This study aims to explore all the types of students' mental models of number patterns. The study used a qualitative approach with an explorative type. The subjects used to characterize the student's mental models in this study were 46 eighth grade students in Indonesia. To reveal the subjects' mental model, they were asked to solve the number…

Although we can support Heyes' call for more research on mechanisms, we disagree that the problem has been ignored as Heyes suggests. We also doubt that basic learning mechanisms are alone sufficient to account for the broad range of findings in the selective social learning literature. Although phylogenetically shared learning mechanisms must…

Teachers are required to use evidence-based practices while teaching their students with autism spectrum disorder. However, there is considerable research suggesting that they need professional development (PD) to use evidence-based practices. Therefore, research needs to search for effective and efficient PD alternatives have arisen nearly during…

Among the variety of selected response formats used in L2 reading assessment, multiple-choice (MC) is the most commonly adopted, primarily due to its efficiency and objectiveness. Given the impact of assessment results on teaching and learning, it is necessary to investigate the degree to which the MC format reliably measures learners' L2 reading…

Functional communication training (FCT) is a strategy to address problem behavior for students with various disabilities that is supported by a broad evidence base. Despite this support, multiple factors continue to dissuade educators from utilizing FCT in their classrooms. This article outlines the process of developing and implementing FCT plans…

Geometry education is an important aspect of STEM education and career development, but it is often overlooked in K-12 education in the United States. Although there is some research on teaching geometry to students with learning difficulties at the elementary level, there is a lack of research on teaching advanced geometry skills at high school…

Conjectures are a key component of mathematical inquiry, a process in which the students raise conjectures, refute or dismiss some of them, and formulate additional ones. Taking a design-based research approach, we formulated a design principle for personal feedback in supporting the iterative process of conjecturing. We empirically explored the…

Large scale international assessments depend on invariance of measurement across countries. An important consideration when observing cross-national differential item functioning (DIF) is whether the DIF actually reflects a source of bias, or might instead be a methodological artifact reflecting item response theory (IRT) model misspecification.…

Although abstraction is widely understood to be one of the primary components of computational thinking, the roots of abstraction may be traced back to different fields. Hence, the meaning of abstraction in the context of computational thinking is often confounded, as researchers interpret abstraction through diverse lenses. To disentangle these…

A great deal of research on second language (L2) input has provided useful linguistic evidence for the development of generalizations about and hypotheses on the usage-based nature of L2 knowledge. However, despite the fact that classrooms are one of the most ubiquitous sites of L2 learning, we still know very little about the linguistic quality…

Learning progressions have become an important construct in educational research, in part because of their ability to inform the design of coherent standards, curricula, assessments, and instruction. In this paper, I discuss how a learning progressions approach has guided our development of an early algebra innovation for the elementary grades and…

Isomorphism and homomorphism appear throughout abstract algebra, yet how algebraists characterize these concepts, especially homomorphism, remains understudied. Based on interviews with nine research-active mathematicians, we highlight new sameness-based conceptual metaphors and three new clusters of metaphors: sameness/formal definition, changing…

Most speech-language pathologists (SLPs) in Malaysia practice with an undergraduate degree, which provides them with limited knowledge about and training in augmentative and alternative communication (AAC). This limited knowledge and training may affect their confidence and competence when introducing and using AAC with individuals for whom it is…

Generalisation is a skill that enables learners to acquire knowledge in general, and mathematical knowledge in particular. It is a core aspect of algebraic thinking and, in particular, of functional thinking, as a type of algebraic thinking. Introducing primary school children to functional thinking fosters their ability to generalise, explain and…

The aim of this study is to analyse the importance of the number of raters and compare the results obtained by techniques based on Classical Test Theory (CTT) and Generalizability (G) Theory. The Kappa and Krippendorff alpha techniques based on CTT were used to determine the inter-rater reliability. In this descriptive research data consists of…
