My WebQuest has changed minimally since I last blogged. The topic now covers relating real-world quadratics to their parabolic graphs -- helping students understand the utility of quadratic functions in society. When students can understand and appreciate how math is used for important functions in society (i.e. satellites, bridges, mirrors) they gain a deeper satisfaction with the knowledge that their work in class is purposeful.
In designing the WebQuest, I haven't had many frustrations, except for the compatibility issues between QuestGarden and Microsoft Word -- a few issues I still need to work out. I think the grade-level ranking is pretty pointless, since it's quantitatively objective and shouldn't necessarily be...making it fairly inaccurate. It doesn't really bother me though, I have just ignored it. Other than that, it's really amazing how teachers can collaborate by using one another's WebQuests...all available in detail online.
