Validation of a Scale of Interaction in Virtual Learning Environments
Abstract
Various studies have pointed to the importance of interaction between the actors (teacher-student) in virtual learning environments. In this paper our objective is to evaluate the dimensions of interaction of distance-learning students in virtual learning environments. A Scale of Interaction in Virtual Learning Environments was constructed, based on Barberà, Badia and Monimó’s (2001) interaction typology. Assessment by expert judges was used to improve content validity. Subsequently the scale was applied to a sample of distance-learning high school students in order to identify psychometric properties. The scale had a reliability coefficient of .93 and the following factorial structure: Factor I) Learning support interactions with the advisor; Factor II) Interactions with the virtual environment learning materials; and Factor III) Dialogic interaction with peers. This measurement model was evaluated by means of CFA, which demonstrated adequate goodness-of-fit indices.
