As a prominent aspect of modeling learners in the education domain, knowledge tracing attempts to model learner's cognitive process, and it has been studied for nearly 30 years. Driven by the rapid advancements in deep learning techniques, deep neural networks have been recently adopted for knowledge tracing and have exhibited unique advantages…

Latent class models with covariates are widely used for psychological, social, and educational research. Yet the fundamental identifiability issue of these models has not been fully addressed. Among the previous research on the identifiability of latent class models with covariates, Huang and Bandeen-Roche (Psychometrika 69:5-32, 2004) studied the…

Cognition could be seen as a cascade of top-down and bottom-up processes across behavioural and psychophysiological layers in a cognitive architecture. Typical behavioural measurements used in education do not give information about lower cognitive layers. Event-Related Potentials (ERPs) derived from electroencephalography allow researchers to…

This article proposes a class of cognitive diagnosis models (CDMs) for polytomously scored items with different link functions. Many existing polytomous CDMs can be considered as special cases of the proposed class of polytomous CDMs. Simulation studies were carried out to investigate the feasibility of the proposed CDMs and the performance of…

For 40 years there has been a call for improvement in assessing the academic potential of children and young people (CYP) with visual impairment. Anecdotal evidence regarding the use of psychometric assessments with CYP with visual impairment suggests that some professional practice has involved the use of assessments normed on a sighted…

Albert Beckham, who was the first Black school psychologist in the U.S., frequently used intelligence tests with Black children. This usage required clinical decision making to explain the results obtained from psychoeducational assessments. In their discussion of this aspect of Beckham's work, introduce the concept of Culturally Relevant Clinical…

This paper presents the concepts and observations in the author's keynote address at the May 2019 "Opportunity versus Challenge: Exploring Usage of Log-File and Process Data in International Large-Scale Assessments" conference in Dublin, Ireland. This paper recaps briefly some key points that emerged at the December 2018 ETS symposium on…

Although there exist a range of professional standards and guidelines for evaluating individuals from diverse linguistic and cultural backgrounds, there is a conspicuous absence of approaches that meet or satisfy the recommendations related to fairness and equity, particularly with reference to English learners (ELs). ELs are defined simply as…

This book is a testament to the increasing role and importance of multiple source use in everyday and academic literacy activities in the 21st century. How should we introduce the topic of multiple sources here? For most readers, we need not, because this chapter is not their first literacy stop in the volume, so the topic has been adequately…

We review the GIDNA and CDM packages in R for fitting cognitive diagnosis/diagnostic classification models. We first provide a summary of their core capabilities and then use both simulated and real data to compare their functionalities in practice. We found that the most relevant routines in the two packages appear to be more similar than…

Since Miyake and his colleagues (2000) published their seminal paper on the use of confirmatory factor analysis (CFA) to parse executive function (EF), CFA methods have become ubiquitous in EF research. In their interesting and thoughtful Focus article, "Executive Function: Formative Versus Reflective Measurement," Willoughby and…

Higher-order factor analysis is a widely used approach for analyzing the structure of a multidimensional test. Whenever first-order factors are correlated researchers are tempted to apply a higher-order factor model. But is this reasonable? What do the higher-order factors measure? What is their meaning? Willoughby, Holochwost, Blanton, and Blair…

The European Union has seen an increased number of asylum seekers and economic migrants over the past few years. There will be request to assess some of these individuals to see if they have an intellectual disability (ID). If this is to be done using the current internationally recognized definitions of ID, we will need to be confident that the…

The authors of the Focus article pose important questions regarding whether or not performance-based tasks related to executive functioning are best viewed as reflective or formative indicators. Miyake and Friedman (2012) define executive functioning (EF) as "a set of general-purpose control mechanisms, often linked to the prefrontal cortex…

The focus article (Willoughby et al., 2014) (1) introduced the distinction between formative and reflective measurement and (2) proposed that performance-based executive function tasks may be better conceptualized from the perspective of formative rather than reflective measurement. This proposal stands in sharp contrast to conventional…
