Conceptual Understanding: "What is Studentd Spatial Thinking Design in Geometry Learning?"

Data for Classification indicators of spatial thinking.

The change of paradigms in national assessment in 2021 became a particular issue for teachers in improving student competencies. The main issue encountered by teacher is the way to improve student competencies in mathematic learning, especially in geometry. This writing is aimed to outline spatial thinking indicators with six relevant background components of realistic geometry, and to describe students' spatial spatial thinking design to acquire a geometric comprehension by using google sketch-up. The spatial thinking indicators are outluned with six background components of realistic geometry by using explanatory factor analysis (EFA) with JASP software 0.15.0.0. The acquires research results show the correlations between sighting and projecting, orienting and locating, transforming, constructing and drawing, measuring and calculation, and spatial reasoning variables. Spatial thinking indicators are outlined in six component groups of realistic geometry. The results ca be used as the consideration for teachers in identifying students conceptual understanding to support the improvement of student competencies.
