Scores estimated from multidimensional item response theory (IRT) models are not necessarily comparable across dimensions. In this article, the concept of aligned dimensions is formalized in the context of Rasch models, and two methods are described--delta dimensional alignment (DDA) and logistic regression alignment (LRA)--to transform estimated…

In this research brief, SRI presents six lessons about equitable scaling from a retrospective study of the Deeper Learning + Diffusion of Innovation and Scaled Impact Initiative (DL+D initiative). Funded by the William and Flora Hewlett Foundation beginning in 2018, the goal of the DL+D initiative was to generate knowledge about how fundamental…

This article reports findings that describe the role that school- and district-based facilitators play in scaling up a published mathematics professional learning program. The study included 12 local facilitators (three teacher leaders and nine staff developers with specialization in mathematics, special education, or English learner education)…

This study shows that residual variation can cause problems related to scaling in exponential random graph models (ERGM). Residual variation is likely to exist when there are unmeasured variables in a model--even those uncorrelated with other predictors--or when the logistic form of the model is inappropriate. As a consequence, coefficients cannot…

Teachers do not directly implement new teaching materials, but rather adapt them. For changing teaching practice, research requires more insights into these adaptions. This study draws on the Theory of Instrumental Genesis to describe the ways teachers adopt the percentage bar model to create different learning opportunities. The results of the…

In this paper, I consider a set of test items that are located in a multidimensional space, S[subscript M], but are located along a curved line in S[subscript M] and can be scaled unidimensionally. Furthermore, I am demonstrating a case in which the test items are administered across 6 levels, such as occurs in K-12 assessment across 6 grade…

Purpose: The purpose of this paper is to report a literature review on sustainability funding in higher education and an analysis of the theoretical influence on academic research. The theoretical contribution and the most influential authors were examined to better understand the intellectual structure that links the theories and authors that…

In this digital ITEMS module, we introduce the framework of nonparametric item response theory (IRT), in particular Mokken scaling, which can be used to evaluate fundamental measurement properties with less strict assumptions than parametric IRT models. We walk through the key distinction between parametric and nonparametric models, introduce the…

The purpose of this study was to use multidimensional scaling (MDS) to investigate relations among scores from the standardization sample of the Wechsler Intelligence Scale for Children--Fifth edition (WISC-V; Wechsler, 2014). Nonmetric two-dimensional MDS maps were selected for interpretation. The most cognitively complex subtests and indexes…

The idea of learning analytics has become popularized within higher education, yet many educators are uncertain about what is entailed when implementing these technologies into practice. The following article serves as an overview to the field of learning analytics for faculty, educators for whom the expectations to use these technologies…

This classroom technology pilot explored the ways in which three different tools yielded insights into instructors' and students' use of physical classroom space in a higher education environment. The tools of interest were a ceiling heatmap camera from Panasonic, small ultrawideband movement trackers from Pozyx, and an audio sensor from TSI. The…

The Washington State Department of Children, Youth, and Families (DCYF) administers and operates a state-funded preschool program called the Early Childhood Education and Assistance Program (ECEAP). To inform systemwide improvements in the program, the department contracted with Education Northwest to conduct a qualitative study of nine sites…

This research was triggered by the identified need in literature for large-scale studies about the kinds of designs that teachers create for mobile learning (m-learning). These studies require analyses of large datasets of learning designs. The common approach followed by researchers when analyzing designs has been to manually classify them…

To develop expertise, novice chemistry students require deliberate practice with immediate and thoughtful feedback. Whereas opportunities for practice are often abundant, opportunities for feedback tend to be much scarcer. To address this challenge, we collaborated with students to develop a flexible and scalable online platform called…

Incivility in the academic arena elicits a wide range of reactions: it interferes with learning, increases stress, feelings of disrespect and helplessness. Although reactions to incivility were mainly tested in workplaces, an extensive, robust framework to explain and measure responses to faculty incivility (FI) is yet to be offered. This study…
