The consistent prevalence of computer science in our society and the urgent need for STEM professionals in the U.S. raised the need for computer science education at the K-8 level. Researchers have examined the challenges, possible approaches, and contents of teaching computer science. However, there has been limited research on teachers'…

The COVID-19 pandemic began in the late months of 2019, and by the spring of 2020, to limit transmission of the virus, schools across the globe closed and transitioned to emergency online teaching. While the move to online teaching and learning was inevitable, many learners, especially in rural and remote areas, found that online schooling had…

We use data from a large-scale experiment conducted in Indiana in 2009-2010 to examine the impact of two interim assessment programs (mCLASS and Acuity) across the mathematics and reading achievement distributions. Specifically, we focus on whether the use of interim assessments has a particularly strong effect on improving outcomes for low…

The "GeoLiteracy for English language learners" (ELLs) program is a curriculum that enhances reading and writing skills while teaching geography content for US students in kindergarten through eighth grades. The program includes 85 lesson plans that address all US national geography standards, a quarter of which address environmental…

A vertical scale, in principle, provides a common metric across tests with differing difficulties (e.g., spanning multiple grades) so that statements of "absolute" growth can be made. This paper compares 16 states' 2007-2008 effect size growth trends on vertically scaled reading and math assessments across grades 3 to 8. Two patterns…

Under the new federal No Child Left Behind law, state assessments must be aligned to grade-level standards/benchmarks, and every school in Indiana and other states will soon be judged based on its ability to raise the percentage of students achieving proficiency on these tests. This will no doubt lead to much greater scrutiny of states'…
