I use Twitter to create a "Twyllabus" for my Introduction to International Relations course. In 2018, I used Twitter exclusively to post weekly readings. In 2019, I opted to place the "Core Readings" on a physcial syllabus, and then post additional (but still required) readings on Twitter.
For each year, the class had a "hashtag", either #ChicagoIntroIR2018 or #ChicagoIntroIR2019. Clicking on a link below will take you to the Twitter page that lists, in reverse chronological order, all of the tweets using the respective hashtag.
For example, if you wish to see all of the tweets I posted for my 2018 Intro to IR course, simply click on the #ChicagoIntroIR2018 link below:
