Students should understand each objective. As you cover material in the chapter. you may want to refer back to the slides.
The Internet has been around --30 years. You should speak with your students about exciting places they will visit, the foundations of the WWW, and how the WWW works on a server/client model. A URL is required, and for a document to contain hypertext and/or hypermedia it must have the HyperText Transfer Protocol. A browser is required to read HTML documents. HTML is the language of the Web.
HTTP: Hypertext Transfer Protocol - used to transmit Web documents. HTTPS: Hypertext Transfer Protocol Secured - used to transmit secured Web documents. HTML: Hypertext Markup Language – used to create documents that can be read by Web browsers. ISP: Internet Service Provider - needed to connect to the Internet. URL: Uniform Resource Locator: WWW address for finding information on the Web. URL format: .edu, .gov, .com, .org Discuss the differences between HTTP and HTTPS, and explain that cookies are written to the users disk each time a user visits a site.

Most students should find searching the net a pleasant exercise. Use these objectives to reinforce this search process. Explain that all search engines, while similar in query building, have different databases and specialties. Searching is more of an art; however, the more you do the better you will become. You should emphasize that most students will not become Web designers, but learning how to search the Web effectively will benefit them. Students should understand what a URL means and how to use the Save As and Find Commands. A search engine is an amazing tool. It uses the student’s choice of keywords and Boolean operators to establish a search. It is important to understand that since all search engines have different databases and use different logical operators, the answers will differ—so use multiple search engines. The documents returned are referred to as hits. A Query is a word(s) or phrase, looking for documents on a specific topic. A Search Form is where you enter key words or phrases. A Site Search searches a specific site. Hits are returned from a search. Students can use an AutoSearch by entering a key word in the Address box then typing “go”. The Net Search button gives you easy access to multiple search engines—five prominent ones, but also some others if you scroll down in Net Search.
Use this opportunity to explain the differences between keyword searches and category searches. Categories are helpful if your topic is ambiguous. The status bar will keep you informed of your progress. Again, let students understand that searching is more of an art than a science, but understanding the use of Boolean operators used in library science is crucial to getting good and quick results. The Boolean operators are And, Not, and Or, and each search engine sets up their own Boolean structure. Emphasize to always use multiple search engines and to read about the search process provided by each search engine. Explain how the Find command is to help move around in lengthy Web pages. Understanding what a URL is and how it is structured will help students when they get stuck. For example, knowing that a server is often the name of the company or organization allows you to go directly to the URL without searching. Understanding that a URL can be peeled back until you reach the home page is also useful. Learning about searching for a concept is important because it may relate information you were not thinking about. Often students want to be able to save the information they find because they cannot use Favorites in a lab situation. Discuss using the right mouse button for Saving both graphics and files. The selection of Favorites is useful to students in home situations; suggest that as an alternative to saving.
Copyright provides legal protection to a written or artistic work, giving the author exclusive rights to its use and reproduction. Public domain means that everyone can freely reproduce and distribute the work. The Fair Use exclusion is used for educational, non-profit purposes, or for the purpose of critical review or commentary that does not violate copyright laws. A footnote can be inserted into a document and may include information about the original source of a quoted or copied work. A footnote appears at the bottom of the page where the reference occurs. An endnote could also contain information about the original source of a quoted or copied work. An endnote appears at the end of a document.
Perhaps one of the most important concepts for students is the copyright infringement issue.
Web pages can easily be created in Word. You may want to show students how quickly a Web page can be created in Word, by typing some text and using the Save As Web Page command.
