I am an educator of various tech, design and research aspects since 2000.
A main aspect of my teaching philosophy is to transform students to active learners. Active learners are students in control of their learning process. Instead of being spoon-fed by the lecturer, active learners are able to set their own goals and organize their time and learning activities.
I hope with this channel to support active learning for all of my students!
