Second, it lets you see the course as a whole to get broader connections between ideas spaced apart in the lectures.
Now I sort of understand what the speaker means about making connections and he seems to have a good strategy for it. By putting class material closer together, that would otherwise be more spread out, you can literally connect concepts, information, and ideas. Maybe you could connect them with a pencil line. But this makes me think about how I tend to think of class material as all separated and think in a way that is test to test. If that makes any sense. I basically try to remember information that I only need for a given moment.
