The Internet and the WWW
The Internet and the World Wide Web (also known as WWW or the Web) are not synonymous terms. The Web is built upon the internet. I think of it like a city being built on a parcel of land. The land itself is the structure for which the buildings, roads, sidewalks, houses, etc. are being built upon. They can be reconfigured as time goes on and it seems that although the buildings take up a large majority of the land, there are always other places that can be used for other things such as "Green" spaces or other uses.
One of the main uses for the Web that we have now is for information retrieval or better known as information searching. People use web browsers to use a variety of search engines in order to search for things they want to learn more about. Sometimes it is for business, sometimes it is for schoolwork, but sometimes it is just for entertainment. The problems we sometimes face are what search engines should we use. Most people will use a web-crawling search engine like Yahoo or Google. However, with the VAST amount of information that is out there those might not always give the best results.
In this module I will do a series of searches using a term(s) that is related to my area of initial certification, using a topic in my instructional design lesson plan I have put together. I will insert the term(s) as a keyword(s) in at least five different search tools. Using at least one tool from the Directory, Search Engine, and MetaSearch Engine categories. Below are the results of my activity.
The questions posted for this experiment are:
1 & 2. My search term was "classroom calculator use".
3. The top five sites from each engine was:
1. Yahoo:
4. They are not exactly the same sites for each search engine. There are some that repeat, but I thought it was interesting that the same search terms came back with mostly independent answers. It is also interesting that among the 5 search engines, Yahoo was the only one that offered a site to sell me calculators and IPL2 did more of a Boolean search and brought back the least helpful returns by using all the words instead of the words combined.
5. After reading up on search engines, and some prior knowledge on the issue, I understand that each search engine is built with certain algorithms to determine what it should search for and how it should rank the results. No one really understands what the algorithm settings are for each engine since they are proprietary it seems. There is also the idea of making the search results based on the users past history (more personal search returns). There is the possibility that if I were to do the same search on another person's computer that the results would be completely different than what I just received.

The questions posted for this experiment are:
- What were your Search term(s)? What Search Tools did you use
- How many hits did you get from each search tool?
- List the top five sites from each search tool.
- Are they the same sites?
- Are they in the same order?
- What do you attribute these finding to?
1 & 2. My search term was "classroom calculator use".
- Yahoo: 213,000,000
- Google: 3,520,000
- IXQuick: 165,999,719
- Bing: 97,800,000
