Sci-Math World is designed for teachers and librarians who wish to expand their knowledge of science & math education Web resources.  This Web site contains many resources that today's searchers need, whether they are K-12 or higher education students, educators, or parents.  Together, this hands-on class & Web site will provide the tools to locate valuable, reliable information on the ever-changing, rapidly growing Web.

Selection of Search Tools: The Basic Three

Begin with Directories and Portals when:

• you have a broad topic
• you want access to selected, evaluated, and annotated collections
• you prefer quality over quantity
• you want to locate Web sites rather than individual pages within these sites

Begin with the Invisible or Deep Web [searchable sites and databases] when:

• you are looking for information that is likely to be stored in a database
• you are looking for information that is dynamically changing in content

Begin with Search Engines when:

• you have a narrow topic
• you are looking for a specific site
• you want to gather a large number of results
• you want to take advantage of the newer retrieval technologies

Directories and Portals

• Librarians' Internet Index (http://lii.org/) - Websites You Can Trust: LII offers a searchable and browsable collection of over 20,000 quality websites, "maintained by librarians and organized into 14 main topics and nearly 300 related topics," in addition to an excellent weekly newsletter [they have over 40,000 subscribers in many countries], available by email or RSS, of high-quality Websites related to current events, holidays, and popular and important issues. Features include icons following the titles allowing you to view more details, make comments about, or e-mail the site. Of course, LII can also lead you to free Web databases by typing in a broad topic and adding the words: "and databases" (i.e., biology and databases. You can also quickly find sites on Science & Math by clicking onto the "Science" link and choosing from a sub-topic (i.e., Mathematics) on the page or viewing the "General Resources" links.
