I give credit to K. Howatt in 2018 for asking this. I, too, would like students to read material and passages on a Canvas page, then answer a question at the bottom for comprehension-checks with an embedded Canvas quiz. Including the link to the quiz on the page seems to take the student out of the page and into the quiz; the flow is disturbed, and it seems like the student has to navigate her way back to where she had left off.
I'm not looking for a stimulus question--I'm thinking along the style of SoftChalk, if that helps.
