Functionality of feedback in pedagogical processes has been broadly analyzed in face-to-face learning, although to a lesser extent than in the on-line learning. Narciss (2004, 2008) distinguishes two dimensions within the feedback, the semantic dimension and the structural dimension. This article aims to analyze, from the student's perspective, the semantic dimension of feedback in a virtual learning environment (VLE). Firstly, we analyze the importance that VLE students give to feedback and its degree of personalization. Later, the usefulness that students deem feedback should have, paying special attention to each of its semantic subdimensions (Narciss, 2004).
