I have had many experiences creating Wiki pages and Blog pages. This technology can assist online instructors when standard on-campus software does not meet the needs of the course instruction.
Due to the Wiki pages being password protected, I have pasted a screen shot file of my UW-L graduate alumni site that I have created. This site helps my graduates keep in contact with each other and myself, and keeps an ongoing collaboration between classmates as well as valuable resources for them.
I have also created a Wiki site as a collaborative peer group project for my students in their brachytherapy course. They worked together to research the properties of radioactive isotopes which enabled them to prepare a study guide for the national board exam. Their work is published at this site.
