This three-paper dissertation systematically investigates the methodology issues related to using observational systems to observe, analyze, and interpret teachers' reformed teaching practices within the K-12 classroom context. Each paper contributes a distinct perspective to evaluate instructional practices accurately, consistently, and…

This study assessed the psychometric properties of the culturally inclusive instructional design (CIID) scale with 31 items on a 7-point Likert scale. The data were collected from the training (N = 55) and validating samples (N = 80) of K-20 educators. Data analysis employed exploratory factor analysis (EFA) and confirmatory factor analysis (CFA).…

Deep science understanding is reflected in students' ability to use content and skills when making sense of the world. Assessing deep understanding requires measuring complex constructs that combine elements of content and skills. To develop valid measures of complex constructs, we need to understand how their theoretical dimensionality, reflected…

The SSIS SEL Brief + Mental Health Scales (SSIS SELb+MHS) are multi-informant assessments developed in the United States to assess the social and emotional learning (SEL) competencies and emotional behavior concerns (EBCs) of school-age youth. Although there are translations of the SEL items of the SSIS SELb+MHS available in other languages, a…

The present study investigated evidence of the construct validity of scores from the Scales for Assessing Emotional Disturbance Rating Scale (SAED-3 RS), which is designed to help identify emotional disturbance (ED) as defined by U.S. law and regulations. The purpose of this research was to evaluate the degree to which SAED-3 RS scores differed…

Using expert reviews and item response theory (IRT), this study evaluated the language- and culture-related construct-irrelevant variance and reliability of the 2019 TIMSS sense of school belonging scale (SSBS) for grades 4 and 8. The five items of the SSBS, which were identical for both grades, were reviewed for the language- and culture-related…

Large scale international assessments depend on invariance of measurement across countries. An important consideration when observing cross-national differential item functioning (DIF) is whether the DIF actually reflects a source of bias, or might instead be a methodological artifact reflecting item response theory (IRT) model misspecification.…

Educational organizations in institutionalized environments may try to reflect a legitimate image of the environment in their internal structure. However, there may be loosely coupled relationship between anticipated legitimacy and the performed actions in the schools. Thus, that lack of congruence between rhetoric and the behaviors constitutes…

Designing an effective K-12 alternate English language proficiency assessment (ELP) for English learners with significant cognitive disabilities (ELSCDs) is a substantial undertaking, particularly given the absence of design models for such an assessment and limited empirical research to guide test design teams. These challenges emphasized the…

School-wide positive behavior interventions and supports (SWPBIS) relies on the implementation efforts of frontline service providers such as teachers, administrators, and staff. The full version of the positive behavior interventions and supports--action and commitment tool (PBIS-ACT Full) measures the individual implementer variable of…

Designing and validating a college readiness test addresses the absence of standardized Philippine-based College Readiness Test (CRT) congruent with the College Readiness Standards (CRS) set by the Philippine Commission on Higher Education (CHED). It also resolves the varied and arbitrary indices used by Higher Education Institutions (HEIs) to…

This study provides a comparison of the results of latent class analysis (LCA) and mixture Rasch model (MRM) analysis using data from the Trends in International Mathematics and Science Study -- 2011 (TIMSS-2011) with a focus on the 8th-grade mathematics section. The research study focuses on the comparison of LCA and MRM to determine if results…

This study addresses a gap in the literature on mathematical modeling education by developing the mathematical modeling knowledge scale (MMKS). The MMKS is a quantitative tool created to assess teachers' knowledge of the nature of mathematical modeling. Quantitative instruments to measure modeling knowledge is scare in the literature partially due…

As the standards movement continues into its third decade, there remains a need for alignment methodologies that can be broadly applied to study instruction and policy. This article reports on a series of development efforts meant to revise the Surveys of Enacted Curriculum (SEC) surveys and methods to study the implementation of new college- and…

Current international curriculum frameworks and research advocate for K-12 mathematics to emphasize proof and argumentation. This review synthesizes literature related to conceptions, content, and supportive actions for proof and argumentation across four grade-level bands: K-2, 3-5, 6-8, and 9-12. Our systematic search and subsequent screening…
