Abstract

Students^ ability in geometry is low. So it takes a problem-solving process that looks at the student^s thought process using Van Hiele^s level. The purpose of the study was to find out how students thought process according to Van Hiele^s level in geometry problems, whether there was an improvement, and how to improve the thought process between students who obtained the application of Van Hiele^s in geometry problems and did not. This study was conducted at 2 Langsa State junior high schools with a sample of 32 people. Instruments in the form of tests in the form of description Items amounted to 4 items from level 0 to 3. The results of these tests were analyzed statistically and inferentially. The analysis results obtained there are still many students who are at the level of thinking 0 and 1. The increased analysis obtained the value of F of 12,496 with a significance of 0.001 < 0.05, so Ho was rejected. So it was concluded that there was an increase in the thought process between students who obtained Van Hiele^s application in geometry problems and not. Furthermore, the analysis of how to improve descriptively concluded that the average thought process of students who obtained Van Hiele^s application in geometric problems and not is 20.63. So it is recommended that there be attention to the student^s thought process in Van Hiele^s.
