The website located at http://crew.sdsu.edu/aviNiolent.html/Introduction.html is an educational resource for high-school students grades 9-12. The website conforms to the theme-related pedagogy established by the California Science Framework for Public Schools. The "framework" stresses that science should be taught through the integration of concepts rather than through rote memorization of seemingly unrelated facts. Our website is to be used as a educational guide to the nature of volcanic eruptions. Concepts within the website are connected through the general theme of"explosivity". The chemical controls on the explosive potential of eruptions are briefly described in the introductory home page. The website is then subdivided into two parallel topics based on the explosive potential of volcanism: "Violent Eruptions" and ''Non-Violent Eruptions". We describe each of these eruption types in a parallel fashion with links to the same subcategories: (1) eruptive styles, (2) magma types, (3) volcano morphology, and (4) the effects on humans. Within this context, the contrasting features and processes associated with each eruption type can be easily recognized. The website concludes with a link for the reader to test his/her knowledge on violent and non-violent volcanism. The website uses integrated concepts to provide the reader with an educational environment conducive to learning at the high school level. One of our goals was to make the website interactive and fun, as well as educational. Testing of the website demonstrates that our overall goals were met. The individuals tested found the site to be interesting, fun, and educational. They were also able to follow the general theme of the website and recall the basic ideas and concepts.
