While researching for Web 2.0 Tools that can be used in the classroom for the different AVK Learners (Audio, Visual, Kinesthetic), I came across a good site "100 Helpful Web Tools for Every Kind of Learner".
This article lists 100 tools divided up into the appropriateness of each tool to AVK learners.
This site explores different tools for Visual Learners - 34 in fact - divided into 3 categories: Mind Mapping; Charting & Diagrams; and, Videos and Photos.
For Audio Learners, there are 31 tools divided into the following categories: Podcasts; Presentation Tools; Audio Tools; Text Readers; and, Audio Books.
For Kinesthetic Learners, there are 34 tools listed in the categories: Note Taking Tools; Bookmarking; Interaction; and, Collaboration.
This collection of tools offers teachers a range of tools that can be incorporated into the classroom even if you are not using WebQuests. They are there to be investigated and will enhance any lesson.
I can see their great application to WebQuests. These tools will enable the teacher to create WebQuests that will cater for all their students covering all the AVKs.
