Implementing the Oregon Framework for Teacherand Administrator Professional EvaluationPresenter - John Cronin, Ph.D.Contacting us:Rebecca Moore: 503-548-5129E-mail: rebecca.moore@nwea.orgThis PowerPoint presentation and recommended resources areavailable at our SlideShare website:http://www.slideshare.net/NWEA/tag/kingsbury-centerThis presentation is the top presentation on this page 3. Suggested readingBaker B., Oluwole, J., Green, P. (2013). The legalconsequences of mandating high stakesdecisions based on low quality information:Teacher evaluation in the Race to the Top Era.Education Policy Analysis Archives. Vol 21. No5. 4. We have entered an area of the law with littleguiding precedent. In such cases remember. Its rarely good to be the first wildebeest into the Zambezi River. 5. The difference between formative and summative evaluation Formative evaluation is intended to give educatorsuseful feedback to help them improve their jobperformance. For most educators formativeevaluation should be the focus of the process. Summative evaluation is a judgment of educatorperformance that informs future decisions aboutemployment including granting of tenure,performance pay, protection from layoff. 6. Teacher evaluation requirement Tested subjects (Math and ELA) State assessment One additional measure Non-tested subjects two of (all other) Common measure (national, regional, or district developed) Mandatory Classroom-based measure School-wide measure 7. Administrator evaluation requirement Two goals One must be the state assessment The other must come from: A common measurement Other measures such as graduation rate, attendance rate, discipline data, collegereadiness indicators Aligned with achievement compact indicators when possible 8. Unique features of Oregons approach Peer review panels for evaluation and supportsystems Local control Student growth data isnt a fixed percentage of the evaluation Districts decide how to translate performance to ratings. 9. Distinguishing teacher effectiveness from teacher evaluation Teacher effectiveness The judgment of a teachersability to positively impact learning in the classroom. Teacher evaluation The judgment of a teachersoverall performance including: Teacher effectiveness Common standards of job performance Participation in the school community Adherence to professional standards 10. Distinguishing teacher effectivenessfrom teacher evaluation Testing A claim that the improvement in learning (or lack ofit) reflected on one or more tests is caused by the teacher. Classroom observation That the observers ratings orconclusions are reliable and associated with behaviors thatcause improved learning in the classroom. 11. Purposes of summative evaluation An accurate and defensible judgment of aneducators job performance. Ratings of performance that providemeaningful differentiation across educators. 12. Differences between principal and teacher evaluationTeachers New groups of students each year Instruction of that group is limited to oneschool year.Thus teachers are normally held accountablefor yearly growth 13. Differences between principal and teacher evaluationPrincipals Inherit a pre-existing staff. Have limited control over staffing conditions Work with this intact group from year to year.Thus principals should be evaluated on theirability to improve growth or maintain high levelsof growth over time rather than their studentsgrowth within a school year. 14. The testing to teacher evaluation process 15. Issues in the use of growth measuresMeasurement design of theinstrumentMany assessments are notdesigned to measure growth.Others do not measure growthequally well for all students. 16. Tests are not equally accurate for allstudentsCalifornia STAR NWEA MAP 17. Issues in the use of growth measures Instructional alignment Tests used for teacher evaluation should align to the teachers instructional responsibilities. 18. Common problems with instructional alignment Using school level math and reading results in theevaluation of music, art, and other specials teachers. Using general tests of a discipline (reading, math,science) as a major component of the evaluationhigh school teachers delivering specialized courses. 19.

A better approach When possible use a spring fall spring approach. Measure summer loss and incentivize schools andteachers to minimize it. Measure teacher performance fall to spring, giving asmuch instructional time as possible betweenassessments. Monitor testing conditions to minimize gaming of fallspring results. 22. Issues in the use of growth and value-added measures Instability of results A variety of factors can cause value- added results to lack stability. Results are more likely to be stable at the extremes. The use of multiple-years of data is highly recommended. 23. Issues in the use of growth and value-added measures Among those who ranked in the top category on the TAKS reading test, more than 17% ranked among the lowest two categories on the Stanford. Similarly more than 15% of the lowest value-added teachers on the TAKS were in the highest two categories on the Stanford.Corcoran, S., Jennings, J., & Beveridge, A., Teacher Effectiveness on High and Low StakesTests, Paper presented at the Institute for Research on Poverty summer workshop, Madison, WI(2010). 24.

Issues in the use of value-added measuresControl for statistical errorAll models attempt to address thisissue. Nevertheless, many teachersvalue-added scores will fall withinthe range of statistical error. 33. Test Question:There are 300 students in the 10th grade. Mary andMark want to find the students favorite color. Maryasks 30 people. Mark asks 150 people. Mark says:My conclusions are more likely to be right thanMarys.Why does Mark think he is right?Because he is a man. 34. Range of teacher value-addedestimates 35.

Value-added metrics are not useful in small ormedium district settings. Value-added metrics dont measure improvement inthe teacher population over time. Changes in the value-added model have the greatesteffect on extreme cases. 37.
