How do we measure learning in Cleveland? • Formative data sources: • Student work. • Short-cycle assessments which focus on a narrow range of skill. • Benchmark tests which have been aligned to the State high-stakes testing and measure a larger skill set.
How do we measure learning in Cleveland? • Formative data sources: • Student work. • Short-cycle assessments which focus on a narrow range of skill. • Benchmark tests which have been aligned to the State high-stakes testing and measure a larger skill set. • These are all used to actively shape instructional process: a feedback loop.
Using formative assessment to shape instruction: Standard Test to see if we are “On Course!”
Using formative assessment to shape instruction: Standard Use testing to “target” instructional practices to facilitate reaching learning goals.

What will “Value Added” analyses add to these? • A measure of change that is relative to the students’ prior levels of achievement.
What will “Value Added” analyses add to these? • A measure of change that is relative to the students’ prior levels of achievement. • Traditional criterion referenced summative assessment measures whether or not one has reached a threshold level of learning irrespective of one’s starting point.
What will “Value Added” analyses add to these? Finish Line = Criterion!
What will “Value Added” analyses add to these? Who has more learning “ground” to cover in order to cross the criterion finish line?
What will “Value Added” analyses add to these? • Value Added analyses take into account where different learners “start” by looking at past performance on accountability testing.
What will “Value Added” analyses add to these? • Value Added analyses take into account where different learners “start” by looking at past performance on accountability testing. • Past testing data is used in a complex statistical modeling method (mixed-model a.k.a. multilevel modeling or hierarchical linear modeling) to develop predicted scores for a student based on like scoring students.

What will “Value Added” analyses add to these? This student is still below proficient on the accountability measure. . .
What will “Value Added” analyses add to these? This student is still below proficient on the accountability measure. . . But, he has advanced beyond his predicted level of performance – this gain beyond his predicted score would be attributed to his teacher and/or school = Value Added.
What will “Value Added” analyses add to these? • As a measure of relative change, Value Added has the promise to offer a means to credit teachers whose children show gain beyond what would be expected given their past performance; however. . .

More Questions to be addressed when placing Value Added analyses in context: • All predicted scores have error. . . • Value added analyses take this into account when interpreting gains for students, teachers, and schools.
More Questions to be addressed when placing Value Added analyses in context: • All predicted scores have error. . . • Value added analyses take this into account when interpreting gains for students, teachers, and schools. • This is a two-edged sword. On one hand, it minimizes the effect of any extreme scores. On the other, it means that two teachers can move students, on average, the same “distance” and receive different value added “scores” due to the standard errors associated with the predicted scores of their classrooms.

On one hand, it minimizes the effect of any extreme scores. On the other, it means that two teachers can move students, on average, the same “distance” and receive different value added “scores” due to the standard errors associated with the predicted scores of their classrooms. • This area will likely require close contextualization of the data in terms of the absolute gains in the class.
Conclusions • As a measure of relative change, Value Added has been promoted to offer a means to measure the effect of individual teachers and schools on students’ rate of learning.
Conclusions • As a measure of relative change, Value Added has been promoted to offer a means to measure the effect of individual teachers and schools on students’ rate of learning. • It would be of particular value as a means of formative assessment; however, it has been legislated as part of Ohio’s accountability system and will be in effect as such in 2007-2008.
