To help in interpreting the polarity of a molecule, charge separation can be visualized by mapping the electrostatic potential at the van der Waals surface using a color gradient or by indicating positive and negative regions of the electrostatic potential using different colored isosurfaces. Although these visualizations capture the molecular…

This article examines the connections of linear algebra concepts in a first course at the undergraduate level. The theoretical underpinnings of this study are grounded in the constructivist perspective (including social constructivism), Vernaud's theory of conceptual fields and Pirie and Kieren's model for the growth of mathematical understanding.…

Professionals in the field of addictions view problems associated with recovery management across multiple domains. This exploratory study utilized concept mapping and pattern matching methodology to conceptualize the resulting 7 domains of concern for treatment and aftercare of problem and pathological gamblers. The information can be used by…

Comments on a article by Dewsbury (February-March 2009) in which he stated, "Darwin provided a viable mechanism for evolutionary change, natural selection" (p. 67). Although this view is consistent with the modern synthesis, the author argues that (a) the natural selection "mechanism" provided by Darwin was not initially accepted by scientists…

This study explored the potential effect of college students' self-generated computerized mind maps on their reading comprehension. It also investigated the subjects' attitudes toward generating computerized mind maps for reading comprehension. The study was conducted in response to the inability of the foundation-level students, who were learning…

Teaching students to use and interpret representations in science is critically important if they are to become scientifically literate and learn how to communicate their understandings and learning in science. This study involved 248 students (119 boys and 129 girls) from 26 grade 6 teachers' classes in nine primary schools in Brisbane,…

This dissertation examines the way in which sonnets improved reading comprehension through a case study. The study was conceptually framed around the ideas of the New Critics, who employed two particular fallacies to ensure the most accurate reading of literature. The purpose of the study was to see the potential benefits that could come from…

Domain adaptation of natural language processing systems is challenging because it requires human expertise. While manual effort is effective in creating a high quality knowledge base, it is expensive and time consuming. Clinical text adds another layer of complexity to the task due to privacy and confidentiality restrictions that hinder the…

A critical review of research to date suggests a need to explore the development of graduate student research capacity from the standpoint of graduate students. Six members of an interdisciplinary graduate student colloquium at the Centre for Youth and Society (Victoria, Canada) offer their perspective. Our research involved four phases, each…

The purpose of this research is threefold: (1) to identify the difficulties that Grade 10 students in a Lebanese school have that hinder their conceptual understanding at the micro-macro-symbolic interface in chemistry, (2) to investigate the effect of a macro-micro-symbolic teaching approach on students' relational understanding of chemical…

Published articles permit mapping international and comparative education research. We reviewed 605 articles published 2004-2008 in four major journals. Using title, abstract, and entire text we explored thematic focus, geographic focus, level/type of education studied, method, and funding. The economic, political, and social context of education…

Drawing on cartography, urban design and visual data modelling, we consider how people navigate, or fail to navigate, the mental, physical and social spaces of knowledge communities. Cartographically inspired critical thinking offers opportunities to re-examine the assumptions and formal maps of post-secondary institutions, visualizing…

Research apprenticeships for secondary students provide authentic contexts for learning science in which students engage in scientific investigations with practicing scientists in working laboratory groups. Student experiences in these research apprenticeships vary depending on the individual nature of the laboratory in which students have been…

A fundamental goal of critical literacy approaches is to bring a change and empower students as critical agents and subjects of decision making. Students are expected to do more than simply accumulate information; they are encouraged to challenge their "taken for granted" belief structures and transform themselves as well as their…

Four physiology courses participating in a science education program used concept maps for the first time. At the conclusion of the term, students responded to an end-of-term survey about the activity. Following varied results, we sought to identify factors that students indicated are important for the acceptance of the technique. To encourage…
