Y08W30PA - The Adolescent Brain

This week you wrote an informative report explaining how the adolescent brain develops. Now you'll read another student's report and judge how strong it is. Working through how assessors evaluate informative writing builds your ability to apply the same lens to your own work.

Part 1

The Assessor Scorecard for

Informative – Informative report

Informative writing transforms complex information into understanding. The writer must select the most relevant material, organise it clearly, explain technical terms and show why the information matters.

Ideas & Content

Selection of the most relevant material — what helps a Year 8 reader. Deliberate choices about what to leave out. Clear explanations of why the information matters.

  • Selection: choosing what's most relevant and leaving out what's peripheral.

Structure & Cohesion

A shape that moves from general to specific, or simpler to more complex. A three-paragraph format that builds — topic, processes, implications. Transitions that help readers follow the thinking.

  • Logical progression: each paragraph builds on the previous one.

Audience & Purpose

Language pitched to Year 8 peers, not experts or parents. Examples drawn from real adolescent experience. Explanations that answer questions a teenager actually has.

  • Peer-relevant: information and examples that speak to Year 8 experience.

Language Choices

Technical terms — prefrontal cortex, limbic system — explained clearly. Analogies or simpler language used before jargon. Clear, active verbs throughout.

  • Clarity: technical terms explained; jargon avoided where simpler words work.

Conventions

Accurate information, correctly spelled — especially technical terms. Error-free conventions and clear paragraphing. Consistent tone and approach throughout.

  • Accuracy: correct information, error-free conventions.

Part 2

Today’s Marking Targets

Task in one sentence

Write an informative report explaining how the adolescent brain develops and what that means for behaviour and learning, in three paragraphs and your own words.

Let’s Focus

Three strands matter most this week: Ideas & Content, Structure & Cohesion and Language Choices. Ideas decides whether the writer selects the most relevant science. Structure decides whether the explanation builds clearly. Language decides whether technical ideas are accurate and understandable for the reader.

Ideas & Content

Strong writing this week shows careful selection. The writer has included the key ideas — adolescent development, prefrontal cortex maturing last, the timing gap with the limbic system. They've left out peripheral details and explained why the information matters.

What markers scan for

  • Inclusion of the key ideas about brain development and timing.
  • Explanations of technical terms tied to relevance.
  • Examples that speak to Year 8 experience.

Score Bands

  • Basic

    Includes some correct information but selection is unclear; may keep peripheral details or miss the timing difference between systems.

  • Strong

    Includes the key ideas with explanation; most peripheral detail is left out and the writing helps readers see why it matters.

  • Excellent

    Focused selection of the most relevant ideas; technical terms explained, timing shown clearly, examples relevant to adolescent experience.

Structure & Cohesion

Strong writing this week follows a logical explanatory sequence. The report should introduce the adolescent brain, explain the timing of development and then connect that development to behaviour and learning. Each paragraph needs a clear job so the reader can follow the science step by step.

What markers scan for

  • An opening that defines the topic clearly.
  • A logical order from brain development to behaviour and learning.
  • Topic sentences that signal each paragraph's focus.
  • Transitions that show cause and effect.

Score Bands

  • Basic

    Information is present but the order is unclear; ideas may feel listed rather than explained.

  • Strong

    The report is organised logically, with clear paragraphs that build understanding of development, behaviour and learning.

  • Excellent

    The structure is highly controlled; each paragraph builds on the previous one and guides the reader through a complex explanation smoothly.

Language Choices

Strong writing this week explains technical terms in clear Year 8 language. Words such as prefrontal cortex, impulse control and decision-making need to be accurate but not overloaded. The writer should translate science into meaning without making it childish or misleading.

What markers scan for

  • Technical terms introduced and explained in context.
  • Clear language that avoids copied textbook phrasing.
  • Examples that make brain development easier to understand.
  • Accurate word choices that do not oversimplify the science.

Score Bands

  • Basic

    Uses some technical words but does not always explain them; language may be vague or copied from notes.

  • Strong

    Explains most technical terms clearly and uses examples to help the reader understand adolescent brain development.

  • Excellent

    Uses precise, accessible language throughout; technical ideas are explained accurately and made meaningful for a Year 8 reader.

Student sample for assessment

Written by a Year 8 student in Coburg, Victoria, Australia.

Your brain is changing right now, and it's changing in ways that have a real effect on how you think, learn and make decisions. Unlike most parts of your body, your brain doesn't finish developing until you're in your mid-twenties. The parts that keep developing through your teenage years aren't random—they're the parts that matter most for learning, decision-making and understanding risk. Understanding what's happening can help you understand yourself. The key to understanding adolescent development is timing. Your brain has two main systems: the limbic system, which processes emotions and rewards, and the prefrontal cortex, which handles decision-making, planning and impulse control. Here's what makes adolescence tricky: the limbic system develops earlier than the prefrontal cortex. So during your teenage years, you have a brain that's very responsive to emotions and rewards—sometimes intensely responsive—but the part of your brain that usually keeps that intensity in check is still under construction. This timing gap is thought to explain why teenagers often take risks, feel emotions intensely and care so much about what their peers think. It's not a character flaw; it's neurobiology. What does this mean for you right now? First, it means your brain is highly adaptable. You can learn new skills and ideas faster than almost anyone else. Second, it means that what you do during these years—exercise, sleep, managing stress—actually shapes how your brain develops. Good sleep helps your memory consolidate; exercise supports healthy development; stress can affect the way your brain changes. You're not stuck with however your brain is now. You're actively shaping how it grows. That's both a responsibility and an opportunity.
