Aspectos metodológicos para la elaboración de videos docentes para su uso como objetos de aprendizaje modulares y reutilizables

The objective of this work is to reflect on the main methodological aspects to take into account in the development of video teaching for use as modular and reusable learning objects. This reflection is one of the results of the work carried out by the authors in a teaching innovation project funded by the University of Zaragoza during the academic years 2015-16, 2016-17 and 2017-18. In this project, 25 educational videos under licenses have been created to improve the learning outcomes of five subjects in the field of thermodynamics and thermal engineering, currently taught at three different qualifications. Preparing educational videos requires different strategies compared with an in real time session and aspects such as the approach of the contents, the adaptation to the environment and technical quality influence the effectiveness as a learning tool by what must be taken into account in its development phase.
