Transcript of Value Added

  • 1. Value-added by Dr. William Sanders Lets really leave no child behind.
  • 2. What have we really been doing with data? Historically, we have been shelving it into a filing cabinet.
  • 3. What are the problems with how we look at data now? We see how the middle level students of our classes perform but does our current system really measure our highest and lowest performers?
  • 4. Introducing the value-added method It works much like a pediatricians scale. It measures growth from year to year.
  • 5. Purposes of measurement: Measure each child One days testing could be influenced by a variety of factors Look at comparable plots on many children can lead us to inferences about certain classrooms Each student serves as his/her own control
  • 6. The goal of value-added Increase the academic achievement for every child
  • 7. Sample What inferences can we make scores from this data? 800 600 400 200 2 3 4 5 District Student Student grade
  • 8. This is not enough data to accurately show information about the teacher of first or second grade. What if we saw the progress of all the students in that teachers class and then for various years?
  • 9. Types of Patterns Shed patterns some of the most hurtful that exist in schools. This happens when the Shed pattern Gain lowest achievers make the greatest gains and the highest achievers are held back. Previous Achievement
  • 10. Tee-Pee patterns this occurs when teachers focus their instruction Tee-Pee pattern on the average students in the class. Average Gain students make the greatest gain and those at the top and bottom of the class have less gain. Previous achievement
  • 11. June Rivers Study Examined the performance of eighth grade students on ninth grade proficiency tests and linked these scores back to performance on fourth grade tests to predict the possibility of passing on the first attempt a ninth grade test.
  • 12. Findings: Students assigned a Students assigned a sequence of teachers in sequence of teachers the top quintile for 4 from the bottom years had a 60% passing quintile had a 15% rate. passing rate.
  • 13. Realized Gain Grade 100% 80% 110% 110% 120% 60% level 2 2.0 2.0 2.0 1.0 1.0 1.0 3 3.0 2.8 3.1 2.1 2.2 1.8 4 4.0 3. 4.2 3.2 3.4 2.6 5 6.0 4.4 5.3 4.3 4.6 3.4 6 6.0 5.2 6.4 5.4 5.8 4.2 7 7.0 6.0 7.5 6.5 7.0 5.0 8 8.0 6.8 8.6 7.6 8.2 5.8
  • 14. Why is this important? Value-added research tells us that teacher effectiveness is the single largest factor affecting academic growth.
  • 15. Highly effective teachers Ensure that all children are achieving Teach students from where they are Differentiate instruction and focus on individuals Make excellent gains across the previous achievement spectrum
  • 16. Highly effective schools Link teachers over grade levels and focus on gains in achievement grade by grade.
