Hi, everyone. In this week, you will get a "big picture" of IT industry through reading and learning online videos. Could you talk about the changes that IT has brought from a specific aspect, and give some examples? From my own perspective, I think that IT has changed my way of working a lot for the past 10 years. Getting involved in online teaching has given me a lot of challenges but also inspiring experiences. I have to spend much more time on getting used to multimedia tools, researching for new teaching method and prepaing for teaching materials. Meanwhile, designing interesting slides for learners and getting positive feedbacks from them are also exciting moments. What about you? How has IT changed your life? :)
