Mathematics training in engineering degrees: an intervention from teaching staff to students
López-Díaz, María Teresa; Peña Carrera, Marta (Multidisciplinary Digital Publishing Institute (MDPI), 2021-06-23)
Article
Accés obertThere has always been a great concern about the teaching of mathematics in engineering degrees. This concern has increased because students have less interest in these studies, which is mainly due to the low motivation of ... -
