Student growth percentiles (SGPs) are currently used by several states and school districts to provide information about individual students as well as to evaluate teachers, schools, and school districts. For SGPs to be defensible for these purposes, they should be reliable. In this study, we examine the amount of systematic and random error in…

The protection of earth's biodiversity requires a sophisticated understanding of how human activities can affect the relative abundances of species in natural ecological communities. Here, we report on an introductory biology laboratory activity in which students quantified biodiversity while investigating one of the most important controls on the…

Humans are sensitive to the properties of individual items, and exemplar models are useful for capturing this sensitivity. I am a proponent of an extension of exemplar-based architectures that I briefly describe. However, exemplar models are very shallow architectures in which it is necessary to stipulate a set of primitive elements that make up…

This study problematizes the global educational governance of OECD PISA and its statistical data as a governing technology in contemporary discourses of education reforms. The study examines principles that order the discourses and practices of the international comparative assessment. The effort of analysing the impact of an education reform…

Building conceptual knowledge that generalizes to novel situations is a key function of human memory. Category-learning paradigms have long been used to understand the mechanisms of knowledge generalization. In the present study, we tested the conditions that promote formation of new concepts. Participants underwent 1 of 6 training conditions that…

Despite numerous efforts to improve geographical teacher training, student teachers often develop inert theoretical knowledge during their studies. Teachers' deeply rooted implicit orientations concerning geography classes, which are important for future classroom practice and professional learning at university, are a major reason for the theory…

Research synthesis on simple yet general hypotheses and ideas is challenging in scientific disciplines studying highly context-dependent systems such as medical, social, and biological sciences. This study shows that machine learning, equation-free statistical modeling of artificial intelligence, is a promising synthesis tool for discovering novel…

This study examined the perception of an ASD label compared to Asperger's syndrome or no diagnosis. Seventy-one undergraduates read an adapted vignette (Ohan et al. J Autism Dev Disord 45:3384-3389, 2015) about an undergraduate with ASD, Asperger's Syndrome, or No Diagnosis. Participants also completed questionnaires. More positive ratings emerged…

Randomized controlled trials are not always feasible in educational research, so researchers must use alternative methods to study treatment effects. Propensity score matching is one such method for observational studies that has shown considerable growth in popularity since it was first introduced in the early 1980s. This paper outlines the…

Students' solutions of enumerative combinatorial problems may be assessed along two main dimensions: the correctness of the solution and the method of enumeration. This study looks at the second dimension with reference to the Cartesian product of two sets, and at the 'odometer' combinatorial strategy defined by English (1991). Since we are not…

The aim of this study is to examine the level of individual innovation and the professional innovativeness tendencies of the primary school teacher candidates. Scanning model was used in the research. The population of the study consists of 192 primary school teacher candidates studying in the faculty of education. Kiliçer and Odabasi's (2010)…

Our goal in this article is to organise an epistemological matrix for the concept of rational number that contemplates its different meanings. Aiming at understanding the various ways to signify the rational numbers and based on the theoretical-methodological approach of conceptual profiles, we produce and analyse data from various sources,…

Over the past decades, reports from official authorities and the media have suggested that there is a 'crisis' in young people's mental health. However, there is considerable uncertainty regarding how to interpret the data referred to in these alarming reports. The present article draws on 'the minority voices' of young people and theories…

Using data provided in "ProQuest: Dissertations and Theses: Global" (PQDTGlobal) database from 1890 to 2016, in this study we explore gender differences in historical and contemporary trends in public administration doctoral dissertation research in the United States. Our analysis reveals that not only has the number of women completing…

There is an increasing attention to the phenomenon referred to as "twice exceptional" ("2e") children, namely, children who demonstrate both exceptional abilities and disabilities. In this essay, this concept is applied to delinquency and/or emotional-behavior disorder and gifts (talents) in the performance arts, exploring the…
