The knowledge of technology directly impacts the subject under study and, ultimately, the student learning. The students’ learning is maximized when technology is tailored to the subject and to the teachers. In this work, we re-designed an engineering course in electromagnetic compatibility to include pedagogical concepts supported by technological tools. We adapted the main ideas from the Technological Pedagogical Content Knowledge framework and designed the web platform based on pedagogical knowledge and technological knowledge. The course in electromagnetic compatibility consists of laboratory activities that cannot be virtualized or digitalized. Moreover, we wanted to keep some of the on-campus classes to increase engagement in the course. Therefore, the final course resulted in a mixed or hybrid education experience. The re-designed course had more positive assessments than previous courses taught with a traditional format.
