As software becomes increasingly important, so does the education of people who develop software. To provide a good and motivating education to learners, it is necessary to be aware of their preferences. To give insight into the preference of learners, we conducted a study with university students and professionals aimed at learning more about their preferences. Results from our survey- and focus group-based research show large similarities between both groups of learners, such as the preference for e-learning materials, as this provides them flexibility for scheduling their learning sessions. However, differences exist when it comes to the preferred scheduling of online and offline sessions. Our findings can help educators not only in designing courses for university students or professionals, but also in designing courses that can be used by both groups of learners.
