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

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

  4. Wow! What a correlation!

  5. 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. 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. Interpreting a Correlation

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

  9. 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 A Powerful Correlation!
