When f2f classes were canceled and all instruction moved online in March in the US, I turned to WeBWorK. The platform, along with its extensive Open Problems Library, provided enough utility to not only serve as a summative assessment tool, but also as a means to deliver asynchronous content and formative assessments to my students. In this lightning talk, I’ll discuss how I leveraged the OPL and small changes to the essay prompt, solution subroutine, and iframe embeddings to deliver asynchronous lectures with conceptual understanding exit tickets to my multivariable calculus class.
