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…

This study represents an initial examination of the potential of word dictation (WD), a form of curriculum-based measure, to identify risk in writing for young English language learners (ELs). The sample included 73 ELs with beginning to advanced English language proficiency in the first to third grades attending schools in one U.S. Midwestern…

This study aims to investigate: (1) the construct validity of the "Blended Learners' Online Component Challenges" BLOCC scale; (2) the internal reliability of the scale; and (3) the differences between blended learners' online component challenges according to different socio-demographic variables for Sport Science students. The sample…

Self-regulated learning (SRL) is a critical component of mathematics problem-solving. Students skilled in SRL are more likely to effectively set goals, search for information, and direct their attention and cognitive process so that they align their efforts with their objectives. An influential framework for SRL, the SMART model (Winne, 2017),…

Disciplinary climate and opportunity to learn (OTL) are considered as effectiveness-enhancing factors that can improve mathematics achievement. In this study, we investigated whether the school-level aggregation of student-reported OTL could yield reliable and valid measures, and then explored the relationships among disciplinary climate, OTL, and…

As multi/plurilingual research advances understandings of plurilingual speakers' fluid language use, particularly in multilingual settings, new research methods and pedagogical orientations that address this complex phenomenon are needed. The present study considered the development, reliability, and validity of the Plurilingual and Pluricultural…

The objectives were to examine the factorial structure of the Academic Procrastination Scale-Short Form (APS-S) and the measurement invariance across gender and educational levels, to determine possible differences in procrastination across gender, educational levels, and grades. The sample was formed of 1486 Spanish primary and secondary school…

In 2016, the Office of the Higher Education Commission issued a directive requiring all higher education institutions in Thailand to have their students take a standardized English proficiency test. According to the directive, the test's results had to align with the Common European Framework of Reference for Languages (CEFR). In response to this…

Intercultural Teaching Competence (ITC) is essential for teaching in increasingly diverse primary schools. However, research has not sufficiently addressed the meaning and development of ITC, including whether study abroad during teacher education contributes to the dimensions included. Therefore, this study seeks to determine which dimensions of…

The study examines reliability and validity evidence of observational systems for evaluating teacher effectiveness and fostering professional development conversations in schools. Specifically, this study compared the Framework for Teaching's (FFT) validity evidence using the traditional scoring approach with a new composite scoring approach that…

Three studies (N = 1,346) detail the development of three theoretically grounded instruments operationalizing "instructor strictness." Using open-ended questionnaire data (n = 427), study 1 inductively derives an understanding of the instructor behaviors that students perceive as strict. These patterns of behavior are then condensed into…

The purpose of this study is to develop Education Value Perception Scale (EVPS) based on Bronfenbrenner's Ecological Theory and to investigate its psychometric properties according to Classical Test Theory (CTT) and Item Response Theory (IRT). The data were collected from 2872 secondary school students by stratified purposeful sampling method.…

This study introduces the signal weighted teacher value-added model (SW VAM), a value-added model that weights student-level observations based on each student's capacity to signal their assigned teacher's quality. Specifically, the model leverages the repeated appearance of a given student to estimate student reliability and sensitivity…

Much of the science reported in the media depends on correlation coefficients. But the size of correlation coefficients depends, in part, on the reliability with which the correlated variables are measured. Understanding this is a statistical literacy issue.

This study describes the development and initial psychometric evaluation of a Recognizing Effective Special Education Teachers (RESET) teacher observation instrument. Specifically, the study uses generalizability theory to compare two versions of a rubric, one with general descriptors of performance levels and one with item-specific descriptors of…
