  8. Educational uses of the web:“From surfing to serving” • Initially people see the Internet as a vast source of information • The web as a distributed hypermedia

  9. Hypertext & Hypermedia • Our class web page as a hypertext • What is hypertext? • Text that can be read in multiple ways • Print hypertexts? • Hypermedia: hypertext+graphics+sound+video+animation+etc.= hypertextual multimedia

  13. Education and the web • The Global Schoolnet web site • Harnessing the Power of the Web

  14. Search Engines • Databases of web resources • Two kinds • Directories (human classified) - Ex: Yahoo • Web crawler-based (not human classified) - Ex: Excite • Which to use? • Use whichever ones you find useful • When you don’t find one useful, switch to another

  15. Understanding URLs • A unique address for each web resource • Structure: what + which computer + which file • Example:http://www.ed.uiuc.edu/courses/edpsy387/fa99/index.html • What kind of resource: http:// -> Web file • Which computer: www.ed.uiuc.edu • Which file: courses/edpsy387/fa99/index.html

  16. Understanding Computer Names • Domain names: used both for computer names in URLs and in email addresses (whatever is the to the right of the @ sign) • Like a postal address, but with “.” instead of new line as separator • Most general to most specific, right to left

  17. Example:www.ed.uiuc.edu • From the right: edu -> US higher education institution • com --> US commercial institution • gov --> US federal government • org --> US non-profit • us --> US • mx -> Mexico • au -> Australia • Country code list: http://externic.net/iso.htm

  21. Sending/saving URLs • Have to get the URL exactly right (sometimes case mAtTeRs; no spaces ever) • Copy & paste is best • Emailing from your web browser • Advantages: can do anywhere • Disadvantages: need to set & then unset email preferences • Emailing yourself

  22. Using URLs to evaluate web sites • Largest level domain: .edu vs. .com vs. … • Subdomain elements: .ed.uiuc vs. .cs.uiuc • Directory elements: /students/joe/ vs. /facstaff/chip/ • Institutional vs. personal pages: /~jlevin/ vs. /deans/
