The aim of this article is to present an evaluation of digital teaching skills in a project funded by the National Distance Education System (SINED) in Mexico conducted on a Massive Open Online Course (MOOC) which was designed to develop competences in teachers in the distance learning or classroom setting for the integration of open educational resources (OER). The course was conducted by the Regional Open Latin American Community for Social and Educational Research (Clarise), and posed the question: how are distance learning didactic competences using OER developed? The aim was to identify and evaluate how OER were used and the form they took throughout the stages of the open education movement. The study deployed a mixed methodology with instruments such as emailed questionnaires for the MOOC participants, viewing screens in the discussion forums and anecdotal evidence. The results show that MOOC participants were able to develop digital teaching skills, identify how to use OER and how the training process occurs in the open education movement. Constraints to the development of these skills were also seen in the acculturation in the open education movement, as well as limitations on the design of distance learning models that promote these skills and the recognition of informal learning.
