This paper elaborates on the didactic implementation of musical theater with undergraduate education students. Students had to select, prepare, justify, design, elaborate, rehearse, stage, and record an educational tale that targets ecological and environmental values in its main plot or storyline. Due to the COVID-19 pandemic, the implementation of this didactic proposal went online, and the interactions between students took place through video calls. This study surveyed a sample of 86 participants (n = 86) from a population of 116 students (N = 116) from the Faculty of Education of Albacete (UCLM) to investigate the advantages and disadvantages of carrying out this activity in an online format. The main challenges exposed the complexity of coordinating a team in a completely online format, problems related to physical isolation, and the limited access to a high-quality internet connection. The reported benefits included the development of digital competences, the interactions through social media, and creative thinking. Most students viewed this activity as didactically innovative and 98.84% agreed that musical tales and musical theater can be useful for promoting environmental awareness.
