In order to continue reaching students after lecture, I created a series of video tutorials aimed at unpacking many problem solving methodologies we emphasizes in class. The University of Notre Dame built a studio for video recording dubbed "lightboard", which allows instructors to record content using a glass board as if it were a whiteboard.

Pedagogically, these Lightboard videos can be thought of as "just in time" teaching moments. Students are able to problem solve while simultaneously observing the solution method for a similar problem. By making this content available, students are able to interact with the problem solving process hopefully mitigating the time spent rediscovering what was learned in class.

The barriers to enter here are very low. You don't need a light board studio to get started with this process. Using desktop capture software, like activepresenter, to explain a cognitive skill while also addressing the pain points of problem solving is as effective.

Unlike traditional desktop lecture capture, the post-lecture videos can be aimed at connecting the dots quantitatively so that students can focus on making qualitative connections.

Focusing on creating a solution that comes in at under 10 minutes can help reduce attrition and boost retention.

To begin your own classroom example

• Identify a topic which students generally find confusing, difficult, or mathematically challenging
  • This can be either historically or from what you saw in class that day
• Review how, as an instructor, you want to position the main takeaways either quantitatively or qualitatively
  • Deciding on the content of the video can help guide your process. Is it a step by step guide to solving a problem or is general theory that can be traced to real life applications
• Focus your content on unpacking the problems you see students encounter
  • Its easy to stray in these videos. Keep them tight, short, and to the point
