In regards to Pitfall #5: “Ignore the ways students learn from each other”. In my experience including assignments that require students to work in groups and share ideas and resources, and present on their topics is a great way to encourage a collaborative learning environment.
It seems that the collaborative capability inherent in wikis leads to multiple instructional applications that would encourage such learning. Wikis can be used to disseminate information, provide instruction, and promote collaboration among students. I have never personally used Wikis in my online courses but look forward to learning more about it and will definitely use it as a classroom assignment for my new hybrid course.
