Reading motivation is multidimensional and a critical contributor to students' reading comprehension skill. Its multidimensionality is problematic, as there is currently no consensus on the dimensions underlying reading motivation, which are being tested through a variety of instruments that lack statistical validation. Our goal was to discuss the…

There is a need for developmentally appropriate Computational Thinking (CT) assessments that can be implemented in early childhood classrooms. We developed a new instrument called "TechCheck" for assessing CT skills in young children that does not require prior knowledge of computer programming. "TechCheck" is based on…

Assessing students' emerging literacy skills is crucial for identifying areas where a child may be falling behind and can lead directly to an increased chance of reading success. The Waterford Assessment of Core Skills (WACS), a computerized adaptive test of early literacy for students in prekindergarten through 2nd grade, addresses this need.…

This report provides a description of the development process, field testing, and psychometric properties of a student mathematics test designed to assess grades K, 1, and 2 student abilities. The test was administered to 4,535 participating grade K, 1, and 2 students in 66 schools located in 9 public school districts in Florida during spring…

This report provides a description of the development process, field testing, and psychometric properties of a student mathematics test designed to assess grades K, 1, and 2 student abilities. The test was administered to 4,486 participating grade K, 1, and 2 students in 67 schools located in 10 public school districts in Florida during fall 2015.…

Knowledge of mathematical equivalence, the principle that 2 sides of an equation represent the same value, is a foundational concept in algebra, and this knowledge develops throughout elementary and middle school. Using a construct-modeling approach, we developed an assessment of equivalence knowledge. Second through sixth graders (N = 175)…

This study investigated the psychometrics of the "Diagnostic Evaluation of Language Variation-Screening Test" (DELV-S) test using confirmatory factor analysis, item response theory, and differential item functioning (DIF). Responses from 1,764 students in kindergarten through second grade were used in the study, with results indicating…

This report examines the "Performance Indicators in Primary Schools" (PIPS) test as a reliable and cohesive instrument to assess early literacy and numeracy skills among Indigenous children. The process includes the examination of the reliability of the PIPS test using the Cronbach Alpha and the Split-half method with Pearson's r…
