I like Google for their approach, how they introduce new technology concepts for freshmen. A good example is the teachablemachine, an interactive machine learning experiment. As they state
“From helping you find your favorite dog photos , to helping farmers in Japan sort cucumbers , machine learning is changing the way people use code to solve problems. But how does machine learning actually work? We wanted to make it easier for people who are curious about this technology to learn more about it. So we created Teachable Machine , a simple experiment that lets you teach a machine using your camera—live in the browser, no coding required.
