 Good morning, and greetings from Canada. It's a real pleasure to be able to be invited and an honor to be invited to do this keynote at Eden Research Network conference. I have a very soft spot in my heart for Eden Research Conferences because it was the very first one international conference that I got invited to do a keynote at in Oldenburg many years ago, and I guess I told enough jokes that I kept getting invited back. So I would have much sooner been able to enjoy some Portuguese culture and wine with you in Lisbon, but I'm settling for a chance to talk to you, and I hope that when this presentation goes that you'll have some comments and some questions for me and for all of us. So let me start by sharing my screen, and I will go to here, and I will share that, and I will start the slide show. So the title of my talk is going to be a quality through three generations and aggregations of online learning. And one thing that I've been sort of asking a lot of people that I meet, whether they be students or teachers who have been thrust into teaching online since COVID times, is, you know, how is your experience of online learning? And what surprises me is the variety you hear. You get some people say, oh, it's terrible. I can't wait to get back to the classroom. And others say, oh, this is the greatest thing. I can have freedom to pay attention to what I want to pay attention to. I can multitask. I can network with my friends. I can take care of my kids while I'm still enrolled in school, so that we get a huge variation. And yet we call this all online learning. So what I wanted to do in this presentation is talk about the different kinds of online learning and paying a special attention to the different pedagogies that drive it. And Samantha McMahan from Sydney wrote a blog where she says, I kind of got better at teaching online when I stopped saying what I can't do and started asking better questions, like what pedagogical principles drive what I normally do, and then how can I appropriate and use those in an online environment. And so what I'm going to do in the talk is to go through an older article that I wrote way back in 2011 with John Braun. And I sort of looked at online learning through three different models or pedagogical designs that underplay it. And what I'm going to do is try to talk about the newer technologies as they've evolved since 2011, and the research techniques that we can use to study each of these three. And these three are behavioral cognitive model often used in training. The social constructivist model, which you probably are very familiar from classroom instruction, which is the smaller classroom instruction, and then the emergent connectivist pedagogic for online learning. And I hope that these advice I go through each of these, you'll see which one resonates most specifically with yourself, and your teaching institution, and your teaching context and maybe most importantly with your students. So with that, I will pause and end by just saying that I'm looking forward to talking to you at Eden Research Conference number 11. Thanks very much.
