Laws and guidelines regulating legal decision making are often imposed without taking the cognitive processes of the legal decision maker into account. In the case of sentencing, this raises the question of whether the sentencing decisions of prosecutors and judges are consistent with legal policy. Especially in handling low-level crimes, legal…

Computerized adaptive testing (CAT) is a mode of testing which enables more efficient and accurate recovery of one or more latent traits. Traditionally, CAT is built upon Item Response Theory (IRT) models that assume unidimensionality. However, the problem of how to build CAT upon latent class models (LCM) has not been investigated until recently,…

The present article provides a primer on using effect sizes in research. A small heuristic data set is used in order to make the discussion concrete. Additionally, various admonitions for best practice in reporting and interpreting effect sizes are presented. Among these is the admonition to not use Cohen's benchmarks for "small," "medium," and…

In three studies we looked at two typical misconceptions of probability: the representativeness heuristic, and the equiprobability bias. The literature on statistics education predicts that some typical errors and biases (e.g., the equiprobability bias) increase with education, whereas others decrease. This is in contrast with reasoning theorists'…

This article gives a general overview of an alternative instructional sequence that can be used to teach integer concepts and operations. The sequence follows three heuristics from Realistic Mathematics Education (RME) that encourage curricula to be reinforced with real-world applications (financial net worth): move students gradually, yet…

Comments on the article by E. Brandstatter, G. Gigerenzer, and R. Hertwig (2006). The authors discuss the priority heuristic, a recent model for decisions under risk. They reanalyze the experimental validity of this approach and discuss how these results compare with cumulative prospect theory, the currently most established model in behavioral…

We study different ways of determining the mean distance (r[subscript n]) between a reference point and its nth neighbour among random points distributed with uniform density in a D-dimensional Euclidean space. First, we present a heuristic method; though this method provides only a crude mathematical result, it shows a simple way of estimating…

This paper considers the often overlooked religious and educational works of the Russian novelist Leo Tolstoy (1828-1910). After outlining Tolstoy's life, religious and educational views, it is argued that Tolstoy has much to offer spiritual educators today. In particular, it suggests Tolstoy's insistence on the absolute and eternal nature of…

A basic problem of daily life is determining who owns what. One way that people may solve this problem is by relying on a "first possession" heuristic, according to which the first person who possesses an object is its owner, even if others subsequently possess the object. We investigated preschoolers' use of this heuristic in five experiments. In…

The purpose of this study was to examine students' understanding of argumentation when talk and writing were provided as learning tools, as well as to explore how talk and writing can best support students' construction of scientific knowledge. Most current studies have examined discourse patterns over a short interval of only a few class periods…

Swirling is an emergent transfer pattern among college students. Swirlers are students who may have participated in a combination of reverse transfer, lateral transfer, or traditional transfer patterns. The available research on swirling has been predominately quantitative in nature. This study was designed to obtain qualitative data on…

There is a limited focus in the literature on wellness and Doctor of Philosophy (PhD) students. The purpose of the present qualitative, heuristic research study was to describe the experience of wellness during the dissertation process. Twelve co-researchers, including the primary researcher, volunteered to answer the research question, "what is…

Basal readers have long been problematized for a lack of diversity among the characters and experiences represented in the text selections. Building on this, and informed by critical theory, critical race theory, and Bourdieuian perspectives, this dissertation examines racist discourses in a set of third grade basal readers. In order to explore…

This case study aimed to determine the nature of student interactions in small groups in an elementary classroom utilizing the Science Writing Heuristic approach. Fifth grade students were audio-recorded over four units of study while working in small groups to generate knowledge claims after conducting student-directed investigations. Analysis…

The New Social Studies movement was an effort by social scientists to reform US social studies/history curriculum at all levels during the 1960s and early 1970s. In the end, more than 50 different projects attempting to revitalise social studies were developed. Many of the projects focused on inquiry-based teaching practices and curriculum.…
