2 Preparing To Search The Internet

3 Surfing is not searching.

4 “ Computers download information — They do not teach you to think. Computer education imparts technical skills; It does not impart knowledge. ” John Rosemond

5 “Not all the information that exists in the world is on the Internet-- Not all the information that is on the Internet is accurate.” Mrs. Kotsch

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

7 Getting Started Searching URL ’ s Searching techniques Search engines

8 URL ’ s Uniform Resource Locator The web “ address ” that connects you with a website Goes in the address bar at the top of the screen Gives you information about the website

9 Parts of a URL http://www.starwars.com/seminars.html http://--hypertext transfer protocol: the language computers use to “ talk ” to one another www — world wide web: the body of information connected by the cables and computers of the Internet.starwars — domain name: the structured, alphabetic-based, unique name for a computer on a network.com — top level domain: gives an idea of where the document is stored /seminars — file name: a folder within a website.html — hypertext markup language: the computer language used to format documents

10 Top Level Domains.edu — higher education.k-12 — elementary and secondary schools.com — commercial.gov — government agency.mil — military.org — general noncommercial organization.net — computer network

11 Who Pays For The Internet? Advertisers pay for Internet websites. Pop-ups 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 guarantee accuracy.

12 How Do You Find What You Need? Libraries and department stores are planned. No one is in charge of organizing the Internet. Well-prepared searches will eliminate useless hits and wasted time.

13 Before you search, you need to: Prepare Organize Combine - Boolean

14 Prepare What do you need to know about your topic? Make a list of all the terms connected with your topic. Include names, organizations, and phrases.

15 Organize Make a list of the words that are critical to your search. Note terms that you don ’ t want to see appear. Discard the rest.

16 For example… If you are looking for information about life on the planet Mars, you don’t want sites popping up about the Roman god of war. Put that in your list of words you don’t want to see. What other words might be connected with your topic that will send you to useless sites?

17 Combine Use Boolean operators to combine your most important terms. Use AND to connect the terms you want to see. Use NOT to exclude terms you don ’ t want. Use OR to include similar terms. Use quotation marks around names or phrases Use lower case for all proper nouns, except for acronyms

18 For example… mars AND planet AND life NOT god

19 But what if… you WERE looking for information about the Roman god of war? The Greeks referred to him as “Ares”, so now your search will look like this….

20 mars OR ares AND “ god of war ” Notice the quotation marks around the phrase “god of war”

21 What Do You Use To Search? Search engines Search directories Metasearch engines

22 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.

23 Examples: Google Alta Vista Excite Hotbot Infoseek Ask

24 Search 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

25 Examples: Yahoo Librarians ’ index Internet Public Library About

26 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.

27 Metasearch engines-- Sends your search terms to several other search engines at once. Gives an overview of a topic across the Internet.

28 Examples: Webcrawler Dogpile Metacrawler Mamma

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

30 Evaluating Websites “ Let the buyer beware ” Book publishers weed out inaccurate information. No one checks the Internet for accuracy.

31 Before you start using the information-- EVALUATE!

32 Who is the author? Is he an authority on the subject? Does she have an e-mail address?

33 Is the information accurate? Can it be verified in an encyclopedia? Is it relevant to your topic? Does the author indicate where he found the information?

34 Is the information prejudiced? Is it trying to persuade you to another point of view? Is it trying to persuade you to buy a product?

35 Is the information current? When was the last time the website was updated? Are the links broken?

36 Evaluation Website Quality Information Checklist 5W ’ s of Web Site Evaluation Examples: Benefits of Colloidal Silver Burger King Introduces…Burger King Introduces

37 Copyright Issues What can you copy? Give credit to what you have used.

38 Copyright Is the legal right of an author or artist to control the copying and use of their creative works. Taking something without permission is theft, including text and pictures from the Internet. Using someone else ’ s words without giving credit is called plagiarism. “ Fair Dealing ” concept lets teachers and students use portions of copyrighted works without permission.

39 What is protected by copyright? Literary works Computer software Musical works Dramatic works Motion pictures Sound recordings

40 Before you copy, check the Fair Dealing Guidelines: Am I using this for a nonprofit, educational purpose? Am I only using a small portion? Will the creator be deprived of future profits?

41 What can students copy? you can copy up to 10 or 15 per cent of a work operiodical article (1 article per issue) onewspaper article oshort story, play, or poem from a book oentire chapter of a book (up to 20% of the entire book) oentire entry from a reference work material found on the Internet is protected by copyright ousing text, images, video or audio material, you need to obtain permission from the owner (normally the person or organization who created the material) to use it. oseek permission using the Webmaster ’ s e-mail Students must cite the source of their information

43 Citing a website Last name, first name of author. –If there is no author listed, begin with the title. “ Title of article within the website. ” –Put quote marks around the title Name of website. –Underline the name Date article was written. –Put the date first, then abbreviate the month. Date you accessed the article. URL. –If the URL won ’ t fit on one line, break it at a slash. Include the entire URL, not just the one for the home page.

46 Staying Safe On-line Don ’ t give out personal information. –(phone number, address, pictures) Use courtesy in e-mails and chat rooms. Don ’ t arrange to meet with someone from online without telling your parents. Do tell your parents about inappropriate websites that you run across. Be careful what you post in a public forum. *

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