MYP 2: Summative assessment Unit 1
For every euro …
Goal:
You want the government of a certain EU country (you choose) to spend
either more or less on something. (It will be your decision what that thing is.)
Role:
You work for the PR department of an NGO. You want the public to be aware
of your opinions about the government budget.
Audience:
You want to reach a broader public, that follows your NGO on social media.
Most of your audience does not have a background in mathematics or
statistics.
Situation:
You have a table with data on government spending by EU countries, but you
think not everybody will be able to understand this table by itself.
Product:
You have decided to make an infographic that shows how your country is
different from other EU countries.
Your infographic will contain, at least:
-
A graph that compares spending of multiple countries
A simplified ratio (for example, “For every euro we spend on X, we spend Y euros on
Z”)
Information about the same ratio in other EU countries, or (preferably) in the EU as a
whole.
A clear and powerful visualization of one or more of these ratios
An interpretation: what conclusion do you draw about your government’s budget
choices?
(on a separate page) An explanation (1-2 paragraphs is enough) of your source, and
of how you used the data to make the infographic.
You will be assessed on criteria C (communicating) and D (application in real-life contexts).
For details, see the next page.
