About

VAMboozled! is a blog about the issues surrounding teacher evaluation, teacher accountability, and value-added models (VAMs) in America’s public schools. VAMboozled! is also about the related issues surrounding America’s educational reform and accountability initiatives, and the federal and state policies being advanced, incentivized, adopted, and implemented across the nation. While other education blogs might focus on more general education topics, this blog is focused only on these issues, as current and controversial as they continuously are. The goal is to make more comprehensible and more accessible research-based information about these issues, and to better reach and inform teachers, administrators, policymakers, parents, students, and members of the general public, all of whom are stakeholders and who might ultimately be involved.

  1. I am looking into what research has to say about the average growth for students with a disability in reading and math. Do you know of any good research that relates to this topic? If so, please email to me. Thank you, Kim Sims

    • There are no references of which I am aware that only examine/discuss the VAM-related issues pertaining to students with disabilities, but here are some that discuss these issues in the most depth (even though in more peripheral ways). You can find these references under the “Glossary” link: Baker et al., 2010; Corcoran, 2010; Hill, Kapitula, & Umlan, 2011.

  2. There is a positive correlation between students in poverty and disabilities.
    Therefore, teachers of students at-risk have the additional burden of teaching students with disabilities, which makes their evaluation of student learning even worse. Just another reason why VAM estimates are not valid.
