Lesson Plan

• Describe the concept of batch processing and its key characteristics.
• Identify real‑world batch processing applications such as utility billing and payroll.
• Explain the sequential steps involved in batch processing for utility bills and payroll.
• Compare processing frequency, data volume, and typical software between the two applications.
• Apply the batch‑processing cycle to design a simple flowchart for a given scenario.

• Projector or interactive whiteboard
• Slide deck summarising batch processing
• Sample utility‑bill and payroll data sheets (printed)
• Comparison worksheet
• Flowchart template (paper or digital)
• Markers / pens

Begin with a quick poll: who has recently received an electricity bill or a payslip? Explain that behind these everyday documents lies a powerful batch‑processing system that runs without user interaction. Today we will explore how batch processing works, examine two common applications, and identify the steps that ensure accuracy and efficiency.

1. Do‑Now (5’) – Students list tasks they think could be automated in batches; share ideas.
2. Mini‑lecture (10’) – Definition of batch processing, key features, and why it’s used.
3. Case Study – Utility Bills (12’) – Walk through the four processing steps, discuss rate application.
4. Case Study – Payroll (12’) – Walk through payroll steps, highlight deductions and audit trail.
5. Comparison Activity (10’) – Groups fill a comparison table (frequency, volume, software) using the worksheet.
6. Flowchart Creation (8’) – Groups draft a simple batch‑processing flowchart for either utility billing or payroll.
7. Check for Understanding (3’) – Quick Q&A or exit ticket: “What is the main advantage of batch processing?”

Recap that batch processing enables large‑scale, repeatable calculations with consistency and speed. Ask students to write one key takeaway on a sticky note as an exit ticket. For homework, they should research another batch‑processing application (e.g., inventory update) and prepare a short description.
