AB - <p>The study was conducted with 50 grade 9 students, using 8 questions related to the vertex and the side length of the cube to evaluate the students' spatial reasoning about two-dimensional representations, focusing on spatial analysis reasoning and spatial visualization reasoning. The spatial reasoning shown in the students' answers was quantified in the study. The results show that the students' spatial reasoning was above average but not high. The proportion of students answering based on visual observations was still high. Most students used spatial analysis reasoning or a combination of spatial visualization and spatial analysis reasoning, but rarely used only spatial visualization reasoning to solve. Students' reasoning about individual vertex or line segments is better than reasoning about problems that combine both.</p>
