eric.ed.gov har udgivet: We investigate the relationship between teacher licensure test scores and student test achievement and high school course-taking. We focus on three subject/grade combinations–middle school math, ninth-grade algebra and geometry, and ninth-grade biology–and find evidence that a teacher’s basic skills test scores are modestly predictive of student achievement in middle and high school math and highly predictive of student achievement in high school biology. A teacher’s subject-specific licensure test scores are a consistent and statistically significant predictor of student achievement only in high school biology. Finally, we find little evidence that students assigned to middle school teachers with higher basic-skills test scores are more likely to take advanced math and science courses in high school.

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 →

ABSTRACT To illustrate and document the tenuous connection between the Wilcoxon–Mann–Whitney (WMW) procedure and medians, its relationship to mean ranks is first contrasted with the relationship of a t-test to means. The quantity actually tested: Pr ^(X1<X2)+ Pr ^(X1=X2)/2 is then described and recommended as the basis for an alternative summary statistic that can be employed instead of medians. In order to graphically represent an estimate of the quantity: Pr(X1 < X2) + Pr(X1 = X2)/2, use of a… Continue Reading →

eric.ed.gov har udgivet: We use panel data in Washington State to study the extent to which teacher assignments between fourth and eighth grade explain gaps between advantaged and disadvantaged students–as defined by underrepresented minority status (URM) and eligibility for free or reduced price lunch (FRL)–in their eighth grade math test scores and high school course taking. We find some significant gaps between advantaged and disadvantaged students in the value added of the teachers to which they are assigned in these grades, although gaps in middle school grades are sensitive to the specification of value added. We then show that teacher assignments are highly predictive of both eighth-grade test scores and advanced course taking in high school, and that differences between advantaged and disadvantaged students in teacher assignments explain significant portions… Continue Reading →

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: Abstract Abstract Informally testing the fit of a probability distribution model is educationally a desirable precursor to formal methods for senior secondary school students. Limited research on how to teach such an informal approach, lack of statistically sound criteria to enable drawing of conclusions, as well as New Zealand assessment requirements led to this study. Focusing on the Poisson distribution, the criteria used by ten Grade 12 teachers for informally testing the fit of a probability distribution model was investigated using an online task-based interview procedure. It was found that criteria currently used by the teachers were unreliable as they could not correctly assess model fit, in particular, sample size was not taken into account. The teachers then used an… Continue Reading →
