In this study we measured changes in science teachers' conceptual science understanding (content knowledge) and pedagogical content knowledge (PCK) while participating in a problem-based learning (PBL) model of professional development. Teachers participated in a two-week long workshop followed by nine monthly meetings during one academic year…

The authors present a stakeholder-driven method, the earliest anticipated timeline of impact, which is designed to assess stakeholder expectations for the earliest time frame in which social programs are likely to affect outcomes. The utility of the anticipated timeline of impact is illustrated using an example from an evaluation of a…

E. J. Wisniewski and G. L. Murphy (see record EJ689195) suggested that the apparent effects of relation frequency in C. L. Gagne and E. J. Shoben's (1997) conceptual combination experiments could be explained by differences between the familiarity and plausibility of their stimuli (noun-noun phrases). However, C. L. Gagne and T. L. Spalding argued…

The existing vector formalism method for thermodynamic relationship maintains tractability and uses accessible mathematics, which can be seen as a diverting and entertaining step into the mathematical formalism of thermodynamics and as an elementary application of matrix algebra. The method is based on ideas and operations apt to improve the…

Chinese brush calligraphy is a valuable civilization legacy and a high art of scholarship. It is still popular in Chinese banners, newspaper mastheads, university names, and celebration gifts. There are Web sites that try to help people enjoy and learn Chinese calligraphy. However, there lacks advanced services such as content-based retrieval or…

In this work is proposed that an adaptation tool that is for the automatic generation and personalization of courses of a general-purpose LCMS that is named A Tutor. A Tutor is a Learning Content Management System. The architecture of the adaptation tool that allows a personalized sequencing of LOs in A Tutor for the learner's learning goals,…

This study explores concepts of learning used by leaders, focusing on learning for leadership through day-to-day workplace experiences. The participants were drawn from the senior management team within a school, the chair of governors of the school and the local authority school improvement advisor. Concept mapping was used as a participatory…

Electronic game technologies can prepare novice learners for future learning of complex concepts. This paper describes the underlying instructional design, learning science, cognitive science, and game theory. A structural, or syntactic mapping (structure mapping), approach to game design can produce a game world relationally isomorphic to a…

This article traces the roots of narrative research in the social sciences and education, then centers on "story constellations," a version of narrative inquiry that uncovers teachers' knowledge of school reform in context. A fluid form of investigation that unfolds in a three-dimensional inquiry space, story constellations consists of a flexible…

Not all demonstrations involve using exciting visual displays of one or a series of scientific principles. Demonstrations can be as simple as showing the interrelationship between scientific concepts or principles using concept maps. Concepts maps are tools that help people conceptualize and remember a conglomeration of facts making up complex…

Research on the qualities and characteristics that individuals value in those from whom they seek "career help" is very limited. Existing studies provide little insight into the meaning behind the labels individuals use to identify valued qualities and characteristics. We address this neglected area using qualitative interviews based on life story…

Novak and Iuli [Novak, J. D. & Iuli, R. J. (1991). The use of meta-cognitive tools to facilitate knowledge production. In "A paper presented at the fourth Florida AI research symposium (FLAIRS '91)," Pensacola Beach, FL, May, 1991.] discuss the use of Concept Maps as meta-cognitive tools that help people to think about thinking. This work…

This article proposes a theoretical framework to study organizational embeddedness and occupational embeddedness. Organizational embeddedness is the totality of forces (fit, links, and sacrifices) that keep people in their current organizations, while occupational embeddedness is the totality of forces (fit, links, and sacrifices) that keep people…

This paper discusses the use of ontologies and their applications to assessment. An ontology provides a shared and common understanding of a domain that can be communicated among people and computational systems. The ontology captures one or more experts' conceptual representation of a domain expressed in terms of concepts and the relationships…

The validity of connected understanding interpretation of three concept mapping techniques was studied, focusing on the correspondence between mapping-intended task demands, inferred cognitive activities, and scores obtained. The concurrent and retrospective verbalizations of subjects at different levels of competency as they performed the mapping…
