Most current accounts of color word acquisition propose that the delay between children's first production of color words and adult-like understanding is due to problems abstracting color as a domain of meaning. Here we present evidence against this hypothesis, and show that, from the time children produce color words in a labeling task they use…

Chemistry students encounter a variety of terms, definitions, and classification schemes that many instructors expect students to memorize and be able to use. This research investigated students' descriptions of ionic and covalent bonding beyond definitions in order to explore students' knowledge about chemical bonding. Using Johnstone's Multiple…

Much research has demonstrated a shape bias in categorizing and naming solid objects. This research has shown that when an entity is conceptualized as an individual object, adults and children attend to the object's shape. Separate research in the domain of numerical cognition suggest that there are distinct processes for quantifying small and…

The ability to classify the political leaning of a large number of articles and items is valuable to both academic research and practical applications. The challenge, though, is not only about developing innovative classification algorithms, which constitutes a "classifier" theme in this thesis, but also about how to define the…

State education agencies (SEAs) are central players in initiating and leading new reform efforts. However, traditional approaches to providing public information are not adequate for producing the necessary awareness and support to implement reforms statewide and at the local level. SEAs often have very few staff or other resources devoted to…

We introduce a new statistical procedure for the identification of unobserved categories that vary between individuals and in which objects may span multiple categories. This procedure can be used to analyze data from a proposed sorting task in which individuals may simultaneously assign objects to multiple piles. The results of a synthetic…

Two recent lines of research suggest that explicitly naming objects at study influences subsequent memory for those objects at test. Lupyan (2008) suggested that naming "impairs" memory by a representational shift of stored representations of named objects toward the prototype (labeling effect). MacLeod, Gopie, Hourihan, Neary, and Ozubko (2010)…

How do explaining and prior knowledge contribute to learning? Four experiments explored the relationship between explanation and prior knowledge in category learning. The experiments independently manipulated whether participants were prompted to explain the category membership of study observations and whether category labels were informative in…

People are capable of imagining and generating new category exemplars and categories. This ability has not been addressed by previous models of categorization, most of which focus on classifying category exemplars rather than generating them. We develop a formal account of exemplar and category generation which proposes that category knowledge is…

This study aimed to analyze curriculum evaluation studies conducted in foreign language education between the years 2005 and 2016 in terms of the levels the studies were conducted in, sample groups, sample size, research methods and curriculum evaluation models via descriptive content analysis. Searching various data bases, 87 studies, which are…

From 2005-2010 the province of Alberta introduced a social studies program of study mandating that all K-12 teachers use the lens of First Nations, Metis, and Inuit perspectives to help students understand the past as well as key concepts and contemporary issues. This paper offers a systematic examination of a range of data sources, including…

In compliance with the provisions of A.C.A.§ 6-20-2201 et seq., the Annual Statistical Report of the Public School of Arkansas, Open Enrollment Public Charter Schools, and Education Service Cooperatives, 2016-2017 Actual and 2017-2018 Budgeted, (ASR) is hereby submitted. The Rankings of Selected items of the Public Schools of Arkansas, 2016-2017…

The current study aims to determine science student teachers' cognitive structure on the concept of food chain. Qualitative research method was applied in this study. Fallacies detected in the pre-service teachers' conceptual structures are believed to result in students' developing misconceptions in their future classes and will adversely affect…

Attention allocation in word learning may vary developmentally based on the novelty of the object. It has been suggested that children differentially learn verbs based on the novelty of the agent, but adults do not because they automatically infer the object's category and thus treat it like a familiar object. The current research examined…

This article draws on ethnographic research that examines the contemporary articulation of class identity in the postcolonial elite school setting of Old College high school in Barbados. From the qualitative data derived from this study, we argue that social class is better conceived as a series of flows, mutations, performances and performatives.…
