Multiplatform Development of Audiovisual Open Educational Resources for a Blended Flipped Classroom Experience

This paper presents a walkthrough about developing educational audiovisual contents to produce OER (Open Educational Resources) and the use of these resources in a blended flipped classroom. All along the paper we detail the process of developing this educational material and the later use of it. Several operating systems (such as Windows, Android, and iOS) and (free and commercial) applications were involved in the developing of the resources. The combined use of these tools has allowed us to produce a long list of educational videos, which use several formats to show the contents to the students, avoiding the monotony that may show up during their watching. Specifically, the content of the videos is related to educational material used in a first course of telecommunication engineering, in the matter Computer's Architecture. These videos are used to carry out a blended flipped classroom educational experience over two classes in these course (each with approximately 30 students). We think that the work presented in this paper can be used as a guide by people who want to make videos for their own flipped classrooms (even with the support of our OER videos).
