Abstract

One of the issues in value-added assessment of teachers is the persistence of effects. Although Generalized Persistence (GP) model addresses this issue, it is not commonly used because of the difficulty interpreting its results. The purpose of this study is to examine teachers’ value-added scores using the GP model and interpret the findings in terms of teacher assessment. Test scores of the same students (1432 students studying in 12 different middle schools) for three consecutive test administrations were used to estimate value-added scores of 61 science and 42 Turkish teachers. While correlation between current and future year value-added scores was high for science teachers (r = 0.88), it was lower for Turkish teachers (r = 0.46). On the other hand, the reliability of the estimates was found to be low. The study is concluded with suggestions for the use of the GP model and implications for further research and policy use.

利用广义持续模型估算教师的增值效应

教师增值评估的问题之一是效果的持续性。尽管广义持续性模型（GP）解决了这一问题，但由于其结果难以解释，因此并不常用。本研究的目的是利用 GP 模型研究教师的增值得分，并从教师评价的角度解释研究结果。研究使用了同一学生（在 12 所不同中学就读的 1432 名学生）连续三次的考试成绩来估算 61 名理科教师和 42 名土耳其教师的增值分数。理科教师当年和未来一年的增值分数之间的相关性较高（r = 0.88），而土耳其语教师的相关性较低（r = 0.46）。另一方面，估计值的可靠性较低。研究最后提出了使用 GP 模型的建议以及进一步研究和政策使用的意义。
