Making MAP More MeaningfulWinter 2008 David Dreher, Project Coordinator Office of Accountability Highline Public Schools
Overview • Recap of Predicting 2008 WASL • Examining 2008 WASL Predictions • Moving Forward to 2009
RECAP WERA Spring 08 Presentation • Predictions Released November 2007 • A “best guess” about each student’s performance on the upcoming WASL based on prior MAP and/or WASL performance • Intended Uses • Provide building staff with a level of risk for not meeting WASL standard. • School- and District- level 2008 WASL “forecasts” • Theory: Putting MAP scores in context with WASL scores will make MAP more meaningful.
Example of Projection and Prediction7th Grade Student in Reading
WASL Prediction Range • Constructed using the SEM values reported in the 2001 WASL Technical Reports. • Predicted Range = Predicted WASL Score +/- SEM
Interpreting Predictions • If the prediction range is: • Entirely below 400 (ex.: 380-396): student has less than a 20% chance on the WASL this spring unless we accelerate their learning. • Straddles 400 (ex.: 396-410): student has basically a coin-flip chance on the WASL, even if their prediction is above 400. • Entirely above 400 (ex.: 408-424): student has more than an 80% chance on the WASL in the spring, IF they continue to progress.
Spring 2008: WASL happened . . .Late Summer 2009: WASL results arrive!
Examining the Predictions • Reliability Analysis • Repeated the “Backward Look” analysis • “Within Group Look” • Analysis of “Exceptional” Performances • Predicted Level Analysis
“Backward Look”: Math % = Actual Met / Predicted to Meet Predicted to Meet = Predicted WASL score of 400 or better.
“Backward Look”: Reading % = Actual Met / Predicted to Meet Predicted to Meet = Predicted WASL score of 400 or better.
“Within Group”: Math % = Actual Met Within Group / Total Number In Group
“Within Group”: Reading % = Actual Met Within Group / Total Number In Group
Questions/Comments • Procedures for making predictions • Results of reliability analyses • What about our theory behind doing this? • “Putting MAP scores in context with WASL scores will make MAP more meaningful.”
“Meaningful”: Depends on Who You Ask • My experience talking with the people who work directly with the kids suggests that the strength of our ability to assess the risk level of their students doesn’t impress them. • “You don’t need a weatherman to tell you which way the wind blows” Bob Dylan
Data Creators Office Of Accountability Data Users Principals, Coaches, Teachers What would be more “Meaningful”? • Information that would help determine whether things done to help kids pass the WASL worked
But . . .I don’t really know what schools are doing to try to help kids pass the WASL. . . So . . .how can I find out?
“Exceptional” Performance Analysis • Please see handout • Objective: Start conversations that would increase the flow of information from data users back to us in Accountability • What are your observations of the data?
Expectations for “Above Level” • Students were receiving interventions designed to address skills/knowledge deficits • Students were receiving interventions designed to familiarize them with WASL format • Students benefited from actions taken by the school to improve the WASL testing environment • Your ideas?
Expectations for “Below Level” • Students were ELL or SPED • Students were chronically absent or highly mobile • Students did not take the WASL seriously • Your ideas?
Moving Forward • Predictions simplified: Use BSI designations only • Raising awareness and understanding of NWEA’s Alignment Study • Increase understanding of NWEA goals and how to interpret goal-level results • Investigate the possible use of MAP data in evaluation of interventions, initiatives, and programs

What is MAP • Measures of Academic Progress • Developed by the Northwest Evaluation Association • Norm-referenced assessment • Computerized and adaptive • Performance is reported as a RIT score • The RIT Scale • Uses individual item difficulty values to estimate student achievement • A RIT score has the same meaning regardless of grade level • Equal interval scale • Highline Public Schools • Three testing windows per year (Fall, Winter, Spring) • Test students in the areas of math and reading • Test students in grades 3-10
The Needs of the Data User • Building staff were saying things like . . . • “How can we use MAP data to help us make decisions?” • “How do MAP and WASL performance compare?” • “I want to know what a student’s history is with MAP.” • “What is a RIT score?” • “Giving me a RIT score is like telling me the temperature in Celsius!”
Making The Predictions • Snooped and found the best indicators of WASL success • Applied linear regression models to generate WASL scores for each student • Examined the predicted WASL scores
Projecting MAP to Spring • For the models with “Projected MAP” as one of the factors individual student performance on MAP in the Spring of 2008 was projected. • The amount of expected growth added to a student’s Highest MAP score came from NWEA’s Growth Study
What we learned by snooping. . . • Correlations were generally good. • Reading R-value range: 0.711 - 0.835 • Math R-value range: 0.603 - 0.921 • Correlations in math were stronger than in reading. • “Highest MAP” consistently correlated better than any single MAP score. • Correlations were generally strongest when Highest MAP and WASL 2006 factors were combined.
Regression Models For students with both MAP and 2006 WASL scores (~95%) WASL 2007 = b0 + b1*Highest MAP + b2*WASL 2006 For students that only had MAP score(s) (~3%) WASL 2007 = b0 + b1*Highest MAP For students that only had WASL 2006 score (~2%) WASL 2007 = b0 + b1*WASL 2006 Where: Highest MAP = The student’s highest score on MAP from the Fall 2006, Winter 2007, or Spring 2007 windows. Typically Spring 2007. WASL 2006 = The student’s raw score from the 2006 WASL Spring testing.
Prediction Models For students with both MAP and 2007 WASL scores WASL 2008 = b0 + b1*Projected MAP + b2*WASL 2007 For students with only MAP score(s) WASL 2008 = b0 + b1*Projected MAP For students with only WASL 2007 score WASL 2008 = b0 + b1* WASL 2007 Where: Projected MAP = Projected Spring 2008 MAP score based on the student’s highest score on MAP from the Winter 2007, Spring 2007 or Fall 2008 windows. WASL 2007 = The student’s raw score from the 2007 WASL Spring testing.
