How would you teach the same class to a bunch of middle school students and a higher ed class?

Our US history survey is split into 1 class for new students and 1 for more experienced students. The material is exactly the same. It is supposed to be designed to adapt to the different skill levels/needs of those students. I thought I’d ask all of you, how would you approach the same course for middle schoolers vs adults? <br><br>I make the assumption that middle schoolers need more social skills training and need the subject broken down into bite sized chunks whereas I think the college-aged kids need to dig a bit deeper. <br><br>For example, I teach maps. A map is like a puzzle piece - you look at it and get a visual of where something fits. You match the edges so that you can see the whole picture. For middle schoolers, I use a puzzle piece model, but for college kids, I’m showing them how certain maps have influenced historical events (for example, the Peters map and its impact on Cold War propaganda). <br><br>I’m curious as to how you all approach the same subject for kids who are at two very different places in terms of cognitive, social, and emotional development.
