The Suicide Screening Tool for Chronic Illness assesses suicide risk for persons with chronic, "invisible" illnesses. From an initial pool of 31 items, internal consistency, Rasch, and exploratory and confirmatory factor analyses produced a 14-item scale that is unidimensional, internally consistent, and correlated with measures of…

As chemistry education, and science education more broadly, have shifted to emphasize realistic scientific practices as an important component of education, a number of researchers have used the Students' Understanding of Models in Science (SUMS) instrument to assess students' knowledge about scientific models and modelling. SUMS has also been…

The current study investigated Student-Teacher Relationship Measure (STRM) psychometric properties using Rasch analysis in a sample of middle school female students (N = 995). Rasch Principal Components Analysis revealed psychometric support of two subscales (i.e., Academic and Social Relations). Summary statistics showed good psychometric…

The aim of this study is to develop a measurement tool to measure the attitude towards story writing. Validity and reliability studies of the scale, applied to 243 secondary school students, were carried out with exploratory factor analysis, measurement of internal consistency and confirmatory factor analysis. EFA revealed that the scale had three…

Objective Structured Clinical Examinations (OSCEs) have become ubiquitous as a form of assessment in medical education but involve substantial resource demands and considerable local variation. A detailed understanding of the processes by which OSCEs are designed and administered could improve feasibility and sustainability. This exploration of…

The instrument that assesses teachers' competence on AR methodology is limited. Thus, it is one of the issues concerning evaluating the effectiveness of a professional development program on designing AR projects. It is difficult to determine how much and what teachers have learned in a course or training. Thus, this cross-sectional study aimed to…

This study aimed to examine the measurement invariance of the mathematical affective characteristics model obtained from TIMSS 2015 4th grade Turkey administration according to home resources. For this purpose, firstly, the factor structure of the mathematical affective characteristics questionnaire was examined by explanatory factor analysis and…

Rational Numbers is an essential topic in mathematics since it necessitates the learning progression of more advanced topics. Nevertheless, previous literature shows that students are having difficulties in understanding the topic for numerous reasons. The inability of teachers in providing good examples during teaching is identified as one of the…

It is important to improve the literacy skills of students who learn Turkish as a foreign language. Especially the development of writing skills has a vital role in gaining literacy skills. Therefore, the aim of this study is to develop a scale that can measure the writing anxiety of students who learn Turkish as a foreign language. For this…

Despite their experience, teachers continuously need to develop themselves professionally as the recency of the knowledge they acquire in teacher education programmes wears off in time -- which means they need to be autonomous enough take responsibility for their own professional learning. This study, therefore, defines 'teachers' professional…

This study aimed to investigate the validity of the Cognitive and Metacognitive Learning Strategies Scale (CMLSC) for mathematics learning in Chinese context. Exploratory and confirmatory factor analysis, reliability analysis, measurement invariance across gender groups, and criterion-related validity were conducted on 698 Chinese senior secondary…

This study developed a measure of solidarity levels during pandemics, the Solidarity in Pandemics Scale (SPS). This was achieved using a study group of 842 individuals aged between 18 and 65 from different segments of society who had experienced the COVID-19 pandemic and differed in age, gender, and socioeconomic status. Exploratory factor…

Cognitive control skills in early life are vital to success throughout the lifespan. Such skills have been positively linked to a host of important short- and long-term outcomes across many diverse domains. Similarly, self-perceptions such as self-efficacy, implicit beliefs about cognition, and self-concept have all been shown to predict…

The Fowler Diet Cola Test (DCT) was originally developed to assess the scientific process skills of students in science classrooms. The use of the test is generally suggested for gifted students in science. There are considerable number of Scientific Process Skills (SPS) tests that the researchers developed for different student population. The…

Massive open online courses (MOOCs) can potentially affect the lives of millions of people, but there is little research on how a programming MOOC could affect participants' lives after participation. In Estonia, we have organised several programming MOOCs over the years, attended by over 14,000 people. This inspired us to develop and validate a…
