1. Why Do We Supervise Instruction? To assess teacher performance To improve professional practice

2. Why do we want to Improve Professional Practice? To raise student achievement

3. Why do we want to raise student achievement? Individuals –Increased lifetime salary –Improved health –If you don’t have a Bachelor’s degree, you are worse off than in 1975 if you do you are better off

4. Why do we want to raise student achievement? Society –Lower criminal justice costs –Lower health care costs –Increased economic growth

5. What’s the solution? Is it Structural? –Small schools –K-8 schools –Class size (about a 4% increase in achievement for a 50% cut in class size) –Class grouping

6. What’s the solution? Is it Alignment? –Curriculum reform –Textbook replacement Is it governance? –Charter schools –Vouchers Is it Technology?

7. IT’S THE TEACHER

8. Effect of Teacher Effectiveness on Student Achievement 3 rd graders placed with 3 high performing teachers in a row averaged 96 th percentile at end of 5 th grade in math 3 rd graders placed with 3 low performing teachers in a row averaged 44 th percentile at end of 5 th grade in math Tennessee’s State Math Test

9. “The results of this study well document that the most important factor affecting student learning is the teacher…more can be done to improve education by improving the effectiveness of teachers than by any other single factor. Effective teachers appear to be effective with students of all achievement levels, regardless of the level of heterogeneity in the classroom.” William Sanders

10. The effects on achievement of both strong and weak teachers persisted over 3 years

11. Dallas Study 1st graders placed with 3 high performing teachers in a row increased from 63 rd percentile to 87 th on ITBS math 1st graders placed with 3 low performing teachers in a row decreased from 58th percentile to 40 th on ITBS math The difference in reading was 42 points

12. Dallas Study The negative effect of poor- performing teachers persisted through three years of high- performing teachers - it took 3 yrs. For the kids to catch up. Lower achieving students are more likely to be put with less effective teachers

13. “Highly Effective teachers are able to produce much greater gains than their less effective counterparts.” “…not only does teacher quality matter when it comes to how much students learn, but also that, for better or worse, a teacher’s effectiveness stays with students for years to come.” Tucker & Stronge In Linking Teacher Evaluation and Student Learning

14. How do we get better teachers? Replace existing teachers with better ones –Increase pay No evidence that increased pay brings better teachers –Change certification standards No evidence that there are better teachers out there deterred by certification requirements “Love the one your with” (CSN&Y) Improve the effectiveness of existing teachers
