Learner
1. Students should refer to the curriculum material in the presentation and the class notes for definitions, instructions, and concepts regarding computer disaster recovery and preventative maintenance.
Introduction
MI Introduction (LSI Quadrant I):

Ask, "What types of negative experiences have you had with computers?
”

Ask, "Have you ever experienced a catastrophic computer malfunction?"

Ask, "What was the outcome and what did you learn from it?"

Say, "In this lesson, we are going to discuss the implementation of a disaster recovery plan for events such as these, and we will learn how to perform preventative maintenance to protect your computer and your data."

MI
The teacher will define and review measures necessary for preventative maintenance and discuss why it is recommended.
Groups will discuss three or more preventative measures that can be taken to protect the computer and the data on the computer. The groups will detail those measures in writing. They will then pick one of the preventative measures they chose and demonstrate it to their peers on the computer at the front of the classroom.
Independent Practice (LSI Quadrant III):
The student will detail the recovery plan for a personal computer in his/her home. This plan must encompass everything covered in the presentation.
He/she must print this and post it by a computer at home. He/she must turn in a copy of the written plan and may optionally turn in a photo of the plan posted by his/her home computer.
Summary

MI
MI
Review (LSI Quadrants I and IV):
Ask the students these questions.
1. "What is a disaster recovery plan?"
2. "What is the purpose behind a disaster recovery plan?"
3. "Name some of the negative effects for not having a disaster
recovery plan."
4. "What is preventative maintenance?"
5. "How can preventative maintenance help prolong a computer’s life expectancy?"
Evaluation
Informal Assessment (LSI Quadrant III):
The instructor will monitor student progress during the independent practice and answer questions groups may have as they practice both preventative maintenance and disaster recovery measures.
Formal Assessment (LSI Quadrant III, IV):
The instructor will administer the Computer Troubleshooting and Repair
Process Exam and grade it with the exam key.
MI
Extension
Extension/Enrichment (LSI Quadrant IV):
The students will practice using the preventative maintenance procedures on a friend or family member’s computer. They will give a detailed report of the measures they took and have the report signed by the owner of the computer.
