When exposed to principal components analysis for the first time, students can sometimes miss the primary purpose of the analysis. Often the focus is solely on data reduction and what to do after the dimensions of the data have been reduced is ignored. The datasets discussed here can be used as an in-class example, a homework assignment, or a…

This study proposes a multi-informant (youth, teachers, and parents) measure of relationship quality with adults for youth with intellectual disabilities (ID). A sample of 395 youth with mild (49.15%) and moderate (50.85%) ID, aged 11-22 (M = 15.82) was recruited in Canada (French-speaking, N = 142), and Australia (English-speaking, N = 253).…

Purpose: Working memory and linguistic knowledge are highly intertwined in language tasks. Verbal working memory in particular has been studied as a potential constraint on language performance. This, in turn, highlights the need for a clinical assessment tool that will assist clinicians in understanding individual children's performance in…

The aim of this study is to develop a measurement tool for self-efficacy perception to support early literacy skills. In the study, an item pool of 60 items was created by considering the relevant literature. The form was presented to the field experts who had studies in the relevant fields, and 5 items in the item pool of the scale were removed…

The contemporary era of learning-oriented assessment (LOA) demands teacher professional efforts to appropriately and accurately assess learners' attainment and use the assessment results for the enhancement of learning. In second/foreign language (L2) discipline, this has recently brought language assessment literacy (LAL) to the forefront,…

School climate research has traditionally been carried out by separating its two main components, prosocial and antisocial behaviors. This is often a partial view of the school climate. Hence, the goal of this study is to develop an evaluation instrument (CONVIVE) that takes into account both perspectives of the school climate through a…

Burnout is psychological, physical, and emotional suffering that may affect students with low or inadequate resources to face stressful events at school. Although the existing instruments are used worldwide to assess school burnout risk, they show several flaws and mainly focus on the emotional facets of the syndrome. No previous studies have…

Twenty-first-century skills are considered to be critical to student development. The present study aimed to validate a scale that reflects 21st century skills in education. The participants were 982 students in the fourth, fifth, and sixth grades at two primary schools in a large city in Shandong, China, who were all asked to learn English in a…

Prior research has demonstrated the important role of chemistry students' affect in academic performance. Likert-scale surveys are the most prevalent tools to measure students' affect within chemistry education research, however, data collected through a Likert-scale survey may exhibit response style bias which can hinder accurately measuring…

Despite the strong criticisms, mass student surveys play an important role in the quality assurance process of national higher education systems. While some national higher education systems have a long history of using student surveys to inform teaching and course quality improvement (e.g. the UK, Australia), in Italy, where the quality assurance…

In linguistically diverse contexts, language repertoires include various literacy skills in multiple languages across different modes of representation (multiliteracies), where multilingual writing can be conceptualized as a synthesized competence that includes all languages in a person's repertoire and is continuously evolving. We respond to the…

This study developed a Self-Regulated Second Language Self-Study Questionnaire that addresses the self-regulated learning (SRL) skills of learners of English as a foreign language in a self-study setting. Much attention has been paid to SRL in second language acquisition; however, contexts outside school have hardly been explored. To address this…

Early learning interventions are widely implemented in developing countries yet instruments to reliably measure the effects of such programs on children's development and learning in specific contexts are needed. This study examines the measurement properties of a globally-informed instrument adapted to measure school readiness in Laotian children…

This study examined the psychometric properties of the Ego Resiliency Scale-Revised (ER89-R). Though support exists for a multidimensional conceptualisation using classical test theory approaches (i.e., a higher-order model comprising Openness to Life Experiences and Optimal Regulation factors), this measure has not been subjected to Rasch…

Studies on students' motivation to learn Chemistry in developed countries are largely common in the literature. However, very few studies have been carried out with a view to investigating students' motivation to learn Chemistry in places like Latin America, and specifically in Brazil. The present study sought to translate the Chemistry Motivation…
