Abstract

The following Course conclusion work (CCW) has the objective to investigate the geometric’s levels thinking of students from the 9º year of the basic education from a public school in Mamanguape/PB city. The used research methodology was an investigative qualitative research of the explorative kind classified as a case study. As theory reference for the investigation we used authors such as Carolino, Curi e Mendonça (2000), Van de Walle(2009), Nasser e Tinoco (2011), Crowley (1987), Brasil(1998). For data collection were applied tests denominated – Van Hiele’s test, where was possible to analyze the level of the geometric development thinking of students from 5 (five) classes from the 9º year of a public school located in Mamanguape/PB. Was applied three Van Hiele test which refer to the level 0 (visualization), 1 (analysis) and 2 (informal deduction). With the collected data was possible to identify how many students from the 5 classes of the 9º year of the referred school, are or not covered in any of the levels of the geometric thinking. With the results were observed that the teaching of geometry are not being possibly worked broadly with those students, whereas the results of the analysed data indicate that no student from the investigated classes are on level 2 (informal deduction).
