| Sumario: | The objective of this article is to present the investigation realizedabout the knowledge of high school students on defining attributes of theconcept of polygon. The participatings of the study were 253 students of highschool, who answered a test of defining attributes, and six of them were selectedfor individual interviews, kind of semi-conducted, that they were audio-recordedand transcripted for analysis. The results showed that the general average (M =6,0), in the test of defining attributes, was low and that the statistic test pointedout the significative differences (p < 0,05) in the percentages of rights in fouraffirmations from the 14 which were analysed. However the test did not presentsignificative differences among the average of each series. The analysis alsoshowed that the interviewed people had difficulties to identify three definingattributes of polygons: flat figure, straight line segments and simple figure. |
