Computer Based Instructional Objects

Much like writing code for a computer program, when creating a computer based instructional object, the author must anticipate many different scenarios. A plan has to be in place with a goal in mind and all of the "what ifs" addressed. I can imagine that several iterations are needed to eventually get to the final product. Also, the author needs to think about which pedogogical strategies will be used and whether or not any students have disabilities.

Here are three WebQuests I found to be very good.
1. Constructing Your Own Geometry and Algebra Based Objects by Daniel Keeler - I like this one because it addresses a lot of the basics of Geometry using a website called GeoGebra which looks like a lesser (and free-er!) version of The Geometer's Sketchpad. The author used a lot of scaffolding with a few links to basic definitions and examples.

2. We Hold These Truths to Be (Evident) by Charell Wingfield - This is a long term Webquest that seems to do a good job with the difficult task of proofs in geometry. Teamwork is required and the main strategy is inductive.

3. What Price Will You Pay to Go the Distance? by Tracey Betschart and Elizabeth Kuniak - This incorporates the use of triangles and bearings in determining the most cost effective travel plans. I really like the relevance of the topic. The strategies used are scaffolding and deductive.
