The purpose of this study is to develop a Teachers' Autonomy on Curriculum Scale. For this aim, an item pool consisted of 50-item was prepared for the study. These scale items were reduced to 29 items after expert review and pilot implementation. This preliminary form was applied to 178 science teachers working in secondary schools in Izmir,…

Within the education sector various tools have been used to measure effectiveness of instruction. It is typical that measures of teaching effectiveness include, but are not limited to, the student's perception of their experience in the classroom and with a given instructor. Student evaluations of teaching (SETs) are one form of measurement…

Separation anxiety symptoms are very common in children. The present study aims to examine the psychometric properties and the factorial structure of the Portuguese version of the Separation Anxiety Scale for Children (SASC). The participants included 874 children, 52% male, aged between 8 and 11 years (M = 9.50; SD = 1.15). Factor analysis…

Civil literacy is a concept that enables individuals to act with an awareness about their own rights and responsibilities; to become active in civil life; and to express individual knowledge about the state's management process. Civil literacy is one of the skills that individuals should acquire in learning about the development and change of…

Background: Some electronic cigarette (e-cigarette) users report using these products to quit smoking combustible cigarettes. Purpose: Using the Reasoned Action Approach (RAA), we sought to develop, confirm, and explore a measure of current smokers' intentions, attitudes (instrumental and experiential), social norms (injunctive and descriptive),…

Despite the high prevalence of depression and other mental illnesses in autistic adults, screening instruments such as the Patient Health Questionnaire (PHQ-9) have not been specifically validated in an autistic sample. Using data from two Autism CRC longitudinal studies (n = 581), confirmatory factor analysis supported the two-factor model…

The current study reports the evidence for the reliability (via coefficient [alpha], coefficient [omega]) and validity (via confirmatory factor analysis, correlations) of the Teacher Efficacy for Promoting Partnership measure. Participants were 255 in-service Head Start educators from all Head Start regions across the United States. Educators were…

Background: Prior researchers developed an instrument to measure perceived design thinking ability of first-year students interested in engineering, and they validated the instrument through exploratory factor analysis. Purpose/Hypothesis: Our study uses the previously developed instrument to evaluate perceived design thinking ability of senior…

Recent studies report that students' attitudes toward statistics play an important role in their statistics achievement. The goal of this study was to test the psychometric properties of the "Survey of Attitudes Towards Statistics" (SATS-28) among undergraduate health science students enrolled in an introductory statistics course. Most…

Within mixed methods research, a key issue is how to mix qualitative and quantitative research orientations. Similar debates arise within a mixed method called Q methodology [Q] that has an 80-year history and strong qualitative leanings. Q is often identified with the sorting of statements and the factor analysis (grouping) of people with similar…

The Adapted Skillstreaming Checklist measures social/social-communication skills and behavioral flexibility/regulation of children with autism spectrum disorder without intellectual disability. Prior studies provided support for the reliability and criterion-related validity of the Adapted Skillstreaming Checklist total score for these children;…

This quantitative synthesis combines results of 72 studies that published psychometric information for the Multicultural Counseling Inventory. Although internal consistency, subsample means, and intrascale correlations provide promising evidence, convergent correlations with other instrumentation and factor analyses of validity continue to raise…

The study aimed to develop and validate a test for the measurement of mathematical thinking of secondary-level students. The first-stage aspects of mathematical thinking were explored for a consolidated model in line with the curriculum of secondary-level education in Pakistan. Thirty-six items were developed and piloted in three schools. Factor…

Research-based assessments (RBAs) allow researchers and practitioners to compare student performance across different contexts and institutions. In recent years, research attention has focused on the student populations these RBAs were initially developed with because much of that research was done with "samples of convenience" that were…

Generative artificial intelligence (GenAI) has profoundly reshaped how graduate students conceptualise, design and conduct academic research in higher education. While current metrics predominantly focus on technology acceptance and usage patterns, they often neglect the diverse cognitive engagements in graduate students' integration of GenAI…
