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
![Page 9: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/9.jpg)
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
![Page 10: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/10.jpg)
The World-Wide Web
• A distributed hypermedia
• Different parts can be on different computers all around the world, with hypertextual links via the Internet
![Page 11: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/11.jpg)
Web surfing
• Web “surfing”– Advantages– Disadvantages
![Page 12: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/12.jpg)
Surfing to Serving
• Web Serving:– Advantages– Disadvantages
![Page 13: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/13.jpg)
Education and the web
• The Global Schoolnet web site– Harnessing the Power of the Web
![Page 14: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/14.jpg)
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
![Page 15: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/15.jpg)
Understanding URLs
• A unique address for each web resource
• Structure: what + which computer + which file
• Example: http://www.ed.uiuc.edu/courses/edpsy387/sp01/index.html
• What kind of resource: http:// -> Web file• Which computer: www.ed.uiuc.edu• Which file: courses/edpsy387/sp01/index.html
![Page 16: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/16.jpg)
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
![Page 17: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/17.jpg)
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://www.nsrc.org/codes/country-
codes.html
![Page 18: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/18.jpg)
Example:www.ed.uiuc.edu
• Next to the left: uiuc– University of Illinois, Urbana-Champaign
• Email example: [email protected]– Northwestern University
![Page 19: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/19.jpg)
Example: www.ed.uiuc.edu
• computers in the Education Building at UIUC
• www.beckman.uiuc.edu is a computer at the Beckman Institute
![Page 20: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/20.jpg)

![Page 21: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/21.jpg)
Sending/saving URLs
• Have to get the URL exactly right (sometimes case mAtTeRs; no spaces)
• Copy & paste is best
• Emailing a URL from your web browser– Advantages: can do anywhere– Disadvantages: need to set & then unset email
preferences
• Emailing yourself
![Page 22: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/22.jpg)
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: /deans/ vs. /~jlevin/
![Page 23: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/23.jpg)
Search Engines
• Yahoo & Open Directory: human classified databases of web sites

Digital Photo
• To be used (if you choose to do so) on your eportfolio web page or as your “signature” in WebBoard
![Page 26: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/26.jpg)
WebBoard
• A commercial web-based conferencing system
• Log in:
• Username: your net-id
• Password: your net-id (change it)
![Page 27: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/27.jpg)
C-Base

• Username: your net-id
• Password: your net-id (change it)
![Page 28: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/28.jpg)
Viruses & anti-virus software
• Computer viruses are little programs that replicate by attaching themselves to other programs
• Some viruses are “benign” (they don’t do much besides replicate); others do harm (deleting files, changing files, etc.)
![Page 29: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/29.jpg)
Anti-virus software
• Virex for the Macintosh
• Virus Scan for Windows 95/98
• Commercial, but licensed to you as students of UIUC and on your CD-ROM
• Need to obtain the update files at least monthly from the UIUC software site
![Page 30: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/30.jpg)
Virus hoax messages
• Any message that says “send this on to everyone you know” is probably a virus hoax message
• Before you do, check a reputable source - for example, http://www.symantec.com/avcenter/hoax.html
![Page 31: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/31.jpg)
“Macro” viruses
• Some applications allow for “macros” to automatically do repeated actions (for example, the Microsoft Office suite - MS Word, MS Excel, MS PowerPoint, MS Outlook)
• This “macro” mechanism can be used to create “macro viruses” which spread through documents (Word files, Outlook email, Excel spreadsheets)
![Page 32: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/32.jpg)
To avoid “macro viruses”
• Turn off the automatic running of macros
• Beware of files that ask to run macros when opened (“just say no”)
• Update your Windows MS Office applications
![Page 33: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/33.jpg)
Backup
• Backup means making copies of important files so they’re available in case you lose the original files
• The more important a file is, the more frequently it should be backed up and the more different places it should be copied to
![Page 34: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/34.jpg)
Backup
• Manual: copying individual files to floppy disks, zip disks, other hard disks, file servers, etc.
• Automatic: using an application that keeps track of what’s changed and therefore what needs to be copied at specified times
![Page 35: Welcome, EdPsy 387 students!](https://reader035.fdocuments.in/reader035/viewer/2022062422/56812d1b550346895d92133b/html5/thumbnails/35.jpg)
However
• Archival backup: keeping copies of older versions of your files that you keep around (forever? a year? …)
• If you make a change and only later discover that you’ve lost something, you can go back to an archival copy
• Periodic housekeeping: copy to floppy or zip disk; delete from local hard disk if not in current use
