Computer, level: Senior
Posted Mon Apr 30 11:49:33 PDT 2001 by Brenda (bbsieh@nvc.net).
Northern State Univeristy, Aberdeen, South Dakota USA
Materials Required: Computer, Internet, printer, whiteboard, school website and access to local Internet server
Activity Time: A week's worth of 50 minute lesson plans
Concepts Taught: Integrating OSI model

Unit 1
Review:
Each student will be able to answer/discuss the following
questions concerning:
1. What is computer networking?
2. What do we look for when dealing with reliable Internet sites?
Overview:
At the end of the lesson the student will be able to identify:
1. What computer networking is and what it entails.
2. What makes an Internet site reliable
Presentation:
1. Discuss computer networking and beginning of OSI model: Physical layer and what it encompasses (i.e. equipment, cables etc.). May point out on actual computer or use www.blackbox.com.
2. Discuss what makes an Internet site reliable and give worksheet to students to practice with five different Internet sites to develop a sense of reliability.
Exercise:
Teacher will demonstrate on computer where equipment is located both by computer and Internet site www.blackbox.com. Teacher will give handout on Internet reliability and then have students choose five websites to evaluate. After giving 15-20 minutes of working on the worksheet, students then stand up and give 3-5 minute presentation of one website that was evaluated.
Internet Reliability: Be a good judge of the WEB. Would you give the page a first place award?
Rate the Internet site you are using with the following scale. If it scores badly, find another place to get your information. For this exercise you must find FIVE sites to evaluate.
SITE:

1. Is there an author or sponsor of the page? Yes No
2. Are the author's credentials listed? Yes No
3. Is the author's affiliation listed? Yes No
4. Is contact information provided? Yes No
 (HINT: if a tilde (~) mark is used in the address that usually indicates a personal home page and may not be reliable.)
5. Has this page been updated recently? Yes No
Date updated ________________
6. Is the page well organized? Yes No
7. Is the site still under construction? Yes No
8. Is there a defined purpose for the page? Yes No
9. Is the information from the original source
(primary source) or a source reporting
about the original source(secondary source)? Yes No
10. Can you verify the information by using the
Links available? Do they take you where they should take you? Yes No
11. Are there any obvious biases? Yes No
12. Is there a copyright symbol on the page? Yes No

Total: Yes ____ No ____
Scoring:
1 to 5 "Yes" ----- Find another site to use. 6 to 8 "Yes" ----- The site may be worth looking into, but use caution. 10 to 12 "Yes" ----- You hit pay dirt and should find some useful information to use on this site

Unit 2
Review:
Each student will be able to answer/discuss the following questions concerning:
1. What is computer networking?
2. What do we remember about the OSI layer? Especially the physical layer?
3. Ask for current technology news events. (Will begin discussion on Unit 2 about current technology events that occurring in the region and around the world). May give tech-quiz if participation is not occurring. May also assign each student to a specific day and assign 3 events that have occurred in the day. May show websites to use:http://www.delphi.com/cbsbreakingnews/start/ and http://www.usatoday.com. Students would need to list from what website current events were taken from.
Overview:
At the end of the lesson the student will be able to identify:
1. What physical media is and what the types are (i.e. twisted pair, coaxial cable, fiber optic, guided, radio, infrared, microwave, satellite etc.).
2. What these words mean: domain name, IP address, worm, virus, byte, bit, protocols, token ring, Ethernet, routing, network, topology, error (control) etc.
Presentation:
1. Discuss in detail the OSI physical layer and media. Listing and describing each specifically. May use computer to demonstrate location and types of media or use www.blackbox.com. Encourage students to find different media Internet sites to use. May place each site on the board for quick reference or may place on school website. Allow 30 minutes for lecture and note taking.
2. Discuss vocabulary words that may appear frequently during computer networking discussions. Show the websites http://www.webopedia.com and http://www.techweb.com/encyclopedia. This may be included during note taking and lecture time.

Exercise:
Teacher will hand out worksheet that includes a word search for vocabulary words and also definitions to keep in notebooks for future reference. To create a word search the following website may be used http://www.edhelper.com
Using the following vocabulary words:
1. Byte -- equal to 8 bits
2. Bit -- smallest unit of information
3. NIC -- Network interface card
4. Worm -- replicates self through disk & memory
5. Virus -- software used to infect computer
6. Error control -- testing for accurate transmission of data
7. Fiberoptics -- made of light
8. Infra red -- invisible band of radiation
9. Physical layer -- provide transmission of bits over network medium
10. Protocol -- rules governing the transmission and receiving of data
11. Ethernet -- most widely used LAN
12. Routing -- forwards data to transmission
13. Topology -- pattern of interconnection
14. Domain -- all resources under the control of a single computer system
15. Address -- the number of a particular memory
16. Microwave -- vibrates at 1 Ghz and above
17. Twisted pair -- commonly used for telephone cabling
18. Technology -- implies the use of computers
19. Internet -- made up of over 65 million computers
20. FEC -- forward error control

Teacher will give an incentive for first student to find information on various websites when asked to recall vocabulary word (i.e. given candy for first to find what "worm" means) throughout the unit.

Unit 3
Review:
1. Student assigned with current events will present findings.
2. Each student will participate in discussion of last unit 2.
Overview:
At the end of the lesson the student will be able to identify:
1. What "ping" is and be able to demonstrate.
2. What trace route is and be able to demonstrate.
Presentation:
1. Discuss in detail the OSI data link layer. Listing and describing each specifically. Encourage students to find Internet sites to use to help in understanding material. May place each site on the board for quick reference or may place on school website. Allow 30 minutes for lecture and note taking.
2. Demonstrate how to use ping and trace route on MSDos and then copy to word.

Exercise:
Teacher will demonstrate ping and trace route and then give websites to ping and trace route to students. Five of each will be required to be handed in for completion of task.

2. Participate in discussion with school computer coordinator about school computer network.
Presentation:
1. Discuss in detail the OSI network layer. Listing and describing each specifically. Encourage students to find Internet sites to use to help in understanding material.
