Faculty at institutions of higher education work longer hours and many are burned out and experience low satisfaction and low coping ability. To investigate this phenomenon, this study validated the instrument of Core Self-Evaluations Scale with a sample of higher education faculty members in the U.S., and three different theoretical models (Gu et…

Learning is a continuous process involving teachers, students, materials, and the environment to achieve specific goals. One important aspect of learning is the use of learning media. This study develops a learning media in the form of a magazine on the human circulatory system and an inventory of antihypertensive medicinal plants in Sari Makmur…

Purpose: This study investigated the content and construct validity of the Reflective-Metacognitive Learning (RML) Model, and the effectiveness of the RML Model in comparison with Cognitive-Metacognitive Learning (CML) Model in improving students' metacognitive knowledge, skills, and awareness after the learning process. Methodology: This…

This study aimed to develop the "Lesson Study Model Perception Scale" (LSMPS) and to determine the psychometric properties of the scale. The study was designed as a survey model. A survey model is a research approach that aims to describe a situation as it is. When all the findings obtained to determine the psychometric properties of the…

Much research has been devoted to identification of differential item functioning (DIF), which occurs when the item responses for individuals from two groups differ after they are conditioned on the latent trait being measured by the scale. There has been less work examining differential step functioning (DSF), which is present for polytomous…

This study developed an Adolescents' Uncertainty Scale (AUS), with the aim of understanding individual differences in uncertainty among adolescents. In the pretest phase, 507 ninth-grade students were recruited. After exploratory factor analyses, a 25-item AUS with four dimensions--irresoluteness, instability, lack of self-knowledge, and…

The Cross-Classified Mixed Effects Model (CCMEM) has been demonstrated to be a flexible framework for evaluating reliability by measurement specialists. Reliability can be estimated based on the variance components of the test scores. Built upon their accomplishment, this study extends the CCMEM to be used for evaluating validity evidence.…

The indefinite nature of test fairness and different interpretations and definitions of the concept have stirred a lot of controversy over the years, necessitating the reconceptualization of the concept. On this basis, this study aimed to explore the empirical validity of Kunnan's (2008) Test Fairness Framework (TFF) and revisit the established…

In order to embed blended learning environments in a strategic and sustainable manner, a multi-actor, multidimensional approach is necessary. This paper reports the results of a 3-round Delphi study involving 28 experts which focuses on the refinement and validation of a layered maturity model that assesses key aspects of blended practices in…

This research aims to design immersive virtual reality with cognitive conflict to support practical learning of quantum physics. This type of research is design research through the stages of needs analysis, product design, validity test, and practicality test. The needs analysis used questionnaire sheets distributed with Google Forms and obtained…

Education Transformation in the Industrial Revolution 4.0 era demands early-childhood teachers to possess pedagogical competencies that are not only theoretical but also innovative, creative, and contextual. These competencies are essential for supporting the holistic development of young children, encompassing cognitive, social, emotional, and…

The BIOSEL (Biotechnology Series Learning) model is a learning model that provides opportunities for students to assemble learning through a conceptual description of the coherent and precise steps of Biotechnology implementation. The purpose of this research was to analyze validity and practicality of the BIOSEL model to improve the concept…

Textbooks currently circulating have not been adapted to online learning systems and their contents are less interactive, less communicative, and have not been based on local content potential. This research aimed to produce digital textbooks based on Madura local content and augmented reality to improve students' scientific reasoning ability.…

My dissertation research explored responder behaviors (e.g., demonstrating response styles, carelessness, and possessing misconceptions) that compromise psychometric quality and impact the interpretation and use of assessment results. Identifying these behaviors can help researchers understand and minimize their potentially construct-irrelevant…

When fitting unidimensional item response theory (IRT) models, the population distribution of the latent trait ([theta]) is often assumed to be normally distributed. However, some psychological theories would suggest a nonnormal [theta]. For example, some clinical traits (e.g., alcoholism, depression) are believed to follow a positively skewed…
