The Stability Problem of Value-added Models in Teacher Effectiveness Estimations: A Systematic Review Study

Aslantas, Ismail; Axbey, Harriet; Riddle, Sharon

Abstract

This article provides evidence by undertaking a systematic review on the stability problem of using value-added models in teacher effectiveness estimates from the perspective of the impact of the number of previous test scores employed aimed at answering a unique review question (This is a long sentence that lacks clarity – it could be broken down for a clearer meaning): How stable is teacher effectiveness estimates measured by VAMs? By using the terms: teacher performance, student performance, value-added model, stability and their other related synonyms, a comprehensive search was conducted in 17 databases along with employing hand search in Google Scholar and contacting authorised persons by email. In total 1439 records were found as a result of the searches. After completing the screening process, 50 studies remained for data extraction. Out of 50 a total of studies in the review list, 13 focused on the stability of VAM estimates regarding using the number of prior test scores. In summary, there is a common view that the use of prior year data in on value-added estimates for teacher effectiveness has a positive impact, however, with regard to the impact of multiple previous year data, different voices arose from the researchers.
