Instructional Objectives

At the end of the lesson, pupils should be able to:

1. Identify the different generations of computers and their characteristics.
2. Explain the major developments in each computer generation.
3. Describe the impact of these developments on modern computing.

Entry Behaviour

Pupils should already know the basic parts of a computer (monitor, keyboard, mouse, CPU) and their primary functions.

Content

Introduction

Generational Development of Computers

Various Stages in Computer Development

1. First Generation (1940-1956): Vacuum Tubes
   • Large size, consumed a lot of power, used punch cards.
   • Example: ENIAC
2. Second Generation (1956-1963): Transistors
   • Smaller, faster, more reliable, used assembly language.
   • Example: IBM 7094
3. Third Generation (1964-1971): Integrated Circuits
   • Smaller, more efficient, used high-level programming languages.
   • Example: IBM 360
4. Fourth Generation (1971-Present): Microprocessors
   • Very small, powerful, personal computers, development of GUIs.
   • Example: Intel 4004
5. Fifth Generation (Present and Beyond): Artificial Intelligence
   • Based on AI, advanced parallel processing, use of quantum computation.
   • Example: IBM Watson

Lesson Presentation (Step-by-Step Procedure)

Step 1: Introduction

• Start with a story about how computers have evolved from large machines to the small devices we use today. Ask pupils if they know how computers were different in the past.

Step 2: Explanation

• Explain the five generations of computers, using simple language and examples. Show visual aids of each generation.

Step 3: Demonstration

• Use flashcards to demonstrate key terms and images related to each computer generation. Show how each generation improved on the previous one.

Step 4: Guided Practice

• Engage pupils in a matching activity where they match descriptions of each computer generation with the correct images and key terms.

Step 5: Independent Practice

• Provide a worksheet where pupils label parts of computers from different generations and write a short description of each.

Step 6: Feedback

• Review the worksheets with the pupils, providing feedback and clarifying any misconceptions. Reinforce key points about each generatio

Evaluation

Formative Assessment:

• Observe pupils during guided practice to ensure they understand the differences between each generation.
• Ask questions throughout the lesson to gauge understanding.

Summative Assessment:

• At the end of the lesson, have pupils complete a short quiz where they match characteristics to the correct computer generation and describe one major development from each.

Summary/Conclusion

• Summarize the key points about the five generations of computers and their impact on modern computing. Answer any remaining questions from the pupils.
