Recently, Nic Bongers told me about the segmenting principle, from the cognitive theory of multimedia learning. From a segmenting principle page:

Segmenting is a very simple principle ... breaking down the large segments [of a lesson] into smaller segments.

In [Mayer, Dow, & Mayer, 2003], the learners viewed a lesson on electric motor workings in an animation that was continuous. Other learners viewed the same set up but this time in a segmented version. With the material being identical to one another, the only difference being the segmented lesson had a continue button, the students performed better after having learned from the segmented lesson.

Skilling has something that would help. When you're writing a lesson, you can type:


That will make a button for students, like this:

Pause button

The rest of the lesson is hidden, until students click the button. Then:

Lesson continues


A question about that. I can see how segmenting would help, the first time you read a lesson. But if you're skimming a lesson later, looking for something, having a bunch of buttons would be annoying.

Yes, I agree. So, every button has a drop-down on it, like this:

Show all

"Show all" removes all the pause buttons from the page, and shows the entire lesson.

The pause tag was added before Nic explained what segmenting is. Now I have a name for what the pause button does. Cool! Thanks, Nic!
