Web+Literacy+3



=**Lesson 3 : Search Engines**=


 * Aim:**

How do search engines work?


 * Common Core State Standards:**


 * CCSS.ELA-Literacy.W.11-12.7** Conduct short as well as more sustained research projects to answer a question (including a self-generated question) or solve a problem; narrow or broaden the inquiry when appropriate; synthesize multiple sources on the subject, demonstrating understanding of the subject under investigation.


 * CCSS.ELA-Literacy.W.11-12.8** Gather relevant information from multiple authoritative print and digital sources, using advanced searches effectively; assess the strengths and limitations of each source in terms of the task, purpose, and audience; integrate information into the text selectively to maintain the flow of ideas, avoiding plagiarism and overreliance on any one source and following a standard format for citation.


 * NETS Standards ** (From ISTE International Society for Technology in Education)

1) Create a new page on your wiki and name it Web Literacy 3 with today's date.

2) Go to the Web site next to your name below and describe what you think the purpose of this Web site is and why/how you would use it. Perform a search in the site's search box and then compare it to a Google search by doing the same search in Google.

Answer these questions in a table on your wiki:

perform the same search in Google. Did you get the same results? ||  ||

 * Class Activity 2:**

1) Create a new page on your wiki and name it Web Literacy 3 with today's date.

2) Go to NoodleTools, which helps you choose the best search for your information needs, and NoodleQuest, which is an interactive version of the one listed above.

Think of a topic you are studying in school. Has your teacher assigned anything yet, like an essay or a research paper? Search for that topic or make up something you are interested in, such as animal rights, gun control, bullying, etc. Take a look at NoodleTools Advice Engine and then go to NoodleQuest and answer the questions, then look at the results that NoodleQuest suggests. Do you think it was helpful? Would you consider using NoodleQuest before you do your next Internet search?


 * Class Activity 3:**

1) On your same Web Literacy 3 page, create a table like the one below and answer the following:

2) Go to each of the following Google search engines:


 * @http://www.google.com
 * @http://www.google.co.uk
 * @http://www.google.com.au
 * @http://www.google.co.nz
 * @http://www.google.co.za
 * @http://www.google.ca
 * @http://google.ie
 * @http://google.com.br
 * @http://google.es
 * @http://google.se
 * @http://google.de
 * @http://google.fr
 * @http://google.it
 * @http://google.dk
 * @http://google.fi
 * @http://google.no
 * @http://google.gr
 * @http://google.jp
 * @http://google.com.hk
 * @http://google.ru
 * @http://google.pt
 * @http://google.ch

3) Perform a search on a search term of your choosing on each of the above Google sites. Although the first seven of these Google sites is in English, you should see different results as each is in a different country. Look for the ccTLD in the URL for the country code top level domain. For example, Google New Zealand should have results with .nz somewhere in the domain name. List 1 result for each site for the keyword you are searching. You can simply go to the link and cut and paste it into your wiki table. Answer this question: How are the results different for each of the different Google search engines?


 * **Google Site** || **Search Term** || **One result** ||
 * google.com || dogs || www.nycyorkie.com ||
 * google.co.uk || dogs || guidedogs.org.uk ||
 * google.com.au || dogs || dogsnsw.org.au ||
 * google.co.nz || dogs || dogsafety.govt.nz ||
 * google.co.za || dogs || guidedog.org.za ||
 * google.ca || dogs || ottawahumane.ca ||


 * Class Activity 4: **

1) Go to:


 * @http://dogpile.com
 * @http://webcrawler.com
 * @http://monstercrawler.com
 * @http://mamma.com
 * @http://ixquick.com
 * @http://metacrawler.com
 * @http://yippy.com
 * @http://deeperweb.com/
 * @http://msxml.excite.com/
 * @http://www.hotbot.com/
 * @http://www.info.com/

and perform a search in each meta-search engine. Do the same search in Google and compare your results. Answer these questions: Did you get the same results in the meta-search engine as you did in Google? How do the results compare? Fill in your answers in a form that should look like the one below and answer the above questions at the bottom of the table.


 * **Topic** || **Meta-Search Engine Used** || **Meta-Search Engine Results** || **Google Results** ||
 * Animal Rights || Dogpile || 1,034,450 || 1,175,000,000 ||
 * Animal Rights || WebCrawler ||  ||   ||

Who Controls Information on the Internet?

You should use more than one search engine when you do your research. You should also look past the top results. Given the same keyword search, different search engines rank sites differently according to their own search algorithm. Are the top results in one search engine “better” than another? You decide. In this exercise, you will search the same keyword in four different search engines (Yahoo!, Ask, Google, and Bing) and record the top five results for each, plus count the number of paid listings per each search, and answer these questions on your wiki:


 * Compare and contrast the results from the various engines. Can you make any generalizations?
 * Did some search engines seem to have more paid listings than others? If so, which ones?
 * Which search engines might you be more likely to use and why?
 * How might using more than one search engine when researching information help you find better information?
 * What conclusions can you draw about researching information on the Internet?
 * What is your keyword?

 * Summary Activity: **

Go here: **@http://padlet.com/psarles/exitticket3** and answer the questions.


 * Homework:**

1) What is your favorite search engine and why?

2) How does the purchase of keywords affect the results of your searches in search engines?

3) Because people can purchase keywords, do you believe the Internet could influence how people vote?

4) When using the same search engine around the world, you can see very different results with the same search phrases, such as "global warming" or "Tibet." What impact do you think this will have on global understanding? For example, when you search an engine in a different country, what do the different results teach you about that country?
