Students are assigned parts (chapters/subchapters/paragraphs) of content and annotate these with a summary.
Detailed task/case (for lecturer and students)
“Write a summary of the (sub-)chapter xy and post it as a comment where it belongs! Use the annotation function to write the parts of the summary, working on it together. When the content of the summary can be put together, one person should copy/paste everything into one annotation/comment and everybody deletes all the other annotations that are not of importance anymore.”
As a follow up, ask students to review / comment on other students’ work.
Profit
students would have summaries available.
Caveat!
