Mathematical modelling competencies have become a prominent construct in research on the teaching and learning of mathematical modelling and its applications in recent decades; however, current research is diverse, proposing different theoretical frameworks and a variety of research designs for the measurement and fostering of modelling…

Word-problem features such as text complexity, charts and graphs, position of the unknown, calculation complexity, irrelevant information, and schemas impact word-problem performance. We compared the word-problem performance of typically achieving (TA) students and students with mathematics difficulty (MD). First, we measured the word-problem…

This Design-based research study aimed to develop a design framework that would help learning designers to apply learning theory principles when designing learning objects. The study examined the experiential learning theory, information processing theory, and cognitive load theory to develop the iterative learning development (ILD) model. Several…

Competency-Based Education (CBE) is proposed as a model that can solve some of higher education's current challenges including the one size fits all approach to student learning. CBE targets this issue by focusing on a student autonomy and personalized learning approaches; however, successful implementation of this requires students have a level…

Research into "gaming the system" behavior in intelligent tutoring systems (ITS) has been around for almost two decades, and detection has been developed for many ITSs. Machine learning models can detect this behavior in both real-time and in historical data. However, intelligent tutoring system designs often change over time, in terms…

Purpose: This study examined the relationship between voice quality and glottal geometry dynamics in patients with adductor spasmodic dysphonia (ADSD). Method: An objective computer vision and machine learning system was developed to extract glottal geometry dynamics from nasolaryngoscopic video recordings for 78 patients with ADSD. General…

Previous research has shown that three comparison types are involved in the formation of students' academic self-concepts: social comparisons (where students compare their achievement with their classmates), dimensional comparisons (where students compare their achievement in different subjects), and temporal comparisons (where students compare…

Reading comprehension is one of the essential skills for students as they make a transition from learning to read to reading to learn. Over the last decade, the increased use of digital learning materials for promoting literacy skills (e.g., oral fluency and reading comprehension) in K-12 classrooms has been a boon for teachers. However, instant…

This article presents the development and application of a model that can be utilized to compare the autonomy of principals in various historical and national contexts. Drawing on former conceptual work on autonomy in education, the model conceptualizes principal autonomy as two-dimensional. The first dimension is the decision making expected from…

Abstract This study proposes a new Bayesian differential item functioning (DIF) detection method using posterior predictive model checking (PPMC). Item fit measures including infit, outfit, observed score distribution (OSD), and Q1 were considered as discrepancy statistics for the PPMC DIF methods. The performance of the PPMC DIF method was…

This paper represents the third in a three-part series intended to challenge the social validity of the services provided by a university-based practicum for addressing the challenging behavior of individuals with disabilities. In this paper, we surveyed referring stakeholders (e.g., parents, teachers) of past service recipients to explore the…

This study aims to evaluate the STEM SOS model based on the opinions of pre-service science teachers. For this aim, the contributions and the challenges of the STEM SOS model to pre-service science teachers were investigated. The participants consisted of 23 pre-service science teachers studying in the 4th grade of science teaching at a state…

The reality is that textbooks and state standards have more content than can reasonably be covered for proficiency in most classrooms. In years past, this typically meant cutting the last unit or two or moving along regardless of who was keeping up, in many cases resulting in cutting statistics from the curriculum. This article provides five…

Determining factors of teachers' intention to use technology is important. Drawing from the Technology Acceptance Model (TAM), we tested a research model depicting the direct and indirect effects of teachers' age, gender, perceived ease of use, perceived usefulness, and attitude towards use of technology on their behavioral intention to use…

Numerous longstanding developmental theories have emphasized the important role that culture and context play in shaping young children's skill development. Nevertheless, the field lacks explicit models describing the extent to which early childhood development may be similar (universal) versus different (specific) across cultures. In this…
