We firstly introduce the theoretical background on outdoor mathematics, focusing on math trails with the digital tool MathCityMap and professional development to be accomplished using MOOCs. By taking into account the MOOC "Task Design for Math Trails", with 93 finalists, we analyze the learning progress of 19 selected case studies from different nations and learning levels by taking into account their answers in a pre-and post-questionnaire and their posts on a specific communication message board, with a special focus on the MOOC's topics' task design for outdoor mathematics and the digital tool MathCityMap. The analysis is performed using different quantitative and qualitative approaches. The results show that the teachers studied have benefited from professional development, which is evident in the expansion/evolution of their knowledge from a content, pedagogical, and technological perspective. Finally, we formulate consequences for professional development in STEM education, and conclude the paper with limitations to be drawn and a perspective for further research.}, organization = {The MaSCE3 MOOC was made possible with the support of the Erasmus+ Programme of the European Union (2019-1-DE03-KA201-060118). A special thanks go to all the MOOC instructors who contributed to the preparation of the resources in the various modules and who collaborated, together with the technicians of the University of Catania, in monitoring the delivery of the MOOC. Therefore, in addition to the authors of this contribution, we would like to thank Virginia Alberti, Roberta Ferro, Sara Labasin, Gerardo Maiorano, Gregor Milicic, Andrus Rinde, and Angelo Sarra Fiore.
