The main purpose and focus of the MATEL workshop series on Motivational and Affective Aspects in Technology Enhanced Learning has been to stimulate interdisci-plinary exchange and joint research activities on understanding and addressing motiva-tional factors and emotions in learning solutions. There is hardly any opposition to the importance of these factors for the success of these solutions. However, there was al-ways a major lack in systematic support and scientific rigor in the interdisciplinary field so that it was characterized through anecdotal evidence and hard-to-generalize results. In 2013 and 2014, From Art to Engineering has become the major motto of the MATEL workshop series. In this report, we bundle the 2013 and 2014 contributions that show steps on this journey.
