RT book part T1 Promoting global awareness of the SDGs in the classroom through the SDGCalendar platform A1 Jiménez García, Ezequiel A1 Castro Cabrera, María Carmen A1 Balderas Díaz, Sara A1 Guerrero Contreras, Gabriel José A2 Ingeniería Informática K1 education K1 App K1 Sustainable Development Goals (SDGs) K1 interface evaluation K1 interface validation AB This paper presents the design of SDGCalendar, an ecosystem of both a mobile and web application that aims to introduce the teaching of Sustainable Development Goals (SDGs) in schools. This system employs current technologies to deliver a robust and intuitive user experience to both students and teachers, by providing access to SDGs, international days related to SDGs (hence the name SDGCalendar), and activities and questionnaires.To evaluate the viability of the project, two separate usability tests were conducted with distinct user groups to test the interface of the mobile implementation, SDGCalendar APP. Preliminary findings reveal that SDGCalendar APP is not only user-friendly but also highly efficient in performing its intended functions, while highlighting areas for improvement, providing valuable insights that will guide future development, such as readability. With SDGCalendar, we believe it is possible to raise awareness of the SDGs inside schools while making it enjoyable to both teachers and students.
