“Computers download information—• They do not teach you to think.• Computer education imparts

technical skills;• It does not impart knowledge.”• John Rosemond

Page 4: Internet 101

“Not all the information that exists in the world is on the Internet--

Not all the information that is on the Internet is accurate.”

An hour on the Web may not answer a question that you could find within two minutes of picking up a reference book.

Who Pays For The Internet?

• Advertisers pay for Internet websites.• Popups and banners are trying to influence your spending

habits.• The information on commercial sites--.com—may be presented

in such a way as to encourage you to buy a particular product.

• Be wary of URL’s with a ~ in the address—this indicates a personal homepage and does not guarnantee accuracy.

How Do You Find What You Need?• Libraries and department stores are planned.

• No one is in charge of organizing the Internet.

acronyms

Page 13: Internet 101

What Do You Use To Search?• Search engines

• Subject directories

• Subscription Databases

– Speciality Search engines

Page 14: Internet 101

Search Engines• Are like the index in the back of a book• Let you search for specific words and

topics• Use robots known as spiders to search

for information.

Page 15: Internet 101

Examples:• Google• Ask.com• Yahoo• MSN.com / Bing

Page 16: Internet 101

Subject Directories--

•Are like the table of contents in front of a book

•Let you search for concepts or subject categories

• Go from general to specific.

•Sites are added by people.

Page 17: Internet 101

Examples:• Internet Public Library• Yahooligans• KidsClick!• Fact Monster

Page 18: Internet 101

Instead of looking through the categories in a search directory, you can put in your terms in their search bar, but it will only look through the sites that have been included within that directory—not the entire web, unless indicated.

Page 19: Internet 101

Subscription Databases--• Paid subscription to web-based

reference tool with educational preference based on end user

• Filters built to select for education and students who use service

• Specialty Search engines are good for finding targeted items like pictures, maps, addresses…

Page 20: Internet 101

Examples:• New Book of Knowledge• Netrekker• Ebsco • Culture Grams

Specialty Search engine.. • Picture machine or map quest

Remember….• Hits are returned and ranked according to-- • How many times terms appear on the page• How often terms appear• How close terms are to each other• How near the top of the page the terms are found

• The best results will appear on the first page

• No two search engines are alike. Try another search engine, or rephrase your terms if you don’t get good results.

Page 22: Internet 101

More Searching Help--• Keywords (try using synomys)

• Combine important words

• Change the order of the words

• Try different websites depending on your information need

Evaluating Websites“Let the buyer beware”

Book publishers weed out inaccurate information.No one checks the Internet for accuracy.

Page 24: Internet 101

Before you start using the information--

EVALUATE!

Page 25: Internet 101

Who Made it? • What is the domain of the site?

• Is the information accurate? • Is the information current? • Is it relevant to your topic? • Is it well organized and easy to use?

Page 26: Internet 101

You leave “electronic footprints” wherever you go on the web.

•Good Information in•Means Good information
