The essay is here https://projectinfolit.org/pubs/provocation-series/essays/the-ischool-equation.html and there are some suggested discussion questions here https://projectinfolit.org/pubs/provocation-series/essays/discussion-questions/ischool-equation-dq.html
Spoiler alert - the author concludes that library students are not being adequately prepared for teaching, and makes some good points.
