One part of COVID-19's staggering impact on education has been to suspend or fundamentally alter ongoing education research projects. This article addresses how to analyze the simple but fundamental example of a multi-cohort study in which student assessment data for the final cohort are missing because schools were closed, learning was virtual,…

Introducing kindergarten children to the engineering design process (EDP) is an important objective of early STEM education. Studies indicate that children often miss the crucial steps of testing and optimising during the EDP and do not persist in making solutions better. The present study explores how children's goal awareness, self-evaluation…

This article deepens the knowledge of middle leaders' impact on school improvement and organisation development. More precisely, it focuses on how middle leaders from comprehensive schools and preschools translated improvement strategies and tools from a municipal course on leading school improvement into their own organisations. It is based on…

K-12 students are expected to acquire competence in data display as part of developing statistical literacy. To support research, assessment design, and instruction, we developed a hypothesized learning progression (LP) using existing empirical literature in the fields of mathematics and statistics education. The data display LP posits a…

Authentic, "messy data" contain variability that comes from many sources, such as natural variation in nature, chance occurrences during research, and human error. It is this messiness that both deters potential users of authentic data and gives data the power to create unique learning opportunities that reveal the nature of science…

With the passage of the 2015 Every Student Succeeds Act (ESSA), states were required to add a fifth indicator on "School Quality or Student Success" (SQSS) to their school accountability systems. An analysis of submitted ESSA state plans found that 13 states included measures of school climate as their SQSS indicator or incorporated…

The "Washington English Language Proficiency Assessment" (WELPA) is a No Child Left Behind (NCLB)-compliant instrument that is used in Grades K-12 as a formal and standardized method of measuring language proficiency. The test results provide important information for classifying English Language Learners (ELLs) and subsequently for…

There has been a significant increase in the use of secondary data sets. Many such data sets purport to be nationally representative. Secondary data sets include research commissioned by the National Center for Education Statistics, the Centers for Disease Control, and other public entities. Research increasingly utilizes these secondary data in…

Literacy data collected over the course of 2 academic years were used to estimate the rate at which full- and half-day kindergartners acquired literacy skills during kindergarten, 1st grade, and the intervening summer. Application of piecewise growth models to the time series data obtained on a sample of students from a large Southwestern school…
