The purpose of this study was to explore the psychometric properties of an Arabic translation of the Gifted Rating Scales-School Form (GRS-S) on a national sample of 907 students from Cycle 1 (Grades 1 to 4) and Cycle 2 (Grades 5 to 10) from five governorates in Oman (Muscat, Dhofar, Al-Batinah North, Al-Sharqiyah South, and Al-Dhahira). The…

Research indicates that the performance-gap between English Language Learners (ELLs) and their non-ELL peers is partly due to ELLs' difficulty in understanding assessment language. Accommodations have been shown to narrow this performance-gap, but many accommodations studies have not used a randomized design and are based on relatively small…

This paper reports findings from a project called "The National Panel of Raters" (NPR) that took place within a writing test programme in Norway (2010-2016). A recent research project found individual differences between the raters in the NPR. This paper reports results from an explorative follow up-study where 63 NPR members were…

This study was set to cross-validate a bilingual Persian-English version of the Vocabulary Size Test (VST) against the monolingual English version and compare Iranian EFL learners' performance on the two versions. Various bilingual versions of the VST have been developed based on the assumption that bilingual versions are not affected by the…

Bullying is a serious social problem at schools, very prevalent independently of culture and country, and particularly acute for teenagers. With the irruption of always-on communications technology, the problem, now termed cyberbullying, is no longer restricted to school premises and hours. There are many different approaches to address…

Background: The importance of reading motivation has led to the development of a large number of self-report reading motivation measures; however, there is still a need for a usable measure of adolescent reading motivation that captures a large number of theoretically and empirically distinct constructs. Methods: The current paper details the…

Some scientists believe that speaking a second language could confer lasting cognitive advantages in aging and stave off the onset of dementia (Bialystok et al., 2007; Craik et al., 2010; Abutalebi & Rietbergen, 2014; Grant et al., 2014; Woumans et al., 2015; Klein et al., 2016; Abutalebi & Green, 2016; Smirnov et al., 2019). However, this…

Purpose: High levels of collective teacher efficacy (CTE) within a school is known to be associated with improved student learning. CTE is a marker of the level of shared efficacy among teachers within a school. Knowledge of the levels of CTE within a school does not, though, support its development. To properly support school leaders in nurturing…

The following report describes an assessment instrument called the Mathematics Performance and Cognition (MPAC) interview. The MPAC interview was designed to measure two outcomes of interest. It was designed to measure first and second graders' mathematics achievement in number, operations, and equality, and it was also designed to gather…

This report provides an overview of the development, implementation, and psychometric properties of a student mathematics interview designed to assess first- and second-grade student achievement and thinking processes. The student interview was conducted with 622 first- or second-grade students in 22 schools located in two public school districts…

Planning a mathematics lesson plan is a complex process. Its quality contributes to the effectiveness of mathematics instruction. Given this significance, improving prospective mathematics teachers' lesson planning ability is essential for teacher preparation programs to produce effective teachers. This study examines how a lesson study within a…

Paul E. Newton's article on the consensus definition of validity tackles a number of big issues and makes a number of strong claims. I agreed with much of what he said, and I disagreed with a number of his claims, but I found his article to be consistently interesting and thought provoking (whether I agreed or not). I will focus on three general…

The content validity ratio (Lawshe) is one of the earliest and most widely used methods for quantifying content validity. To correct and expand the table, critical values in unit steps and at multiple alpha levels were computed. Implications for content validation are discussed. (Contains 2 tables and 1 figure.)

A key piece of a validity argument for a language assessment tool is clear overlap between assessment tasks and the target language use (TLU) domain (i.e., the domain description inference). The TOEFL 2000 Spoken and Written Academic Language (T2K-SWAL) corpus, which represents a variety of academic registers and disciplines in traditional…

This study enhanced the 7E instructional model towards enriching the science inquiry skills of senior high school learners in General Chemistry 1. A total of 136 Grade 12 learners enrolled in the Science, Technology, Engineering, and Mathematics (STEM) strand participated in the study. The study was composed of three phases. In Phase I, the…
