I think you're right.
Slightly related, I can't find the research, but I read research that teachers apparently explain concepts more understandable when they use accompanying hand gestures.
Oh and also, when explaining statistics, don't use decimal numbers like 0.001%, just multiply it by a big number like 10000 and you can use whole numbers again. So of the one million people in our country, 100 experience XYZ. There also have been multiple papers on that one (can't find them ).
Those are two my pedagogical tips of the day :P
 Okay, I'm too lazy, it'd take me 15 to 30 min. to find both of them, since they come from my psychology time between 2012 and 2015.
Maybe it was this one?
