Background and goal

Try the short introduction first, or bring equivalent reading experience. Obtain the specified text before beginning the longer reading.

Split a word-count script into reading, counting and reporting functions; explain each boundary.

Useful preparation

Start here if the background is new. Equivalent experience is enough.

    Answer this question in your own words: How can a small program be easier to change?

    Hint

    Name the claim, then explain why a reader might accept it.

    Compare with an example answer

    A named function groups a responsibility behind a clear input and output.

    What to look for

    • States a claim that addresses the question
    • Connects the claim to a passage or observation
    • Separates the author’s argument from personal agreement

    Common mistake: Summarising a biography instead of explaining the argument.

    What would make your activity a convincing example?

    Hint

    Split a word-count script into reading, counting and reporting functions; explain each boundary.

    Compare with an example answer

    A useful response carries out the task: Split a word-count script into reading, counting and reporting functions; explain each boundary. It records the observation or passage used and explains how it bears on the question.

    What to look for

    • Completes the specific task
    • Shows evidence or reasoning rather than only a conclusion
    • Identifies an alternative explanation or reading

    Common mistake: Presenting an opinion without showing the example it rests on.

    Reading notes and task
    Try thisWrite a response to “How can a small program be easier to change?” that uses both passages and tests its own conclusion. More functions do not automatically improve a design.
    Your outputReasoned response with references
    Check your understanding

    What is one conclusion this reading does not establish?

    Hint

    Test the boundary: More functions do not automatically improve a design.

    Compare with an example answer

    More functions do not automatically improve a design.

    What to look for

    • States a specific limit
    • Explains why the reading does not warrant the stronger conclusion
    • Distinguishes a limitation from dismissing the work

    Common mistake: Treating a useful interpretation as an unrestricted fact.
