In order to make clear the social impacts of the digital education technologies, the essay offers a reflection about the ...

    • Valoración del desarrollo conceptual y de las habilidades procedimentales y de razonamiento en estudiantes del curso de tecnología de cereales en UNAD pasto, con la utilización como mediador didáctico de un simulador en procesos de panificación 

      Ortiz, Fedra Lorena; Álava, Clemencia; Argoty, Magali; Fernández, Pablo (Sello Editorial UNAD, 2009-04-10)
      The learning strategies have been applied in the past years in different educational contexts; several studies show that when they are put in use, the students improve their learning. On the other hand, with the development of new technologies, the virtual learning objects have been presented as an alternative for the development of cognitive abilities. Nonetheless, Carreras (2003) affirms that these kinds of objects ...

    • Diseño de una prueba para medir el uso de estrategias metacognoscitivas en un entorno virtual de aprendizaje 

      Landazábal Cuervo, Diana Patricia; Urrutia Sarmiento, Iván Eduardo (Sello Editorial UNAD, 2009-04-10)
      This research had the goal of developing the first phase of a one macro project.

The first it was to design and to validate the content of the test whit four experts judges. The test had 111 items in which we used the Mateo’s (1985) model. That model ...

    • El modelado y simulación para la comprensión de los sistemas de producción de pozos petroleros 

      Pineda Ballesteros, Eliécer; Calvete González, Fernando Enrique; Ruiz Díaz, Fernando (Sello Editorial UNAD, 2009-04-10)
      This article shows the results of a research proposal regarding if the use of models and simulations can contribute to the comprehension of the physical phenomenon associated with the production of oil wells. The research entails the modeling of the phenomena, including the oilfield and well. The Darcy Law is taken a theoretical reference, and once the models of the phenomena are built, a microworld is reconstructed ...
