Analysis of spatial ability of class VIII students Institute Indonesia Yogyakarta Problem Based Learning on topic of cuboids and cubes

Abstract

The goals of this research were (1) to describe implementation of learning about cuboids and cube nets by using problem based learning (PBL), (2) to describe the spatial ability (spatial representation) of students by using problem based learning about cuboids and cubes nets. The type of research is design research. The research subjects were 28 grade VIII SMP Institute Indonesia Yogyakarta. Data was collected using field notes, documentation and results/answer of LKS 1, LKS 2. The data analysis technique used is qualitative descriptive. The research was conducted in March 2019. The research about the learning process by using problem based learning. The results of the research show that the learning design made in this research is good and the spatial ability of grade VIII students SMP Institut Indonesia Yogyakarta in making cuboids and cubes nets have fulfilled the first indicator (1). This is indicated by the majority of students able to describe cuboids and cubes nets. In addition, some students have not fulfilled the second indicator about identifying cuboids and cubes nets.
