I first came across Nidhi on Twitter, where she shares these amazingly digestible “Microlessons” about cognitive science topics such as interleaving, biologically primary vs. biologically secondary knowledge, and The Matthew Effect. Not only will Nidhi take us through the process of how she designs these punchy little Microlessons over the course of this episode, but afterwards you can try them out for yourself by clicking the links below – no log in required.

  2. Is Multitasking Real? –

I also wanted to invite listeners to attend a free webinar that I will be hosting at the end of March 2023 through the Australia-based organization, Think Forward Educators. This one is all about Rosenshine’s Principles and explicit instruction, and the presenters will be Bradley Busch – who you already know from a previous episode of this podcast – and Christie Barrett. Consider signing up no matter what timezone you’re in so you can gain access to the recording.
