Dialogic Online Videos in STEM Learning 

Despite the tremendous growth in online mathematics and science videos, the dominant model is still a talking head or hand presenting a lecture or solving tasks. In contrast, alternatives have begun to emerge that feature dialogue, often between a tutor and an undergraduate, in biology, physics, and computer literacy. We were inspired by such work to create a model for dialogically-intensive, conceptually-oriented math videos for secondary school students (available at https://mathtalk.sdsu.edu/wordpress/). Each video features the unscripted dialogue of a pair of secondary school students as they convey sources of confusion and resolve their own dilemmas by arguing for and against particular ways of reasoning. Other students who learn by viewing and engaging with the videos are called vicarious learners (because they are participating in the original dialogue indirectly). This talk highlights research studies on vicarious learning – from our project and from other STEM disciplines. I also discuss theory regarding the foundations, benefits, and constraints of vicarious learning.

Dr. Lobato’s research has involved developing the actor-oriented transfer perspective, which led to an interest in “noticing” from both psychological and socio-cultural perspectives. More recently, Dr. Lobato has been motivated by the need for alternative models of videos to... Read More →
