In this paper, we investigate two purported problems with Bayesian Knowledge Tracing (BKT), a popular statistical model of student learning: "identifiability" and "semantic model degeneracy." In 2007, Beck and Chang stated that BKT is susceptible to an "identifiability problem"--various models with different…

This article focuses on designing and conducting action research in diverse settings. Action research is a collaborative approach to problem solving. It involves consultative problem identification, reflects context, encourages reflexive examination, and ultimately encourages and empowers beneficiaries for desirable change. In that regard, it puts…

Background: Stratified medicine seeks to identify patients most likely to respond to treatment. Individual participant data (IPD) network meta-analysis (NMA) models have greater power than individual trials to identify treatment-covariate interactions (TCIs). Treatment-covariate interactions contain "within" and "across" trial…

The ability of novice instructional designers to become skilled problem-solvers, who select and apply appropriate instructional design (ID) models in their work environments, are key competencies generally sought after in introductory ID courses. Yet, the proliferation of ID models, coupled with varied philosophies and practices about how ID is…

The Math Teachers' Circle (MTC) model is a widely implemented form of professional development that invites teachers to become practitioners of mathematics, thereby developing their fluency with mathematical practices. This article presents comparative case studies investigating the self-reported experiences of several MTC-participating teachers…

The Research Skill Development (RSD) framework was devised in 2006 to articulate what educators do when they facilitate student learning through active exploration in ways that enable their skills to grow in sophistication and rigour. This special issue of JUTLP comprises eight articles that focus on the critique, adaptation and application of the…

One of the central goals of modern science and chemistry education is to develop students' abilities to understand complex phenomena, and productively engage in explanation, justification, and argumentation. To accomplish this goal, we should better characterise the types of reasoning that we expect students to master in the different scientific…

This research aims to explore the concept of mental model of students about genetic concepts through drawing-writing test. The participants were 85 students of Biology Education at University of Lampung, which has taken genetics course. Mental model of students was categorized into five levels (levels 1-5) based on coding framework which was…

Accurately modeling individual students' knowledge growth is important in many applications of learning analytics. A key step is to decompose the knowledge targeted in the instruction into detailed knowledge components (KCs). We search for an accurate KC model for basic equation solving skills, using data from an intelligent tutoring system (ITS),…

Age-period-cohort (APC) models are designed to estimate the independent effects of age, time periods, and cohort membership. However, APC models suffer from an identification problem: There are no unique estimates of the independent effects that fit the data best because of the exact linear dependency among age, period, and cohort. Among methods…

It is not typically the bent of infrastructure to be continually responsive in a way that is expansive and inclusive; instead, for newcomers or those with alternative histories, aims, vision, values, and perspectives, the inertia of infrastructure is more likely to be experienced as infrastructural breakdowns. We ask: "What might wisdom look…

The authors examine how the profession's adaptation to Flexner's criteria influences the emergence of the neomedical model as the majoritarian paradigm within social work even in the face of a pluralism manifest by the existence of other competing paradigms. One endorses empowerment in social work, and the other embraces societal transformation in…

Positive behaviour support (PBS) has become well established as an intervention approach for individuals with intellectual disability and challenging behaviour. However, what remains unexplored is the relationship between PBS and the medical and social models of disability, which historically are the dominant conceptual frameworks put forward in…

Over the last three decades, the study of test preparation and test washback has emerged as an indispensable area of inquiry in language assessment. Yet, how test takers' motivation and perceptions of test design and content might mediate test preparation has not been given sufficient attention. Taking the general English module of a high stakes…

The current industrial revolution demands a revolution on teaching methodologies at all levels, particularly for higher education. Here, we present an efficient model to teach technologies associated with Industry 4.0 (I4.0) in undergraduate engineering courses. The first step was identifying the main skills required for an I4.0 practitioner and…
