Last spring I used a wiki in a course for the first time. It had its ups and downs, but for the most part it went well and it was a useful tool. However, as these things go, it of course had some pitfalls (caused by me, not the wiki itself) — the most surprising to me was the way that student collaborative writing went. The ease of collaborative writing was the aspect of using a wiki I was most sold on, and it did not work out at all the way I’d expected.
