Lesson Plan for J.S.S 1 (Age 11)
Subject: Computer Studies
Class: J.S.S One
Week of the Third Term: 1st Week
Topic: The Monitor
Sub-topic: Definition of Computer Monitor, Description of a Monitor as an Output Device, Types of Monitor: Monochrome Monitor, Color Monitor
Instructional Objectives
At the end of the lesson, students should be able to:
- Define a computer monitor and describe its primary function as an output device.
- Differentiate between monochrome and color monitors.
- Identify real-world applications where each type of monitor might be used.
Entry Behaviour
Students should already be familiar with the basic parts of a computer and understand the concept of input and output devices.
Instructional Materials
- Textbook: “Computer Studies for Senior Secondary Schools”
- Visual aids showing different types of monitors (monochrome and color)
- Flashcards with definitions and images of monitor types

Content
Definition of a Computer Monitor
A computer monitor is a screen that displays the output from a computer. It allows users to see the information being processed by the computer, such as text, images, videos, and graphics. Essentially, it is a device that allows us to view what the computer is doing.
Description of a Monitor as an Output Device
A computer monitor is classified as an output device. This means that it takes information from the computer and presents it to the user. Unlike input devices (like a keyboard or mouse), which send data into the computer, output devices like monitors show the results of the computer’s processing. When you type on the keyboard or click on the mouse, the monitor shows what happens in response to these actions.
Types of Monitors
A monochrome monitor displays images in only one color, usually black and white. These monitors are capable of showing text and simple graphics but are limited in terms of color variety. Monochrome monitors were common in older computer systems, especially in the early days of personal computing.
A colour monitor displays images in a range of colors. This type of monitor provides richer graphics and is used in modern computing for tasks like watching videos, playing games, and designing graphics. Color monitors are capable of displaying millions of colors, making them essential for applications that require detailed visual output, such as image editing or multimedia work.
Lesson Presentation (Step-by-Step Procedure)
Step 1: Introduction
- Engage students by asking them to look around the classroom and identify any output devices they see. Guide the conversation toward the monitor, asking how it differs from other output devices.
Step 2: Explanation
- Explain the function of the monitor as an output device, defining its role in displaying processed information. Introduce the concepts of monochrome and color monitors, explaining their differences and typical applications.
Step 3: Demonstration
- Show students visual aids of both monochrome and color monitors. If possible, display images on a projector or physical examples, if available, to demonstrate the difference in display styles.
Step 4: Guided Practice
- In groups, have students discuss and list environments where monochrome monitors or color monitors might be useful (e.g., in hospitals, art studios, gaming).
Step 5: Independent Practice
- Ask students to write down the definition of a monitor and describe one key difference between monochrome and color monitors in their own words.
Step 6: Feedback
- Review students’ definitions and descriptions, addressing any misconceptions. Reinforce the differences between the types of monitors.
Evaluation
- Formative Assessment:
- Ask questions throughout the lesson, such as, “What is an output device?” and “How does a color monitor differ from a monochrome monitor?” to assess understanding.
- Summative Assessment:
- At the end of the lesson, administer a short quiz on monitor definitions and types.
Summary/Conclusion
- Summarize the lesson by highlighting the role of the monitor as an output device, and review the differences between monochrome and color monitors. Emphasize where each type might be used in real life.
Assignment
- Have students research and write a short paragraph about a place or device in the real world where they think a monochrome or color monitor would be most effective, explaining why they chose that example.
