Improving Student Geometry Problem-Solving Skills Through Spatial Training

Abstract

Problem-solving is an integral part of learning mathematics, and geometry is one of the basic subjects of mathematics. However, students' geometric problem-solving skills are relatively lacking due to some factors, including spatial skills. There is a significant relationship between spatial skills and problem-solving. Therefore, spatial training needs to be implemented in schools to improve students' geometric problem-solving skills. This study aimed to determine the improvement of students' geometric problem-solving skills through spatial training. The research employed a quantitative method. The participants were 8th-grade students from one of the junior high schools which consisted of 30 students. The research instrument was a test of geometry problem-solving skills. Data on students' geometry problem-solving skills were analysed using paired t-test and normalised N-gain. The results showed that there was an increase in students' geometric problem-solving skills through spatial training. It can be said that spatial training can improve students' geometry problem-solving skills. This research implies that spatial training can be carried out ongoingly to achieve better learning outcomes.
