Specifically, students should know the functions of the basic network devices (i.e. router, switch, NIC). Review of the Networking Terms Worksheet before the beginning of troubleshooting portion of the lesson is suggested. Introduction MI Introduction (LSI Quadrant I): SAY: Networks are used by large and small organizations. ASK: What would be a benefit of networking computers, printers, copiers, scanners together? SAY: Company resources can be used more efficiently without regard to location. (Example: Printers can be located in a building independently of a supporting computer, yet all computers on the same network can have access to it.)

SAY: World Wide organizations depend upon large networks for the success of their company. ASK: What would happen to such a company if their company network suddenly broke down? SAY: Knowing the basics of how a network functions allows a Network Administrator to solve problems as they arise. SAY: Today, we will observe a network which is not functioning due to one or more errors. Your lab assignment is to use standard troubleshooting techniques to determine those errors and then implement a solution. After the solution is complete, you will then test your solution to ensure a correct solution has been found. Outline MI Outline (LSI Quadrant II): I. Instructor Notes: Introduction to Networking A. Basic Networking Terms B. Basic Networking Concepts C. 3 types of Networking cables 1. Straight Thru 2. Crossover 3. Console II. Lab Setup A. Connect all equipment with proper cables B. Configure router and CPU’s with IP Addresses, Default Gateway Address, Network ID and Subnet Mask III. Input errors into the lab assignment A. Incorrect or damaged cables B. Incorrect Network ID C. Incorrect CPU configurations IV. Allow students, in groups, to analyze and determine error(s) in lab A. Use standard troubleshooting techniques B. Use cable testers C. Use CLI commands to test connectivity IT: Telecommunications and Networking: Broken LAN Plan Copyright © Texas Education Agency, 2013. All rights reserved. 3 V. After student groups have determined and repaired the error(s), then test the network to ensure lab is functioning VI. Students should fill out Lab Reports to summarize the entire lab experience Application MI Guided Practice (LSI Quadrant III): The teacher must first introduce detailed basic instruction on networking concepts and terms (utilize presentation). Then, students must be guided in the correct installation of equipment, as well as the configuration of each network device. MI Independent Practice (LSI Quadrant III): Students will work in groups (of no more than 3) in order to complete the lab. At the teacher’s discretion, each student in the group may be assigned a specific task to ensure all students’ participation in the lab. Summary MI Review (LSI Quadrants I and IV): Q: What were your initial ideas on determining the issue involved with the error(s) in your lab? Q: Once the issue had been determined, what were your steps, in order, to solve the problem? Q: If this were a company depending on a network to be profitable, what are the consequences of the network breaking down? Give specific, real company examples of your ideas. Evaluation MI Informal Assessment (LSI Quadrant III): Students should be evaluated at periodic intervals during the lab to ensure completion within the time allotment. MI Formal Assessment (LSI Quadrant III, IV): Students will be evaluated on their Lab Report Form, which must be typed and printed with correct spelling, grammar, and format (as per the teacher’s instructions).
