I am pretty late in generating this post, but I thought some educators who focus on writing would be interested. Marginal Syllabus is multi-month activity for secondary and higher ed writing instructors to explore collaborative reading and annotation. The group will explore one challenging article a month and annotate to discuss this article with each other, with the author, and with other scholars. The collaborative activity makes use of Hypothes.is – a layering (highlighting and annotation tool for online content I discuss elsewhere) – and exposes educators to strategies for collaborative reading and annotation they may find useful in their own classrooms.
Whether you actively participate or not, this site is interesting to explore as it offers some interesting ideas about using annotation as an active component of a group reading project.
