I’m not about to become an authority on the subject of constructivism, but one of the challenges with early online learning where instructors who knew their subjects very well but didn’t understand how less-productive it could be to just toss students into an online learning environment and expect that their instincts would take over and they would just ‘figure it out’. Most distance-learning students (including myself) have a certain amount of online survival mechanism built in that very closely mimics survival in the real world.
I am Martin Lehner and I work in the CTL doing programming, system administration, and technical black magic. A great deal of my time is spent installing various applications on unix or linux servers. To get an idea of how complicated that is.. allow me to confuse the heck out of you… (more…)

However, I gathered from her short description that one of Tufte’s main complaints is that PowerPoint imposes a linear structure on the delivery of information that obscures the connections between the ideas presented.

For a long time one would have to break out the old magic wand or lasso tool and carefully select around the portion of the image they wanted to remove the background. Then copy the selection and place it on a new layer or canvas. That is now a thing of the past! (more…)
