Students' self-efficacy is a crucial factor in learning foreign/second language. Although a growing body of literature has drawn attention to the self-efficacy in various fields, very few studies have addressed this issue in the field of foreign language and especially German learning. The purpose of this paper was to develop a reliable and valid…

A poorly elaborated learner's understanding of models has been reported to be one of the major sources for learning difficulties in the quantum domain. To be able to provide physics education in schools with evidence as to how this problem can be tackled, a deeper theoretical understanding of the structure of learners' mental models in quantum…

Though recent advances in research on social class have contributed to our wider understanding of college students' academic and social outcomes, classism in academe remains underexplored across cultures, primarily due to a lack of instruments. The present study discussed the validation of the existing classism measure to assess Korean college…

This study offers methodological synergy in the examination of factorial structure in second language (L2) research. It illustrates the effectiveness and flexibility of the recently developed exploratory structural equation modeling (ESEM) method, which integrates the advantages of exploratory factor analysis (EFA) and confirmatory factor analysis…

The purpose of this research was standardization through a test construction by addressing the assessment of validity and reliability of Reid's English language learning styles among high school students. This research was of quantitative approach. In this paper, 357 (189 females and 168 males) high school students in Isfahan Province on 2013-2014…

Vocational interest inventories play an important role in supporting adolescents and young adults in their vocational choice. However, existing verbal and pictorial questionnaires have limitations regarding the complexity, abstraction level, and ambiguity of the item material. The presented research attempts to overcome these limitations by…

The aim of this study is to develop a valid and reliable measurement tool that measures critical thinking skills of university students. Pamukkale Critical Thinking Skills Scale was developed as two separate forms; multiple choice and open-ended. The validity and reliability studies of the multiple-choice form were constructed on two different…

The relationship between a teacher and a student is directly related to both teacher and student satisfaction and success. The purpose of this study was to develop a valid and reliable Teacher--Student Relational Efficacy Scale (TSRES)--an instrument to provide measurable and research-based reflective opportunity to identify and potentially…

The purpose of this mixed-methods research was to develop and validate an instrument to measure teacher self-efficacy for teachers of students with visual impairments (TSVIs). The researcher used a six step process for survey development and validation, which included 1) literature review; 2) a preliminary qualitative study; 3) synthesis of…

The challenge that existed in the Fall of 2020 was not knowing exactly how students and teachers could adapt to a new way of teaching and learning amidst a world-wide pandemic. There has long been a debate over the effectiveness of online versus face-to-face teaching. The researcher found insufficient research so far has been done on the…

In this dissertation, I complete three studies to evaluate potential reactions to target role congruity, especially gender role congruity, through an examination of Student Evaluations of Instructors (SEIs). Target role congruity refers to assessments an observer makes of whether or not the various roles a target person fills "fit" with…

This study investigates the performance of robust maximum likelihood (ML) estimators when fitting and evaluating small sample latent growth models with non-normal missing data. Results showed that the robust ML methods could be used to account for non-normality even when the sample size is very small (e.g., N < 100). Among the robust ML…

In this study, different factor analysis models were employed to test the Self-Compassion Scale (SCS) in 11 distinct populations (n = 15,266) in different countries. The results strongly suggest that the most appropriate use of the SCS is to measure levels of Self-Compassionate responding (positive items) and Self-Uncompassionate responding…

This study aimed to adapt the Cognitive Emotion Regulation Strategies for Children Scale (CERQ-k) developed by Garnefski et al. (2007) into Turkish, and to carry out validity and reliability studies of the Turkish version for children aged between 9-12. The research was carried out with 657 students attending a Middle School in Istanbul's Pendik…
