Teaching is a complex endeavor that requires deep knowledge of content, pedagogy, and students. Educational stakeholders design teacher competence frameworks to outline the knowledge, skills, and dispositions that teachers need to have to improve their teaching activity. These competence frameworks are guided by research and theory and tend to…

In April 2021, the Midwestern Higher Education Compact (MHEC) convened a working group of institution, state, and national leaders to help advise its efforts to develop a set of principles to improve consistency and reliability in the field for measuring cost savings and the return on investment (ROI) of open education resources (OER). The result…

It is important to consider the two parameters of signal detection theory, discriminability and response bias, when evaluating eyewitness identification from simultaneous lineups. On the basis of the diagnostic feature-detection hypothesis, we tested a method for increasing discriminability that encourages eyewitnesses to carefully rank each…

We examined how mushroom experts organize and process their knowledge, compared with novices, and which types of arguments they use to process information. Mushroom experts and novices carried out an identification/memorization task, a free recall task, and a matching task. Results showed that experts performed better than novices on all three…

The present study aims to compare the robustness under various conditions of latent class analysis mixture modeling approaches that deal with auxiliary distal outcomes. Monte Carlo simulations were employed to test the performance of four approaches recommended by previous simulation studies: maximum likelihood (ML) assuming homoskedasticity…

In this article, a large data set containing every course taken by every undergraduate student in a major university in Canada over 10 years is analysed. Modern machine learning algorithms can use large data sets to build useful tools for the data provider, in this case, the university. In this article, two classifiers are constructed using random…

Undergraduate students usually study Laurent series in a standard course of Complex Analysis. One of the major applications of Laurent series is the classification of isolated singular points of complex functions. Although students are able to find series representations of functions, they may struggle to understand the meaning of the behaviour of…

Changes in Supervised Agricultural Experiences (SAEs) and a lack of SAE category knowledge have been identified as causes to declining SAE participation (Dyer & Osborne, 1995; Steel, 1997; Wilson & Moore, 2007). Recently, the National Council for Agricultural Education and the National FFA Organization have redefined SAE and created new…

How does improving children's ability to label set sizes without counting affect the development of understanding of the cardinality principle? It may accelerate development by facilitating subsequent alignment and comparison of the cardinal label for a given set and the last word counted when counting that set (Mix et al., 2012). Alternatively,…

In the current research, we tested the idea that the proximity of contrasting categories in a learning sequence would determine the features to which participants attend in a categorization task. For the first experiment, we designed a 4-category structure in which pairs of categories could be perfectly distinguished using 1 feature. Two of the…

Previous research has shown that when learning categories, adults and young children allocate attention differently. Adults tend to attend selectively, focusing primarily on the most relevant information, whereas young children tend to distribute their attention broadly. Although selective attention is useful in many situations, it also has costs.…

The van Hiele theory and van Hiele Geometry Test have been extensively used in mathematics assessments across countries. The purpose of this study is to use classical test theory (CTT) and cognitive diagnostic modeling (CDM) frameworks to examine psychometric properties of the van Hiele Geometry Test and to compare how various classification…

Propensity score (PS) adjustments have become popular methods used to improve estimates of treatment effects in quasi-experiments. Although researchers continue to develop PS methods, other procedures can also be effective in reducing selection bias. One of these uses clustering to create balanced groups. However, the success of this new method…

Learning naturalistic categories, which tend to have fuzzy boundaries and vary on many dimensions, can often be harder than learning well defined categories. One method for facilitating the category learning of naturalistic stimuli may be to provide explicit feature descriptions that highlight the characteristic features of each category. Although…

In this article, we seek to apply Julie Thompson Klein's supple understanding of typology as both category-making and category-defying to one aspect of her own body of work: her participation in a range of organizations with permeable boundaries. Specifically, we review her contributions to theories of boundary work in interdisciplinary studies…
