RESUMO

This study aimed to verify the existence of relationships between cognitive styles and strategies of problem solving, cognitive styles and the variables gender and grade, cognitive styles and student performance in problem solving, as well the performance and type of strategy used in solving problems. To this end, was asked 168 students to the first, second and third grade of High School from two public schools that responded to a questionnaire information, a Likert type scale to categorize the cognitive styles, and a mathematical test, addressing the concepts and procedural algebraic and arithmetic. Through analysis of cognitive styles in relation to this study, the predominance of divergence on the convergence of thought. And from the analysis of means of variables, cognitive style and gender, the means obtained indicated that women compared to men, had a higher prevalence in the styles Reflective and Serialist and lower in cognitive styles Impulsive and of Field-Independence. Both gender were predominant style Field-Dependent, Serialist, Reflective. There was still significant differences in cognitive styles, when considering the series of study revealed between the groups according to cognitive style Convergent, Dependent, Serialist and Reflective, indicating that the cognitive styles vary depending on the student s age. It was also noted that all relations between the variables cognitive styles and performance in mathematical test are below 0.3, indicating weak correlations, it is not possible to affirm the existence of relations between them. We also observed the existence of relationships between student performance on the mathematical test and strategies of problem solving, indicating that the "forward strategy", the most used by the subjects, proved adequate to solve the problems proposed the study. Regarding the existence of possible relationships between cognitive styles and strategies of problem solving, there was a unique relationship founded between the style Reflective and strategies of problem solving used in problem A, the male sample. Regarding females there were 6 low intensity correlations (r <0.3), and although relations were low intensity, can be considered that there is a tendency for females to present relationships between variables style and strategies. Despite these results, it is necessary a further analysis in relation to cognitive styles and strategies used in an attempt to explain the causes of the relationships found, even that low. For these findings, we emphasize the importance of replicating this study in larger samples to confirm or not the results.
