Among all, Cronbach's Alpha and McDonald's Omega are commonly used for reliability estimations. The alpha uses inter-item correlations while omega is based on a factor analysis result. This study uses simulated ordinal data sets to test whether the alpha and omega produce different estimates. Their performances were compared according to the…

Persistent in mathematical studies is an important element allowing students to be successful in their STEM careers, and there is a need for affective measurement instruments to assess persistence in mathematics in spite of problems. For this reason, this study aims to adapt the Mathematical Resilience Scale developed to assess resilience, which…

The Test of Early Mathematics Ability-Third Edition (TEMA-3) is a commonly used measure of early mathematics knowledge for children aged 3 years to 8 years 11 months. In spite of its wide use, research on the psychometric properties of TEMA-3 remains limited. This study applied the Rasch model to investigate the psychometric properties of TEMA-3…

The Metacognitive Self-Regulation scale (MSR) was recently improved after subjecting the scale to a comprehensive reanalysis and replacing it with the Metacognitive Self-Regulation Revised scale (MSR-R). However, up to this point, researchers have made no attempts to determine if the MSR or MSR-R performs equivalently for males and females. The…

The Emotional and Behavioral Screener (EBS) is a recently developed teacher-reported brief screening instrument for identifying students who are at-risk of an emotional or behavioral disorder (EBD). Although prior research supports the technical adequacy of scores from the EBS, there is a gap in the literature regarding strong evidence of the…

Increased understanding of the importance of the affective domain in chemistry education research has led to the development and adaptation of instruments to measure chemistry-specific affective traits, including motivation. Many of these instruments are adapted from other fields by using the word "chemistry" in place of other…

The purpose of the present study was to adapt and validate the Need for Cognition Scale--Short Form (NfC-SF) in the Greek language. A multistep process was followed, including (a) the translation and adaptation of the questionnaire, (b) a reliability analysis of the instrument's items in combination with an exploratory factor analysis with 177…

The main purpose of this study is to hypothesize the existence of the general sense of role satisfaction and device a scale to measure it. The participants in study 1 were 1029 Japanese high school students (484 men and 545 women). The result of exploratory factor analysis suggested that the two-factor structure is adequate. One is "social…

Student resistance, which can briefly be defined as the tendency to resist teaching activities, is student's reacting to the teaching-learning activities, teachers, or administrators knowingly and wilfully, many times intentionally in various ways. Resistance behaviours, which could be considered as the outpouring of the anger created by the…

Effects of rating scale forms on cross-sectional reliability and measurement equivalence were investigated. A randomized experimental design was implemented, varying category labels and number of categories. The participants were 800 students at two German universities. In contrast to previous research, reliability assessment method was used,…

Introduction: The focus of our research converges on the analysis of attitudes and the prediction of the behavior of university students towards the inclusion of students with disabilities in university. The evaluation of attitudes and the prediction of behavior are complex, but it is fundamental because of the decisive impact they have on the…

This study, in the framework of the Positive Educational Psychology, has two objectives: to perform a psychometric analysis of the Satisfaction with Life Scale, and to compare the resulting values according to gender, age and educational institution, in a group of schoolers from the city of Arequipa. We worked with a sample of 872 students in the…

Purpose: This study examined the development and validation of the Effectiveness Scale of Child Familial Influencing Behavior. This measurement is constructed to evaluate the effectiveness of child familial influencing behaviors within three-generational relationships. Methods: The effectiveness of child familial influencing behaviors was rated by…

The purpose of this study was to adapt the Sources of Middle School Mathematics Self-Efficacy Scale developed by Usher and Pajares to Turkish culture. This scale assesses Bandura's theorized sources of self-efficacy among mathematics students in middle school. After the Turkish version of the scale was formed, it was applied 6th, 7th and 8th…

The purpose of this study was to develop a test to determine spatial ability of middle school students. The participants were 704 middle school students (6th, 7th and 8th grade) who were studying at different schools from Istanbul. Item analysis, exploratory and confirmatory factor analysis, reliability analysis were used to analyse the data.…
