At times I offer lectures in various settings from introduction to specific tools and frameworks to general problems and concepts of IT (such as DNS or Email). Topics depend on the setting and group. Another set of possible subjects are Electrical engineering and basic mathematics related ones.
I like lectures which are interactive and involve the listeners most. A slideshow presentation with someone reading out loud the slides' text doesn't work in any way. Such a lecture doesn't help a listener to gain knowledge. That is why I prefer to use a selection of the options I have (e.g. using a blackboard in addition). Please let me know what tools I can use and what possibilities there are for me to make a perfect lecture for the listeners.
