1
Estimated Oral Reading Fluency A New Measure in STAR-EL and STAR Reading

2
Its all about correlations! The link/correlation between fluency and reading comprehension is well documented. Measures of fluency were first used as a proxy for measuring comprehension. Reading First and DIBELS have placed great emphasis on fluency.

3
STAR and Est. ORF Resulted from a correlational study looking at –STAR (EL and Reading) scores –and DIBELS Oral Reading Fluency Statistically HUGE sample –N=12,220

4
Wow! What a correlation!

6
Things to point out G4 – R=0.71 G3 – R=0.78 G2 – R=0.84 G1- R=0.87

7
Interpreting a Correlation Can be positive or negative 0.0 = no correlation 1.0 = complete, 1-to-1 correlation Correlations are deemed statistically significant at about 0.3, depending on the sample size (N) To turn a correlation into a more easily understood framework, square it. The result then represents, roughly, the percentage of the time that you could correctly accurately predict one measure with the other.

9
A Powerful Correlation! 0.87 x 0.87 = 0.756 –With one measure (STAR scale score or DORF) you could correctly accurately predict the other measure 75.6% of the time. Remember this formula, I C
