Tips on basic data displays
Tips on basic data displays
“Most data require only the ability to count and calculate percentages. Any conscientious teacher or team of teachers can do this.”
Schmoker 1999
Butcher paper on the wallsPeters’ describes this data as “back
of the envelope” calculationsWall Street may never see it – but
it’s the data on the shop room floor that really improves the bottom line
Simple Comparative Data Displays multiple
factors Displays highs and
lows

GOAL
Yes, We made it !
Simple Comparative Data Shows the trends Compares multiple
factors
Compares performance against some predetermined standard or indicator Compared to other
classes, other students, other schools, state averages etc.
Could be graphed using bar graphs, line graphs etc.
Used to show the variation in scores
Example: Class writing rubric scores
Also called a line graph or time chart
Used to monitor progress
Examples: Monitor missed
class time due to tardies
Purpose: To find the root causeAsk “Why” five times to find the root
cause.
Don’t forget….
Most of us love kids, not charts and graphs
And….our only goal is to improve the skills and knowledge of our students
But….is it wrong for society to ask us…
“How do you know if you have?”
“It’s about the kids stupid!” (James Carville reinterpretation)
Personalize the Data (School board ISTEP/PAWS data example)
Put a Human Face on the Data “Our test scores went up!”
Collective data that is compiled by the grade level, department or team
It could track the groups progress It could compare one grade level or
department to another It could compare individual
classrooms
We have not yet addressed a ROOT problem in trying to raise student achievement….
The psychological and emotional engagement of our students
Lee Jenkins:
“We have to get them to understand how their individual efforts contribute to overall classroom improvements.”
The intentional use of individual and classroom graphical displays of data can encourage psychological and emotional engagement
Is the central message easy to get?Can a lay person who walks by “get
it?”Can they get it in 30 seconds? Is the display colorful? Is it simple?Do they know how to “feel” as well
as what to “think?”
Classroom and school-wide examples
These tools are designed to be applied to any problem you are trying to solve or idea you are trying to communicate
They could be District School Grade level or department Classroom Individual
Simple is betterTry to only display one or two conceptsUse “call outs” for the main ideaDon’t use jargon or acronymsUse stories or examples when possibleLabels and titles should be simple with
large fontsThe x and y axis should be balanced
between true accuracy and yet you should be able to see the trend line or differences
“Numbers have the power to reveal slow but steady improvement, and combat the fatalism prevalent in schools.”
