Teaching how to design a mobile app or a website is pretty much like teaching Digital Marketing. We tend to think that students who are part of the social media generation would know how to keep things simple. The reality is actually far from it. For people who have a short online attention span, they struggle to come up with content or design that could be understood almost immediately.
This is why as a UX UI lecturer I usually make sure that during the first sessions of this course they learn how to K.I.S.S (Keep it simple stupid). Once they understand the basic principles of UX UI, and how to win an audience, they can start designing websites and mobile apps in a professional way. Since I am also a web design lecturer, I help students launch their websites and start their own online ventures!
