"The results indicate that anxiety interacts with irrelevant information to produce a difficult situation for the problem solver. (Author)

Reports on an exploratory study to examine problem formulation and to isolate factors that influence it. Four areas were addressed: how organizations become aware of problems, the methods of inquiry, the influence of managers, and the emergent themes that characterize problem formation in organizations. (Author/IRT)

Three alternative solutions available for analysis of variance (ANOVA) using two-way and three-way completely randomized factorial designs with disproportional cell sizes across all two-way and three-way summary tables with no empty cells are discussed. These solutions are categorized as unique, sequential, and experimental. The procedures used,…

Information obtained in this study involving 72 girls (6-, 9-, and 12-year-olds) documents the facilitating effect of forced verbalization at three age levels. (Author/WY)

A statistical technique designed to highlight the contributions of two continuous predictor variables to a continuous criterion variable is described. The technique involves selecting subpopulations, called pockets, via regression techniques. An example using cognitive styles to predict performance on problem-solving tasks is discussed.…

This study examined problem solving as a function of display type (table/graph) and numeric function (linear/nonlinear) in four problem solving domains. Twenty-two stimulus problems were developed, and line graph and table displays were constructed for each problem. Half of the displays contained linear numeric functions and the other half…

Statistical methods are discussed for studying relations between two sets of variables, when each set contains more than one variable. (Author)

"Relations among preschool children's preference for color and form attributes speed of learning an initial problem, and optional shift behavior in discrimination training, were examined in this study supported by the National Institutes of Health. (Author)

The problem-solving performance of elderly individuals was facilitated by manipulating the demands of problem-solving tasks. The fact that elderly individuals can use more efficient strategies under certain circumstances suggests that the elderly have such strategies in their repertoires. (Author)

Describes a study of undergraduates that investigated the effects of providing access to a case library of related stories while solving ill-structured problems. Describes experimental, comparable, and control group treatments and discusses results of multiple-choice tests and short answer questions. (Author/LRW)

ACCORDING TO PIAGET, THE CONCEPT OF CONSERVATION IS A PREREQUISITE TO MATHEMATICAL UNDERSTANDING. THIS STUDY SOUGHT TO DETERMINE WHETHER THE ABILITY OF FIRST GRADE CHILDREN TO SOLVE ADDITION PROBLEMS WAS DEPENDENT ON THEIR MASTERY OF CONSERVATION OF NUMEROUSNESS. SECONDARY PURPOSES WERE TO INVESTIGATE THE EFFECT IN PROBLEM STATEMENTS OF (1)…

Perceptual and cognitive development were investigated in two recall tasks with 48 Ss from each of the grades kindergarten, third, and sixth. (Author)

This study extended concepts derived from Rothkopf's mathemagenic hypothesis to problem solving. While previous mathemagenic research has established that adjunct questions interspersed with written prose facilitates learning, it has been criticized as educationally nonsignificant because the research has focused on verbatim learning. To test…

This study assessed the effects of learning logo computer programing and computer-assisted instruction (CAI) on specific cognitive skills, metacognitive skills, creativity, and achievement. The programing group scored significantly higher on measures of operational competence, two of three measures of metacognitive skills, and a measure of…
