How do you plan timing for a lesson, balance active learning with lecture, and get students engaged and excited to be in class? Listen to this episode of the STEM Course Design Series to get answers…
The first thing I want to say about in-class teaching is make it fit your style.
It's probably the most important thing I'll say today is that you can go and see other people teach.
When you're in a workshop with me, you'll see how I do things and you'll get my figure out my style.
If you have colleagues telling you, you have to do X, Y and Z with active learning or you have to lecture this way or use this slide design.
No, that's not true, right? It's up to you because the in-class teaching part of teaching really is the most personal of the realm of course design and teaching, in my opinion, right? It's where you, your actual voice, your mannerisms, your eyeballs, everything comes into play.
So when I do active learning a lot, and we'll talk a lot about that today too, when I walk around the room and I get my steps in, I like to say.
I'll answer questions if they raise their hands, of course, but I don't really pop in or pry into what they're saying.
But I have colleagues who they'll walk around and they'll pull up an empty chair and sit down and make direct eye contact and say, what do you think? What are you talking about? It's just not my style.
