Subject: Information Communication Technology ICT
Lesson Topic: Know and understand characteristics of analogue and digital data
Learning Objective/s:
  • Describe the key characteristics of analogue and digital data.
  • Compare analogue and digital signals in terms of continuity, noise sensitivity, and storage.
  • Explain how analogue‑to‑digital (ADC) and digital‑to‑analogue (DAC) conversion processes work.
  • Evaluate why digital data is preferred in modern ICT systems.
Materials Needed:
  • Projector and screen
  • Computer with presentation slides
  • Handout with analogue vs digital comparison table
  • Sample devices: microphone (analogue), digital camera, USB flash drive
  • Worksheet for group activity
  • Whiteboard and markers
 Introduction:
Begin with a short audio clip played through a microphone and the same clip shown as a digital file, asking students which format they think is easier to edit. Recall previous learning about binary numbers and how computers store information. Today’s success criteria: students will identify and compare the characteristics of analogue and digital data and explain conversion processes.
Lesson Structure:
  1. Do‑Now (5'): Students list examples of everyday analogue and digital items on sticky notes.
  2. Mini‑lecture (10'): Teacher presents key characteristics using slides and the comparison table.
  3. Demonstration (8'): Show ADC using a sound‑wave app and DAC by playing back the sampled audio.
  4. Group activity (12'): Teams fill a Venn diagram worksheet comparing analogue and digital data, then discuss.
  5. Check for understanding (5'): Quick quiz (Kahoot) with 5 questions on characteristics and conversion.
  6. Summary & exit ticket (5'): Students write one advantage of digital data on an index card.
Conclusion:
Review the main differences highlighted in the Venn diagram and the conversion demo. For the exit ticket, each student noted one benefit of digital data, confirming understanding. Assign homework to research a real‑world device that uses both analogue and digital components and prepare a brief description.
