Measures of Spread (Range, IQR)

Students will calculate and interpret the range and interquartile range (IQR) as measures of data spread.

Key Questions

  1. What does the spread of the interquartile range tell us about the consistency of a data set?
  2. Compare the range and IQR as measures of spread, highlighting their advantages and disadvantages.
  3. Predict how adding an outlier affects the range and IQR of a data set.

About This Topic

Post-Modernism and the Death of the Artist is a challenging and exciting topic that questions everything students think they know about art. In Year 9, students investigate how contemporary art uses irony, appropriation, and everyday objects to critique society. This topic aligns with ACARA's focus on analyzing how contemporary art challenges traditional concepts of authorship and 'high art'.

Students explore the idea that the 'meaning' of a work is created by the viewer as much as the artist. They look at how artists like Marcel Duchamp or Andy Warhol used existing images and objects to create new narratives. This topic thrives on structured debates and collaborative investigations, where students must argue for or against the 'artistic value' of a work, forcing them to define their own aesthetic values in a post-modern world.

Active Learning Ideas

Watch Out for These Misconceptions

Common MisconceptionPost-modern art is just 'lazy' because they use other people's work.

What to Teach Instead

Appropriation is a deliberate tool used to comment on culture and ownership. Active 'remix' challenges help students see that choosing and re-contextualising an image is a complex creative act.

Common MisconceptionThere is only one 'correct' meaning to a painting.

What to Teach Instead

Post-modernism teaches that meaning is subjective. Peer-to-peer 'interpretation' sessions where students share wildly different views on the same work help reinforce this concept.

Frequently Asked Questions

What does 'The Death of the Artist' mean?
It is a concept by Roland Barthes suggesting that the artist's intention doesn't matter as much as the viewer's interpretation. Once the work is 'out there', the audience 'owns' the meaning.
How can active learning help students understand post-modernism?
By engaging in 'remix' and 'appropriation' activities, students move from being confused by post-modernism to using it as a tool. They begin to see that art can be a conversation with the world around them, not just a 'pretty picture'.
What is 'Appropriation' in art?
It is the intentional borrowing, copying, and alteration of existing images and objects. It is a key technique in post-modern art used to challenge ideas of originality.
How does this link to ACARA standards?
It covers AC9AVA10R01 (analysing how contemporary art questions traditions) and AC9AVA10C01 (evaluating the role of the artist and the audience).
