Measures of Spread: Range and Interquartile Range
Students will calculate the range and interquartile range (IQR) to describe the spread of data.
Key Questions
- Explain why the range only provides a limited view of data spread.
- Explain the significance of the interquartile range in understanding data distribution.
- Compare the effectiveness of range versus IQR in describing the spread of skewed data.
ACARA Content Descriptions
About This Topic
Exhibition Design focuses on the 'spatial' side of the arts. It's about how the physical or digital layout of a show guides the viewer's experience. In Year 8, students explore how lighting, wall color, text, and the 'flow' of a room can change how art is perceived. This topic aligns with ACARA standards by requiring students to consider the 'presentation' of their work and how it communicates with an audience.
Students learn that placing two artworks next to each other creates a 'conversation' between them. In the Australian context, this might involve looking at how First Nations art is displayed, often moving away from 'white cube' galleries to more culturally appropriate, immersive spaces. This topic is best taught through 'model building' and 'site visits' (real or virtual), where students can analyze how space influences their own emotions.
Active Learning Ideas
Inquiry Circle: The Flow Map
Using a floor plan of the classroom or a local gallery, students work in groups to 'draw the path' they want a viewer to take. They must mark where the 'climax' of the show is and where they will place 'breathing spaces' (empty walls).
Simulation Game: The Lighting Challenge
In a darkened room, students use torches to 'light' a single object in three different ways (e.g., spotlight, silhouette, wash). They discuss how each lighting choice changes the 'importance' and 'mood' of the object.
Think-Pair-Share: The Power of the Label
Show an abstract painting with no title. Students write their own 'wall text' for it. They then share with a partner how their text would change where the viewer looks and what they think the painting is about.
Watch Out for These Misconceptions
Common MisconceptionArt should always be hung at eye level.
What to Teach Instead
While 'eye level' is standard, hanging work very high or very low can create a specific psychological effect (e.g., making the viewer feel small or powerful). Experimenting with height helps students see this.
Common MisconceptionThe walls should always be white.
What to Teach Instead
Wall color can dramatically change the 'warmth' or 'vibrancy' of a work. Discussing why a gallery might use dark blue or earthy tones helps students see color as a design tool.

Planning templates for Mathematics
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
rubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
