Uses in the Classroom
Mind Maps, as an artifact created by an instructor, can assist students in seeing connections to other content/ideas, as well as being a demonstrative breakdown. Mind Maps, as artifacts created by students, can help students demonstrate how they see one item/person in connection to other things. Therefore, Mind Maps could be successfully utilized for classroom use as both resources and activities.
Issues to Consider
Unless the institution has purchased a mind mapping software, the trial opportunities may be too short to be useful. For example, Gliffy's trial period is just 30 days, I believe. In addition to this issue, students would need time and access to online materials, and some education involving copyright licensing in order to avoid violation of authorial rights for photos/videos.
