Maria at Teaching College Math just posted some examples of using W|A that are interesting and could be of concern. W|A gives you all sorts of information related to the search you enter. This can be great, but could also cause some issues with academic dishonesty, depending on how that information is used.

W|A could be a great place for students to get graphs that they could then post on a Discussion Board, or even to print out as part of an assignment ,not one that is focused on the student creating the graph, but one that is doing a more in-depth analysis of the graph. It is definitely a site that we, as instructors, need to be aware of. I will be interested to see how other instructors decide to use W|A in the classroom. If we are directing the use of the site, students will (hopefully) be using the resource honestly as a supplement in the learning process.

Walpha Wiki
This wiki will be tracking how Walpha might be used by students and as a tool in outside the classroom. As stated in the wiki:

A few of us interested in exploring the implications of Walpha on secondary and undergraduate mathematics education thought it might be useful to have a wiki where math educators could contribute documentation regarding Walpha's use in such teaching contexts. In particular, we're interested in documenting how Walpha can handle or help with handling common problems asked of students in these courses, as well as how Walpha might be used as an instructional tool when teaching students about related content.

It will be interesting to watch this wiki as it changes.

• Wolfram Alpha with Google Firefox Add-in
  Display Wolfram Alpha results in Google searches. No need to switch search engines when you can use both at once!
• Parade of Games in Powerpoint
  I've seen this site before, but not when I was working from a computer with LCD projector every class meeting. Going to have to explore here a little more now to see what is usable in my classes.
