Lesson 1: Introduction: Command Words And Mark Schemes

Duration: 50 minutes

Starter Activity (5 minutes)

Quick Recall

3 quick questions to activate prior knowledge about command words and mark schemes. Use mini-whiteboard or paper.

Main Content (35 minutes)

Parent/Teacher Guide:
Before lesson: Read script below. Prepare materials. Pre-teach key vocab: key terminology for st1.
If stuck: See Troubleshooting below. Break into smaller steps.
Extension: See Stretch & Challenge section.
Teaching Script (35 mins):
Mins 0-5 - Hook: "Today: Command Words And Mark Schemes. Goal: deliver a st1 lesson confidently, addressing the key concepts and common misconceptions. Connects to prior learning in this subject because each lesson builds on the last, so revise the prior topic before starting."
Mins 5-15 - Direct Instruction: 1) Define: "Command Words And Mark Schemes is..." 2) Key principle: "Most important:..." 3) Draw diagram, label live. 4) Real example: "Like connect st1 to a real-world situation students recognise..."
Mins 15-25 - Guided Practice: Ex1: Teacher models. Ex2: Student tries with guidance. Ex3: Student independent.
Mins 25-35 - Independent Practice: 3-5 questions. Immediate feedback.
Worked Example 1: Basic

Q: A standard exam question on st1.

  1. What is asked? Explain
  2. Recall knowledge: The key facts about st1 from your revision notes.
  3. Apply: Work through the st1 method step by step, showing all reasoning.
  4. Check: Check units and sense-check your answer against what you expect.
  5. Answer: State the complete final answer with appropriate units or detail.

Tip: "Show working - method marks > answer marks."

Worked Example 2: Multi-step

Q: A multi-step question on st1.

  1. Break down: Separate parts?
  2. Solve each: Break the question into parts and solve each one, showing working.
  3. Combine: Each part feeds the next — chain your answers logically.
  4. Final answer: State the complete final answer to the multi-step question on st1.
Worked Example 3: Data/Application

Q: Interpret the data in the context of st1.

  1. Read data: Axes, units, scale
  2. Patterns: Trends, anomalies
  3. Explain: Why? Using command words and mark schemes
  4. Conclude: Evidence-based

Common Questions & Troubleshooting

Q: "Why does the core principle of st1 work this way?"
A: Analogy: "a comparison that makes st1 memorable". Try re-write the key points from memory, then check against the lesson notes.
Q: "Wrong answers on calculations."
A: Checklist: units? formula? calculator mode? sig figs?
Q: "Can't remember key terms."
A: Flashcards (term front, def+diagram back). Spaced repetition: day 1, 3, 7.
Q: "Exam wording confuses me."
A: Commands: Describe=what you see; Explain=reasons; Evaluate=pros/cons+judgement; Calculate=working+units.
Q: "Running out of time."
A: 1 mark/min. Skip hard, return. Attempt all - partial marks count.

Assessment Criteria

🎯 Examiner Insights

  • Timing: allocate 1 minute per mark — a 4-mark question gets 4 minutes.
  • Command words: "Explain" needs "because"; "Describe" needs factual detail; "Evaluate" needs both sides + a conclusion.
  • AO weighting: AO1 (recall) ~40%, AO2 (application) ~40%, AO3 (analysis) ~20% on most papers.
  • Common loss: candidates write correct science but don’t answer the question asked — re-read the stem before writing.
