Instructor inking during class

The left images is the uninked slide. Everything on it was prepared before class. Subsequent ink appears as it is written on the screen of the TabletPC during class.

In this example, ink was used to link multiple representations. In the middle slide, green ink has been used to link the pictorial representation of the ball hitting the wall with the graphical representation of the force as a function of time. Later, parts of the mathematical representation are connected to the pictorial representation. Green is used for the superball and yellow for the clay ball.

The images below show four slides used to work through a very detailed example problem. In each case, the fully inked slide is shown. The ink doesn't appear all at once, but as it is written.

This sequence shows three slides introducing snapshot and history graphs as a way to represent wave pulses, followed by four student submissions (notice that 3/4 got it right!), followed by one last slide showing the correct solution and discussion. In each case, the fully inked slide is shown.
