This paper describes the design and evaluation of the Organic chemistry Representational Competence Assessment (ORCA). Grounded in Kozma and Russell's representational competence framework, the ORCA measures the learner's ability to "interpret," "translate," and "use" six commonly used representations of molecular…

The problem of local item dependencies (LIDs) is very common in personality and attitude measures, particularly in those that measure narrow-bandwidth dimensions. At the structural level, these dependencies can be modeled by using extended factor analytic (FA) solutions that include correlated residuals. However, the effects that LIDs have on the…

The creation and implementation of innovation proposals in education can provide a new key towards sustainable development. We are aware that schools perform very different innovations but often, with very low levels of impact and dissemination in their community. There are not many studies that describe, put a value on, categorize or analyse the…

Maladaptive perfectionism has a documented association with mental health problems, yet the context of maladaptive perfectionism (i.e., the domain where individuals exhibit such a trait) is rarely considered. This study aimed to develop a measure for academic perfectionism among college students and assess its psychometric properties. Five hundred…

I created the 15-item Learner-Centered Syllabus Scale (LCSS) based on the work of Cullen and Harris. The purpose of this study was to assess the factor structure, reliability, and validity of the LCSS. Four blind coders assessed 175 syllabi using the LCSS with 92% inter-rater agreement. To establish concurrent validity, each blind coder rated the…

Composite reliability, or coefficient omega, can be estimated using structural equation modeling. Composite reliability is usually estimated under the basic independent clusters model of confirmatory factor analysis (ICM-CFA). However, due to the existence of cross-loadings, the model fit of the exploratory structural equation model (ESEM) is…

Introduction: Inspiration is a concept that is used in different disciplines; however, there is no instrument that measures its impact in the academic sphere. In this sense, the present study aims to develop and validate a measurement instrument for academic inspiration (AIS). Method: A total of 7,871 university students from different careers…

Inquiry learning is a powerful strategy to instill scientific thinking into the student. Therefore, it was aimed to develop a scale of inquiry learning skills towards geometry in this study. The study was designed according to a scanning model. The study group was determined according to the convenience sampling method. 514 middle school students…

One of the objectives of education is to provide diverse pupils with proper educational opportunities. It is anticipated that the night instructors will have this equipment. In this study, validity, and reliability evaluations of the scale to be used to identify digital competence in prospective instructors to support children with functional…

In this study, it is aimed to improve the "Creativity-Supporting Home Environment Scale" for the purpose of determining the level of creativity in the home environment of parents with children aged 3-6 years old. Research study groups were composed of 500 parents across various provinces of Turkey. The scale items written in the context…

During the COVID pandemic, the sudden switch to online learning brought an unintended spotlight to this gradually expanding educational innovation. However, while numerous tools exist to assess student perceptions of or readiness for online learning quantitatively, a research gap exists regarding teachers' perceptions of online learning. To…

The ability to read and understand scientific information is necessary for the growth of a scientific society. Moreover, the reasons why they want to study different scientific fields are diverse. The validity and reliability of the Science Motivation Scale in Russia were investigated for this study. The first step was to determine whether or not…

In STEMNET's report, 76% of 500 teachers interviewed stated that joining the STEM Club increased students' ability to solve real-world problems. This study aims to develop a valid and reliable measurement tool for evaluating STEM clubs. The research sample consisting of 149 teachers who carry out STEM club activities in schools in Turkey was…

In recent years, computational thinking has been considered as one of the 21st century skills that all students should have. Researchers emphasize the importance of determining and developing students' computational thinking levels from the earliest possible age. However, no measurement tool has been found in the literature that aims to reveal the…

This study is an attempt to develop a reliable and valid measurement tool to measure secondary school students' attitudes towards metaverse use. Therefore, the study reported the analyses related to metaverse attitude scale (MVAS). The content validity of the scale was ensured by an expert's view, and Exploratory Factor Analysis (EFA) and…
