I use moodle for class outlines and material, and was dismayed to discover that when I opened them from within the class moodle page I could not scroll down beyond the opening "screen shot" that appears when the outline opens as a window within the moodle page window. But I learned how to get around this problem. If you haven't learned this secret yet, here are some instructions.
(1) Go to the relevant moodle page and "Turn editing on."
(2) Click the "Update" feature for the item you want to open in a window that can scroll.
(3) Go to the "Options" box and choose "New Window" from the pull-down menu next to the "Display" feature.
(4) Click "Save and return to the course" and you're done.
Next time a few words on the program that I use on the iPad in class to display primary texts. It was the reason I wanted to be a part of the program, and it's working wonderfully.
