How do you annotate?

Annotating things - be that texts, images, videos, etc. - can be a rich and useful learning activity that promotes critical thing and active engagement with whatever is being annotated. In other words: it is a useful learning strategy. Here is a selection of useful tech-tools:

• Video Annotation Tools: VidBolt, VideoANT, or SocialBook. Adeline Koh has a nice article on using VidBolt in the classroom over on ProfHacker.
• Film Annotation with SocialBook - read about it here on ProfHacker.
• Text / Website / Collaborative Annotation Tools: Hypothes.is, nb, Annotation Studio, eComma, Axiom, Diigo, Classroom Salon, or Lacuna Stories.

Lot's of choices here...try Annotation Studio (MIT) or VideoANT (University of Minnesota) to get started. Or consider the opinions discussed in the article and comments by Lee Skallerup Bessette over on ProfHacker and read about Hypothes.is in Nature (3 December 2015).

Update (14 January 2016): Maha Bali has a nice comparison of Hypothes.is vs. Diigo over on ProfHacker.
