Assessed the relative difficulty in the utilization of oddity and matching response strategies in 144 children, ages 5-13 years. A model of matching and oddity problem-solving is presented based on the data collected. (Author/ED)

Two studies investigated two groups of young children at the ages of four and eight years, respectively. Subjects were required to solve a simple problem task by performing a response opposite to that demonstrated by an adult. Girls' performance was significantly worse than boys', regardless of the sex of the model. (Author/CI)

Seventy-two Ss attempted to solve four "who-done-it" type deductive reasoning problems which varied in mode of representation, type of logical connective employed, and affirmative versus negative statement of information. Affirmative and conjunctive problems were solved more frequently than negative and disjunctive problems (all are defined in the…

Mathematical problem solving has been the focus of much concern. This study investigated the relationship of various cognitive factors, attributions, and gender to the solution of mathematics problems by 100 high school seniors. The independent variables examined in this study included: (1) mathematics knowledge as measured by a score on the…

Analyzed 1.5- and 2.5-year-olds' problem solving and learning. Found that changes in toddlers' strategies could be assessed reliably on a trial-by-trial basis, that changes followed the basic form predicted by the overlapping waves model, and that analyses could reveal information about the qualitative and quantitative aspects of their learning.…

Confirmatory factor analysis was used to test first- and second-order factor models on cognitive abilities and their invariance across samples of 234 male and 225 female secondary school students. Factor models suggest that males and females may use different problem-solving strategies for spatial analogies, matrices, and numerical problems. (SLD)

Differences in critical thinking between undergraduate and graduate students in the social and mathematical sciences was investigated using multiple measures of critical thinking that reflect different types of problem structure. Educational level and academic area differences were found across measures. (Author/MLW)

Relationships between brain-lesion location and behavior in 33 males and 31 females with unilateral lesions were studied. Statistical tests suggest that a single model can describe the relationships for females, but in males separate models of the relationships between lesion location, verbal intelligence quotient, and performance intelligence…

Investigated gender-related differences in the process of solving routine word problems using a nine-step strategy in (n=153) sixth- and (n=149) eighth-grade students. Females were slightly better than males at following the prescribed problem-solving process. Includes test items. (39 references) (MKR)

Describes a study that examined the effect of computer programing experience on the mathematical problem solving achievement of high school students. The variables studied are discussed, including gender, ability, socioeconomic status, prior math experience, and access to a home computer, and a path analysis model is explained. (34 references)…

Recently developed multidimensional-scaling methodology was used to explore the underlying structure of moral reasoning responses to 12 moral dilemmas by 111 graduate students in law and social work and to relate that structure to individual differences. Results indicate that moral reasoning must be viewed from multidimensional and interactional…

This study investigated the effectiveness of a shared, Intranet learning environment on problem-solving ability and reflective metacognition. Subjects were 78 9th and 10th grade biology students from three public high schools in Texas. Research focused on the following questions: (1) Will the use of a shared, Intranet environment improve learner…

The Proceedings of PME-XI has been published in three separate volumes because of the large total of 161 individual conference papers reported. Volume I contains four plenary papers, all on the subject of "constructivism," and 44 commented papers arranged under 4 themes. Volume II contains 56 papers (39 commented; 17 uncommented)…
