The US Department of Education has put out the draft priorities for the next round of the Teacher Incentive Fund and invited public feedback. The Teacher Incentive Fund provides grant dollars to school districts and partners that want to explore ways to recognize and reward effective teaching. More about TIF and the proposed priorities can be found here.

We have learned quite a bit from being part of a Teacher Incentive Fund grant along with six Oregon school districts. You can read our full feedback letter to the USDOE here. Here are the highlights:

Evaluations: Require a minimum of four, not three, categories for teaching proficiency

In the proposed selection criteria, the Department requires a Rigorous, Valid, and Reliable Educator Evaluation System that includes at least three performance levels.  However, advice from respected national leaders, including Charlotte Danielson, indicates that a three-level proficiency system leads to “central tendency,” or the notion that most professionals will end up in the middle category because it is safer to mark and easier to defend. This provides less differentiation for informed practice and limits the distinctions needed for improvement.  Additionally, we note that every respected national model has a minimum of four levels.  We are not aware of any respected, research-based rubrics for teaching proficiency based upon a three level framework.

With the controversy surrounding value-added models, including the recent release of teacher rankings in New York, it could be easy to give up on the models altogether as too controversial, unreliable or volatile.

In fact, these descriptors can be true. There is value to be found in value-added, however, if the models are used in an appropriate context.

Much of the controversy is related to how value-added models are being used, not the models themselves. VAM is a statistical analysis of test score growth. It makes predictions about student test score growth based on previous test scores and demographics and then compares those predictions to actual growth.

VAM is a new way to look at test score growth. The models themselves are not education “reform,” just as calculating graduation rates or dropout rates does not automatically lead to any particular use of that information.

This afternoon we held the second webinar in our virtual brown bag series on value-added measures. The recorded presentation (audio + powerpoint) can be viewed or downloaded here.

The presentation and discussion include an explanation of what VAM is, how it is different than other measures of school performance, and a bit of national and local context around how it is being used in education. The webinar features talks from Kevin Booker from Mathetmatica Research, Andrew Dyke from ECONorthwest, and Kathleen Sundell from the Salem Keizer Education Association. Feel free to post questions for the experts in the comments section.

In the future, what topic would you like to learn more about?

Looking to keep you informed and keep your questions answered, we want to know what you think our next webinar topic should be. Post your ideas in the comments section or email them to info@chalkboardproject.org, and stay tuned for information about our next virtual brown bag webinar!

 

WHAT IS A ‘VALUE-ADDED MODEL’ AND HOW IS ‘VAM’ BEING USED IN OREGON?

We are continuing our webinar series with a conversation about value-added models–a complex statistical tool for measuring student growth. The discussion will include an explanation of what VAM is, how it is different than other measures of school performance, and a bit of national and local context around how it is being used in education.

Each of these virtual brown bags are designed to provide you with relevant news about education issues and to hear first-hand accounts of ongoing developments from local, state and national policy experts and educators.

JOIN US FOR THIS CONVERSATION.
