The measures are based on desired student outcomes such as math and reading scores, but they have a number of potential drawbacks. One of them is the inconsistency in estimates for the same teacher when value added is measured in a different year, or for different subjects, or for different groups of students. Some of the differences in value added from year to year result from true differences in a teacher’s performance. Differences can also arise from classroom peer effects; the students themselves contribute to the quality of classroom life, and this contribution changes from year to… Continue Reading →

eric.ed.gov har udgivet: This research brief presents selected findings from work examining the stability of value-added model estimates of teacher effectiveness and their implication for tenure policies. Findings show year-to-year correlations in teacher effects are modest, but pre-tenure estimates of teacher job performance do predict estimated post-tenure performance in both math and reading, and would therefore seem to be a reasonable metric to use as a factor in making substantive teacher selection decisions.

eric.ed.gov har udgivet: On August 14, 2010, the “Los Angeles Times” published the results of a statistical analysis of student test data to provide information about elementary schools and teachers in the Los Angeles Unified School District (LAUSD). The analysis, covering the period from 2003 to 2009, was put forward as an evaluation of the effects of schools and their teachers on the performance of students taking the reading and math portions of the California Standardized Test. In Los Angeles, teachers were classified into one of five levels of “effectiveness” for their teaching in reading, math and a composite of the two. The decision by the “L.A. Times” to make these results publicly available at a dedicated web site, and to publish an extensive front page story that contrasted–by name–teachers… Continue Reading →

eric.ed.gov har udgivet: Teachers play a critical role in establishing classroom and school environments that contribute to students’ social and emotional development. This paper explores whether we can estimate a classroom-level measure of student growth in SEL by applying value-added models to students’ [social-emotional learning] SEL. We analyze data from the 2016 and 2017 administrations of student self-report surveys, which contain responses from roughly 40,000 students in Grade 5 within five of California’s CORE Districts. We estimate separate value-added models for each of the four SEL constructs assessed–growth mindset, self-efficacy, self-management, and social awareness–and for math and [English language arts] ELA academic growth. We find across-classroom-within-school variance of students’ SEL outcomes, even after accounting for school-level variance. The magnitude of classroom-level impacts on students’ growth in SEL appears similar to… Continue Reading →

eric.ed.gov har udgivet: This study examines the effects of including the summer period on value-added assessments (VAA) of teacher and school performance at the early grades. The results indicate that 40-62% of the variance in VAA estimates originates from the summer period, depending on the outcome (i.e., reading or math achievement gains). Furthermore, when summer is omitted from the VAA model, 51-61% of the teachers and 58-61% of the schools change performance quintiles, with many changing 2-3 quintiles. Extensive statistical controls for student background and classroom and school context reduce the summer effect, but 36-47% of the teachers and 42-49% of the schools are still in different quintiles. Furthermore, besides misclassifying teachers and schools, the results show that including summer tends to bias VAA estimates against schools with concentrated poverty.… Continue Reading →

eric.ed.gov har udgivet: To understand the immediate impact of a university-school district partnership that places preservice teachers (both traditional undergraduates and graduate students in an initial licensure residency program) in a Professional Development School (PDS) model, this exploratory study reviewed data from yearly examinations required by the Kansas State Department of Education for the purpose of monitoring average yearly progress in reading and math. Scores of students (grades 3-5) in 16 PDS sites were compared to scores of students in 16 non-PDS sites in the same district, matched for similarity based on demographic criteria. Findings indicate statistically significant differences in gains in the percent of students performing at or above proficient on state reading assessments, with students attending PDS sites outperforming those who attend non-PDS sites. Findings related to math… Continue Reading →

eric.ed.gov har udgivet: It is widely believed that the teacher is one of the most important factors influencing a student’s success at school. In many countries, teachers’ salaries and promotion prospects are determined by their students’ performance. Value-added models (VAMs) are increasingly used to measure teacher effectiveness to reward or penalize teachers. The aim of this paper is to examine the relationship between teacher effectiveness and student academic performance, controlling for other contextual factors, such as student and school characteristics. The data are based on 7543 Grade 8 students matched with 230 teachers from one province in Turkey. To test how much progress in student academic achievement can be attributed to a teacher, a series of regression analyses were run including contextual predictors at the student, school and teacher/classroom level.… Continue Reading →

ABSTRACT Value-added models (VAMs) of student test scores are used within education because they are supposed to measure school and teacher effectiveness well. Much research has compared VAM estimates for different models, with different measures (e.g., observation ratings), and in experimental designs. VAMs are considered here from the perspective of graphical models and situations are identified that are problematic for VAMs. If the previous test scores are influenced by variables that also influence the true effectiveness of the school/teacher… Continue Reading →

Uncheck the box to turn MathJax off. This feature requires Javascript. Click on a formula to zoom. ABSTRACT As states and districts incorporate value-added estimates into multiple-measures systems of teacher evaluation, it has become increasingly important to understand how to model value added when the same student is taught the same subject by multiple teachers. Roster data on teacher–student links that have been checked and confirmed by the teachers themselves show levels of co-teaching far beyond what appear in administrative data. Therefore, to help states and districts overcome a potential limitation in the use of value… Continue Reading →

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: ABSTRACT ABSTRACT Some educators are concerned that students with test scores at top of the test score distribution will negatively affect the value-added estimates of teachers of those students. A conventional wisdom has sprung up suggesting that students with very high test scores have “no room to grow,” so value-added estimates for teachers with high-performing students will be depressed even for highly effective teachers. Using empirical data, we show that under normal circumstances, in which few students score at the ceiling, a teacher of high-performing students—even with many students scoring at the ceiling on the pre-test—can have a high value-added estimate. To understand how more extreme ceiling effects can change value-added estimates, we simulate a low ceiling, causing student test… Continue Reading →
