By the end of this module, participants will have:
This particular chart, which we call the “Magic Quadrant”, measures effect size from one NAPLAN test to another and compares it to achievement (attainment). The legend explains what each quadrant represents.
Each blue dot on the chart below represents a student.
By using the calculation for Effect Size (ES) as a measure of progress (vertical axis) and plotting a student's NAPLAN score (horizontal axis) against it, and comparing that against National averages, this chart shows the relative progress of each student in one subject area.
Task:
a) When you look at this “magic quadrant”, which quadrant/s of students have actually been the most successful?
b) What is the difference here between success and growth?
c) What questions would you pose about the students in the pink quadrant? How might this differ for students in the blue quadrant?
Reflection: Share your thinking with your team.
The same formula has been applied to study effect size from one ACER test to another in this document.
The Reference to measuring effect size is as follows:
Average score (test 2) minus Average score (test 1) divided by the standard deviation (spread of scores)
(NB: An effect size of 0.4 in 12 months is regarded as average)
Task:
On viewing the sample data, is there a student who:
Reflection: Share your responses with your team, and discuss why it is important to track growth as well as achievement.
Group Task:
Document either in paragraph or list form your statement of intent to introduce or maintain a growth culture at your school.
(NB: For this activity - the following questions might be useful to guide your response, teachers could consider their class culture and leaders the whole school culture)
Adapted from Measuring student growth: A guide to informed decision making
Post your school growth culture 'statement of intent'. Consider how this learning impacted on your area of research/inquiry?
Teams post their work/learning on the project google+ community and then respond to someone from their own team and another team’s work using the Ladder of Feedback.
Leaders: Consider also how you will share this learning within your school community.
