Subject: Information Communication Technology ICT
Lesson Topic: Know and understand importance, characteristics and uses of verification including visual checking and double data entry to reduce data entry errors
Learning Objective/s:
  • Explain why verification is essential for data integrity.
  • Identify key characteristics of effective verification.
  • Compare visual checking and double data entry techniques.
  • Apply visual checking and double data entry to detect and correct data‑entry errors.
  • Evaluate which verification method is appropriate for different risk levels.
Materials Needed:
  • Projector and screen
  • Whiteboard and markers
  • Sample data sheets (paper and digital)
  • Laptops with spreadsheet software
  • Printed handout summarising verification techniques
  • Double‑entry comparison worksheet
 Introduction:
Begin with a quick poll: how many of you have entered data that later turned out to be wrong? Discuss how such errors can affect decisions. Today we will explore why verification matters, learn two key proofing methods, and you will demonstrate them to meet the success criteria of identifying characteristics, comparing techniques, and applying them correctly.
Lesson Structure:
  1. Do‑now (5') – students write down a recent mistake caused by bad data and share briefly.
  2. Mini‑lecture (10') – importance of verification and its key characteristics.
  3. Demonstration (10') – visual checking on a printed sheet versus the source document.
  4. Guided practice (15') – double data entry activity using laptops; pairs enter the same data set independently.
  5. Automated comparison (5') – run spreadsheet compare, discuss mismatches.
  6. Whole‑class discussion (10') – strengths/weaknesses of each technique and appropriate contexts.
  7. Exit ticket (5') – write one situation where double entry is essential and one where visual checking suffices.
Conclusion:
Recap the main points: verification protects decision‑making; visual checking is quick for small sets, while double entry catches most random errors. Complete the exit ticket and submit your worksheet. For homework, design a brief verification plan for a data‑entry task of your choice.
