The use of skill frameworks has become commonplace in the field of digital literacy. These frameworks are based preferentially on conceptual approaches, which leads to biases when applied in practice. Here, we present a study with an alternate focus: the skills proposed in the frameworks are connected with user behavior and heuristics are employed to group these skills. The objectives of the study were to: (1) achieve a greater coherence between the skills incorporated in these frameworks and user behavior, and (2) identify and reliably organize the clusters of skills that form frameworks. The study consisted of collecting data from a group of students about their practices within the skills of the Mozilla Web Literacy Map. The data was then grouped via factor analysis. The results were then contrasted with the initial organization of the Mozilla framework. The gap between the theoretical definition of a skill and individual behaviors was found to be more pronounced in the case of those skills whose definitions included a wider range of concepts and practices. This study opens a discussion into the scope and suitability of the method used here to generate heuristic dimensions by managing information from social behaviors.
