This paper, which is based on two years of ethnographic fieldwork with a young female refugee-background student, attends to the evolution of the student's math identity shortly after arrival to the U.S. More specifically, it highlights the ways in which the student's background knowledge and competence with the subject impacted her performance…

Data visualization is a powerful strategy for using graphics to represent data for effective communication and analysis. Unfortunately, creating effective data visualizations is a challenge for both novice and expert design users. The task often involves an iterative process of trial and error, which by its nature, is time-consuming. Designers…

Purpose: Poor sleep is associated with short-term dysregulation of mood and is a risk factor for major depressive disorder (MDD). This study examines whether objectively measured sleep in late adolescence prospectively predicts major depressive episode (MDE) onset in early adulthood as well as whether daily affect mediates this association.…

A number of assessment methods are used to improve teaching which accelerates students' achievement. This study investigates the effect of two assessment methods (Think - Pair - Share and Choral Response) on academic achievement of prospective science teachers in a public sector university in Lahore, Pakistan. It employed a quasi-experimental…

Teacher work engagement is critical for work performance and child development, yet there is a limited understanding of how it is shaped from the perspective of teachers' emotion. Based on the job demand-resource model, this study tested the relationship between emotional labor strategies, teacher efficacy, grit, and work engagement. Research…

We develop a "latent variable forest" (LV Forest) algorithm for the estimation of latent variable scores with one or more latent variables. LV Forest estimates unbiased latent variable scores based on "confirmatory factor analysis" (CFA) models with ordinal and/or numerical response variables. Through parametric model…

The pattern of behaviors and abilities that reflect the core characteristics of students with autism spectrum disorder (ASD) and an environment that lacks the ability to understand individuals with ASD can make these students targets of bullying. Bullying is a serious problem for students with ASD, and practices against it are important in terms…

The Texas Education Agency (TEA) has implemented a student accountability system that measures students' performance on the State of Texas Assessment for Academic Readiness (STAAR) in several content areas. Therefore, teachers and administrators all over the state are always seeking ways to ensure that students are academically well prepared.…

Background: Personalised and timely feedback in massive open online courses (MOOCs) is hindered due to the large scale and diverse needs of learners. Learning analytics (LA) can support scalable interventions, however they often lack pedagogical and contextual grounding. Previous research claimed that a human-centred approach in the design of LA…

The Chairs of Conflict Resolution (CoCR) is a process developed for training children to discuss their conflicts constructively so they experience win-win outcomes. The present study examines the discussion taking place during the use of CoCR with young children 4-6-years-old. The discussion between the two children proceeded in four phases: (a)…

In this study, we introduced a cross-classified multidimensional nominal response model (CC-MNRM) to account for various response styles (RS) in the presence of cross-classified data. The proposed model allows slopes to vary across items and can explore impacts of observed covariates on latent constructs. We applied a recently developed variant of…

In learning analytics and in education at large, AI explanations are always computed from aggregate data of all the students to offer the "average" picture. Whereas the average may work for most students, it does not reflect or capture the individual differences or the variability among students. Therefore, instance-level…

This study examines how second/foreign language (L2) word difficulty estimates derived from item response theory (IRT) and classical test theory (CTT) frameworks are virtually identical in the context of vocabulary testing. This conclusion is reached via a two-stage process: (a) psychometric assessments of both approaches and (b) L2 word…

This study investigated whether infants encode better the features of a briefly occluded object if its movements are specified simultaneously by vision and audition than if they are not (data collected: 2017-2019). Experiment 1 showed that 10-month-old infants (N = 39, 22 females, White-English) notice changes in the visual pattern on the object…

In this paper we develop a case for introducing a new teaching tool to undergraduate mathematics. Lean is an interactive theorem prover that instantly checks the correctness of every step and provides immediate feedback. Teaching with Lean might present a challenge, in that students must write their proofs in a formal way using a specific syntax.…
