In view of the challenges facing universities in our days and in accordance with the guidelines of the EHEA, the present article presents the results of a project which aims to unite the use of blogs and a competency approach. Specifically, the project is structured around two basic, complementary aims: 1. The design and implementation of a teaching innovation project which through the use of blogs promotes the development of certain professional competencies and 2. To assess the experiences and comments of students regarding the use of blogs in a university context, in order to appraise how students assess the use of this new learning tool. To achieve the latter aim, we used a methodology that combines a questionnaire with content analysis, using a sample of 82 subjects. The article shows that university students consider the blog as a tool that enables the acquisition of professional competencies, boosts the teaching-learning process, and foments the development of reflection. Based on these results, several proposals are made concerning the use of blogs, including activities related to reflection, provision of training-focused feedback, and the use of labels as an exercise of metareflection, amongst others.
