Lesson Plan
Grade: Date: 17/01/2026
Subject: Computer Science
Lesson Topic: Explain the suitability of each method for a scenario
Learning Objective/s:
  • Describe the key characteristics of serial vs parallel, synchronous vs asynchronous, and simplex/half‑duplex/full‑duplex transmission.
  • Compare wired and wireless media in terms of speed, distance, cost and typical applications.
  • Evaluate which transmission type, media and protocol best fit a given real‑world scenario.
  • Apply a decision‑making framework to justify the chosen method for data transmission problems.
Materials Needed:
  • Projector and screen
  • Printed handouts of comparison tables
  • Laptop with internet access for demo videos
  • Worksheet with scenario‑matching tasks
  • Decision‑flowchart poster
  • Whiteboard and markers
 Introduction:
Begin with a quick poll: “What everyday devices rely on data transmission?” Connect to prior knowledge of cables and Wi‑Fi. Explain that today students will learn how to match transmission methods to specific needs and will be assessed on their ability to justify choices.
Lesson Structure:
  1. Do‑Now (5'): Students list three devices and the type of transmission they think each uses.
  2. Mini‑lecture (10'): Review serial/parallel, synchronous/asynchronous, duplex modes with the comparison tables.
  3. Media overview (10'): Show wired vs wireless media examples; discuss pros/cons.
  4. Scenario activity (15'): In pairs, students receive a scenario card and select the most suitable transmission type, media, and protocol, recording justification.
  5. Whole‑class debrief (10'): Pairs share choices; teacher highlights correct reasoning and common misconceptions.
  6. Decision‑flowchart practice (5'): Students place their scenario on the flowchart poster to visualise the selection process.
  7. Check for understanding (5'): Quick quiz (Kahoot/hand‑raise) on key distinctions.
Conclusion:
Recap the criteria used to match transmission methods to scenarios and ask students to summarise one key takeaway. Collect an exit ticket where each student writes the most appropriate method for a new scenario. Assign homework: create a short poster comparing two transmission media for a chosen application.
