha estructura. Son la naturaleza de la tarea de procesamiento y los objetivos de aprendizaje al interactuar con un hipertexto los que en realidad determinan los efectos de su uso en las estructuras de conocimiento de los estudiantes.
