Scales of measure highly correlated to specific curriculum
Sufficient stretch in the assessment instrument
Appropriate reliabilities of measurement
What is the Purpose of Value- Added Measurement?
Provide longitudinal growth data on each student.
Data is for the teacher, principal, and school to utilize and take appropriate action.
What is the Goal of Value-Added?
What’s the Difference compared to the Current Measurement? AYP Value-Added School progress is an all-or-nothing affair Better measure of school improvement Teachers and administrators are held accountable Focus on individual classrooms Raise achievement of students in the subset that satisfies requirements Raise achievement of all students Compare last year students with current students Tracks individual students over time
Each student is measured
Viewing comparable plots on many students can point to certain classrooms
Aggregating data across classrooms lends itself to viewing the whole picture
Each student serves as his/her own control which eliminates socioeconomic variables as the cause for learning rate differences
Parents can view a snapshot of their child’s academic growth rate
Disadvantages of the Value-Added Model
The Value-Added Model does not inform us what highly qualified teaching looks like or how to duplicate it.
The model can only rate as good as the quality of the tests administered.
A collaboration of measures should be utilized in determining teacher effectiveness rather than solely being dependent upon one model.
Teaching Patterns The shed pattern occurs when the lowest achievers make the greatest gains in the classroom and the highest achievers are held back.
Teaching Patterns Continued… The reverse shed pattern occurs when the teacher is teaching to the high achievers at the expense of other students.
Teaching Patterns Continued… The Tee-Pee pattern is when the teacher is teaching right down the middle.
Implications on Teachers
Forces teachers to teach to all individual students
Best practices are sought after and shared
Improve data decision making
Builds learning communities
Improve focus and impact of instruction
1 st 10-12 years : Teachers have growing
2 nd 10-12 years : Highest level of
3 rd 10-12 years : Effectiveness declines
Highly Effective Teachers
Ensure that all students are achieving
Teach students from where they are
Differentiate instruction and focus on individuals
Make excellent gains across the previous achievement spectrum
Highly Effective Schools
Link teachers over grade levels and focus on gains in achievement grade by grade
Our nation, which has prevailed in conflict after conflict over several centuries, now faces a stark and sudden choice: adapt or perish. I'm not referring to the war against terrorism but to a war of skills -- one that America is at a risk of losing to India, China, and other emerging economies. And we're not at risk of losing it on factory floors or lab benches. It's happening every day, all across the country, in our public schools. Unless we transform those schools and do it now . . . it will soon be too late.
