Wading Through The Web

  1. 1. Wading through the Web Conducting Research on the Internet
  2. 2. Wading through the Web General Introduction This presentation will teach you about:  Different types of search engines  How to search on the Internet  How to cite your sources
  3. 3. Wading through the Web General Introduction
  4. 4. Wading through the Web General Introduction When might using the Internet be better than using a traditional text? Modern or contemporary topics – The Internet has more up-to-date information on current events. Controversial topics – The Internet can give you a lot of different opinions on one topic. It can help you research a topic from different perspectives.
  5. 5. Wading through the Web Different Types of Search Engines  A search engine is a program that allows you to search the Internet for information. You can find many different search engines on the Internet.  The most popular search engines are Google and Yahoo.  But there are many other excellent search engines that you may not have heard of.  Let’s look at some of those different search engines.
  6. 6. Wading through the Web Different Types of Search Engines Regular Search Engines vs. Metasearch Engines A regular search engine, like Google or Yahoo, searches the Internet based on a given search term.  For example, typing “Vasco da Gama” into Google will give you 3,220,000 hits or sites with information.  Type the same search term into Yahoo, and you get 9,500,000 hits. Try it! Go to Google and type in “Vasco da Gama.” Look at the sites that come up. Click on the first 2 or 3. Do they have good information? Now do the same in Yahoo. What differences do you notice?
  7. 7. Wading through the Web Different Types of Search Engines Why do Google and Yahoo display different sites for the same word?  They use different methods, called algorithms, to search the Internet. Many of the sites will be the same, but some will differ. A Metasearch engine can streamline your search, because it searches with several engines.
  8. 8. Wading through the Web Different Types of Search Engines Let’s try to use a Metasearch engine to find information on “Vasco da Gama.”  Cacti.com is a metasearch engine that searches Google, Yahoo, MSN, and Ask.com all at once.  Try it – Type in “Vasco da Gama at the Cacti.com site. The results are sorted by search engine. You can look at results by search engines or in combination.  How might a metasearch engine like this one be more helpful than a regular search engine?
  9. 9. Wading through the Web Different Types of Search Engines Other types of search engines can also be helpful. Let’s look at three different ones that can help you get better information. Clusty (formerly known as Vivisimo) groups search results by category. Try it – go to Clusty and type in “Vasco da Gama”. Notice the categories on the left-hand side of the page. You can use the categories to narrow your search. List the categories you might use to write a report on the life and accomplishments of Vasco da Gama.
  10. 10. Wading through the Web Different Types of Search Engines Answers.com (formerly known as Brainboost) allows you to type in a question rather than a search term. For example, if you wanted to know when Vasco da Gama reached India, you could ask a specific question and get more detailed information. Try it – Go to Answers.com and type “when did Vasco da Gama reach India?” How does the information that you get differ from the other search engines? What else do you notice about the left hand side of the page (and the right hand side as well)?
  11. 11. Wading through the Web Other Helpful Websites Other websites can provide good, refereed information for research projects.  On-line Encyclopedias can help. Try one of these: Encyclopedia Britannica or Encarta  School resource information is available at the TTSP Media Wiki. For these and other search engines, see Searching the Internet. For other resources, see Research Tools for Students.
