I have done webquests in the past, but I have not incorporated the elements of an effective webquest as stated above. In the past, I have given the students a questionnaire or worksheet with steps to follow on a particular website and they would read through lessons and work on some self-assessments. For example, we were learning about daily routines in my Spanish II College Prep 1 class last week and I was having a really difficult time with reflexive verbs; behavioral issues aside. Some students were understanding it well but most were not. I designed a webquest activity, before reading the assigned reading for this week, in which I gave my students steps to follow a lesson on StudySpanish.com. In there, they went through the lesson, did some self-assessments, and also practiced pronunciation of the terms in a listening and speaking portion on the website. One of my lower students mentioned to me on the side, "I wish you had done this sooner", namely because she can work at her own pace and also have the lesson written explicitly instead of a power point lecture or group work. I also noticed another student, one of the behavior problems, define and explain to her neighbor what a reflexive verb is, all without me saying a word during the entire block. I can only imagine how much more effective that web based activity could have been if I had only incorporated the six parts and real world application.
I have not used the website WebQuest.org either. I like the templates the aforementioned website showcases, but unfortunately it is out of date; the search engine is not working for me at the time of this writing. The idea behind the website is a good one, I think I will continue to explore webquests with more seriousness and incorporate them regularly into my lessons in the future. Perhaps this could be a fun and effective way of working through the boring grammar drills or enhance the culture lessons even further.
