The problem of local item dependencies (LIDs) is very common in personality and attitude measures, particularly in those that measure narrow-bandwidth dimensions. At the structural level, these dependencies can be modeled by using extended factor analytic (FA) solutions that include correlated residuals. However, the effects that LIDs have on the…

Average score change: How big is big? This paper discusses school-level changes in average ACT scores and highlights an interactive tool designed to facilitate score change comparisons.

When cognitive and educational tests are administered under time limits, tests may become speeded and this may affect the reliability and validity of the resulting test scores. Prior research has shown that time limits may create or enlarge gender gaps in cognitive and academic testing. On average, women complete fewer items than men when a test…

In evolution education, misconceptions about evolutionary concepts impact students' learning. Much research exists on assessing knowledge about evolution using different instruments. The current article introduces the KAEVO 2.0 instrument, which includes various evolutionary aspects representing microevolution and macroevolution. The introduced…

Science, technology, engineering, and mathematics (STEM) influence almost every aspect of our daily lives. However, despite the high demand for STEM occupational talent, the STEM pipeline continues leaking, with less than one-sixth of high school students pursuing STEM majors and only 50% of entering STEM majors matriculating into STEM fields.…

This research aims to reveal the effectiveness of the use of Kofie GeBoL media in improving (1) vector representation ability and (2) critical thinking ability in physics instruction. It is a descriptive quantitative study with the quasi-experiment design. It was conducted in two stages: empirical try out and implementation of Kofie GeboL to see…

In several sporting events, the winner is chosen on the basis of a subjective score. These sports include gymnastics, ice skating, and diving. Unlike for other subjectively judged sports, diving competitions consist of multiple rounds in quick succession on the same apparatus. These multiple rounds lead to an extra layer of complexity in the data,…

The objective of this instrumental study (Ato, López & Benavente, 2013) or psychometric-type (Alarcón, 2008) was to estimate the validity and reliability of the Self-Efficacy Inventory for Multiple Intelligences-Revised (IAMI-R, Pérez & Cupani, 2008) in Peruvian students of fifth year of high school. We worked with a sample of 1304…

Introduction: Students' perceptions of the assessment tasks can be a basis for optimizing the classroom assessment environment. In an attempt to quantify students' perceptions of assessment, Dorman and Knightley (2006) developed Perceptions of Assessment Tasks Inventory (PATI). This study sought to provide evidence for the construct validity of…

The prevalence of bullying has increased over the past decade and is a public health concern. Existing measures of bullying lack breadth and/or psychometric support, which may inaccurately represent current rates of bullying. The purpose of this study was to develop and validate a psychometrically sound measure, the Multidimensional Bullying…

This paper is based on the background of the problem of the low high order thinking skills in students, especially in the skills to think creatively and conceptual understanding. Conceptual understanding that students have in relation to physics learning material has an important role in developing students' high order thinking skills in solving…

For several decades, researchers have explored the efficacy of functional behavior assessments. Recent research has called for greater understanding of how student involvement may improve the functional behavior assessment. This may be particularly important in high school settings, because high school environments are often larger and more…

The Every Student Succeeds Act requires states to identify schools with low-performing student subgroups for Targeted Support and Improvement or Additional Targeted Support and Improvement. Random differences between students' true abilities and their test scores, also called measurement error, reduce the statistical reliability of the performance…

This Snapshot highlights key findings from a study that used Bayesian stabilization to improve the reliability (long-term stability) of subgroup proficiency measures that the Pennsylvania Department of Education (PDE) uses to identify schools for Targeted Support and Improvement (TSI) or Additional Targeted Support and Improvement (ATSI). The…

The "Stabilizing Subgroup Proficiency Results to Improve the Identification of Low-Performing Schools" study used Bayesian stabilization to improve the reliability (long-term stability) of subgroup proficiency measures that the Pennsylvania Department of Education (PDE) uses to identify schools for Targeted Support and Improvement (TSI)…
