PEMECAHAN MASALAH SPASIAL MATEMATIS CALON GURU MATEMATIKA DITINJAU DARI LANGKAH-LANGKAH PEMECAHAN MASALAH POLYA

Abstract

This study aimed to find out the constraints faced by a subject of study in solving spatial problems by applying the general steps of Polya problem solving. The object of study was written answers of completion tests about spatial mathematical problem solving ability created by the subject. Subjects of this study were three students on academic year 2015 / 2016. The data collection used qualitative approach. Analysis is focused on some writing answers by the subject. The weakness of the subject on the spatial problem-solving abilities was seen in error imagination which formed a mental image and imagines the spatial image in visual thinking, so that the subject of women failed to make the spatial transformation correctly. This failure is a problem on spatial visualization ability and would also impact to the failure of solving spatial problems. The results of the inconsistent analysis was found between the analysis of the first test and second, because the quality of the test were different spatially
