Biology Question-Decoding Routine

Read. Decode. Rephrase. Predict. Respond. Check.

Use this before students answer a Biology question. The purpose is to separate knowing the topic from understanding what the question requires them to do with that knowledge.

How to use the routine

Model the six decisions with one original or authorised question, then ask students to use the thinking record before writing. The routine works best when the discussion focuses on why a decision matters, rather than whether every box has been filled.

Reduce the prompts as students become more independent. The goal is for the decisions to become quick and internal, not for the worksheet to become a permanent requirement.

  1. Read

    Read the whole question, including any data, figure, units and number of marks.

  2. Decode

    Identify the command word and the exact Biology idea the question is testing.

  3. Rephrase

    Put the question into your own words without changing what it asks you to do.

  4. Predict

    List the ideas, comparisons or causal links a complete answer will probably need.

  5. Respond

    Write the answer using precise Biology and a structure that matches the command word.

  6. Check

    Compare the answer with the original question: did you perform the task, or only write about the topic?
