Determined whether chemistry students (N=332) understood analog tasks that could be used for teaching the mole concept. Also identified possible difficulties that students might have in solving mole problems. Seven major conclusions are reported and discussed, including the finding that two-step problems were more difficult to solve than one-step…

Eight problems in each of three formats were administered to 854 students in grades three through seven. Readers of high ability chose correct operations more often than low-ability readers. The drawn format was easier than the other two formats; its advantage was greater for low-ability readers than high-ability readers. (MNS)

Describes operations research as an important management tool that can aid library managers in effectively using available resources and as a set of analytical tools that can enable researchers to better understand library and information services. Early history, definition, models, applications to libraries, and impact are noted. Twenty-five…

Discusses cultural changes and the meaning of their relationship to medical libraries. Three possible strategies aimed toward creating environment where innovation and risk-taking are encouraged are discussed: create integrative organizational environment; assemble staffs whose collective competencies span necessary roles in innovation process;…

The study with 989 learning-disabled students supported the cognitive-based arithmetic problem-solving model of Dinnel et al. under continuous visual stimulus conditions but suggested a more complex neuropsychological underpinning to arithmetic performance in both visual and aural stimulus conditions.

Presents concept mapping as an effective tool for developing an integrated curriculum. Includes examples of concept maps that represent an entire veterinary curriculum, specific courses, and case-based exercises. (21 references) (Author/JRH)

This article reviews the history of divergent thinking tests and provides a projection of current research suggesting a bright outlook for creativity tests. A model relating problem finding and problem solving is described, as are approaches to increasing test reliability. (DB)

Investigated was the presence and role of cue words in word problems found in three mathematics textbooks series. The methodology and results of the study are presented. Lists of cue words for grades 3-6 are provided. (CW)

Described are how students (n=2,000) reduce the complexity of multivariable problems. Tendencies toward "functional reduction" in common reasoning are shown to range from a simple reduction in the number of variables considered, to a more elaborate procedure where all variables are taken into account, but in a simplified way involving…

This study, which assessed hypothesis-testing abilities using a discrimination-learning paradigm, found that 16 language-impaired primary-level children solved fewer problems than 16 controls equated on cognitive level, but the 2 groups used similar hypothesis types to solve the problems. Type of verbal feedback (explicit versus nonexplicit) did…

This article presents a graduated word problem sequence in mathematics, beginning with simple words; progressing to phrases, sentences, and paragraphs; advancing to paragraph word problems with extraneous information; and finally having students create their own word problems. Results from 67 elementary students with learning disabilities support…

Reanalysis of the data from a 1984 study on making and breaking problem-solving mental sets with 50 children found that gifted subjects who failed to initially form the set made the most errors of any group and were least likely to recognize their own errors. Results suggest that motivational reasons may underly this inferior performance by some…

Three gifted and three learning-disabled gifted students (ages 13-15) viewed themselves on videotape solving mathematical problems and responded to questions pertaining to their problem-solving strategies. The non-learning-disabled students applied substantially more cognitive and metacognitive knowledge to the problem-solving task. (Author/DB)

Conflict-mitigation is a concept and methodology that emphasizes a broad societal understanding of conflicts obtained mainly through in-depth interviewing with many and varied actors. Developed through the work by the Transnational Foundation for Peace and Future Research (TFF), the conflict-mitigation process is intended to serve a number of…

To negotiate a balance between an ideological concern for society's historical-economic development and an understanding of the individual's need for a sense of self-realization, social theory researchers should look to B. Dervin's "gap theory model" of communication. Adapted from Kenneth Burke, it offers a dynamic means of understanding…
