Finding information is easy with the hypertext links in the navigational columns. The site's search engine contains simple Boolean options and pulldown menus to narrow or broaden searches. Navigational aids include the site's consistent layout of hypertext links in the extreme left and right hand columns. No other navigational aids are really necessary with this consistent layout design. Information flow , in general, is logical from one page to another.
Several pages contain links to outside resources.
When needed, these lists of links are accompanied by quick descriptions. The information flow within the lessons flows logically from one page to another. Several pages are linked directly from the hypertext navigation columns, which produces a direct link sequence, rather than an informational flow. Effects used include animation sequences and Java scripts. A few samples found in the lessons include probability spinners and practice questions with immediate feedback.
