A. Computer Ethics Computer ethics refers to the moral principles that govern the use of computers. It involves making responsible decisions about how to use technology to avoid harm, respect others' rights, and ensure fair and appropriate access to computing resources. In a school setting, computer ethics primarily focuses on the responsible use and care of shared computer equipment and facilities. B. Ways of Taking Good Care of a Computer Room/Laboratory Proper care of a computer laboratory is essential to ensure its longevity, optimal performance, and safety for all users.
This involves several aspects:
1. Environmental Control: Temperature and Ventilation: Computers generate heat and require a cool, well-ventilated environment to prevent overheating. The room should have adequate fans, air conditioners, or cross-ventilation. Extreme heat can damage internal components.
Dust Control: Dust is a major enemy of computers. It can clog cooling fans, cause components to overheat, and lead to short circuits. The room should be regularly cleaned with damp cloths (not wet) and anti-static cleaners. Computer covers should be used when systems are not in use, especially in dusty Nigerian environments.
Moisture Control: Water or any liquid spills can cause severe damage to electronic components and pose electrical hazards. No food or drinks should be allowed near computers. The room should be free from leaks.
Power Stability: Unstable power supply (fluctuations, power surges, outages) can damage computers. A computer laboratory should be equipped with: Uninterruptible Power Supply (UPS): Provides temporary power during outages, allowing for proper shutdown.
Voltage Stabilizers: Protects against power fluctuations.
Proper Earthing: Essential for electrical safety.
2. Physical Handling and Maintenance: Gentle Handling: Students should be taught to handle keyboards, mice, monitors, and system units gently. Avoid dropping, banging, or forcefully pressing keys/buttons.
Cleanliness: Wipe screens with a soft, lint-free cloth, ideally with a screen cleaning solution. Use compressed air to clean dust from keyboards and vents. Clean mice and mouse pads regularly. Keep the entire room tidy, with chairs tucked in and cables neatly arranged.
Proper Shutdown: Always shut down computers properly using the operating system's shutdown procedure (e.g., Start Menu > Power > Shut Down). Abrupt power cuts can corrupt files and damage the operating system or hardware.
Cable Management: Ensure all cables (power, network, peripheral) are neatly arranged, not tangled, and not posing tripping hazards. Damaged cables should be reported immediately.
Reporting Faults: Any observed fault, no matter how minor (e.g., a loose cable, a non-responsive mouse, strange noises), should be immediately reported to the teacher or lab attendant. This prevents further damage and ensures timely repairs.
3. Software and Security Care: Anti-virus Software: Ensure all computers have up-to-date anti-virus software to protect against malware that can slow down systems, corrupt data, or steal information.
No Unauthorized Software: Students should not install or uninstall any software without permission. This prevents the introduction of viruses, illegal software, or software that may interfere with other programs.
Data Backup: Important data on shared computers should be regularly backed up to external drives or network storage to prevent loss in case of system failure. C. Rules and Regulations of a Computer Laboratory These are specific guidelines designed to ensure safety, order, fair usage, and the preservation of equipment within a computer laboratory.
Typical rules include:
1. Entry and Exit: Enter and exit quietly and orderly. Do not enter the lab without the teacher's permission or supervision. Sign in and out of the lab if a logbook is provided. Do not bring unauthorized visitors into the lab.

Worked Example for Concepts: Scenario: A student named Chijioke is using a computer in the lab and notices the monitor screen is dusty. Another student, Amaka, is about to bring a bottle of soft drink into the lab.
Application of Concepts: Care for Equipment (Dust): Chijioke should inform the teacher or lab attendant about the dust, or if permitted, gently wipe the screen with a dry, soft, lint-free cloth (not a wet one). He should not spray liquid directly onto the screen or use a rough material. * Lab Rules (Drinks): Amaka should be reminded that bringing drinks into the computer lab is against the rules because a spill could permanently damage the computer and create an electrical hazard. She should either finish her drink outside or leave it outside the lab.
Phase 1: Introduction (10 minutes)
Teacher Activity: Greets students and briefly reviews previous topic (e.g., components of a computer if covered recently). Introduces "Computer Ethics" by asking students what they think "ethics" means in general terms, then narrows it down to computers and their use in a shared environment like their school lab. Highlights the importance of responsible computer use for safety, equipment longevity, and efficient learning, linking it to their school's computer lab as a valuable resource. States the learning objectives for the lesson clearly.
Student Activity: Respond to review questions and participate in a brief discussion on "ethics." Listen attentively to the introduction and learning objectives.
Phase 2: Concept Exploration and Explanation (25 minutes)
Teacher Activity: Begins by explaining "Ways of Taking Good Care of a Computer Room/Laboratory." Uses a whiteboard or projector to list points under categories like "Environmental Control," "Physical Handling," and "Software/Security Care." For each point (e.g., "dust control," "no food/drinks," "proper shutdown"), explains its importance, potential consequences if neglected, and demonstrates correct procedures where feasible (e.g., showing a proper shutdown sequence on a lab computer).
Uses Nigerian examples: "Imagine dust from harmattan season getting into the CPU," "What happens if Nepa takes light abruptly without a UPS?" Transitions to "Rules and Regulations of a Computer Laboratory." Facilitates a brainstorming session: "What rules do you think should be in place in our computer lab?" Compares student suggestions with a comprehensive list of typical rules, explaining the rationale behind each (e.g., "Why no food?," "Why report faults immediately?"). Categorizes rules into "Entry/Exit," "Usage," "Respect/Security." Student Activity: Take notes as the teacher explains. Participate actively in the brainstorming session, suggesting rules based on their understanding and experiences. Ask clarifying questions. Observe teacher demonstrations of proper computer handling and shutdown.
Phase 3: Group Activity / Application (15 minutes)
Teacher Activity: Divides students into small groups (e.g., 4-5 students per group).
Assigns a task: "Each group will create a short poster or list of 5-7 essential rules for our school's computer laboratory, including reasons why each rule is important." Circulates among groups, providing guidance, clarifying misconceptions, and ensuring all students are participating. Encourages groups to think about rules relevant to their specific school context (e.g., limited power, shared equipment).
Student Activity: Collaborate within their groups to discuss and agree on key rules. Design a poster or write down their list of rules and their justifications. Prepare to present their work to the class.
Phase 4: Presentation and Conclusion (10 minutes)
Teacher Activity: Invites a representative from each group to briefly present their chosen rules and justifications. Provides constructive feedback, highlights common good points, and clarifies any misunderstandings. Summarizes the key takeaways of the lesson, re-emphasizing the importance of computer ethics for safety, longevity of equipment, and effective learning. Checks for understanding through quick questions.
