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…

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…

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.

The present study is an attempt to construct an information processing skills scale for higher secondary students. Information processing skills scale was developed and standardized based on the theoretical concept "Information skills in the school" engaging learners in constructing knowledge by State of New South Wales, Department of…

Raters must score accurately and consistently for classroom observation scores to be valid. This requires (a) a standard defining when scoring is accurate and consistent enough and (b) measuring and remediating rater performance against that standard. Current practice has focused on this second problem to the exclusion of the first. My goal here…

Purpose of this study is to adapt Behavioral Regulation in Sports Questionnaire (BRSQ) which developed by Lonsdale, Hodge and Rose (2008) in Turkish and review psychometry properties. The scale consists of 24 items and 6 subdimension including intrinsic motivation, integrated regulation, identified regulation, introjected regulation, external…

This article reports on the development of a custom-made questionnaire. The questionnaire was developed with the aim to compile guidelines for the professional development (PD) of mathematics teachers for the pedagogical use of information and communication technology (ICT) integration in teaching and learning. During the standardisation and…

From a theoretical perspective, most discussions of statistical learning (SL) have focused on the possible "statistical" properties that are the object of learning. Much less attention has been given to defining what "learning" is in the context of "statistical learning." One major difficulty is that SL research has…
